Glue for insulation works. Glue for gluing insulation What kind of glue to glue insulation

Various thermal insulation materials, such as mineral wool or polystyrene foam boards, are widely used to insulate buildings. But in order to fix them, it is necessary to ensure the maximum adhesion density with the insulated surface. Given the structure of these materials, the use of traditional fasteners such as dish-shaped dowels is inefficient, since they are not able to completely eliminate the movement of air under the insulation. That is, the meaning of the work is lost.

The most optimal solution is to buy glue for gluing insulation. These are special compounds that can not only provide reliable mechanical adhesion, but also improve the thermal insulation characteristics of the coating.

What glue is needed for gluing insulation?

When choosing a particular composition, it is desirable to pay attention to the following factors.

• Appointment.

Depending on the insulation you use, you should buy the appropriate type of glue. In particular, mixtures for expanded polystyrene cannot be used for gluing mineral wool and vice versa.

• Foundation type.

For solid walls (brick or concrete), fully curing mineral compounds are best, while for wood, a more elastic adhesive is needed. It is also important to take into account the mobility of the supporting structure and its evenness.

• Secondary functions.

Adhesive for gluing insulation may additionally have reinforcing properties. Due to the addition of special plasticizers, it also plays the role of putty.

• Frost resistance.

For insulation of facades at low temperatures, adhesive compositions with antifreeze additives should be used. They retain their properties down to -10°C.

• Vapor permeability.

A good adhesive should resist condensation and maintain a healthy "breathable" indoor climate.

• Strengthening speed.

The timing of the installation of insulation depends on this characteristic.

You can order glue for gluing insulation of any type in the Bau-store online store. Our catalog contains only high-quality building materials from the world's leading manufacturers at the most attractive prices. For each composition, its main characteristics are indicated: glue consumption for gluing insulation, performance properties, drying time, etc. Discounts are provided to wholesale buyers.

The efficiency of the work carried out depends on the quality of the installation of the insulation. Now the method of mounting insulation material with glue prevails. And therefore, it is the quality of the adhesive mixture and the type of fasteners used that play an important role in warming.

But many repair beginners make mistakes when choosing an adhesive mixture and during its use, as a result of not following the instructions for using adhesive for thermal insulation. Due to such errors, costs increase, the quality of insulation suffers and the service life decreases.

Why is it necessary to use special glue

Why glue heat-insulating material, if you can simply attach it with dowels? When fixing with dowels, it is impossible to achieve fixing of the insulation without movement and it is impossible to completely prevent the movement of air under the heat-insulating material. Namely, these moments reduce the effectiveness of insulation.

It is better to use factory-made adhesive mixtures, and not to prepare glue for thermal insulation with your own hands. After all, manufacturers have taken into account many years of experience and added special components to them, which not only do not worsen the thermal insulation properties of insulation, but even improve them.

The use of such an adhesive makes it possible to use it in strong winds and high humidity, increases the resistance of the material to temperature changes. Also, the use of such compositions allows you to save on insulation.

What glue to choose?

In order to choose an adhesive, you must first decide on the following points:

• type of insulation used;
• surface to be mounted.

By visiting any online store of building materials and selecting the appropriate section, you will see a lot of photos of glue for insulation, because they are presented everywhere in a huge assortment.

As a rule, dense plates of heat-insulating material are installed by the adhesive method of installation. This group includes plates made of mineral wool and polystyrene.

For them, it is necessary to select the appropriate glue, otherwise, for example, the vapor permeability of mineral wool can be violated. Accordingly, for such a heater it is unsuitable to use a composition intended for fixing polystyrene.

Accordingly, two types of glue are distinguished:

• for foam and EPPS;
• for mineral wool.

Depending on the type of base on which the insulation adhesive will be installed, it is necessary to select the type of adhesive with specific characteristics. For example, for concrete it is necessary to use glue with an absolutely hardening composition, and for wood - with the addition of components that increase elasticity.

It is also worth paying attention to the evenness of the surface - this affects the thickness of the layer. And for this parameter there are strict restrictions from manufacturers. It is also necessary to consider whether various movements, such as vibrations, etc. are possible.

Dry adhesive mixtures according to the type of purpose are divided into:

• mixtures only for gluing plates;
• universal reinforcing mixtures.

As the name implies, the first type is used only to fix the plates, and the second one also creates a reinforcing layer on the surface.

Composition classification

According to the method of application and composition, three types are distinguished:

• Polyurethane bottles.
• Dispersion in buckets.
• Dry mineral mix.

The polyurethane mixture is under pressure in a cylinder and looks like polyurethane foam. It is easy to use, but has a relatively high cost.

This type of adhesive is characterized by the best coupling characteristics with various surfaces. It is used for internal and external insulation with foam or extruded polystyrene foam.

Advantages and features:

• saving time during work;
• high adhesion;
• can be used immediately after purchase;
• excellent thermal insulation properties;
• it is possible to carry out installation both at low and elevated temperatures, and at high humidity;
• there are no harmful components in the composition;
• water resistance.

Dispersion in buckets is specially designed for fixing insulation to a variety of wooden surfaces. Due to the presence of organic binders in the structure, it is an environmentally friendly material. Can only be used to fix foam or extruded polystyrene foam.

Advantages and features:

• high adhesion with wood materials;
• high elasticity;
• simplicity and versatility in use;
• temperature range of application from +5 to +30 degrees;
• consumption of glue for thermal insulation is approximately 1 bucket (25 kg) per 16.5 sq.m. insulated surface;
• the thermal conductivity coefficient is 0.6 W / m * K.

Dry mineral adhesives are used to fix foam or mineral wool. Most of them have reinforcing properties.

Advantages and features:

• consumption 4-5 kg ​​per 1 sq.m. when gluing, and 5-6 kg per 1 sq.m. when reinforcing;
• have a high level of adhesion with mineral surfaces;
• medium elasticity;
• the composition contains reinforcing components;
• has shock-resistant characteristics;
• has vapor permeability. moisture and frost resistance
• environmentally friendly.

Important and general technical characteristics that you need to pay attention to when choosing:

• Plastic;
• Vapor permeability;
• Frost resistance;
• The service life of the finished solution;
• Fast fixing;
• Temperature range for application;
• The layer thickness of the applied layer.

Photo of glue for thermal insulation

Thermal insulation is not just an additional measure to maintain comfort in the house and a means of saving individual structures, but a regulatory requirement. Therefore, the organization of insulation should be approached responsibly and with knowledge of the nuances of this event. There is a wide range of materials for thermal insulation, but most of them are combined with adhesive mounting technique. An alternative way is fixing on fasteners, but this is rather an exception to the rule. At the same time, the adhesive for insulation itself is presented in a huge assortment, which may well complicate the choice in the eyes of a beginner.

Features of adhesive for thermal insulation

Such compositions have unique combinations of physical and operational properties even against the background of building adhesive mixtures. This is largely due to the fact that the function of this tool converges with the tasks that the insulation itself performs. In particular, such an adhesive should provide, albeit at a minimum, the same thermal insulation, vapor permeability, protection against moisture and at the same time be mechanically resistant. As for the immediate task of mechanical retention of the target material, the adhesion provided by special modifiers is responsible for it.

At the same time, the adhesive for insulation is environmentally friendly. Since insulation boards and roll materials are often installed directly in residential areas, this requirement is one of the key ones. The only exceptions are facade products, but in this segment, manufacturers also strive to minimize the content of harmful components, although the general requirements for compositions for outdoor use are much higher.

Tools for working with foam

Under the general name of polystyrene, a whole group of materials is hidden, which also includes polystyrene directly. The peculiarity of gluing such panels is the need to provide high adhesive force. The form factor of tile insulation itself presents difficulties in terms of performing an adhesive function, so the main focus in the choice is on this property. The laying surface, especially metal, can also complicate the adhesive's ability to adhere. In this case, formulations that include gasoline, acetone and active solvents should be discarded. These components will not only reduce adhesion, but can also adversely affect the condition of the foam itself.

And what to glue the insulation on? In addition to high adhesive strength, physical durability, stable hardening, moisture resistance and non-toxicity should be taken into account in the composition.

Means for mineral wool

Mineral wool, in some versions, is also a tile material, but the fibrous structure as such still increases adhesion, unlike polystyrene. And yet you should rely on the quality of the adhesive, which will ensure its strength and reliability. This will help the structure to cope with dynamic loads, which are especially dangerous for. Therefore, a mechanically resistant and solid adhesive for insulation is selected.

Alternative bonding methods

As an alternative solution, you can offer tools such as PVA, "liquid" nails and mounting foam. The first option may well replace specialized tools when it comes to gluing thin panels to an even and adhesively favorable base in the room. Mounting foam will provide impeccable hitch strength. If mechanical reliability is at the forefront, then this option should be preferred. But it should also be borne in mind that the mounting foam will cause a lot of trouble if you need to dismantle the insulator. "Liquid" nails are also focused on creating a strong bond, but this glue for gluing insulation can only be used outside residential premises. This is due precisely to the content of toxically harmful components.

Conclusion

Practice shows that the highest quality insulating coatings are formed under conditions when all components of the structure have approximately the same technical and operational properties. Following this principle, we can conclude that polyurethane compounds with polymer additives are more suitable for expanded polystyrene.

What, in this case, should be the glue for the mineral wool insulation? It is desirable for this material to choose environmentally friendly dry mixes in which the content of synthetic elements is minimized. And here it is worth distributing the directions for using the two combinations. So, the use of polystyrene will be the most beneficial as part of the facade finish, since it itself is not ideal in terms of environmental friendliness. And vice versa, mineral wool can be used in interior decoration of premises, regardless of their functional purpose.

Most often today, the “light-wet” method of installing heat-insulating materials is used. Its essence lies in the fact that special adhesive mixtures are used to fix the insulation on the planes. The quality and the correct choice of glue directly affects the efficiency of the work carried out, it depends on what kind of glue mixture and what fasteners are used, how tightly and reliably the insulation will adhere to the wall.

However, when choosing an adhesive, as well as when using it, inexperienced craftsmen make many mistakes, which increase the cost of insulation, or significantly reduce the efficiency and durability of the layers. It comes to the point that ordinary tile adhesive is used here. Before proceeding with the purchase, the homeowner needs to clarify some points.

Benefits of using a specialized adhesive

Why do they glue insulation at all, because it would be possible just to make it qualitatively? Dish-shaped dowels will never provide one hundred percent reliable fastening without movement, which is required for the wet method of facade insulation (otherwise cracks will appear). They are only an additional fixation element. In addition, with the help of glue, it is possible to completely eliminate the possibility of air movement under the insulation, which can cool the wall as if the insulation had not been carried out.

Why is factory out of competition? Since this is always a ready-made composition, the maximum that the user needs to do is to properly close it with water. You don't have to reinvent the wheel. Today, adhesive compositions for thermal insulation materials contain a whole range of special additives, the need for which has been studied for years. The result is an adhesive capable of maintaining and even enhancing the thermal insulation properties of materials. Its use ensures reliable adhesion of the insulation to the plane, while the service life of the insulation layers is significantly increased.

When using such adhesive mixtures, thermal insulation materials acquire properties that help withstand adverse weather phenomena, while they can be used in high humidity and strong winds, and are also able to withstand both very high and fairly low temperatures. Moreover, these properties are guaranteed and repeatable.

In addition, the use of special glue allows you to reduce costs when arranging insulation. When installing thermal insulation, the consumption of a modern technological adhesive mixture will be much less, since it does not need to be applied over the entire area of ​​​​insulation plates. And given some of the technical features of the new adhesives, their use will save money in subsequent operations.

Which glue is better: choose

By appointment

If we do not take into account the issues of price and brand popularity, then the developer for a competent configuration must decide on two main issues:

• What insulation will be used?
• On what basis will the adhesive installation be carried out?

And then you can already consider the individual technical characteristics of similar products.

Manufacturers today offer customers a fairly large selection of various adhesive mixtures designed for mounting a wide variety of thermal insulation materials. Naturally, dense slabs of mineral wool and polystyrene (polystyrene and XPS) are mainly installed by the adhesive method. These two types of insulation differ in structure and physical properties, therefore, the adhesive for their installation and the manufacture of the reinforcing layer must have certain characteristics. For example, in order not to disturb the vapor permeability of a wool insulation layer. This means that in systems with mineral wool insulation, you cannot use a mixture intended for expanded polystyrene. So, there are two types of adhesives:

• for foam and EPPS;
• for mineral wool.

It is very important to choose the right type of glue, and in most cases it depends on the type of base. Obviously, a completely hardening mineral composition is well suited for a brick, block, concrete wall, but, for example, for wooden walls, a completely different, elastic one is needed. It is also worth considering how even the base is, that is, what layers of glue will have to be applied to get a good plane, because there are strict restrictions from manufacturers on this score. It is important to evaluate the possibility of movement of the supporting structure, if bending loads, fluctuations in geometric dimensions, vibrations are possible, then elastic elastic adhesive compositions would be the best option.

Basically, dry mineral adhesive mixtures sold in bags are divided into the following subgroups according to their intended purpose:

• mixtures only for gluing boards;
• universal reinforcing compositions.

They differ from each other in that the former are intended exclusively for gluing insulation, but using reinforcing glue, you can not only glue the plates, but also create a reinforcing layer on their surface. The chemical composition of these adhesives is almost the same, the main difference is that the reinforcing adhesive contains additives that increase plasticity and facilitate thin-layer application. In conventional adhesives, there is no such plasticizer, and therefore the price is slightly lower for them. If the description of the adhesive does not indicate that it is intended for reinforcement, then it can only be used for mounting plates. Some companies offer a special mixture for the installation of reinforcing fiberglass, they are positioned as "adhesive putty".

Composition

According to the method of application, composition and performance, the adhesive is classified into three types:

1. Polyurethane in cylinders.
2. Dispersion in buckets.
3. Dry mineral mix in bags.

Naturally, each type differs in working properties, areas of use and price.

Polyurethane adhesive is packaged in cylinders under pressure and in appearance resembles mounting foam. Such an adhesive composition is characterized by maximum ease of use, but its price is quite high. This type of glue shows the best adhesion to most substrates. It is ideal for insulating concrete walls, surfaces treated with mineral plasters. With its help, the insulation perfectly adheres to plywood and OSB boards, to massive wooden structures, to metal cladding, such as profiled sheets. Polyurethane adhesive is intended for insulation using polystyrene foam or extruded polystyrene foam, it is used for interior and exterior work, both in the construction of new houses and in the thermal insulation of old buildings. Polyurethane adhesive is chosen due to a number of consumer and technical advantages:

• the terms of work on insulation are reduced significantly;
• high adhesion to all bases;
• full readiness for use;
• excellent thermal insulation properties;
• allows installation at low temperatures, in heat, as well as high humidity;
• the absence of harmful substances in the composition;
• absolute water resistance.

The dispersion in buckets is specially designed for gluing insulation to various wooden substrates. This adhesive mixture contains organic binders in its composition, therefore it is considered environmentally friendly. The dispersion is easy to use (sold ready for use), it can be used both outside and inside. This mixture is only suitable for gluing polystyrene foam and EPS (extruded polystyrene foam). It cannot be used to create a reinforced waterproof layer, as well as for puttying. Features of the dispersion adhesive mixture are as follows:

• high adhesion to wood and derived materials;
• increased elasticity;
• versatility and ease of use;
• it can be used at air and base temperatures from plus 5 to plus 30 degrees;
• one bucket (25 kg) is enough to insulate a surface of 16.5 sq.m.;
• the thermal conductivity coefficient is 0.6 W/m*K.

Dry mineral mixtures are designed for mounting cotton wool or polystyrene foam on mineral bases. Many of them are also suitable for creating a reinforcing layer. Such dry glue must be mixed with water before use. The average consumption of dry mixes is: for gluing heat-insulating materials - 4-5 kg ​​per sq.m., for reinforcement - 5-6 kg per sq.m.

Dry glue for insulation has the following advantages:

• good adhesion to basic mineral substrates;
• moderate elasticity;
• content in the composition of reinforcing microfibers;
• impact resistance;
• vapor permeability;
• frost and moisture resistance;
• environmental Safety.

Other working properties

All adhesive compositions for thermal insulation materials are characterized by some common consumer properties that you should pay attention to:

• Plasticity - the composition of foam and mineral wool adhesives includes special plasticizers and modified additives that make these adhesive mixtures very convenient to apply.
• Vapor permeability - a good adhesive for insulation does not condense moisture, but contributes to the creation of a breathable structure, without violating the microclimate of the premises and extending the life of the walls.
• Frost resistance - all adhesive compositions for facade insulation must retain their technological properties even at significant sub-zero air temperatures.
• The viability of the finished solution - dry glue mixed with water retains all its functional features for 1.5-3 hours.
• Fast curing - after gluing the insulation, the glue hardens quickly enough, which significantly reduces the installation time of thermal insulation, and, therefore, the total cost of work.
• The breadth of the temperature regime of application - there are adhesives on sale that can be used at fairly low temperatures up to minus 10 degrees.
• Different possible thicknesses of the applied layer - the adhesive for insulation can be applied in a thin layer, and can also be used to level the insulated planes, while making sufficiently thick layers, which will determine the final cost of thermal insulation of the building.

How to use adhesive for insulation

1. Before starting installation, make sure that the base is solid, well cleaned of contaminants that impair adhesion. Crumbling fragile areas and flaking pieces must be removed without fail.

2. It is possible to insulate brickwork and bases plastered with mineral compounds only after they reach the “age” of 28 days; before insulating monolithic concrete, it must stand for at least three months.

3. Old brickwork or a wall that has been plastered for a long time should be properly prepared for thermal insulation - cleaned of dust and other contaminants, rinsed with water under pressure, and dried well. Highly absorbent bases (walls made of silicate or aerated concrete blocks) must be treated with a primer before installing the insulation on the adhesive.

4. To evaluate the bearing capacity of the surface to be insulated and the adhesion of the adhesive to it, it is necessary to conduct a test. To do this, pieces of foam plastic 10x10 cm in size are glued in several places, and after three days they are torn off. Adhesion is considered good if the pieces come off along the Styrofoam.

5. If the insulation boards have irregularities of more than 2 mm, for example, at the joints, they should be carefully sanded with emery. The surface of mineral wool slabs is swept with a brush, removing dust, free mineral fibers.

6. Dry adhesive mixtures are prepared by first mixing them with water at a temperature of 15 to 20 degrees. The amount of water depends on the manufacturer's recommendations, as well as on the application conditions. When diluted, the dry mixture is added to the water gradually, while mixing thoroughly so that lumps do not form. It is best to stir the adhesive mixture with a construction mixer or a drill with a special nozzle. After obtaining a homogeneous solution of the desired density, a five-minute technological pause should be maintained for the maturation of the adhesive, and then mixed again.

7. Glue is applied to the insulation boards in different ways - it depends on how even the base is. If, when checking with a two-meter level, the deviations are 5-10 mm, the solution is applied with a trowel along the contour of the plate - the width of the strip is 3-4 cm, the indent from the edge is 2-3 cm. Several spots (5-8 pieces) are also made in the middle of the plate - diameter spots of 8-10 cm. The strips of the adhesive mixture along the contour should be with breaks so that air jams do not form, their thickness should be about 20 mm. If the level shows deviations of less than 5 mm, the adhesive is applied using a steel notched trowel (teeth size 10-12 mm) to the entire plate, while retreating from its edge by 2-3 cm. Before applying the solution to the mineral wool board, it is recommended to prime it completely a thin layer of the same glue. Polyurethane adhesive from cylinders is applied using a mounting gun, before that the cylinder is thoroughly shaken. Application is carried out along the perimeter (indentation from the edge of the slab should be about 2 cm) and through the center of the slab in one strip.

8. Immediately after applying the solution, the slab is applied to the base and pressed well by hitting / pressing down with a long float. If the adhesive is applied correctly, the area of ​​adhesive contact after pressing the board should be more than 40% of the area of ​​the mounting plane of the insulation board. The gap between the plates should be no more than 2 mm. Larger gaps should be filled with styrofoam scraps or polyurethane foam.

9. Additional fastening with dowels is carried out only after 3 days after gluing the heat-insulating material, then a reinforced layer is applied. It should be noted that the influence of glue on the quality of thermal insulation should not be overestimated. When insulating buildings using the wet method, it is important to correctly carry out the entire range of work, choosing the right primer compositions, adhesive solution, type of insulation, and surface finishing material. Only in this case, you can get an excellent end result.

Specialization: master of interior and exterior decoration (plaster, putty, tile, drywall, wall paneling, laminate, and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, repairs in an apartment or house were done on a turnkey basis with all the necessary types of work.

Before you buy facade adhesive for insulation, you need to decide what material you will isolate the walls with. This can be a ready-made finishing material, such as EXPLETE EPS board (extruded polystyrene foam) or foam, which is covered with decorative plaster.

In all this we have to figure it out, and I will also talk about the materials and the place of insulation.

Facade insulation: outside or inside

And yet, why do most craftsmen offer facade insulation, and not internal insulation, because it is much more convenient to work from the inside, especially when a new building is being erected? I am not talking about this because there is a certain instruction that obliges you to install thermal insulation from the outside, but because this is actually common sense.

Although in some situations, internal insulation is the only possible, and therefore the most acceptable.

Pay attention to the figure above - it shows the zone of formation of the dew point. In other words, this is condensate at different positions of thermal insulation and without it.

As you understand, condensation forms when warm air collides with a cold surface. And since the atmosphere is saturated with moisture, under certain conditions it turns from steam into water, that is, into dew drops.

If the insulation is from the inside, then the dew point falls either on the gap between the wall and the insulator, or on the body of the wall. But both one and the other are bad, since dampness accumulates on the surface, and conditions are created in the wall itself for its destruction.

In cases where the insulation is outside, the wall does not cool down to the dew point. Therefore, if you choose the thickness of the insulation in accordance with the coefficient of your region, then this zone will shift to the insulation itself, which is not at all dangerous.

I hope I have convincingly made it clear to you, dear readers, that it makes more sense to insulate rooms from the outside, and not from the inside.

Glue and its purpose

The adhesive can be universal, but it can also be designed specifically for a specific material - for foam, extruded polystyrene foam, mineral basalt wool and reinforcing mesh. When choosing a composition, pay attention to the packaging - there are always instructions for use and instructions for preparation.

Adhesive application table

One of the most expensive trains - BAUMIT Star Contact

In the table, not for each adhesive in the column "reinforcing mesh" there is a +, indicating that such an adhesive can be used to fix the reinforcement, since this is not indicated by the manufacturer. But from personal experience, I can say that almost all mixtures are able to hold such a mesh well, and you will not need to choose another brand for this.
The cost of a particular composition depends on its scope, but BAUMIT StarKontakt usually has the highest price (in the spring of 2016 it was about $6.3 - $6.5).

Facade insulation

Before gluing polystyrene foam, extruded polystyrene foam, basalt wool or even self-adhesive insulation, you need to prepare the surface. The fact is that any glue needs adhesion (this is the essence of the process), but if there is dust or loose plaster on the surface, then adhesion will turn into cohesion.

In addition, you will need to close up the cracks and in no case proceed with insulation if the house is in an emergency condition (subsidence, cracking, and so on) - all your work will be in vain.

To correctly determine the insulation power, you need to find out the coefficient for your region and for the materials used.

Styrofoam and extruded polystyrene foam are glued to the wall according to the principle: the working side of the panel is partially or completely smeared and pressed against the object of insulation. This measure must not be neglected - additional fastening (fungi-dowels) will not be enough.

These are not empty words. I saw with my own eyes how a strong wind “cut” a nine-story building within 3 minutes, as the finishers neglected the glue, or rather, did not use it enough.

At first, only one corner panel at the level of the eighth floor was torn off by the wind, but then strong gusts of wind crept up to the rest. Since there were many gaps between the foam and the wall, a strong air flow began to make its way into these gaps and tear off the insulation.

Only the first floor and partially the second did not suffer, since closer to the ground the wind force was less - it was extinguished by the surrounding buildings and trees.

Additional fastening - fungus-dowel

After you glue the panels, fix them additionally with special dowels - they have a hat made in the form of a mushroom. A hole is drilled in the wall with a puncher, then a dowel is inserted and a nail from the kit is hammered into it. The immersion depth in the wall must be at least 5s, so choose the appropriate length of the mushroom.

After installing the foam or extrusion, you will need a front finish (most often, this is decorative plaster) and for this you need to reinforce the insulation. Apply glue to the surface with a notched trowel, straighten and attach the mesh there.

After that, press it with a trowel or grater. After drying, you can start applying decorative plaster.

For mineral wool, additional fasteners such as dowels are rarely installed, so the glue must be applied with a comb to the entire surface, as shown in the photo above.

If you still use dowel fungi for basalt wool, then the mixture can also be applied pointwise to it. The fact is that cotton wool is used for frame finishing, therefore, it will not be subject to heavy loads, as it is protected from the wind.

It should be said that insulated glued beams or a solid wooden profile need the same adhesives.

9 myths about insulation

The layman often has an erroneous belief in the following:

1. Extruded polystyrene foam is more reliable than polystyrene? But in terms of thermal conductivity, they are very similar. So, the usual PSB-35 transmits infrared radiation only 0.002 units more intense than the extruded PSB-35. In addition, the extruder is deformed under the influence of high temperatures and is much more expensive.
2. Mineral wool is cheaper? Yes, but this is only for roll material, and plates will cost you more than foam. In addition, the insulating power of mineral wool is less than that of PSB.

1. PSB does not allow the walls to "breathe"? This definition does not fall under any GOSTs and SNiPs - it's just a fear of education. But even vinyl wallpapers do not let steam through, so in this case the issue should be resolved not at the level of insulation, but at the level of the room ventilation device.
2. A warm facade does not increase the temperature in the room? This is certainly true, but it retains about 30% of the microclimate compared to a conventional wall. In fact, you will not heat the street.
3. Styrofoam can catch fire? But the wood from which houses are built also burns, and the ignition temperature of PSB is 491 ° C, while paper has 230 ° C, and wood has 260 ° C, that is, the anti-flammability properties of polystyrene foam are higher by 2.1 and 1, 8 times respectively.

1. PSB has a low service life? I wouldn't say so! Given the fact that it began to be produced only in the 50s, it was not possible to test this in practice. But at the same time, cyclic tests were carried out with a change in humidity and a temperature difference of ± 40 ° C - the results showed 80 conventional years, you see, this is a lot.
2. PSB does not comply with environmental regulations and is therefore dangerous? However, it is completely non-toxic in use. The danger arises only when ignited - it melts, releasing toxic smoke, however, like other building materials made of plastic.
3. The second layer of plaster is optional - enough paint? Of course, the paint protects from atmospheric precipitation and to some extent from ultraviolet radiation and temperature changes, but this is not enough. Decorative plaster in the form of a bark beetle or fur coat significantly increases the life of the insulation. That is, if we take 80 years for cyclic tests on an open SSB, then with additional protection this period will increase.
4. The type of material does not matter? This statement is not at all true, and manufacturers often hide the negative parameters of the insulation for their own benefit.

• firstly, the type of material, as well as its density, determine the thermal insulation power or the ability to pass cold;
• secondly, what you will use must comply with the State Standards for environmental and fire safety requirements;
• therefore, when buying a product, ask for a certificate, and if there is none, then there is a possibility that you are being offered low quality, and possibly even unhealthy material.

Conclusion

I assure you, you can always make the insulation of the facade of your own house with your own hands without the involvement of specialists, but this requires certain skills and compliance with the requirements of the product manufacturer. But the skills are in the ability to hold a trowel and a spatula in your hands.

And if you have at least a little practice in finishing work, then you can easily cope with thermal insulation. In addition, the video in this article will help you learn the topic.

Perhaps you have any ideas, then join the discussion and ask questions.
