We make liquid thermal insulation with our own hands. Review of liquid insulation for walls: characteristics, pros and cons What is liquid thermal insulation

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

Taking into account the application technology, composition and operational characteristics, all types of liquid insulation can be divided into two types: ultra-thin and foam. Ultra-thin (warm paints) are the newest development of building materials technologists, universally applicable. Ultra-thin insulation materials significantly reduce the cost of work on insulating facade walls, reduce work time and improve quality. But they also have negative sides, we will talk about them throughout the article.

Warm paints

In appearance they are almost indistinguishable from ordinary acrylic paints, despite different 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 heat saving indicators, there is partially no air inside;
• titanium dioxide. It has minimal 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 paint base has excellent adhesion to most building materials.

High-quality liquid insulation materials are highly efficient; 1.2 mm of coating corresponds to 5 cm of mineral wool in terms of heat-saving indicators. 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 as a thermos.

Comparative table of performance indicators of thermal paints and traditional insulation materials. The table uses average paint characteristics.

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

• high cost of thermal paints;
• short shelf life;
• large loss of quality due to 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 treated structures.
• high-quality thermal insulation may require up to 10 layers of paint;
• actual consumption always exceeds that indicated on the packaging.

How to choose high-quality liquid insulation

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

1. The lower the paint density, the better its heat-saving properties. A ten-liter plastic bucket should weigh between 6–6.5 kg. If the weight is greater, then such insulation is not worth purchasing; its application will not be effective.
2. Hold the paint in the plastic bucket up to the light. 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 paint color should be completely white. A change in color indicates gross violations of the technological process. This does not apply to paints containing mineral color additives.

The recommendations are simple but very effective. The fact is that currently you should not pay the main attention to the cost of the product; some manufacturers deliberately sell low-quality products at high prices in the hope that the choice stereotype will be triggered.

Step-by-step instructions for applying heat paint

Using an example, let's look at the insulation of a brick wall without plaster. In the future, the facade will be covered with slabs using conventional technology.

Select 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; a roller cannot paint such recesses. The highest quality coating is obtained when working with a spray gun; this is a unit for universal use.

It must be remembered that painting a façade wall several times with a brush is time-consuming and difficult. Moreover, you will have to work on a ladder or scaffolding. Correctly calculate your strengths and capabilities.

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

If there is soil contamination, it needs to be washed off. Paint will never stick in dirty places. As a result, peeling, loss of tightness, and a significant deterioration in heat-saving indicators occur. The surface of the facade should be dry, the weather should be good.

Step 3. Prepare the paint for use. Perform the work according to the instructions; 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 portionwise with constant stirring. A large amount of water significantly reduces the thickness of one coating layer. As a result, you will have to increase their number, which means additional loss of time and effort.

Step 4. Pour the paint into a special container for the roller. The roller should have a medium-length pile; such a tool will capture more paint at a time. Dip the roller into the container, take it out and spin it on a special platform. It is located slightly above the area for pouring paint. Dip the roller into the paint again and roll it around the area again. Do this until the roller has absorbed the maximum amount of paint evenly around the entire circumference. Before removing the roller from the container, rotate it; in this state, the paint will not drip onto the ground.

Step 5. Bring the roller to the wall and press it to the surface with medium force. The first pass must be made from the bottom up; the excess helmet will be squeezed out, immediately fall under the roller and be evenly distributed over the surface of the facade wall.

Step 6. Paint the wall in sections, do not allow gaps. Remember that surfaces should not be exposed to rain for at least 24 hours. If the weather turns bad, protect painted surfaces from getting wet. For protection, you can use plastic film, fix it to the facade wall or scaffolding, if one is 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 thermal paints, in which case the insulation will simultaneously serve as a finishing decorative coating. In the same way, you can insulate wooden surfaces, including log houses made of rounded logs.

Following 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 plastic. During production, synthetic urea-formaldehyde resin, foaming agent, orthophosphoric acid and water are used. As can be seen from the chemical composition, calling this product “environmentally safe” 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 when purchasing a product and making foam.

Liquid foam is applied to the walls using 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, and the mixer is sealed. Liquid foam is supplied under pressure to the surface, the thickness of the insulating layer is adjusted manually. There is foam with high adhesion rates that is used to insulate open surfaces of facade walls before finishing. This technology is often used during the construction of frame houses. The interior space of the wooden frames is insulated, and after the foam has hardened, the finishing of the facade surfaces of the load-bearing walls is done.

The second option is to insulate the space between the load-bearing wall and the façade cladding. The work can be carried out both during new construction and during insulation of old buildings with an air gap. It is the second option that we will talk about in detail.

Insulation - liquid foam

The heat saving efficiency of unfilled air spaces is very low and never meets the calculated values. The fact is that the façade masonry wall has quite a lot of holes of various sizes. They are present in the seam between the bricks, and at the junction of window and door openings, and at the installation sites of the rafter system. At first glance, the holes are completely invisible, but as you fill the space with liquid foam, material will appear in each of them, and you will be unpleasantly surprised by the large number. There is no need to be upset; after the foam has hardened, it is carefully cut off and the visible cut is sealed. For such insulation work, a special liquid foam is used, which is not glued, but is repelled from the surfaces of architectural elements. This allows you to fill a large volume of space through one hole.

Professional advice. Many inexperienced builders think that foam boards laid in the air space between the wall and the cladding reliably insulate the house. This is fundamentally wrong. Foam boards only “work” when air does not circulate between them and the wall. To do this, the surface of the façade wall must be flat, and the adhesive on the slabs must be applied with a comb spatula over the entire area in horizontal stripes. In all other cases, actual heat savings are no more than 10% of the calculated ones; energy is lost due to air draft between the warm wall and the foam.

Have you identified many houses where polystyrene foam was fixed on the facade walls using the method we described? Or, in the worst case, was the glue 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 money down the drain. You can correct the situation with liquid foam. How is a façade wall insulated?

Technology of insulation of facade walls with liquid foam plastic

Step 1. Prepare materials and tools. In addition to a special unit, you will need an electric hammer drill and drills with pobedit tips for the diameter of the filler tube.

Step 2. On the facade wall, drill holes in the seams between the bricks in a checkerboard pattern, the distance between them is approximately 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 liquid foam filling unit for operation. Start filling the space with foam from the lowest hole. The air pressure cannot be more than 5 atm, otherwise there is a risk of cracks appearing in the façade cladding. Due to the fact that the space between the walls is small, reduce the amount of material supplied. Specific values ​​are determined practically. Don’t rush to tackle the whole house at once; set up the operating modes in a small area, preferably on the back side 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 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 supply of foam stops, and 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. Before starting to fill the space with foam, release air from the compressors into the holes. Check if it comes out everywhere and if there are any dead zones. If such areas are found on the facade wall, you need to drill new holes nearby and repeat the air test.

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

Step 6. Using this method, blow foam on all facade walls around the perimeter of the building, and close the control and filler holes with wedges.

At this point, the work on insulating the facade walls with liquid foam is completed. The next step is to remove the remaining foam. On facade walls prepared for finishing plaster 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 traces of foam should be removed with a clean damp cloth. This is not difficult to do; the work does not require much time. After removing the foam, you will have to clean the filler holes a little from the foam and seal them with cement-sand mortar to match the color of the joints.

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 would have to be done in any case; a personal home constantly requires care.

In the modern world, thanks to the latest technologies, various insulation materials appear on the market that have improved characteristics.

Liquid thermal insulation for walls is A relatively new development, which significantly speeds up and facilitates the insulation processes.

The advantage is that the material can be used both.

In addition, anyone can apply thermal insulation; to do this, you only need to arm yourself with a few things.

You can also pay attention to such insulation materials as:

Liquid thermal insulation for walls - what is it, pros and cons, difference from conventional materials

In Western European countries, residents insulate their homes exclusively with heat-resistant paints. This method is also beginning to be used in Russia, but so far its popularity does not exceed 50 percent.

But this type of thermal insulation is in increasing demand and will certainly, in a few years, displace the usual methods of heat conservation.

According to the classics, many construction companies mainly offer to insulate the residential sector with foam plastic, as well as cotton rolls. However, today almost all industrial facilities can no longer do without liquid insulation.

Liquid thermal insulation - characteristics declared by the manufacturer

Disadvantages of the insulator:

• It is worth storing and transporting liquid insulation with strict adherence to temperature indicators;
• High pricing policy;
• It is difficult to correctly calculate thermal conductivity;
• In areas with moderate temperature conditions, it is necessary to apply more than ten balls of paint, which ultimately increases the consumption of material and significantly increases the cost of the repair itself.
• Lots of negative reviews, the essence of which boils down to one thing - the insulating characteristics do not even closely correspond to the declared ones. To achieve good insulation, many layers of paint are required.

Pros:

• Minimum labor costs during operation, you can apply the paint with a roller or a simple brush.
• Large-scale objects can be covered in a short period of time;
• Heat retention by 40-50 percent;
• Before painting it is worth carrying out minor preparatory work;
• Unlike conventional insulation, the liquid version is considered indispensable at the stage of internal insulation of an apartment or house. They can be used to treat hard-to-reach places where the use of rolled or cotton insulation is impossible. In addition, not everyone wants to use the latest materials because of their bulk, which negatively affects the dimensions of the room.

Types of liquid thermal insulation and popular manufacturers

Liquid is considered to be the most popular on the domestic market. thermal insulation from companies:

1. Akterm;
2. Corundum;
3. Astratek;
4. Thermomet;
5. Isollat;
6. Teplosil;
7. Armor;
8. Lic Ceramic.

We will consider the types of liquid thermal insulation according to the latest manufacturer.

1. Standard. Standard thermal insulation is applied exclusively in the spring and summer months. Operating temperature range -58 to +500 Fahrenheit.
2. Ultra. This thermal insulation material is significantly different from the previous version. It has improved thermal conductivity, which is 0.0012. The specific gravity of thermal insulation decreased several times, as a result, this affected the reduction of consumables during coating application. This mixture does not need to be stirred from time to time in liquid form, all because the microspheres are evenly distributed here.
3. Thermo. It is recommended to be used when repair work is carried out in winter or late autumn. Designed exclusively for metal surfaces. The application temperature for this type of liquid thermal insulation is from -4 to +122 Fahrenheit. And the operating temperature is from -58 to + 752 Fahrenheit.

What is the difference between internal and external wall insulation

Wall with external insulation

This application technique considered the most effective, because the house retains heat, while the internal area does not change in any way.

An important advantage is the increased ability of external walls to retain heat. Walls that are insulated from the outside cool down much more slowly than walls that are insulated from the inside.

Undoubted advantages:

1. Minimal heat loss;
2. Inside the insulation, as a rule, there is a dew point. In rare cases, it can accumulate at the outer edge of the wall;
3. The wall will never be wet;
4. The steppe maintains a certain temperature along the entire perimeter, there are no jumps;
5. The coating reliably protects the wall from seasonal and daily temperature fluctuations, it is not affected by precipitation, which is considered the main cause of its destruction.

External insulation

Internal insulation

This method considered the simplest, however, in terms of functionality it is significantly inferior to the previous one.

This manifests itself in:

• Heat losses up to 10 percent.
• dew point. It is located in the space between the inner wall and the insulation or in the insulation itself, which will undoubtedly lead to condensation beginning to accumulate and dampness appearing in the room;
• Walls are not able to retain and accumulate heat.

At the stage of performing thermal insulation indoors, it is more rational to use a vapor barrier film over a heat-insulating ball to prevent steam from entering the insulation.

The place where the thermal insulation will be adjacent to the structure must be sealed with foil adhesive tape. In this case, it is advisable to make an overlap of several centimeters.

Internal insulation

Wall construction

The wall pie should consist of:

• Thermal insulation;
• Cement board;
• Lathing;
• Brusa;
• Hydro-wind protection;
• Plasterboard sheet;
• Membrane film.

Roofing pie, despite its apparent simplicity, must be performed in accordance with certain rules:

1. The climatic zone and purpose of the house should be taken into account when calculating the thickness of the walls;
2. To choose insulation you need pay attention to good sound and heat insulation, reasonable price;
3. If the purchased thermal insulation does not have special protection against getting wet and other negative influences, it is rational to use a special film;
4. It is essential to apply the insulation correctly so that avoid cold spots where heat leakage is possible in the future;
5. The construction of the façade is carried out taking into account the requirements for the materials used.

Wall construction

Preparation for application - installing sheathing, sealing cracks, etc.

Liquid thermal insulation Apply exclusively to dry walls, which must first be cleaned of small particles of dust, white deposits of soluble salts, past coatings, and possible fungal infections.

If necessary crumbly and soft areas are removed, cracks are formed using different compositions of cement and plaster.

Also required removes laitance from concrete surfaces. This can be done mechanically or chemically.

NOTE!

To smooth out significant defects (chips and deep cracks), it is necessary to use an appropriate putty for interior or exterior work.

After all the cleaning work, you can begin installing the sheathing on the wall. Initially, using a plumb line, the rack is installed at the corners of the wall. It is worth stretching the string between them, so that in the end you see the “guitar string” - sagging in this case is unacceptable. Then the vertical posts are attached.

Lathing

Thermal insulation material should be applied to a new concrete or plastered wall only a week after it has completely dried. In this case, the permissible percentage of moisture and temperature in the room itself or outside must be taken into account.

When thermal insulation is applied to a wall that has previously been painted, First, the old paint is removed from areas of peeling and peeling. If necessary, sanding is carried out with sandpaper. Choose medium and coarse grain models.

Insulation of liquid thermal insulation from the inside - detailed installation diagram step by step

1. Work must begin with the stage of leveling the walls. The brick wall must first be treated with plaster and then primed. Each subsequent ball of paint must be applied after the previous one has dried. At the final stage, the walls are plastered.
2. Liquid thermal insulation is applied to regular paint, so anyone can do the job. For a high-quality coating, it is worth applying more than one layer of coating. After the latter has dried, you can proceed to finishing the walls.
3. Use a roller, brush or sprayer to apply the coating.
4. For work, arm yourself with a brush made of unnatural bristles, which are used for applying interior and façade paint to paint a small surface. Before applying the necessary thermal insulation material, the walls are wetted with water.

CAREFULLY!

To obtain the necessary insulating layer, it is important to direct movements only in one direction.

When applying heat-insulating material to plaster, it is recommended to use staple; the layer thickness should not exceed 1.0 mm.

• Before applying the thermal insulation material, it should be thoroughly mixed to obtain a homogeneous mass. If technical devices are used for this purpose, the rpm speed cannot be more than 250. If necessary, liquid thermal insulation is diluted with running water. Mix the resulting mass periodically during operation.
• Use a layering brush to apply, air or airless sprayer, in this case it is necessary to follow the drying technology between different layers.
• The thickness of the applied coating should be no more than half a millimeter, some manufacturers allow applying a layer of 0.8 mm to plastered, concrete, and brick surfaces. The final coating thickness is determined by thermal and technical calculations.
• After applying one ball of the material used with a thickness of no more than a millimeter, you need to wait at least a day before applying the next one. Complete drying of the finishing ball depends on their number. Temperature and air humidity also play an important role. If necessary, the drying time between layers must be increased several times. The coating will resist precipitation within 24 hours.

Vapor barrier and waterproofing

When insulating, you should pay attention to vapor barrier, otherwise the surface will very quickly become unusable. The most commonly used liquid rubber is liquid mastic.. This is an excellent vapor barrier that does not allow moisture to pass through.

Rubber should be applied in an even layer; its significant advantage is that seams do not form after use. Rubber must be applied by spray, directly on top of the thermal insulation.. The layer should not be more than a millimeter.

Vapor barrier of walls

Waterproofing protects various building structures from moisture penetration. It is easy to apply, does not require special qualifications from workers, and does not form seams.

The choice of liquid insulation remains with the owner of the house or apartment. But, in any case, when buying a material you like, you need to carefully study the characteristics (technical as well as operational) and instructions for applying the product to the selected surface.

Do-it-yourself insulation of a wall with liquid thermal insulation:

In contact with

On the eve of winter, residents of multi-storey buildings often think about additional insulation of their apartments. Today, liquid wall insulation is increasingly used to cover the facade. What is the essence of the technology and how is it better than traditional materials? Below we will try to answer these questions in more detail.

What is liquid thermal insulation

The latest development is a liquefied substance that, soon after application to the surface, forms a solid microporous layer. The large number of tiny bubbles allows the material to retain heat much better than foam or glass wool. So, 5 cm of traditional insulation can be safely replaced with 1 mm of liquid insulation. The advantages also include complete safety for humans and the environment.

Modern insulation outperforms conventional thermal insulation in terms of application, because it can be used almost everywhere:

• walls (external and external);
• ceilings, floors, roofing;
• pipes.

In this video, experts tell you how to work with liquid heat insulator.

Types of liquid insulation for walls

Modern heat insulators can be divided into groups according to different indicators. We will give the most common classification.

Liquid foam

Today the construction market offers several types of such insulation materials.

Polyurethane foam (PPU)

The material is developed on the basis of liquefied urethanes, which, under the influence of a chemical reaction, form a foamy substance, increasing in size by almost 50 times. After 24 hours, the mixture finally hardens, forming a durable, finely porous layer, reminiscent in structure of polyurethane foam. Polyurethane insulation is applied using a special spraying unit, which delivers the contents to the surface under high pressure.

Polyurethane insulation is applied using a special spraying installation

Penoizol

Penoizol differs from the previous thermal insulator in its lower price, lower density and poor thermal conductivity. This budget option is made by urethanes, which belong to the urea-formaldehyde group. In terms of efficiency, it can be compared with traditional insulation (foam or mineral wool). The material is also applied under high pressure using a spray gun. The finished volume, as a rule, does not exceed more than 30 times the original mixture.

Polynor

Another heat insulator based on heterochain polymers. Available in small cylinders. One container is enough to finish 1 square. m when applying a layer thickness of about 60 mm. Compared to other materials, Polinor is much more expensive, and therefore it is not profitable to use it for large rooms. A convenient container with a nozzle allows you to apply insulation without preliminary preparation of the material.

Warm paints

They contain ready-made additives that do not require pre-foaming.

"Corundum"

The Russian brand that produces this insulation provides a guarantee for its products for up to 15 years. The material has a uniform viscous texture with high adhesion to various surfaces. Corundum is applied with a spatula or paint brush. It can also be sprayed, but must first be diluted with water.

The manufacturer offers several variations of thermal insulation:

• "Facade";
• "Winter";
• "Anticor";
• "Fire protection";
• "Lotus";
• "Classic";
• "Waterproofing";
• "Sanitary";
• "Foundation".

"Armor"

This thermal insulation is produced by a Vologda company that has copyrights to the insulation composition. The paint has a fairly thick consistency, allowing it to adhere well to any surface. It has water-repellent properties and can also be used as a waterproofing coating. Like the previous mixture, “Bronya” is available in several versions:

• "Classic";
• "Light";
• "Standard";
• "Universal";
• "Facade";
• "Metal";
• "Wall";
• "Fire protection";
• "Volcano";
• "North";
• "Winter";
• "Anticor".

"Akterm"

The country of origin of this thermal insulator is Russia. The company produces paints intended for two types of work: insulation and waterproofing. The Akterm product line is represented by 13 formulations with different technical characteristics:

• "Concrete";
• "Metal";
• "Anticor";
• "Facade";
• "Standard";
• "North";
• "Volcano";
• "Akterm - NG paint";
• "Anti-condensation";
• "Fire protection";
• "Hydrophobizer";
• "Zinc";
• "Plast".

When using Akterm thermal paints for walls or facades, you can add different colors to them.

"Astratek"

Another Russian brand that ranks first among manufacturers of modern liquid insulation. The paint has a uniform texture, the consistency resembles a suspension. This liquefied structure allows it to be applied not only with a paint brush, but also with a sprayer. The manufacturer produces several variations of formulations:

• "Facade";
• "Metal";
• "Universal";
• "Anti-condensation".

"Corundum" "Armor" "Akterm" "Astratek"

Ecowool

The composition of this environmental material includes several components:

• recycled cellulose;
• minerals;
• boric acid;
• wood;
• waste paper

The thermal insulator is well suited for insulating floors, as well as areas of walls where condensation often forms. The ecowool market is represented by several brands:

• Greenfiber – has thermal and waterproofing properties, absorbs noise;
• Ekovilla is a heat insulator with high technical performance and a long service life;
• Termex – is characterized by increased environmental friendliness;
• “Ecowool Extra” - used mainly for residential buildings or apartments;
• “Equator” is made using European technologies, observing international standards.

Ecowool is well suited for wall insulation

Criterias of choice

The service life of the insulating layer depends on the quality of the heat insulator. Take the time to carefully examine the product, paying attention to the following points:

• the density of the mixture - the lower it is, the better the thermal insulation;
• the number of microspheres that have risen - if you look at the container through the light, the top layer should be as thick as possible;
• the presence of microscopic granules - a high-quality thermal insulator will feel slightly rough to the touch;
• uniform color - the color of the mixture should be white, without any extraneous shades.

Advantages and disadvantages of liquid thermal insulation

Opinions about modern insulation are mixed. The advantages of the compositions include the following properties:

• Possibility of application even on uneven surfaces;
• good resistance to precipitation;
• cost-effective installation;
• lack of joints;
• there is no need for complex preparatory work before application.

Liquid insulation also has disadvantages:

• the need for proper storage and transportation;
• shorter service life than traditional materials;
• high price;
• For application it is often necessary to use special devices.

Properties of liquid and traditional insulation materials

DIY application technology

Even a beginner can use liquid thermal insulator. To do this, you only need to have a general understanding of the technology.

Preparation of tools and materials

To insulate a large area, special spray units will be needed. Liquid mixtures are loaded into them, after which the air supply is opened and the output is a ready-made thermal insulation material. Such a unit can be rented or purchased (prices for devices start from 20,000 rubles). If you need to insulate a small area, it is advisable to purchase insulators in cylinders.

To work you will need the following equipment:

• perforator;
• pobedit drills;
• wooden pegs;
• liquid foam.

When working with the facade, it is better to take a partner as an assistant, who will monitor the operation of the spraying installation, and you will supply the insulation to the walls. Small areas can be handled without assistance.

Comparison of thermal conductivity of various thermal insulations

Step-by-step algorithm of work

To apply liquid insulation efficiently, the work must be done step by step:

1. Study the condition of the surface, determine its area.
2. Level the walls using construction tools and then clean them from dust.
3. Prepare a working solution of liquid foam. Do this strictly according to the instructions, bringing the mixture to the consistency of liquid cream. Test the insulator on a piece of wall before applying. If the substance is not diluted enough, dilute it gradually, in small portions.
4. Fill the paint container with the working mixture. After wetting the roller in the prepared solution, rotate to remove excess liquid. Repeat the procedure several times until the tool is evenly saturated with paint.
5. Do not press the roller too hard onto the surface, and then move it from bottom to top. This vector will allow the paint to be evenly distributed over the surface.
6. Fill the working area with liquid thermal insulation in parts, avoiding gaps. Upon completion of work, protect the wall from rain or other precipitation by covering it with polyethylene or an awning.
7. A day later, when the final polymerization of the first layer occurs, apply the paint again. This time, move the roller horizontally.
8. Leave the façade to dry for another 24 hours.

Liquid insulation for walls is a new generation of thermal insulation materials. They are more effective, environmentally friendly and easier to apply. Also, their installation does not require prior permission from regulatory authorities, since the appearance of the facade does not change.

In the vast sea of ​​all kinds of heat-insulating materials presented on the modern market, it is not easy for even professional builders to navigate.

What can we say about ordinary people who decided to insulate their home with their own hands without the involvement of specialist finishing specialists.

The fact is that each of the heat-insulating materials has its own operational features, technical characteristics and scope of application. One of these modern thermal insulator materials is liquid wall insulation.

Types of liquid insulation

The term “liquid insulation for walls” means two completely different groups:

• thermal effect paints. Designed for painting interior walls and exterior thermal insulation;
• - foamed liquid polymers (penoizol, polyurethane foam, polystyrene foam, etc.).

In addition, there is a small group of recently developed polymers, which are currently still being finalized and cannot yet be purchased in our construction supermarkets.

Therefore, there is no need to dwell in detail on these concept materials of the future in this article.

Each of the listed groups has its own technical properties and performance characteristics, as well as methods of applying them to the surfaces being treated.

It is precisely because of the fundamental differences that liquid thermal insulation for walls should be considered separately, as two different materials - paint and foam insulation.

Before choosing one or another option, you should carefully familiarize yourself with all the nuances of their use.

Thermal paint

This is a relatively new material that appeared on our market no more than a decade ago. It is used as insulation for walls inside and outside buildings.

In appearance, paint-based thermal insulation is practically no different from ordinary acrylic paint - it has a similar structure and even smell. However, thermal paints, unlike acrylic paints, are a high-tech product and have a rather complex composition.

In scientific terminology, this is not just paint, but a liquid suspension with a heat-preserving effect. It consists of the following components:

Specifications

According to manufacturers, painting liquid insulation materials have unique thermal insulation properties. Thus, according to technical tests, a layer of thermal paint of 1.1 mm can effectively replace a layer of mineral wool with a thickness of 50 mm.

This brilliant indicator is achieved due to the presence of a large number of vacuum-filled microspheres inside the thermal layer. This significantly reduces heat loss from inside the building due to convection. The brilliant color created by glass ceramics, aluminum and titanium derivatives provides additional protection by reflecting infrared radiation.

In general, the paint-based heat-insulating coating works like a reflective coating on a thermos. The consumption of the heat-insulating suspension is 1 liter per 2 sq.m., when applied with a thickness of 0.5 mm. It is applied in several layers until a thickness of 1 - 2 mm is achieved.

Comparative characteristics of liquid paint insulation, mineral wool and polystyrene foam.

Regardless of whether the walls are insulated from the outside or from the inside, it will not be possible to achieve the indicator declared by the manufacturer (1 mm layer of thermal paint = 50 mm layer of mineral wool). According to the instructions for use, it is enough to apply a heat-saving suspension to the surface with a roller or brush to dramatically warm up the interior.

As the practice of using such materials shows, painting the brick walls of a building with them can increase the temperature in the premises in winter by 1.5 - 2 degrees. That is, there is still some effect from the warm paint, but it is, of course, far from the notorious 1 mm = 50 mm.

To achieve a similar result, according to basic calculations, it will be necessary to cover the perimeter of the house with 12 - 15 layers of heat-saving suspension. And this will be simply unrealistically expensive, given the high cost of such compounds.

But despite the controversial issue of the effectiveness of heat-saving paint, it still has a number of advantages. First of all, this is the aesthetic side. As experienced finishers advise, if you have decided to paint your house, then it is better to use thermal suspension for these purposes, of course, if its cost fits into your estimate.

On the one hand, there is an excellent decorative effect, which is provided by a coating with an iridescent metallic sheen. On the other hand, there is at least some heat-saving effect, which conventional paints and varnishes lack.

Thirdly, thermal paint has anti-corrosion and antiseptic properties, so treating the internal or external surfaces of a building, as well as communication pipes and ventilation ducts with similar mixtures, will prevent the appearance of fungus, mold and corrosion on them.

A significant advantage is the water-repellent quality of the paint, which allows you to additionally create a layer of waterproofing for internal or external wall surfaces. The convenience of using thermal suspensions for insulating communication pipes in hard-to-reach places is undeniable. The ease of application makes this method of thermal insulation the most successful.

Choosing the right thermal paint

Since thermal paint has a considerable price, you should be able to choose the right quality product. To do this, you should know a few nuances.

1. The lower the density of the coloring composition, the higher its thermal insulation properties. Typically, a 10-liter bucket of suspension should weigh no more than 6.5 kg. Otherwise, there is a high probability that the expensive composition was diluted with a simple one, worsening its technical properties.
2. Lift the bucket and look through it at the light. Lightweight microsphere fillers should rise to the top, creating a layer of metallic color at the top. The thicker this layer, the higher the quality of the suspension.
3. If, after stirring high-quality paint, you stretch a drop of it between your fingers, you can feel the presence of a large number of microspheres: the surface will not be smooth, but rough.

Application method

Liquid insulation is nothing complicated.

It is produced in several stages and is completely similar to the work of painting surfaces with conventional paints and varnishes.

When purchasing a thermal composition, it should be taken into account that the surface will have to be treated more than once. Depending on the climate zone in which the home is located, it may be necessary to apply from 2 to 5 layers of paint.

The whole process looks like this step by step:

1. You should measure the area of ​​the surface to be painted and purchase the required amount of thermal protective suspension.
2. Preparing the surface for applying paint - removing dust and dirt, filling cracks and seams, treating with a primer composition.
3. Before use, the paint should be thoroughly mixed with a mixer attachment to evenly distribute the spherical filler granules throughout the entire volume.
4. Apply thermal paint to the surface using a spray gun or roller. We paint the seams and corners with a paint brush.
5. After the first layer has dried, apply the second layer, etc. For more information about thermal compositions, watch this video:

Until it dries completely, that is, at least a day, the painted wall should not be exposed to heavy rain. It can wash out light micro-grain fillers from paint, which will turn expensive thermal insulation into ordinary acrylic paint.

Foamed polymers

Other liquid thermal insulation is foamed polymers - polyurethane, etc.

Advantages and disadvantages of foam insulation

Unlike solid boards, liquid polymers provide an increased level of thermal insulation. The fact is that when installing sheets of the same foam plastic, it is very difficult to achieve their tight fit to the wall surface. In any case, over time, a gap forms between them, which significantly reduces the effectiveness of thermal protection.

When liquid foam is applied to the surface being treated, it adheres tightly to it without forming any gaps. Thanks to the excellent adhesion of foam compounds, they are firmly held on any surface - wood and walls, metal pipes and concrete floor slabs.

In addition, for uniform and durable application of foam there is no need to level, putty or otherwise prepare the walls. If foam insulation is applied to the façade parts of a building, after hardening it can be subjected to further decorative processing. Trim off excess foam and foam, and then treat it with a leveling putty compound. The service life of such thermal insulation can be about 50 - 70 years.

Among the disadvantages of these thermal insulation materials, it is worth pointing out their low environmental friendliness. When heated, polymers begin to release volatile chemicals, and when burned, they begin to release large amounts of acrid smoke.

The fire resistance of foam insulation is simply zero. Not only can it not create reliable protection against fire, but it itself actively supports combustion, contributing to the spread of fire.

Another disadvantage is that surfaces treated with foam no longer allow air to pass through them. As a result, the natural gas and steam exchange indoors is disrupted. To restore it, it is necessary to install an efficient ventilation system.

The only exception here is penoizol - it does not support combustion under normal conditions and can serve as fire protection.

Compound

Foam insulation is produced using a number of complex components. They include:

1. Urea-formaldehyde resin.
2. Orthophosphoric acid.
3. Foaming chemical components.
4. Water.

Due to the fact that toxic substances are used as components, when working on spraying foam insulation, you should use protective clothing, including respirators, goggles and gloves.

Application method

Foamed polymers are applied to the surfaces being processed using special devices connected either to an air compressor or to compressed air cylinders. For more information about the characteristics of the material and its spraying, see this video:

All chemical reagents are loaded into the mixer hopper, and water is also added there. After this, the stirrer hatch is hermetically closed. As a result of a chemical reaction, foam begins to be produced inside it, which is supplied outward under pressure from a special nozzle.

When insulating the walls of houses, two different technologies can be used:

• external insulation;
• internal wall insulation.

External insulation is carried out by spraying polystyrene foam or other polymer onto the external walls of the building. This treatment is carried out immediately before finishing the house. After drying, the foam forms such a strong adhesion to the wall that it serves as a solid base for applying subsequent layers of decorative finishing. Such a surface can be plastered, puttied, or simply covered with siding, glass-magnesium or other finishing material.

The in-wall insulation system is used directly when laying brick walls. In this case, channels 1 - 1.5 m long and half a brick wide are left inside the masonry. After the walls are raised by 1-1.5 m, the wells are filled with foamed polymer.

After this, the masonry rises to the same height, and the process of filling the wells is repeated. This method is used if the walls of the house are constructed from facing bricks, and external insulation is not provided for by the project. For an example of insulating a house in 1 day, see this video:

After a detailed consideration of all the nuances and features of both materials, you can make the right choice in favor of one of them. It all depends on the design features of the building, the level of thermal protection required, the requirements and financial capabilities of the home owner.
