What is liquid insulation. Liquid insulation for interior and exterior walls in an apartment. Components, manufacture and application of "penoizol"

28.02.2021 Complications

Today, there is a so-called liquid thermal insulation on the market, but still this is slang, and not the name of the material. In terms of its composition, liquid thermal insulation is rather a mastic with the consistency of sour cream. It is applied with a brush or roller on a surface that has been previously cleaned of dust and dirt.

The composition of liquid thermal insulation includes several components: glass ceramics, vacuum, dioxides and latex mixtures. Manufacturers claim that 1 mm. Liquid insulation will be replaced by 50 mm. traditional thermal insulation. But in order to achieve really such indicators, it is necessary to apply 10-12 layers of liquid thermal insulation.

Many argue that they used liquid insulation on the walls inside the room to insulate it and to isolate it from the appearance of mold. The very fact of wall insulation from the inside is already incorrect, since a dew point arises between the insulation and the wall, which leads to the appearance of condensation.

This is still a delusion, it can be used as a waterproofing, and then only external without active action, i.e. instead of roofing material on the roof, it will not work. But if you cover the junction between the wall and the visor, in order to avoid water getting on the wall, it will do quite well. It is possible to cover the piping to eliminate condensate and increase their service life.

By the way, the use of this mastic is advisable in the coating of pipelines, since its service life is about 20 years and liquid thermal insulation is not subject to destruction by ultraviolet irradiation. In Europe, it has long been used for painting bridges, but they call it paint, not liquid insulation.

Therefore, it is impractical to insulate the walls with liquid thermal insulation, since it is necessary to apply 10 layers. The price of such thermal insulation will be cosmic, it is better to use EPS. Every material has its own area of ​​application, do not be fooled.

Comparative prices for liquid thermal insulation:

The average price for many manufacturers is about $ 15 per liter. liquid waterproofing. Consumption for 1 m² (with a layer thickness of 1 mm.) - 1 liter, and the price of 1 m² of foam (50 mm thick.) - $ 3. Hence, it is possible to draw a conclusion about the "space" technology not only in the understanding of the invention.

Liquid insulation is one of the most discussed technologies in modern construction. Manufacturers claim that with its help it is possible to qualitatively insulate surfaces of any type without loss of usable area and unnecessary time and physical costs.

The principle of operation of liquid insulation

At its core, it is a high-tech paint with excellent thermal insulation properties. It is also called warm paint. An acrylic binder is used as a base, in addition, the composition contains silicone and / or ceramic calibrated microspheres. The content of microspheres in heat paint can be up to 80%. It is thanks to these inclusions that air gaps are created that provide a thermal insulation effect. The presence of fixers, catalysts and other additives creates conditions for uniform and easy application, as well as high adhesion and durability. In addition, the composition may contain additives that will protect the treated surface from damage by corrosion and mold.

The tasks that liquid insulation solves

  • External thermal insulation of the building, as well as the facades of houses of complex architectural forms, panel risers, balconies.
  • Internal thermal insulation of walls in cases where the thickness of the insulation is critical.
  • Insulation of pipelines, anti-condensation.
  • Insulation of metal roofs, ancillary structures, collectors, garages.
  • Protection of window and door openings.
  • Processing of freezing floors, basements, ceilings.

Benefits of liquid insulation

  • Possibility of application to the substrate of any configuration, as well as the treatment of hard-to-reach places.
  • Minimum thermal conductivity. Partly due to the porosity of the structure.
  • Up to 100 m2 of surface can be processed in 1 day.
  • High resistance to mechanical damage.
  • Reduction of heat consumption by 25-30%.
  • Insulation does not change appearance facade, so there is no need to coordinate work with technical supervision.
  • There is no need for complex preparation of the base (it is enough to clean the surface from dust).
  • Refractoriness.
  • The total cost of work on thermal insulation in comparison with the use of panel and roll materials is 30-40% lower.

According to its thermal qualities, a liquid insulation for walls with a thickness of 1 mm is equivalent to a block insulation (sheet foam, glass wool, mineral wool) with a thickness of 5-7 cm.

The disadvantages of using liquid insulation include:

  • short shelf life,
  • sensitivity to transportation conditions,
  • relatively high cost,
  • the absence of specific methods for calculating the indicators of thermal conductivity of the material, and, therefore, a possible increase in the consumption of heat paint, in comparison with the data specified in the instructions.

Types of liquid insulation

The most popular types of liquid insulation today are:

Liquid ceramic thermal insulation is similar in structure to a suspension and is intended for application on wooden, brick concrete bases, in addition, it can be used for metal, plastic and plasterboard surfaces in order to increase their rigidity and provide protection against mechanical damage.

The advantages of ceramic liquid insulation include safety for human health, fire resistance, water resistance, water resistance. On top of this composition, you can use any type of finish - wallpapering, plastering, painting. This will not affect the thermal insulation qualities of the material in any way.

The basis of liquid insulation is varnish or water, so their application is best done in the warm season (at temperatures above + 7 ° C). If it is necessary to treat the surface in the winter season, it is better to give preference to lacquer-based compositions.

In the process of application, the composition should be stirred every 10 minutes, this will exclude delamination of its structure.

The base on which the liquid insulation will be applied must first be cleaned of contamination (dust, dirt, rust), and then degreased (if metal processing is to be done).

For applying thermal insulation, it is better to use a foam roller or a wide brush.

To ensure the maximum insulating effect, the composition is applied in several layers, the thickness of each of which is no more than 0.5 mm. Each subsequent layer should be applied at intervals of at least a day after the previous layer has dried.

This material is the second most popular among liquid wall insulation. According to its characteristics, it surpasses mineral wool and expanded polystyrene. Foamed and hardened carbide resin is used as the basis of the composition, which significantly reduces the cost of the final product. Liquid penoizol is 2 times cheaper than ceramic thermal insulation. This material has been used for a long time (since the 30s of the last century), however, due to its high cost, it was previously low in popularity. Today, thanks to the introduction of the latest technologies in its production, it has become more affordable. Moreover, it can be produced directly at the construction site.

Most often, penoizol is used as a "jellied" insulation between the inner and outer frame walls of the building, however, if necessary, it can be placed on a sheer wall, with a sufficiently large layer.

The indisputable advantages of liquid penoizol include high reliability, fire resistance, endurance and durability (about 50 years). Thermal insulation is applied quite simply. After the surface has been cleaned of dust, the foam is poured under pressure, after which it is dried.

  • Liquid (jellied) foam

In terms of popularity, this liquid insulation for walls is in third place. High insulating qualities, environmental friendliness, the possibility of pouring into the most inaccessible places and high strength perfectly explain this fact. Injected foam has a cellular structure, odorless, which makes it possible to use it for external and internal insulation. The high strength of the material allows it to be used in the insulation of high-rise buildings. In addition, the composition can be produced directly at the construction site.

Liquid foam is highly resistant to damage caused by microorganisms and fungi, and is durable. The porous structure of the material allows the walls to breathe. Injected foam can be used over a wide temperature range. The service life is 60-70 years. The pouring technology of this material is identical to the application of liquid penoizol.

The most common brands of liquid insulation

  • Corundum. It is a sales leader with high quality and corresponding price. Main feature material is the ability to apply an ultra-thin layer (less than 1 mm) with high resistance to external influences and excellent adhesion.

  • Akterm (water-based - Standard, vapor-permeable nitro-based - Nord, for brick and wooden walls - Facade, for metal - Antikor). It is characterized by high thermal efficiency. In terms of the degree of thermal protection, 1 mm of material is comparable to 5 cm of mineral wool. This type of liquid insulation can be used at a temperature of -60 ° - + 600 ° C.
  • Teplomett. In terms of thermal insulation effect, 1 mm of material corresponds to 2.5 cm of expanded polystyrene, can be used at low temperatures (down to -20 ° C), environmentally friendly, easy to tint.

  • Astratek. It has a fine-pored structure, it is environmentally friendly and has an anti-corrosion effect. The service life reaches 30 years.

Nowadays, thanks to new technologies, more and more various modern insulation materials with improved characteristics appear. Liquid thermal insulation for walls is one of the relatively new developments that will significantly speed up and facilitate the process of wall insulation both outside and inside the building.

Comfort in an apartment or house directly depends on normal temperature indoors, therefore, the overwhelming majority of home and apartment owners are thinking about wall insulation today. Modern technologies make it possible to provide external thermal insulation of the surfaces of the house, even if the apartment is located on one of the upper floors - for this, not only heaters in the form of slabs or mats are used, but also liquid compositions that are easier to work with.

As a result of carrying out such thermal insulation works outside the building, the generated heat will be stored inside it, preventing the premises from cooling down in winter and even overheating - on hot summer days. In addition, liquid insulation is able to protect walls from moisture penetration and temperature extremes, thereby preventing erosion of building materials, the appearance of condensation and mold colonies on the bearing walls.

What can be attributed to liquid insulation?

Today on the market you can find several types of liquid insulation made on the basis of various materials and differing in application technology.

  • liquid ceramics;
  • liquid expanded polystyrene or penoizol;
  • sprayed ecowool.

Each of the materials has its own characteristics, its own "pluses" and "minuses", differences in the field of application. What unites these heaters is the ease of application to the surface, which does not take much time. So, using such materials, it is quite possible to carry out the process of thermal insulation of even large areas in just one day.

You may be interested in information about which one is suitable

Unfortunately, not all liquid heat insulators can be applied without the use of special equipment. In this regard, it will be necessary to invite for the work of specialists who have the technological skills of performing work, and who have special installations for applying liquid material.

Before applying any of these thermal insulation compounds, the surface of the walls must be prepared by removing dirt and dust deposits, etc. if necessary, making repairs in the form of sealing cracks, protrusions and depressions. However, for some types of liquid insulation, surfaces do not need to be repaired, since the applied materials themselves are able to close or fill all existing cracks, gaps at the joints of building structures and other surface flaws that appeared, for example, when a building shrinks. But in any case, the cleaned and prepared walls will have better adhesion to the liquid insulation material, which will increase the quality of thermal insulation and reduce heating costs.

To understand what the different types of such liquid heaters are, and what are the features of their application, each of them should be considered in more detail.

Liquid ceramic wall insulation

Ceramic liquid insulation material in appearance practically does not differ from thick acrylic paint. Nowadays, there are several compositions on the building materials market that have different names, but approximately the same structure and consistency:

  • The bonding base of the compositions of ceramic liquid thermal insulation is a water-acrylic mixture that promotes the adhesion of the insulation to the wall and the uniform distribution of thermal insulating components on its surface.
  • Additional components are introduced into the water-acrylic mixture, which improve the quality and performance of the heat insulator. Most often, such additives are natural and artificial rubbers, silicone, and similar materials, which give the composition elasticity and water resistance.
  • Ceramic granules are the main component that helps to reduce heat loss of the insulated surface. The granules are microscopic in size and ideally spherical, filled with highly discharged air (gas), which provides high thermal insulation and makes it possible to distribute the mixture over the wall surface in a thin layer. Ceramic granules make up 80% of the total volume of the thermal insulation material, so its consistency resembles a thick dough or paste.

A high-quality ceramic liquid thermal insulation material is one in which, after complete polymerization, the percentage of voids in the layer applied to the surface will be 75-80%, which allows you to create between the wall surface and the outer surface applied insulation ultra-thin layer with very high resistance to heat transfer.

It should be noted that the proportions of the components of this material are, in principle, approximately the same, regardless of its manufacturer, brand and name. The difference can only be in the quality of the raw materials used and the technology for making the mixture.

Popular liquid ceramic heat insulators

Today, many different ceramic liquid heaters are produced for thermal insulation of walls and other building structures, and several of them have gained the most popularity and are used most often.

These heaters are subdivided into brands depending on the purposes, conditions of application and subsequent operation, from the materials of the surfaces for which they are intended. For example, some of them can be applied only at positive, and others at negative ambient temperatures. There are materials designed for insulating metal structures, even those covered with a layer of corrosion, or for thermal insulation of brick or concrete walls.

Typically, such a heat insulator is applied in several layers, the thickness of each of which can be from 0.4 to 1.0 mm, and requires drying within a day.

The most popular are the following formulations:

"Astratek"

This liquid insulation composition, produced by the Russian company "Astratek", has the consistency of a homogeneous suspension, so it can be applied not only with a brush, but also by spraying using spray guns. The heat insulator of this brand is produced for different surfaces - it is "Facade", "Metal", "Anti-condensate", "Universal".

Liquid thermal insulation coating "Astratek"

"Astratek" can be used for thermal insulation of surfaces that warm up during operation to a temperature of 150 degrees, and the elements coated with this composition are able to withstand thermal drops from -60 to +250 degrees. Insulation can be applied in several layers, each of which should be no more than 0.4 mm thick. The total coating thickness is usually at least 3 mm.

"Corundum"

Korund is another brand of heat-insulating liquid materials produced by another Russian manufacturer, which gives a 15-year guarantee for the operation of such coatings.

Liquid thermal insulation compounds of the Korund brand

The heat insulator is a fairly dense homogeneous mass with a high degree of adhesion to any building materials such as concrete, metal, brick, plastic, glass and others.

Preparation of the "Korund" composition for application

The application of this material is done with a brush, spatula or spray gun. If the solution will be sprayed on the surface of the walls, then it should be diluted with plain water. The liquid is poured into the mass in small portions, and then the solution is mixed using a construction mixer.

Corundum is also subdivided into solutions designed for a specific area of ​​construction and various conditions of use. So, the mixtures "Facade", "Classic", "Winter", "Fire protection", "Lotos" and "Antikor" are produced.

  • "Korund-Facade", as its name implies, is used for thermal insulation work on the outer surface of walls made of various materials. The solution can be applied to prepared walls with a layer of 1 mm, at a surface temperature of + 5 to +145 degrees. This heat insulator may well be used as a basis for further finishing.

Thermal insulating paint "Korund" on the facade of a multi-storey panel building

  • "Korund-Classic" applied with a layer thickness of 0.5 mm, and can be applied at surface temperatures from -60 to 250 degrees. The solution is able to eliminate freezing of walls, the appearance of fungal formations, and prevent the formation of condensation. The material gives high protection to surfaces from heat loss, while maintaining normal air and moisture exchange, that is, the walls remain "breathing".

The composition can also be used to insulate wooden walls - it has sufficient vapor permeability

  • "Korund-Winter"- this composition is intended for work carried out at an air temperature of -10 to -60 degrees. The solution is used for the external surfaces of various buildings erected in regions with a harsh climate.
  • "Korund-Antikor"- this heat insulator is supplemented with anti-corrosion properties, and it is permissible to apply it, including on surfaces covered with a rusty coating. It is perfect for insulating walls and gates of a garage or other metal buildings. The convenience of using this solution is that it can be applied to an unprepared and uncleaned surface.
  • "Korund-Fire protection"- such a heat-insulating material consists of three layers - primer, fire-retardant and finishing protective and decorative. The solution has high adhesion to surfaces, and upon drying it acquires high strength and the ability to withstand the destructive effects of an open flame.
  • "Corundum-Lotus"- the composition is used as a covering layer for insulation of the Korund-Fasad brand. It has water and dirt repellent properties, which allows you to keep the facade clean and original for a long time. This material is often chosen for the treatment of the walls of multi-storey buildings.

Some thermal insulation materials in the "Korund" line have additional properties:

  • "Corundum-Waterproofing" proved to be excellent in protecting interpanel seams from moisture penetration.
  • "Korund-Sanitary" used for the treatment of internal surfaces of walls and floors in kitchens, bathrooms, basements, balconies and loggias as reverse waterproofing.
  • "Korund-Foundation" intended for complex waterproofing and insulation of horizontal and vertical surfaces of foundations
"Armor"

Insulation composition "Bronya" is a proprietary development of the Vologda LLC "Innovative Resource Center". It is also made using a ceramic material, but the manufacturer presents it as superior in its thermophysical properties to all the analogs already described above.

Another liquid insulation of domestic production - "Bronya"

"Bronya" by its consistency resembles a thick paint, has high adhesion, heat-insulating and anti-corrosion qualities. This material is also divided into several types, designed to isolate specific areas of the building, or they can be universal. Their area of ​​application can be recognized by their names. With the help of the Bronya liquid heat insulator, it is possible to impart special insulating qualities to the following surfaces:

- Roofs made of any material.

- Facade walls of residential, public and industrial buildings

- Internal load-bearing walls and partitions.

- External and internal slopes of windows and doors.

Indoor floors, as well as on verandas or terraces.

- Pipelines of cold and hot water supply, gas mains and heating mains located in heated and unheated premises, as well as outdoors or underground.

- Ventilation and cooling systems.

- Metal constructions.

The heat-insulating liquid material "Bronya" can be divided into the following varieties - these are "Classic", "Universal", "Standard", "Facade", "Wall", "Light", "Antikor", "Metal", "Fire protection", " Winter "," Nord "and" Volcano ". Moreover, each of them is produced in two versions related to the flammability group G1 or NG, that is, to the category of non-combustible materials.

In addition to these basic thermal insulation materials, a line of primers is produced, designed for work on the preparation of various surfaces and for different operating conditions.

Another series of Bronya compounds are water-repellent and waterproofing coatings made on a polymer basis.

Thermal insulation material is applied to walls, as a rule, with a thickness of 1 mm, and is capable of operating in a wide range of operating temperatures - from -60 to +200 degrees.

Positive and negative qualities of liquid ceramic insulation compositions

Liquid ceramic insulation has a number of advantages over other insulation materials:

  • A layer of high-quality liquid thermal insulation of 1 mm is equal in its thermal characteristics to a 50 ÷ 70 mm layer of mineral wool.
  • The thermal insulation coating turns out to be almost seamless, which, in principle, cannot be achieved with other types of insulation materials.

  • Insulation compositions intended for internal work are environmentally friendly and absolutely safe for human or animal health.
  • When insulating country houses, which are left unattended in winter, this insulation, in principle, cannot be dismantled and stolen by intruders.
  • Unlike some board materials, liquid insulation is not a source of dust spread, which is especially valuable for people prone to allergies.
  • The simplicity of the application technology, similar to conventional painting, does not require the use of additional equipment or the invitation of specialists.
  • Ultra-thin application, especially on the inside of walls, can significantly save usable space.
  • Liquid thermal insulation reliably resists fungal and mold growth, as well as insect nesting.
  • The long service life of this kind without repair and other unforeseen troubles, for example, severe pollution, swelling from excess moisture, attacks by rodents, makes this type of thermal insulation an excellent choice for insulating a private house.

Such materials have practically no drawbacks. The only thing that can upset the buyer is the poor quality of the purchased composition of an unknown manufacturer, so the choice must be taken very seriously.

Selection of liquid ceramic insulation

In order to choose a quality material intended for a specific area of ​​construction, where it will be used, it is worth carefully studying the characteristics of the composition, which are necessarily located on the packaging or in the accompanying documentation.

Despite the fact that a liquid heat insulator has a rather high price, you should not experiment and immediately purchase the one that is cheaper, in the hope that it will also be able to perform the necessary functions, even if they are not indicated in the instructions.

When purchasing insulation, you need to pay attention to the following points:

  • The density of the mixture. The material is considered to be of high quality if 1 liter is equal to no more than 0.6 kg - so, a ten-liter bucket should not have a net weight of more than 6 ÷ 6.5 kg. If the mass exceeds the specified norm or is much less than it, then this will be the reason to doubt the heat-insulating properties of the acquired composition.
  • When buying such a heat insulator, you need to view the bucket through the light and see the stratification of its contents, since the lighter ceramic fraction rises upward. The thicker the top layer, the higher the thermal insulation effect.
  • The structural structure of the mixture is also important - ceramic microgranules should be felt in it in the form of roughness. To determine their presence, a small amount of mass is taken on the fingertips and rubbed. If there are no roughnesses, then you should choose a heat insulator of a different brand, or purchase it from a more conscientious seller.
  • You also need to pay attention to the color of the mixture, since it should be completely white. If there is a grayish or yellow tint, then this indicates a violation technological process manufacturing, and it is not known how this material will behave both during its application and during operation. However, of course, it is necessary to take into account the fact that some formulations have already introduced a color pigment, which should be mentioned in the characteristics of the material applied to its packaging. In this case, the color must correspond to the declared characteristics.

Tips for applying liquid ceramic insulation to a surface

Liquid insulation can be easily applied to any surface, so the work can be done independently, adhering to some recommendations:

  • So that the wall after covering it with a heat insulator is even, it is recommended to treat its surface with a grinder, with a brush installed on it, which will clean the protrusions remaining after the mortar used for masonry has dried.
  • When applying the compounds to surfaces made of ferrous metal, they should be dust-free and degreased. If the heat insulator is applied to non-ferrous metal, then it is necessary to remove the gloss from it and apply a primer to it.
  • Mixing the mass of liquid insulation is carried out immediately before applying it to the wall. This process is carried out using a mixer attachment installed on an electric drill. The mixing time is 6 to 10 minutes.
  • Some formulations with a thicker consistency are diluted with water. The mass is diluted to the desired consistency, depending on the method and area of ​​application of the material. Dilution ratios are usually indicated on the packaging.
  • Liquid insulation is applied in layers, and the layers should not be more than 1 mm - this parameter depends on the brand of the composition. Each of the layers must be completely dry, and this process takes at least 24 hours.

Liquid ceramic insulation is a relatively new technology that has not yet gained widespread popularity, perhaps simply due to a lack of awareness among homeowners. Nevertheless, it has excellent thermal performance and can be successfully used in various areas of private construction. With the right choice of insulation and adherence to the technology of its application, you can get the expected result of a significant reduction in the heat loss of the building, which will save you from numerous troubles for many years.

Liquid expanded polystyrene

Liquid expanded polystyrene has many names - they are given to it by the manufacturers themselves: it can be, for example, "unipol" or "mettemplast", but its most familiar and popular name is "penoizol".

Insulation of the attic walls with "penoizol"

The composition of these materials, in general, is identical and is a modified polystyrene foam.

Unlike conventional expanded polystyrene (foam), "penoizol" has a number of improved characteristics, which are especially important for use in residential buildings - this is its low flammability and low content of harmful components. Using "penoizol" and applying the recommended technology of its application, you can significantly speed up and reduce the cost of the process of building a house.

Components, manufacture and application of "penoizol"

  • For the manufacture of this liquid insulation material, urea-formaldehyde resin is used, intended for cold hardening foams, a foaming agent, orthophosphoric acid and water. Depending on what density of insulation is needed, the consumption of resin added to the composition varies.
  • The constituent components are mixed in a mixer of a special gas-liquid apparatus (GZHU) using compressed air, which helps turn all the ingredients into a composition that, when applied to surfaces, turns into a lush and dense foam.

For spraying "penoizol" special equipment is required

Sprayed "penoizol", blown out of a special spray gun under the pressure of air, tightly fills all cracks and cracks on the wall surface, forming a sealed seamless coating. The foam sprayed on the walls is white with a slightly yellow tint. It lays down on the surface in a thin layer, and then begins to expand, filling all the space available to it. Spraying is usually done between the timber frame posts. or between the rafters, if the roof is insulated.

  • The sprayed and expanded mass of foam sets after 10-15 minutes, and hardens after 3-4.5 hours. The coating gains its final strength in two to three days, after the layers have completely dried out, and at the same time "penoizol" acquires all its thermal insulation qualities.

  • Installation of this insulation is carried out in one day, which is three to four times faster than laying thermal insulation material in mats or slabs. In addition, “penoizol” does not require additional auxiliary materials, such as a vapor barrier and windproof membrane, since it itself performs their functions.

The digital characteristics themselves say a lot, but some of them are worth considering in more detail:

  • Thermal conductivity. This parameter is very low, therefore, for wall insulation, 80-100 mm of this heat insulator is enough to significantly reduce heat loss at home. This quality of the material will help to make the heating system of the house much more economical, which compensates for the cost of insulating the house for one or two winters.

The thickness of the heat insulator layer is selected depending on the winter temperatures of the region where the insulation will be carried out, and on the design features of the wall.

  • Flammability. "Penoizol" belongs to rather safe groups: flammability - G-1, flammability - V-2, smoke formation - D-1, toxicity of combustion products - T-1.
  • Chemical and biological resistance of the heat insulator. Fungus and mold do not form on "penoizol", as it is a breathable material that does not retain moisture on its surface and inside the layers. Rodents do not touch it, and insects do not start inside the insulation. The material does not react in any way to an aggressive environment and most organic solvents.
  • Adhesion. In the liquid state, "penoizol" is sufficiently adhesive to almost "grow together" with the surface on which it is sprayed, as it penetrates into all the depressions and irregularities of any material.
  • The durability of the insulation is guaranteed by the manufacturer - the terms from 35 to 50 years are declared. Such a duration of operation was justified experimentally in laboratory conditions, with the help of artificial creation of various multiple adverse effects on the material.

Disadvantages of "penoizol"

This liquid insulation also has its own negative qualities, or rather, one thing, but it is it that stops many buyers - these are the toxic substances that are part of "penoizol".

It cannot be said that "penoizol" is an absolutely environmentally friendly material, since it contains formaldehydes. It is they who, during application and polymerization, emit a certain amount of gases that have bad smell... And, of course, these substances cannot be called useful in any way. However, here it will be appropriate to recall that all non-water-based paints and varnishes do not exude very pleasant odors, and after drying and weathering, not a trace remains of it. So it is with "penoizol" - after the process of its hardening is completed, the unpleasant "aroma" will also disappear.

Moreover, if you believe the manufacturers, the released harmful substances have an extremely low concentration. This is also confirmed by the hygienic certificate for a similar material. Nevertheless, the choice of a heat insulator remains with the owner of the house to be insulated, especially since there is also a natural liquid insulation on the building materials market - this is ecowool, which will be discussed below.

Ecowool

Ecowool is a natural thermal insulation material used to insulate various surfaces of a house, including walls. It should be noted right away that this heat insulator cannot be unambiguously called liquid, but it can be the main component for a mixture applied in a liquid state.

Ecowool manufacturing materials

Ecowool is made from fluffed cellulose fibers treated with antiseptics and fire retardants, that is, to make it clearer - these are wood and minerals. And unlike other insulation materials, ecowool has not a porous, but a capillary structure.

To be more precise, several types of raw materials are used for the production of this insulation:

  • Typographical marriage left over from the printing of magazines and books.
  • Waste from the manufacture of corrugated and ordinary packaging cardboard.
  • Secondary raw materials, that is, waste paper - old books, newspapers, magazines and the like. This type of raw material is considered second-rate, since it has significant contamination and consists of various materials, so the fibers are heterogeneous.
  • Waste from the pulp industry.

So, ecowool is 80% shredded cellulose fiber, 12% of the total volume is boric acid acting as an antiseptic. This substance resists the formation of mold and mildew in high humidity. Sodium tetraborate, a fire retardant, is 8% ecowool - it is designed to increase fire resistance and add insecticidal qualities to the mass that will resist the appearance of nests of various insects.

Ecowool fibers become sticky after they are wetted, due to the lignin contained in them - this is a natural substance contained in plant cells.

This composition is increasingly used to insulate not only residential buildings, but also industrial premises.

Methods for laying insulation based on ecowool

Warming with this material is carried out in different ways:

  • Dry method, when ecowool is laid in bulk. This technology is only suitable for horizontal surfaces.

  • Laying or installing ecowool pressed in the form of slabs - this method can also be called dry, but it is applicable to both horizontal and vertical surfaces.
  • Wet way. In this case, dry crushed cellulose fibers are mixed with water, and then, using a special installation, the resulting mixture is sprayed onto the surface. This can be used to insulate floors and walls, as well as the roof from the inside.

The mechanism of adhesion of materials in this method is based on the fact that when wet in cellulose, natural glue - lignin is activated, and when the composition is blown out under the pressure of air from the pipe, the mixture easily adheres to the surface of the walls, clogging all the gaps and joints. When dry, the composition forms a dense, seamless cover on the wall.

Ecowool spraying using "wet" technology

  • The wet-glue method differs from the previous one in that cellulose is mixed not only with water, but also with glue. The glue component is added to increase the adhesive qualities of the composition, therefore the adhesion of the eco-insulation to the surface increases several times. The adhesive composition is most often used for insulation work, since it is more reliable than cellulose mixed only with water. PVA glue and similar compositions are used as an adhesive additive. They are diluted in certain proportions with water, and then added to the cellulose mixture.

Equipment for applying ecowool

For spraying, a factory-made apparatus or a home-made version of it can be used.

  • All devices for laying thermal insulation of their liquid ecowool work according to the same principle and have approximately the same configuration:
  • The installation should have a receiving hopper for placing shredded cellulose. In homemade models, its role is successfully played by a plastic barrel, which is not difficult to find in hardware stores.

  • Turner. In a homemade installation, an electric drill with a mixer attachment is used as it. This element is needed in order to fluff the pulp from the compressed state in which it is in the package.
  • The pump that is necessary for efficient and fast running of the liquefied ecowool through the hoses. In home-made versions, different models of vacuum cleaners with a blowing function are often used for installation.
  • Corrugated flexible pipes with a diameter of 50 ÷ 80 mm are used as inlet and outlet hoses when spraying material on the surface.
  • There are specialized kits for applying wet cellulose, consisting of a pump, hoses and nozzles.

Ecowool performance characteristics

  • Thermal conductivity. Ecowool, with a high-quality application to the walls, perfectly retains heat inside the building. The thermal conductivity coefficient is only 0.032 ÷ 0.041 W / m × ˚С, and it can quite be called one of the lowest among the most frequently used insulation materials.

Due to the fact that the material sprayed on the surface forms a continuous layer without seams, the occurrence of cold bridges is excluded. Ecowool is lightweight, it is usually applied to walls with a not very thick layer of no more than 100 mm, but it creates excellent insulation for the house. This is due to the naturalness of the insulation, which consists mainly of wood fibers with a capillary structural structure that can hold large volumes of immobilized air inside.

  • Soundproofing. Ecowool is an excellent sound absorber. So, its layer of only 100 mm can reduce noise by 60 decibels. This is also due to the fact that the wall covering turns out to be continuous, without seams, since noise waves easily penetrate through the same "bridges" that arise at the joints of the slab insulation.
  • Environmentally friendly insulation. The composition of ecowool was described above, and from this it is clear that the insulation is made from natural materials that do not emit substances harmful to humans.
  • Fire resistance. The liquid composition of ecowool contains fire retardants, which increase the fire resistance of the material. But since it consists mainly of cellulose, it is still impossible to achieve complete fire safety, and it is assigned a flammability group G2 (GOST 30244).

However, one must pay tribute to the composition of ecowool - it tends to self-extinguish, and also does not emit toxic substances when smoldering.

Fire retardants contribute to the fact that when the insulation burns, a minimum amount of toxic substances is released. Basically, it is carbon, which does not pose a strong threat to human health.

In the event of fire, during the thermal decomposition of the insulation, water is abundantly released from its structure, which slows down the spread of fire, transferring it to decay, and then to extinction.

  • Adhesion. Cellulose mixed with water and glue has high adhesion to almost any building material.
  • Density. Fluff pulp, moistened with glue and water, when applied to a surface and dries, creates a layer that has sufficient density to create an air gap between the fibers, which is part of the thermal insulation. The density of ecowool largely depends on the method of its application. So, when laying the wet composition on vertical surfaces, the density is approximately 55 ÷ 65 kg / m³.
  • Moisture resistance. Ecowool cannot be called a moisture resistant material - it is capable of absorbing up to 30% moisture from the total mass. But since this insulation is "breathable", the moisture that it absorbs does not stay inside the layers. When dry, ecowool does not lose its original insulation qualities.

Disadvantages of ecowool

This natural insulation also has its drawbacks, which it would also be nice to know about:

  • Ecowool shrinks over time, giving a decrease of about 10% of the original volume. Therefore, when laying it, it is recommended to apply a layer slightly thicker than planned to the wall.
  • The ecowool layer should not be covered with vapor-proof materials, since it must be able to be ventilated, otherwise it will quickly lose its thermal insulation qualities due to increased internal humidity.
  • In order for such a heater to function for a long time and with the required efficiency, it is necessary to carry out a high-quality installation, in compliance with all technological standards, which can only be done by a qualified master - and this will lead to additional costs.

The choice of insulation is up to the homeowner. But in any case, when purchasing the material you like, you need to carefully study its technical and operational characteristics and instructions for applying to a particular surface. study the link.

held a presentation of liquid thermal insulation Korund

At the OSM exhibition

Liquid thermal insulation is gaining more and more popularity in the energy saving market. The issue of competition with Western liquid heaters is becoming more and more relevant. This is due to the fact that during the Soviet Union the priority was for cheap energy and the issue of energy conservation was not as acute as it is today. In the last 10-15 years, our state has paid attention to energy conservation, since energy prices have risen sharply, it is necessary to develop the latest heaters.

Our company has developed liquid thermal insulation, which is competitive with Western counterparts. Of great interest is liquid thermal insulation, which is made on the basis of vacuum glass balls and a polymer binder. Liquid insulation attracts with its simplicity of manufacture, has low material costs for manufacture and ease of application to various types of surfaces. A wide range of applications for liquid thermal insulation. Of particular interest for thermal insulation materials is liquid thermal insulation based on vacuum glass balls filled with vacuum on a polymer binder. Liquid insulation is used for insulating building facades, roofs, water pipe insulation, heating networks.

We present liquid thermal insulation Korund. Corundum has established itself as the best liquid insulation of the 21st century. Corundum is used for household needs - it is freezing of floors, ceilings, internal and external walls. Thermal insulation of cold bridges is of great importance: window slopes, insulation of interpanel seams, insulation of balconies and loggias. It is also used for insulating cottages - facades, walls, water supply networks and sewerage systems. Liquid thermal insulation Korund is used on an industrial scale in such industry giants as Gazprom, LUKOIL, TGK. Housing and communal sector. Especially we will not replace Corundum when restoring buildings.

A number of tests were carried out, and conclusions were obtained on the use of Liquid insulation Corundum, see the conclusions:

You can also see the reviews of industrial enterprises:

Ultimate safety on hot surfaces.

Application on the surface of Liquid thermal insulation.

For many years, the industry worked with burn protection guidelines that could not take into account thermal diffusivity and thermal conductivity - the properties that ultra-thin thermal insulation coatings have. The generally accepted maximum surface temperature was 60C.

The problem was that we were initially dealing with the maximum allowable temperature on the surface, while physical characteristics material was not taken into account.

Real experience with thermal insulation coating liquid thermal insulation showed that its characteristics for protection from burns are far superior to those accepted in the industry.

For example, on a surface with a maximum temperature of 60 ° C, the surface

Liquid insulation is simply warm to the touch and does not burn like a metal surface at this temperature.

This phenomenon is explained by low thermal conductivity and thermal conductivity. Liquid insulation which in turn makes it safer and reduces the likelihood of burns for humans even at much higher temperatures.

Two different studies were carried out using liquid thermal insulation to determine the "safe" surface temperatures, determined by mathematical calculations and the contact method. “Standard practice for determining the contact temperature of heated surfaces (calculation method)

The calculation method determines the values ​​of heat fluxes and temperatures on the surface, measured after contact with a steel surface covered with liquid thermal insulation Corundum ... Calculations show changes in contact temperature, since it depends on the thermophysical properties of the surface with which the skin is in contact.

The calculation results for liquid thermal insulation are shown in Table 1.

Safety regulations define a “safe” or “acceptable” temperature for heated surfaces. They determine the effect on the skin of temperature = 60 ° C, within 2 seconds when it comes into contact with the surface. This will result in a medium-sized first degree burn.

Table 1 shows that the “safe” contact temperature, when exposed for 2 seconds, is about 60C, which is the upper limit above which the skin tissue will be damaged, and this will already be a second degree burn.

Table 1 below shows the thickness of liquid insulation Corundum , which is necessary to reduce the temperatures of various steel surfaces to a given "safe" level.

In these calculations physical properties the heated surface was taken over steel.

Liquid insulation.

1. Problem - Formation of ice and icicles on the roofs of buildings.

Pitched roofs.

Reasons - The metal flooring of the pitched roof is constantly heated from the abundant heat release from the attic floors and pipelines, the hanging cornices are heated due to the ascending flows from the heat release from the facade.

The boundary layer of snow melts from a warm roof, plus a cornice heated from below - all conditions for the appearance of ice and icicles.

Those who consider the sun to be guilty are mistaken. In the winter of 2010, there were frosts in Moscow, heavy snowfalls, there was practically no sun, but the icicles grew successfully ?!

Solution - It is necessary to fight not with icicles, but with the reasons that cause them.

Attic spaces need to be brought in line with modern requirements, i.e. the attic must be cold (restore natural ventilation), the heat dissipation of the attic floor must comply with the requirements of SNiP. It is necessary to check the condition of the insulating layer of the attic floor and bring it to the norms of SNiP, by means of additional insulation.

Heating system pipelines, flanges, valves, in attic spaces, insulate with Liquid thermal insulation, with a layer of 1.2 mm. (3 layers).

On the eaves of the roof (up to the front side of the facade) apply a coating of liquid thermal insulation, with a layer of 1.2 mm (3 layers), from the bottom of the eaves - to the front line of the facade, on top of the eaves, with a width of 0.5 - 1.5 m.

The inner surfaces of the funnels of gutters and downpipes should be treated with a coating of liquid insulation, with a layer of 1.0 mm, to a height of 1.0 - 1.5 m. All these measures allow you to leave the roofing in the "cold" zone, there is no heating - there are no conditions for snow melting ... Snow has been dropped from roofs at all times and nowadays it must be done periodically - there is no alternative!

Result - A dramatic reduction in heat losses in the attic space and natural ventilation. Roof decking, cornices and gutters are isolated from the outside air - the causes of icicle formation have been eliminated.

Note - Work on the application of Liquid thermal insulation is of a paint type, not laborious, and does not require large capital expenditures. Productivity of work, when applying a coating of liquid thermal insulation in one layer (0.5 mm), airless spray - 100 m2 / hour, brushing - 0.1 hour / m2.

The method was implemented in 2011 on the roof attic of the State Hermitage Scientific Library, with the aim of eliminating condensation and ice formation, and will be applied to the ceilings above three Hermitage halls in 2013.

The cost of the material is 452 r / l (1 layer - 0.5 mm, liquid), consumption - 0.8 l / sl. (362 r / sl.) Work is carried out from towers, or by the forces of industrial climbers (applies to cornices). Production of works - insulation of attics and pipelines - all year round, cornices and gutters - in the warm season. The durability of the coating of liquid thermal insulation is 15 years or more.

Mansard roofs.

The reasons are insufficient insulation from the side of the residential area, increased heat loss and ascending flows from the facade cause heating of the roof deck.

Solution - Option 1 (existing buildings) - From above, over the entire area of ​​the roofing, apply liquid thermal insulation Korund, with a layer of 1.0-1.2 mm. Eaves, from below, treat with liquid thermal insulation, with a layer of 1.0 mm, up to the front line of the facade. To process the inner surfaces of the funnels of gutters and downspouts, with a layer of 1.0 mm by 1.0-1.5 m.

Option 2. (buildings under construction) - In order to protect against condensation, the inner surfaces of the roofing should be treated with a coating of liquid thermal insulation Corundum, a layer

1.0 mm. To reduce convective currents, reduce the air gap between the roofing deck and the inner cladding to a minimum (increasing the volume of rooms), treat the outer surfaces of the cladding (before installation) with a coating of liquid thermal insulation with a layer of 1.2 mm. The outer surfaces of the roof, gutters (for protection against ice, solar radiation, UV and rain noise) should be treated with a coating of Corundum insulation, a layer of 0.8-1.0 mm (2 layers), other "traditional" insulation materials are NOT NECESSARY!

Result - Additional insulation of the roof in winter (85% of the heat flow is reflected back into the room) - 35% reduction in heating costs. In summer - 100% protection from rain and hail noise, solar radiation and UV in summer - it is cool in the premises, air conditioning costs are reduced).

Additional insulation of the roof with liquid thermal insulation allows you to eliminate the heating of the flooring - the causes of icicle formation have been eliminated.

Flat roofs.

As a rule, there are no problems with the formation of icicles on flat roofs, because they have a fencing parapet and are made over warm attics or technical floors (usually adapted for housing) and must have serious insulation.

Problem - Mostly insufficient insulation of the roof overlap and extremely low durability of the elements of the roof covering, which necessitates endless and frequent repairs.

This happens because water vapor accumulates in the layer of mineral wool insulation, negative temperatures cause the formation of ice microcrystals that destroy the bonds in the insulation.

As a result, the insulation loses its properties, the resistance to heat transfer drops, freezing of ceilings, mold and fungus appear on the inner surfaces. In summer, ultraviolet streams destroy the integrity of the upper layer of the "pie" of the roof, water gets into the insulation, and next winter the process of destruction of the roof occurs in a power-law progression.

The process of local and complete destruction of such roofs takes 3-4 years.

Nobody is trying to eliminate the reasons for the destruction of such roofs, but simply make "patch" repairs and after a couple of years everything starts again, and again the "long-suffering" budget loses millions of rubles.

Solution - The easiest and cheapest way.

In the summer, carry out a "patch" repair of the integrity of the upper layer roofing... Depending on the condition of the insulation (inspection is necessary), apply the required number of layers of liquid thermal insulation (determined by calculation) to the top layer of the roof and treat the inner surfaces of the gutters with Corundum insulation.

More expensive and time consuming method.

Complete removal of roofing, pouring a cement-sand screed along a reinforcing mesh with the creation of slopes, for water drainage and applying the required number of layers of liquid thermal insulation (determined by calculation) with the treatment of gutters.

One millimeter of a coating of liquid thermal insulation corresponds to 50 mm in terms of thermophysical characteristics. mineral wool insulation.

The result is 100% UV and 85% solar energy is reflected back into the atmosphere.

The top layer is protected from UV and moisture. The roof deck does not heat up

in summer and does not freeze in winter, the destruction of the insulation is stopped (or excluded). Gutters treated with liquid insulation do not freeze.

2. Problem - Facades of the city of Moscow, Sevastopol, Astrakhan, Arkhangelsk, etc.

Facades of the historical part of the city.

Problem - The need to periodically repair the same façade is sometimes overwhelming. Apparently, the funds allocated for repairs are not large, hence the quality of materials and work is corresponding. After 4-5 years, decorative ornaments are destroyed, paint peels off - the facades have an untidy appearance, after a couple of years, repairs are underway again.

Solution - After the restoration work, the facade is treated with acrylic primer, deep penetration. The coating of liquid thermal insulation is applied to the facade with a layer of 0.8-1.2 mm. or facade paints are applied on top.

Result - The coating of liquid thermal insulation Corundum fits with a continuous, seamless membrane surfaces of any geometric shapes (sculptural compositions, decor, etc.), the slopes of window and door openings.

The coating does not impede the diffusion of water vapor, but does not allow moisture to pass into the building envelope.

The facade, and all its elements, receive additional insulation and protection from the harmful effects of the environment and the sun. The material has been approved by leading building institutes and approved by the Ministry of Culture for use on historic buildings.

Moisture, chemical elements do not penetrate into the masonry, UV is 100% reflected.

Destruction of the facade and decorative elements is excluded, there is no peeling of the facade paints. Facades have a neat, well-groomed appearance for 15 years or more. The walls of the temples are covered with an ultra-thin heat-insulating coating, layer 0.8. The facade is protected from moisture, plaster destruction and freezing. After reconstruction of the facade with the use of liquid thermal insulation. Facades of houses to be overhauled and reconstructed.

Problem - As a rule, these are buildings built 40-60 years old, made of reinforced concrete panels and foam-aerated concrete. Currently, the thermal insulation does not meet the requirements of energy saving

Interpanel seams and walls of buildings made of foam concrete are constantly exposed to the destructive effects of moisture, chemicals, thermal and ultraviolet radiation from the sun.

Cracks, leaks, mold and mildew are common in these buildings.

Insulation methods for such buildings are imperfect, do not meet the requirements of the law, the materials used are prohibited by Art. 26, in view of the lack of durability and low energy efficiency, and create unnecessary weight loads on foundations that are not designed for this.

Solution - After sealing the interpanel seams, sealing cracks and additional leveling plaster along the facade mesh, liquid thermal insulation Korund is applied to the facade of the building, 0.8 -1.6 mm thick, including the slopes of doors and windows.

Result - Liquid thermal insulation encloses the building facade, window and door slopes with a continuous, seamless membrane. The coating does not impede the diffusion of water vapor. The facade receives additional insulation and protection from moisture and chemical elements. 100% UV, 85% of the sun's thermal energy is reflected back into the atmosphere. There are no weight loads on the foundation, thermal loads are eliminated. Damage to the facade is excluded, there is no peeling of facade paints.

Facades have a neat, well-groomed appearance for 15 years or more.

New construction of residential and public buildings.

Problem - Thermal insulation materials used in the construction of new residential and public buildings, today, are directly prohibited for use, article Federal law as not durable, not energy efficient and not energy saving.

Currently, as a rule, two types of insulation are used - plaster based on "traditional" insulation and "traditional" insulation, covered with a ventilated facade.

The durability of load-bearing structures and walls of newly erected buildings is estimated at 100 years, the durability of heaters is 3-5 years, therefore both types can be defined as "anachronistic", highly costly, and life-threatening. With the best quality of installation of mineral wool (basalt) heaters, it is not possible to obtain a continuous, seamless coating. There are air gaps between the walls 3) and the insulation layer, as well as between the insulation plates. This creates conditions for the formation of condensation in the pores of the insulation and on the walls.

Insulation accumulates moisture not only in the form of vapors, but also in the form of water droplets that penetrate through microcracks in the plaster and holes in the windproof film. The moistened insulation sharply reduces the resistance to heat transfer of the structure (an increase in the moisture content of the insulation by 1%, increases its thermal conductivity by 4%).

The alternating temperatures form ice microcrystals that break the bonds in the insulation. Air cavities increase, condensate and ice becomes larger, the process of destruction progresses. After 3-4 years, destructive phenomena are already developing in a power dependence.

After 5 years of operation, the insulation is a loose, crumbling "substance" with rotten fasteners and very low resistance to heat transfer. Frost penetration, mold and mildew appear in the residential area.

Insulation of the facade is practically absent!

A long and expensive process of replacing the entire structure lies ahead.

Also, if the installation technology is violated, the use of low-quality (cheap) fasteners, the collapse of such facades is inevitable, such examples, unfortunately, in Russia were abundant.

Solution - On all types of buildings where mineral wool (basalt) - "traditional" heaters are used, it is possible to replace them with ultra-thin, liquid thermal insulation, at the rate of 1 mm. coverage ≈ 50 mm. mineral wool insulation. Result - The durability of the facade increases tenfold, deductions for major repairs. The enclosing structures are in a warm zone, and the "dew point" is in the middle of a thin layer of liquid thermal insulation.

A comfortable temperature / humidity ratio is established in the premises - it is warm in the building in winter, cool in summer. Complete absence of metal fasteners on plaster facades. The facade has an attractive, neat look.

In buildings of the "ventilated facade" type, there is no need for vapor and wind protection films, and for expensive (long-sized) fasteners, there is no need for facade ventilation! In all variants, cold bridges are eliminated. Comments - unnecessary panel, brick buildings, liquid thermal insulation is made only with Corundum coating, with a layer of 1.6-2.0 mm. Monolithic frame buildings with self-supporting external walls have several catastrophic problems:

Problem 1 - Thermal insulation of the protruding ends of the floor slabs is carried out by means of "thermal inserts". The method proposed by Len "SpetsSMU" is so absurd and not durable that it causes "bewilderment" not only among designers, but also among builders. Thermal inserts are used from the cheapest foam, or min. cotton wool. They are laid, for the most part, wet (it rains and the gap between its laying and the masonry of the wall is large, and the masonry mortar is wet) and it turns out that its thermal conductivity is equal to the thermal conductivity of water - i.e. no insulation.

And then according to the scheme - moisture-ice, moisture-ice, and after 3 years there is dust in the place of the thermal insert and no repair will help, because it is located between the slab and the brickwork of the wall. In Russia, there is a huge number of buildings with freezing ceilings, without any prospects not only for energy saving, but also for repairs!

Problem 2 - Buildings with such walls (brick and foam concrete, in the form of insulation, inside) are prohibited in Europe.

The insulation should not be inside the premises, because the wall will be in a cold zone, and the dew point is next to the wallpaper, there is no heat accumulation effect, the temperature / humidity ratio is a "barrack-type" climate.

The solution is to prohibit the use of thermal liners and internal insulation

For new construction - floor slabs, after the construction of a monolithic frame, treat with Corundum coating, 1.6-2.0 mm thick (the end of the slab, adjoining surfaces (floor / ceiling) 150-200 mm wider than the wall to be laid), or exclude foam concrete from of the inner layer of the wall structure, and the wall should be insulated from the outside by brick 4) _Liquid thermal insulation ≈ 2.0 mm, or plaster by brick, followed by applying Corundum Thermal insulation.

Operated buildings - apply a coating of liquid thermal insulation, 1.6 mm thick, to the ends of floor slabs with the capture of layers of masonry from above and below on one or two bricks.

All problems can be eliminated very simply and the issues of further energy efficiency and energy saving of these buildings can be solved.

Solving the issues of energy saving and energy efficiency of residential and public buildings, in the light of Federal Law No. 261-FZ, when using a coating with liquid thermal insulation.

After the approval of the Federal Law No. 261-FZ, in many regions of Russia and the cities of Petrozavodsk, Samara, Kazan, Vladivostok and others, the programs "energy efficient quarter" were adopted.

Currently, we have made a proposal to change the project of panel houses, in order to increase durability, energy efficiency and energy saving.

The proposal is as follows:

After the installation of the panels is completed, the front part of the facade is treated with liquid thermal insulation Korund - in two layers (0.8 mm), with the capture of window and door openings;
- a leveling layer of cement-sand plaster is applied along the grid;
liquid thermal insulation is applied to the plaster (four layers, 1.6 mm thick), with tinting of the last layer or applying a finishing layer of facade dye;
- on the inner part of the panels, behind the batteries, 1 layer (0.4 mm) of liquid thermal insulation is applied;
- the required number of layers of Korund thermal insulation (thickness ≈ 2.4 mm) is applied to the cement-sand roof screed, and internal gutters and surfaces of parapets are also treated with this coating;
- shut-off valves of heating systems are used, with automatic temperature control in the premises;
- heating points of the building are equipped with an automatic control and metering system for heat energy consumption, cold and hot water consumption.

Result - The entire building (from roof to foundation) is covered with a continuous, seamless thermal insulation membrane Korund, including the slopes of windows and doors. The coating has 100% adhesion, elastic, vapor permeable, durable.

In summer, 100% of the ultraviolet flux and 85% of the solar thermal energy are reflected by liquid thermal insulation and glass units back into the atmosphere. There is no need to install air conditioners - the rooms are cool, energy savings are up to 45%.

In winter - 85% of the heat flow is reflected back into the premises, the enclosing structures are in a warm zone - the effect of heat accumulation appears.

The "dew point" is located inside the first layer of liquid thermal insulation (thickness 0.8 mm.), In the range of humidity from 40 to 90% and does not have a destructive effect on the facade.

Heat shields, behind the radiators, increase the temperature in the premises by 3 ÷ 4 ° C and eliminate temperature stresses in the panels.

Economic indicators (costs) during construction and operation are formed from the following items:

Reduction of construction time - the productivity of work on the application of 6 layers (2.4 mm.) With thermal insulation Korund = 20 m2 / hour (one layer of 0.4 mm - 100 m2 / hour), versus 8 hours / m2, during the work "plaster on a min-plate ";
- reducing the weight of the facade insulation system by 16 times (the applied method is ≈ 16 kg / m2, the proposed method is 0.9 kg / m2) - this makes it possible to obtain savings while lightening the foundations;
- the durability of the facades increases tenfold - deductions for major repairs are not needed, the risks of emergency repairs are excluded;
- the appearance of "efflorescence", peeling of paint - are excluded, as it gets dirty, only the facade is washed;

The adoption of the solutions described above allows not only to reduce the construction time, increase the durability of buildings, solve the problems of energy saving, but also to obtain significant budget savings.

3. Problem - Energy saving - heat losses.

The only country in Europe is Russia, where huge losses of thermal energy are commonplace everywhere and everywhere, it’s time for the prosecutor’s office to deal with it.

Heat generating enterprises are not just to work there, but it’s scary to go there. Dust, dirt, smell of incompletely burnt fuel. Everywhere there are leaks, steam leaks, hanging dirty scraps of mineral wool, a huge number of naked, hot pipelines. Outdoor equipment has no less depressing appearance - hot water and cold water tanks in icicles (increased heat loss), rusty, dented lining, sticking out mineral wool, network pipelines in the same state. Well, right, some kind of the Middle Ages.

Heat networks are generally a separate "novel", episodes of which are regularly shown to us on television. Widely "promoted" and approved polyurethane foam does not have sufficient linear expansion. At the first start-up, the pipe cracks.

Abundant heat loss and very intense corrosion begin (ten times more intense than with a bare pipe). It is a crime to use such pipes, but every year they are stubbornly buried in the ground in order to get another accident after a while.

The cost of thermal insulation today is almost the same and depends little on the type of insulation chosen.

Nevertheless -

1. The service life of thermal insulation made of "traditional" materials is 2-5 years.

2. The service life of liquid thermal insulation is 15 years.

Therefore, when operating, investing money

repair of pipes and replacement of "traditional" heaters will have to be 4 times

more often and 4 times more than in the case of ultra-thin thermal insulation Korund.

Why do "traditional" heaters serve so little?

1. There is always an air gap between the pipe and the insulation.

2. The insulation itself is capable of accumulating moisture, both in the form of vapors and in the form of drops.

An increase in the moisture content of the insulation by 1% causes an increase in thermal conductivity

material by 4%, the higher the moisture content, the greater the thermal conductivity.

The thermal conductivity of "wet" insulation is equal to the thermal conductivity of water - 0.56 W / mC, the formation of ice not only increases the thermal conductivity to 2.2 W / mC, but also destroys the material. In this case, all conditions are created for the formation of condensation in the air gap, which leads to intensive corrosion of the metal.

Thermal insulation Corundum adhesion to metal is 100%, there is no air gap, water is not allowed through, they are durable, their thermal conductivity does not change, therefore, the above phenomena are completely absent! Solution - Given economic efficiency, energy-saving and energy-efficient indicators, durability, anti-vandalism, ease of application and maintainability to apply liquid thermal insulation to insulate equipment, pipelines, equipment in open areas, network pipelines and pipelines of any method of laying CHP, boiler houses and heating networks. Consider thermal insulation from an economic point of view.

EXAMPLE Hot water heating main (overpass type). Length - 1000 m. Pipe diameter - 1020 mm. The heat carrier is water of 100 ° C.

The surface area of ​​the heating pipe is measured from the outer edge of the insulation coating, therefore the total surface area will be different for different types of thermal insulation -

1. Thickness of insulation made of "traditional" materials - 100 mm.

2. Thickness of thermal insulation Korund - 1mm.

The total surface area of ​​the heating main will be -

1. "Traditional" materials - 3831 m2. (An increase of 20% of the actual area)

2. Ultra-thin liquid thermal insulation - 3203 m2. (true area)

Consequently, the estimated cost when using "traditional" materials will be 20% more than with Thermal insulation Korund,

and taking into account additional elements and time costs for work, it can be all 30% -40%, and will increase the construction time.

Conclusion: The use of Korund ultrathin thermal insulation allows to increase the turnaround time by 4 times, to reduce the estimated cost of construction work by 20-30% (even if the cost of 1m2 of ultrathin thermal insulation coating is higher), to reduce the construction time.

Consider thermal insulation in terms of energy efficiency.

Permissible standard heat losses on this heating main is 51 W / m2.

Heat losses will always occur, but their magnitude depends on the type

the insulation used and the radiated surface area (W / m2).

Based on the norms of heat losses, the real losses on the heating main will be -

1. "Traditional" materials - 195381 W, or 0.17 Gcal / hour, or 1489 Gcal / year.

2. Ultra-thin insulation -163353 W, or 0.14 Gcal / hour, or 1226 Gcal / year.

Additional heat loss in relation to liquid thermal insulation,

when using insulation with "traditional" materials = 263 Gcal / year (with a length

slopes 1000 m.), or 339 836 rubles / year. (we accept the cost of 1 Gcal = 1,294.12 rubles)

This is true only at the beginning of operation, as the destruction of "traditional" materials, in 2-3 years, heat losses will grow in a power-law progression and

respectively the amount of monetary losses. The track will warm the atmosphere.

If we multiply the cost of losses from one kilometer of pipe by the number of kilometers of pipelines in urban networks, equipment of numerous boilers and thermal power plants, then the amount of losses will be commensurate with the profit of "GUP TEK SPb" for the year (they lost as much as they earned)!

Conclusion: The use of liquid thermal insulation will reduce unproductive losses of thermal energy, reduce fuel consumption at generating enterprises in the city, fully protect equipment, pipelines, heating mains (any method of laying) from corrosion and condensation.

The proposed thermal insulation Korund is fully certified in Russia, fully meets the requirements of the Federal Law

No. 261-FZ "On energy saving and increasing energy efficiency"

(Art. 26) while many "traditional" materials, in view of their low energy efficiency (which was proved above) and durability, do not comply with the norms of this law and are prohibited for use.

The above calculations and conclusions are valid for any type of heating equipment, regardless of its location.

According to our calculations, with the abandonment of "traditional" heaters and the use of modern, durable, highly energy-efficient and energy-saving coatings of liquid thermal insulation, a decrease in the estimated cost of thermal insulation work by 35%, a decrease in unproductive heat loss during operation by up to 45%. Liquid insulation is indispensable in modern conditions.

Liquid insulation

The development of technologies in the field of construction allows the use of energy-saving materials that preserve the heat of our houses as much as possible. Liquid thermal insulation, which works on the principle of reflection from a heat source of infrared rays, is one such material.

Often, a huge amount of heat "leaves" through the so-called "cold bridges" - places that quickly cool regardless of the quality of heat in the house: the corners of rooms, ceiling joints and interpanel seams, slopes, foundations, floor structures, etc. In this case, it is possible to avoid energy leakage if you paint over these areas with Corundum - insulation will help reduce the effect of "cold bridges", thereby saving up to 30% of heating costs.

Such insulation will become an indispensable solution for residents of apartment buildings. Due to the fact that the housing and communal services constantly regulate the hot water supply of houses with the help of metering devices, many residents do not receive the necessary heat due to the fact that their apartments have more "cold bridges" (often corner rooms) than others. It is possible to eliminate heat leakage once and for all by painting problem areas with a Korund heat insulator in several layers, I follow the interlayer drying technology (for a 100% result, it is necessary to conduct a thermal imaging survey of the room, check the humidity level and the health of ventilation). After all layers are completely dry, the surface can be pasted over with wallpaper, painted in the desired color, decorated, etc.

Thermal insulating material Corundum is easily applied to the surface: special skills are not required to work with it, it is enough to read the instructions and follow them, the product has practically no technological and environmental restrictions. Heat insulator Korund is certified in Russia and Belarus.

Corundum paint

The use of paint is wide enough:

Thermal insulation of facades of residential and industrial facilities;

Insulation of corner and ceiling joints;

Processing of interpanel seams;

Thermal insulation of pile ends, basement walls and basement floors;

Insulation of pipes for cold and hot water supply, gas pipelines and gas fittings;

Thermal insulation of the roof and roof canopies for protection from icicles, frames of pre-fabricated structures;

Insulation of vehicles;

Processing of valves at power facilities; at oil refineries;

Thermal insulation of gas transmission storages and pipelines;

Thermal insulation of balconies and loggias, masonry joints, window and door slopes;

Thermal insulation of containers to protect against temperature deformations;

Thermal insulation of monolithic concrete floors, walls overlooking the stairs;

Insulation of garbage chutes;

Heat and sound insulation of ventilation ducts, electrical substations, electrical cabinets, boxes at telephone exchanges;

Thermal insulation of refrigerated cars, ships and barges, metal furniture and other metal structures.

In order to complete the construction of the building with high quality and forget about repairs for a long time, special attention should be paid to atwarming the facades of residential and industrial buildings heat-insulating paint. To do this, the outside facade, after cleaning from dust and dirt, is painted in 3-4 layers over the entire area, allowing each previous layer to dry completely. If the facade is finished with tiles, then the wall is treated with a primer before work. Window slopes should be painted outside and inside.

The advantages of Korund insulation are not only that it is a high-quality heat insulator - its service life exceeds 15 years, which means that you will forget about repair work for a long time. During the repair of the wall, the thermal insulation coating will not need to be completely removed - only restored without losing the thermal properties of the thermal insulator. And if we compare the paint Korund with such traditional materials for insulation as polystyrene, mineral wool, etc., then the savings on dismantling and exporting the insulation becomes obvious (let alone the mountains of garbage and dust left after working with such materials!).

If wallpaper is pasted in the places of the planned processing, they should be removed, the wall should be cleaned of dust and dirt. If there is mold, the area is cleaned and treated with an antiseptic. Then the cleaned and dried wall is covered with a primer and allowed to dry. After the preparatory work, we proceed to the main, painting: we apply the paint-insulation Corundum in several layers, observing the time-out for interlayer drying at 6 o'clock. With a heat gun and good ventilation, drying time can be significantly reduced. The finished coating should be uniform white (the first layer should be translucent!).

The optimum indoor humidity will be less than 60% and the temperature above + 18 ° C.

For accurate measurement of these indicators, we recommend a household electronic combined thermo-hygrometer, a remote sensor of which is mounted on the wall surface. With the help of it, you will be able to control the microclimate of the room and, based on its testimony, make complaints to the housing and communal services services if the microclimate of the apartment by some criteria does not meet the sanitary and hygienic standards in accordance with SNiP 23-02-2003.

How will the insulation of interpanel seams help against leaks and heat loss?

Outside, we thoroughly clean all the seams from old paint (if any), dirt and dust. Next, paint Corundum in several layers (usually 4-5) along the entire length to a width of 0.6-0.8 meters.

In natural areas with severe winters and permafrost, thermal insulation of pile ends is relevant. , the ends of which freeze when inside the premises. The sequence of works will be as follows: the pile is first heated, wiped dry, dried. Then it should be primed, dried and then painted in 8-10 layers with Corundum insulation. The pile must be heated until the thermal insulation layer is completely dry!

Thermal insulation of walls of basements, cellars and basements, basement ceilings will prevent freezing: it is necessary to insulate the outside with heat-insulating materials, and inside the surface with a paint-insulating material Korund. So you get rid of dampness, increase the temperature in the room. Pay attention to the health of the ventilation: if the wall temperature rises, then it is quite possible that the "dew point" will move outside the wall, both outside and inside, and this will lead to the fact that the humidity in the room will increase with non-functioning ventilation, as a result of which dampness and fungus.

Thermal insulation of pipes for cold and hot water supply will help to increase the resource of pipelines by 30-40% .

Very powerful "cold bridges" are formed near the routes of cold and hot water supply passing nearby. Because of this, condensation constantly forms on the pipes, which has a detrimental effect on the metal of the pipelines. Thermal insulation will solve this problem and significantly reduce the heat loss of the pipes.

At the preparatory stage of work, the pipes are wiped dry, primed (if not galvanized), and allowed to dry. Next, apply 1 layer of insulation Corundum and leave to dry. Then the next two layers are applied in the same way. Each layer should not exceed 1 mm in thickness. You will see the heat-insulating effect immediately after the layers have dried.

Insulation of gas pipelines and gas fittings with Korund paint will help reduce the heat transfer of metal pipes and reduce the cost of preheating gas by about 10-15%. For pipelines of direct bedding, the insulation Korund Anticor has been specially developed, which is at the same time an anti-corrosion and waterproofing material.

For thermal insulation of roof slabs, 4 layers of Liquid thermal insulation Korund are enough to restore the protective properties of the roof.

Recently, prefabricated houses are more and more in demand. A special task in such construction is the thermal insulation of the frames of pre-fabricated buildings, since metal frames are precisely the "cold bridges".

In this case, all frames and fasteners are treated with paint with liquid thermal insulation. In case of economy, the hats of the fasteners are painted (since through them the heat "evaporates" outward).

This liquid thermal insulation is indispensable in the matter of insulating cars and other vehicles: thermal insulation of the body from the inside in several layers will make the operation of an air conditioner or heater more tangible. Painting should be done in a workshop or equipped garage.

The technology of works on thermal insulation of shut-off valves at power facilities is slightly different from those described above. The preparatory stage is unchanged. But the first layer of Corundum is applied to the reinforcement with vigorous rubbing movements. After the temperature of the metal has dropped slightly, the next 7-8 layers can be applied in normal mode... The interlayer drying time will already depend on the ambient humidity and will be 2-6 hours.

Insulation of balconies and loggias is based on painting the balcony slab with insulation, adjacent wall sections, slopes, attachment points, seams and joints exposed to the destructive effect of atmospheric precipitation.

Thermal insulation of masonry joints is equally important! And do not think that during the construction all the seams were carefully sealed, and concrete blocks will reliably protect from frost and wind. In fact, a large amount of heat escapes through the seams between blocks or slabs, and you can verify this with the help of a thermal imager used in the thermal imaging analysis of a room (it was mentioned at the very beginning). In the course of the analysis, energy holes are noted, and their size is calculated. Then it remains only to paint over the marked places (of course, after cleaning and priming the surface before painting) with a heat insulator in 2-3 layers.

Insulation of window and door slopes comes down to the fact that the slopes and seams themselves are painted over with insulation, forming "cold bridges" in several layers.

To protect containers from thermal deformations during the collection and transportation of hot waste with uneven heating, you can also use the Korund Classic heat-reflecting paint.

In residential buildings, it is relevant to insulate monolithic concrete floors, since these concrete blocks have a higher thermal conductivity (and, as a result, heat leakage) than hollow ceilings. You can, of course, go the traditional way: insulate with glass wool or foam, but at the beginning of the article we have already seen the entire inexpediency of this solution. It is enough to apply 3-4 layers of liquid thermal insulation to solve the problem.

In apartment buildings, the “energy hole” is often the walls facing the staircase (kitchen walls). They are much colder than the rest of the walls in winter, and therefore condensation often appears on them. Due to the high humidity in the room, a fungus can settle. To avoid this, it is enough to cover the problem wall surface with 4 layers of Korund heat insulator, observing the interlayer drying regime for 24 hours. The temperature of the wall should not be lower than + 5 ° С when painting.

Insulation of garbage chutes, ventilation ducts is necessary to prevent dust from settling on the walls due to condensation, creating an easily flammable "fur coat". For thermal insulation, 3-4 layers of Korund insulation will be enough outside. In addition, the insulation layer will still work as a sound insulator.

Thermal insulation of electrical substations is also primarily a protection against temperature extremes and the appearance of condensation - one of the root causes of short circuits. For reliable heat and anti-corrosion protection, paint the inside of the walls of the substation with heat-insulating material Korund Classic in only 3-4 layers.

Thermal insulation of electrical cabinets with liquid thermal insulation is carried out for the same reason as above. The insulation technology is the same.

Again, condensation is the reason for the thermal insulation of boxes at telephone exchanges. To protect the brackets and contacts from corrosion, paint the metal parts with a heat insulator Korund Anticor.

Insulation of refrigerators should be carried out by painting the outside with 4 layers of insulation Korund Facade.

Thermal insulation of landing stages, ships and barges using polymer materials Korund Classic, Korund facade can become a panacea on modern ships for the heat in summer and freezing in winter in conditions of an acute shortage of space.

Thermal insulation of subway tunnels is needed to reduce the level of humidity. It is produced by painting the prepared walls and ceilings with several layers of insulation.

According to statistical data, about 90% of houses in Russia do not meet modern heat-saving standards. To improve the situation, a number of legislative acts and sectoral decrees have been adopted recently to ensure the performance of buildings, taking into account the requirements, all new buildings are being erected using modern heat-saving technologies. What about old buildings? It is necessary to insulate the facade walls, due to this, losses are reduced to 40%. There are quite a few heaters, in the article we will consider only one type of them - liquid.

Taking into account the application technology, composition and performance characteristics, all types of liquid heaters can be conditionally divided into two types: ultra-thin and foam. Ultra-thin (warm-colored paints) - the newest development of building materials technologists, universal application. Ultrathin insulation significantly reduces the cost of insulating facade walls, shortens the time of work and improves quality. But they also have negative sides, we will tell about them in the course of the article.

Heatpaints

In appearance, they are almost indistinguishable from ordinary acrylic paints, despite the various trade names they have an almost identical structure.

The material includes:

  • glass-ceramic microscopic spheres. Diameter 0.05-0.1 mm;
  • aluminosilicate microspheres. To increase the heat saving indicators, there is partly no air inside;
  • titanium dioxide. It has a minimum weight, the porous structure prevents the transfer of heat from warm surfaces to cold air;
  • special latex mixture. Increases resistance to hard ultraviolet rays, compensates for thermal expansion, prevents the appearance of microcracks;
  • acrylic. The base of the paint has excellent adhesion to most building materials.

High-quality liquid heaters are highly effective, 1.2 mm of the coating in terms of heat-saving indicators correspond to 5 cm of mineral wool. The effect is achieved due to the presence of a large number of hollow microspheres, which minimizes losses due to ordinary convection. Shiny microspheres additionally reflect infrared rays, the coating also works like a thermos.

Liquid insulation can be applied with ordinary rollers and brushes or special sprayers. But there are also disadvantages to such materials:

  • high cost of thermal paints;
  • short storage times;
  • great loss of quality in violation of storage conditions;
  • manufacturers do not provide accurate data on heat-shielding properties; thermal insulation is performed by eye. It is even theoretically impossible to accurately calculate the required thickness of the insulation layer, everything is determined by the practice of operating already processed structures.
  • high-quality thermal insulation may require up to 10 layers of paint;
  • the actual consumption always exceeds the one indicated on the package.

How to choose a quality liquid insulation

We have already mentioned that these materials significantly deteriorate their properties due to long-term or improper storage. What to look for when buying dyes?

  1. The lower the density of the paint, the better its heat-saving performance. A ten-liter plastic bucket should weigh between 6 and 6.5 kg. If the weight is more, then such insulation is not worth purchasing, its application will not be effective.
  2. Look through the paint in a plastic bucket. Lightweight heat-insulating microspheres rise upward. The thicker this layer, the better the thermal insulation.
  3. Rub a small amount of paint with your fingertips; you should feel a large amount of rough microgranules. The absence of such an effect indicates the manufacturer's dishonesty and the low quality of its products.
  4. The color of the paint must be completely white. A change in color indicates a gross disturbance in the process. This does not apply to paints with mineral color additives.

The recommendations are simple but very effective. The fact is that at present it is not worth paying the main attention to the cost of the goods, some manufacturers deliberately sell low-quality products at high prices in the hope of triggering the stereotype of choice.

Step-by-step instructions for applying warm paint

For example, consider the insulation of a brick wall without plaster. In the future, the facade will be covered with slabs using conventional technology.

Choose a specific brand of insulation. Decide how it will be applied: roller, brush or spray.

Practical advice. If your wall is relatively flat, you can paint it with a roller. If there are deep seams, it is better to paint with a brush, the roller cannot paint such indentations. The best quality coating is obtained while working with a spray gun, this is a unit for universal use.

It must be remembered that painting the front wall several times with a brush is long and difficult. Moreover, you will have to work on a ladder or scaffolding. Calculate your strengths and capabilities correctly.

Step 2. Smooth the wall surface as much as possible. Cut large pieces of mortar with a hammer or chisel, brush away dust.

If there is soil contamination, then it must be washed off. The paint will never stick in dirty meta. As a result - delamination, violation of tightness, significant deterioration of heat-saving performance. The surface of the façade must be dry and the weather good.

Step 3. Prepare paint for use. Perform work in accordance with the instructions, the actual actions depend on the composition and solvent. The consistency should resemble liquid sour cream. Test the material on a small section of the wall. If the paint is too viscous, then dilute it in portions with constant stirring. A large amount of water significantly reduces the thickness of one layer of the coating. As a result, you will have to increase their number, and this is an additional waste of time and effort.

Step 4. Pour paint into a roller container. The roller should have a pile of medium length, such a tool captures more paint at a time. Dip the roller in a container, take it out and spin it on a special platform. It is located slightly above the paint pouring point. Immerse the roller in the paint again and roll again on the pad. Do this until the roller absorbs the maximum amount of ink evenly around the entire circumference. Before removing the roller from the container, give it a rotation, in this state, the paint will not drip to the ground.

Step 5. Bring the roller up to the wall and press it down with moderate pressure. The first pass must be done from the bottom up, the surplus of the helmet will be squeezed out, immediately fall under the roller and evenly distributed over the surface of the front wall.

Step 6. Paint the wall in patches, avoid gaps. Remember that surfaces must not be exposed to rain for at least 24 hours. If the weather turns bad, protect the painted surfaces from getting wet. For protection, you can use plastic wrap, fix it to the front wall or scaffolding, if used during work.

Apply the second layer only after complete polymerization of the first, if the first time you applied the insulation with vertical movements of the roller, then the second time you need to paint with horizontal movements.

Plastered walls can be finished with colored heat paints, in this case, the insulation will simultaneously act as a finishing decorative coating. In the same way, you can insulate wooden surfaces, including log cabins from rounded logs.

Fulfillment of several general practical recommendations for applying thermal paints can reduce material consumption, reduce processing time and improve the quality of the coating.


The material has many technical names, but all types are made on the basis of ordinary foam. During production, synthetic urea-formaldehyde resin, foaming agent, phosphoric acid and water are used. As seen from chemical composition, calling this product "environmentally friendly" can only be a stretch. Liquid foam is especially harmful during application - be sure to protect your eyes and respiratory system. The density of the material depends on the amount of resin, pay attention to its percentage during the purchase of goods and the manufacture of foam.

Liquid foam is applied to the walls with a complex apparatus using compressed air in metal cylinders (mobile version) or connected to a stationary compressor. The components are loaded into the mixer, water is added, the mixer is hermetically closed. Liquid foam is supplied under pressure to the surface, the thickness of the insulation layer is manually adjusted. There is foam with high rates adhesion, used to insulate open surfaces of facade walls for finishing. This technology is often used during the construction of frame houses. The inner space of the wooden frames is insulated, and after the foam has set, the finishing of the facade surfaces of the bearing walls is done.

The second option is to insulate the space between the load-bearing wall and the facade cladding. Work can be performed both during new construction and when insulating old buildings with an air gap. We will tell you about the second option in detail.

Insulation - liquid foam

The heat-saving efficiency of unfilled air spaces is very low and never meets the design indicators. The fact is that the facade masonry of the wall has quite a few holes of various sizes. They are found in the seam between the bricks, and at the junction of window and door openings, and at the places where the truss system is installed. At first glance, the holes are completely invisible, but as the space is filled with liquid foam, the material will show through in each of them, and you will be unpleasantly surprised by the large amount. There is no need to get upset, after the foam hardens, it is carefully cut off, the visible cut is closed. For such insulation works, a special liquid foam is used, which does not stick, but is repelled from the surfaces of architectural elements. This allows a large amount of space to be filled through one opening.

Professional advice. Many inexperienced builders think that foam plates, laid in the air space between the wall and the cladding, reliably insulate the house. This is fundamentally wrong. Foam boards only "work" when no air circulates between them and the wall. For this, the surface of the facade wall must be flat, the glue on the slabs must be applied with a comb-type trowel over the entire area in horizontal stripes. In all other cases, the actual heat saving is no more than 10% of the calculated one, energy is lost due to air draft between the warm wall and the foam.

Have you identified a lot of houses where the foam on the facade walls was fixed in the way we described? Or, in the worst case, the glue was carefully applied with a trowel along the entire perimeter of the sheet without gaps and in several places in the middle? All other options are literally down the drain. You can correct the situation with liquid foam. How is the facade wall insulated?

Technology of thermal insulation of facade walls with liquid foam

Step 1. Prepare materials and tools. In addition to a special unit, you will need an electric perforator and drills with victorious solders for the diameter of the filler tube.

Step 2. On the front wall, in a checkerboard pattern, drill holes in the seams between the bricks, the distance between them is about 1 meter. Foam will flow through the holes. Immediately prepare wooden pegs of the appropriate diameter to temporarily plug the holes while foaming the space between the walls.

Drilling holes

Step 3. Prepare the unit for filling liquid foam. Start filling the space with foam from the bottommost hole. The air pressure cannot be more than 5 atm., Otherwise there are risks of cracks on the facade cladding. Due to the fact that the space between the walls is small, reduce the amount of material supplied. The specific values ​​are determined in a practical way. Do not rush to take on the whole house at once, set up the operating modes in a small area, preferably on the back of the house.

Step 4. You need to work with an assistant. One turns on / off the supply of liquid foam, and the second installs a branch pipe in the holes and monitors the filling of the space with foam. As soon as foam appears from a nearby hole, it is closed with a wooden wedge, the foam is stopped, the pipe is inserted into the adjacent hole.

Step 5. Always work from top to bottom. If foam does not appear in the adjacent hole for a long time, reduce the distance between them or slightly increase the pressure in the system.

Practical advice. Blow the air from the compressors into the openings before filling the space with foam. Check if it goes out everywhere, there are no dead zones. If such areas are found on the front wall, you need to drill new holes nearby and repeat the air test.

If the wall is not properly laid, then turn off the unit immediately when foam appears from the cracks in the masonry mortar. Drill the filling and control holes on these facades closer to each other.

Step 6. Using this method, blow out all the front walls around the perimeter of the building with foam, close the control and filling holes with wedges.

This completes the work on insulating the front walls with liquid foam. The next step is to remove the remaining foam. On the facade walls, prepared for finishing plastering or finishing with other materials, you should simply break off large pieces of frozen foam with your hands.

If the facade wall is already finished with decorative facing bricks, then the traces of foam must be removed with a clean, damp cloth. It is not difficult to do this, the work does not require a lot of time. After removing the foam, you will have to slightly clean the filler holes from the foam and seal them with a cement-sand mortar to match the color of the seams.

It is difficult to find the same composition of the mixture - not a problem. Seal the holes with any solution, after it dries, paint the seams with a suitable color. This will take a little more time, but the appearance of the facade walls will completely change, mosses and mold will be removed from the seams. And this, in any case, would have to be done, the personal home constantly requires care.
