Insulation of the walls of a brick house from the outside with foam. We carry out insulation of the outer walls of a brick house.

Brick is durable and non-combustible material, it can withstand high loads and is used in the construction of buildings of various storeys. The main disadvantage of such a house is the high thermal conductivity of the walls. The problem can be solved by increasing the thickness brickwork or by insulating the building from the outside.

Insulation of brick walls is divided into three types: external, internal and intra-wall. The latter option involves the construction of a building with well masonry and the placement of a heat insulator at the construction stage.

Internal insulation takes away the useful area of \u200b\u200bthe premises, it provokes dampness of the walls and is not effective enough. Its advantage is the ability to complete the work at any convenient time and the low cost of materials. If you have a choice, you should give preference to external thermal insulation.

Among its advantages:

• The walls are protected from external influences, so they will last a long time.
• Significant reduction in heating costs.
• The ability to create the architectural design of the house to your liking.
• Lack of moisture, mold and mildew on the surface of the walls.

The main characteristics of thermal insulation materials

For the protection of brick walls to be reliable and durable, the materials used must have characteristics that allow them to withstand precipitation, wind, frost and heat.

• Water absorption coefficient is a product characteristic that shows how much moisture it can absorb. It is better to choose a material with a low rate.
• The thermal conductivity coefficient is the main criterion in the study of insulation. It shows the amount of heated air lost per hour per square meter. m of material having a thickness of 1 m. This indicator is guided by when choosing the thickness of the insulation layer. The best products for this criterion are foam and mineral wool.
• Flammability - determines how dangerous the material is in a fire. Products are divided into four cash registers according to this characteristic, it is better to give preference to G1, which go out without open fire. Expanded polystyrene boards are susceptible to fire, when using them for cladding, choose with the marking "C", which means self-extinguishing.
• Density determines the amount of additional weight per structure - the lower the indicator, the lighter the material.
• The sound insulation level indicates the possibilities of reducing the penetrating noise. All popular heat insulators possess this quality to a sufficient extent.
• Environmental friendliness - the criterion determines the safety of the insulation for health. For exterior decoration it is not decisive, but natural materials preferable to synthetic ones.
• The complexity of installation - if the work is done by hand, you must choose a simple and understandable technology for laying thermal insulation.

The list of popular materials for cladding a house outside includes a few products:

• styrofoam;
• extruded polystyrene foam;
• mineral wool;
• warm plaster.

They have a different composition, cost and installation features. Let's consider each material in detail.

Polyfoam - plates made of expanded polystyrene, which are cells with gas. This structure provides a low thermal conductivity of 0.032-0.039, good sound insulation and light weight. The density of the foam is 35-50 kg / m3, the recommended layer thickness is 10 cm. The material is capable of absorbing moisture, therefore it requires waterproofing. The disadvantage of insulation is flammability, vapor permeability and sensitivity to light.

Extruded polystyrene foam - the product has the properties of foam, but in an improved version. The material does not absorb water, it is more durable and easy to process, its thermal conductivity is 0.028-0.032. The cost of extruded polystyrene foam boards is higher than other materials for thermal insulation.

Mineral wool is one of the best heaters, it does not burn, is safe, has a low density - 35-125 kg / m3. The raw materials for the material are glass, stone and slag. Air voids of 10-15 cm remain between the fibers, due to which the mineral wool has a thermal conductivity of 0.04-0.045, absorbs noise well and passes steam. For effective protection, a layer of 10-15 cm is needed.

The product is produced in the form of rolls, mats and slabs. Basalt wool in a slab version is characterized by resistance to deformation and increased density - 75-150 kg / m3. the material fits easily into the frame and does not cause problems during installation. The only drawback of mineral wool is its high water absorption, which requires mandatory waterproofing. Insulation is affordable, which contributes to its popularity.

Warm plaster is a dry mixture of cement, lime, plasticizers and additives from expanded polystyrene granules, expanded clay, perlite. The material is somewhat inferior in terms of thermal insulation - 0.06-0.065, but it has many advantages: it does not burn, has vapor permeability, is resistant to moisture and microorganisms, and insulates sound well. The plaster has a significant density of 200-350 kg / m3, therefore it puts additional stress on the foundation. The maximum insulation thickness is 5 cm.

Talking about how to insulate a brick house from the outside, one should not miss the opportunity to finish with thermal panels. This material is characterized by a low thermal conductivity coefficient of 0.025 with a small thickness of 60-100 mm. The basis of the product is polyurethane foam, the decorative part is made of ceramic tiles... The material is resistant to frost and moisture, quickly installed and does not require additional finishing.

Mineral wool thermal insulation technology

Warming brick house is performed in two ways:

• creation of a ventilated facade;
• "Wet facade", gluing boards to walls.

Mineral wool is optimal for the first method, which involves the creation of a crate and a multi-layer cake with steam and waterproofing.

1. A crate made of timber treated with an antiseptic composition or a metal profile is stuffed onto the surface of the walls. The guides are placed with a step less than the width of the insulation by 2 cm. This will allow the material to be laid more tightly.
2. Mineral wool is placed between the bars and covered with a waterproofing sheet.
3. The film is attached to the crate with a stapler.
4. Thin slats are stuffed on top of the moisture protection, which will provide an air gap between the insulation and the cladding.
5. Siding is attached to the slats.

Slabs basalt wool strong enough to be mounted without a frame. Correct laying of the insulation begins with screwing on the bottom of a horizontal metal profile, which will keep the material from slipping. Plates are fixed with special glue and dowels with a wide head. Each row starts with an offset. After finishing all facade surfaces, a mesh is laid on the mineral wool and a layer of plaster is applied.

House insulation with polystyrene foam according to the "wet facade" principle

Panels of foam or extruded polystyrene foam are fixed to the wall using a simple technique called "wet façade" due to the presence of processes that require drying.

1. Preparation in progress brick wall: cleaning from dirt, elimination of defects, priming.
2. A metal profile is attached at the basement level, which will become a beacon when laying the first row and a drip for moisture.
   Glue is dotted on the insulation plates, and they are pressed against the wall.
3. Additional fastening with dowels is carried out - in the corners and in the center.
4. Work starts from the bottom of the corner, the rows are stacked with an offset for the stability of the structure.
5. On top of the finished insulation, a plastic mesh is laid for reinforcement and a thin base layer of plaster is applied.
6. After the mortar has dried, priming and finishing with decorative plaster are performed.

How to apply warm plaster to the walls?

Working with insulating plaster will take time, especially in the absence of painting skills. To properly prepare the solution, the mixture is diluted according to the instructions.

1. Brick walls are cleaned, protruding parts are removed. The surface is primed with a penetrating compound.
2. Plaster mesh and beacons are attached to create a common plane.
3. The prepared solution is applied to the walls. The thickness of the layer depends on the climatic conditions, but it should not exceed 5 cm.
4. Various decorative textures can be created on the finished surface.

The considered heaters can be used in any region, the thickness of effective thermal insulation is calculated according to local climatic characteristics.

Any homeowner, having built a house, certainly wants it to have comfortable living conditions, and one of these conditions is warmth.

If the heating system is installed correctly, of course, it will provide warmth to the house well, however, Russian winters are famous for severe cold weather, when heating system may not cope.

What is the best way to insulate a brick house from the outside? - this question is asked by every homeowner, because in the current conditions, when each kilowatt is expensive for the owner, this question is relevant and requires a rational solution.

By making the insulation even at the construction stage, you can avoid many of the problems that sooner or later the owners of private houses face.

It is more advisable to insulate a brick house from the outside than from the inside. If this is done according to all the rules, they will accumulate heat and prevent fungi and diseases from developing.

Even if the heating in the house is turned off, the walls will still give off the accumulated heat for a certain time. Therefore, this is the most effective method insulation to date.

Insulation materials

Minvata perfectly retains heat, allows air and steam to pass through, is fireproof and its prices are quite affordable. Ecowool is even cheaper, although it needs a special treatment with an antiseptic.

With its help, you can get rid of fungi in the voids of the walls. This material has only one drawback - too much ability to absorb moisture.

It insulates the house well and has a right to exist. However, it must be remembered that although the foam does not absorb moisture as well as mineral wool, its steam transmission capacity is also low.

In addition, it is very fragile, crumbles from small impact and releases toxic substances when burned. All these criteria must be borne in mind when choosing a method of insulation.

Extruded polystyrene foam

This material is similar to polystyrene, but with modern technology. It is a little more expensive and has some advantages:

• Waterproof;
• Durability;
• Resistant to deformation;
• Light weight and thickness;
• Low thermal conductivity.

"Warm" plaster

This is a newcomer in the construction market, but has already gained considerable popularity due to its very good characteristics.

It has many advantages:

• Good heat and sound insulation;
• Water vapor permeability;
• Does not absorb moisture;
• Non-flammable;
• Beautiful exterior decoration.

Other materials also have good thermal insulation properties and even better, but they do not retain them well under the influence of sunlight, frost or moisture.

In addition, they are not safe due to the release of toxic substances. "Warm" plaster does not allow bacteria to pass through and protects walls from mold, moisture and fungi.

So, treating the surface with this material, you can kill two birds with one stone - and insulate the facade and do preventive sanitization.

This material is also modern and gained popularity in a very short time. It combines two properties - heat insulation and wall cladding.

When choosing the best way to insulate a brick house from the outside, you need to remember that this material is much more expensive than the others, nevertheless it is worth it, since its advantages leave no doubt about the quality:

• A wide selection of textures and colors;
• Durability;
• Health safety;
• Aesthetics;
• Low weight;
• Easy installation;
• It is not exposed to diseases and fungi;
• Simple installation.

Polyurethane foam

It is a type of plastic and has a cellular foam structure. In the process of insulation, it is sprayed onto the walls, thus creating an excellent thermal insulation layer.

It practically does not allow steam and water to pass through, it is not afraid of corrosion, temperature extremes and adverse weather conditions.

In addition, it is highly durable and has low flammability. It is also an excellent sound insulator, resistant to microorganisms and is not afraid of mold.

Rodents and insects do not favor it with their attention and do not create nests in it. The service life of polyurethane foam is from 10 to 50 years, while its original properties are not lost or disappear over time.

The spraying process takes place quite quickly - in just a few hours you can completely cover the entire outer surface of the walls.

He also has disadvantages, which cannot be ignored:

• Its flammability is not high and it dies out quickly if it ignites. However, it emits strong smoke with toxic substances;
• Degrades over time when exposed to UV radiation;
• Relatively high price.

Summing up, we can say that each of the described materials is good in its own way and has both undeniable advantages and disadvantages.

And answering the question of what is better to insulate a brick, it is clearly not possible to give a definite answer. It all depends on what each owner prefers - quality or cheapness.

Video tips:

The construction market is wide and there are a lot of thermal insulation materials on it now.

Studying their advantages and disadvantages, comparing with each other, you will eventually come to some kind of compromise and choose a material that suits you and your home will be cozy and warm.

Undoubtedly, the main goal of every homeowner is to create optimal conditions for a comfortable stay. Warmth is one of the main indicators of home comfort, so today many are wondering how to insulate a brick house from the outside. The answer to this question is ambiguous, since several methods are most in demand, which will be discussed further.

Ventilated facades - an effective method of insulation

Making a choice in favor of a ventilated facade, a person solves two problems at once: firstly, money is saved on heating housing, and secondly, it is a good option facing. The construction of a ventilation facade is a difficult task, so it must be entrusted to specialists who know all the intricacies of the technology.

So, how does the insulation of a brick house take place in this way? The installation process consists of several stages:

So that the result does not disappoint, it is better to entrust the work on thermal insulation at home to professionals

• thorough cleansing outer wall from dirt, elimination of defects, sealing cracks;
• wooden blocks are stuffed on the wall in a horizontal direction at such a distance that the foam sheets fit tightly between them;
• foam is attached to the wall with construction glue;

This is important to know: the glue is applied to the entire area of \u200b\u200bthe insulation.

• after a while, when the glue dries, the foam sheets are fixed with special disc dowels;
• the seams between the sheets of insulation are sealed with glue;
• another layer of insulation is mounted on the wall of a brick house in order to improve the thermal insulation characteristics, but only now the crate is packed vertically. Due to this lathing, a ventilated gap is formed - it must be at least 40 mm;
• fastening a hydro-barrier, namely a dense synthetic film, which prevents the insulation from blowing out;
• from the effects of rain, snow, the thermal insulation layer is protected by siding, clapboard or facade panels, which are mounted on a metal fastening system.

Ventilated facades - a practical technology that protects walls from precipitation and mechanical stress

It is worth paying attention: not only polystyrene, but also glass wool slabs can be used as a heater.

Insulation of a brick house from the outside with the help of ventilated facades is a reasonable solution, because due to the appearance of the so-called "air curtain", heat loss is significantly reduced, and the temperature fluctuations of the walls are leveled. In addition, ventilated facades fully meet not only functional, but also aesthetic requirements.

"Light wet method" of insulation - which is better: mineral wool or foam

You don't need to convince anyone that the external insulation of a brick house is an important process, so you should choose the best one thermal insulation materialwith satisfactory performance. Common materials include rock wool and foam. And how are they different? Let's first consider the properties of mineral wool.

First of all, it should be noted that mineral wool is obtained as a result of melting slags of the metallurgical industry with the addition of basalt rocks. To perform insulation, they are used mineral wool boards, directly intended for facade finishing. Among the most valuable properties of this material are the following indicators:

• incombustibility;
• long service life;
• good sound insulation;
• low diffuse resistance.

In principle, during the production process, mineral wool undergoes hydrophobization, due to which water absorption is prevented. But, despite this fact, during storage and installation, it must be protected from moisture so that the material does not lose its insulating properties.

As for the foam, it consists of balls, the closed cells of which are filled with air. The advantages of expanded polystyrene related to insulation work are as follows:

• excellent thermal insulation properties - air does not move in closed cells;
• waterproofness;
• resistance to bacteria, fungus, mold;
• the material does not lose its properties at low temperatures, is widely used in areas with a high percentage of humidity;
• self-extinguishing - upon contact with fire, the foam melts, and after extinguishing the flame, it goes out;
• low vapor permeability.

Looking at the above characteristics, you can see that both materials have many positive properties, but foam is more often preferred. This tendency is explained by the fact that it costs an order of magnitude less, and during installation it does not get dusty like mineral wool. But here you need to understand that thermal insulation will serve for a long period if the material is made by a manufacturer with an impeccable reputation, which gives a guarantee for their products.

Wall insulation with foam - the nuances of the process

As already mentioned, the widespread use of foam as insulation is due to its excellent operational properties. We want to emphasize that insulating a brick house from the outside with foam is a process that requires strict adherence to technology.

First, consider what tool is needed to get the job done, namely:

• hammer drill - used as a powerful impact drill;
• a set of spatulas - foam plastic will be putty with these devices;
• knife - well sharpened;
• a hammer.

What materials do you need? We will answer this question too:

• foam sheets - the best option is polystyrene foam with a thickness of 80 mm and with a 25th density;
• assembly glue - as an option, cement glue for tiles is also suitable.

This is important to know: when calculating the amount of glue, you need to take into account that both foam sheets and a reinforced mesh will be smeared with it.

• fasteners - this refers to plastic fasteners with a wide head;
• reinforced mesh with 5 mm cells - it covers the entire surface of the foam glued to the wall;
• putty - it can be either a finishing putty or decorative plaster;
• deep penetration soil.

Styrofoam protects the walls from moisture and condensation, and in summer it keeps the room cool

And now we will talk about how to insulate a brick house with foam sheets. So, first, preparatory work, consisting of wall cleaning, leveling and deep penetration soil impregnation.

Please note: the external walls are primed to increase adhesion.

After this stage has been passed, you can proceed to the main work. First you need to dilute the glue and spread it on a sheet of styrofoam using a notched trowel. Further, the insulation is applied to the wall and pressed, but without excessive effort so that it does not burst. Then the foam sheet is fixed in at least five places with dowel-nails, called "fungi". If you need to cut the sheet to size, you should use a sharp knife and usually, but not a power tool.

After all the walls of the house are sheathed, it is necessary that they dry out (three days). If there are gaps between the sheets, they should be blown out with polyurethane foam. The next step is to reinforce the foam with a mesh. It is embedded in a thin layer of glue, which is applied to the surface of the insulation. It is important to remember two nuances here:

• the layer of glue should be as necessary as possible;
• pieces of mesh are glued with a slight overlap so that there are no cracks at the joints.

After all the applied materials have dried, the facades are finished. For example, it can be painting in the desired color or applying decorative plaster.

Decorative plaster "Bark beetle" has high strength and frost resistance

Is it possible to insulate housing from the inside

Of course, it is possible, but it should be remembered that in this case the dimensions of the premises are reduced. Insulation of a brick house from the inside is a process involving the installation of a metal or timber frame with the subsequent laying of heat-insulating material, vapor barrier film, wall drywall.

Insulation of walls from the inside is carried out in order to preserve heat and increase sound insulation properties

This is important to know: when insulating a house from the inside, it is necessary to remember the dew point, since non-observance of the technology will lead to freezing of the walls.

In addition, to achieve the best results, comprehensive insulation should be carried out, that is, not only walls, but also floors.

Answering the question of how to insulate a brick house from the inside and outside, it should be noted that all the above technologies require professional skill and relevant knowledge. Therefore, it is better to seek help from specialists who will do everything according to the rules. This means that the house will be warm and inexpensive to maintain in terms of paying heating bills!

If you are the owner of a private house, then among your tasks one can single out the creation of coziness and comfort inside the home. This is especially true for houses built of bricks. It can be quite difficult to choose a method of insulation, since thermal insulation materials are presented in a great variety on the market.

Ventilated facade

Insulation of a brick house outside modern methods is not cheap, but if the work is done independently, it will be possible to save money. As one of the methods of thermal insulation of walls, you can select Choosing this technology, you are solving two problems. Firstly, you will have the opportunity to reduce the cost of heating your home, and secondly, the facade will receive a modern aesthetic cladding. The main thing is to choose the right insulation. Stoves are the most used today, you can follow the lead of many consumers. The installation process will consist of several stages, initially it is necessary to clean the external walls of dirt, get rid of cracks and eliminate defects. Further, wooden bars are strengthened on the wall, which will be guides, the distance between them should be such that the free space fits the foam. The thermal insulation is fixed to the surface with construction adhesive. The composition must be applied to the entire area of \u200b\u200bthe insulation. After a certain time, when the glue has dried, the foam can be additionally reinforced with disc dowels. Do not try to choose the cheapest insulation possible. Plates for these works will be an excellent solution. The joints formed between the canvases should be filled with an adhesive. In order to improve the quality of thermal insulation, one more layer of insulation should be strengthened on the wall, while the grating should be located perpendicular to the previous layer of the frame. Due to this system, it will be possible to obtain a ventilated gap, the thickness of which should be 40 millimeters.

Nuances of wall insulation with a ventilated facade

If you are interested in the question of how to insulate a brick house from the outside using modern methods, then you should pay special attention to the described technology. At the next stage, the hydro-barrier is fixed, which can be played by a synthetic film. It is necessary in order to exclude the blowing out of the thermal insulation. The resulting layers must be protected by siding from the effects of precipitation; this finish is sometimes replaced by facade panels or clapboard. The canvases can be fastened to a metal system.

For reference

When equipping a ventilated façade, you can replace the foam with glass wool slabs. Whatever material is used, ventilated facades allow you to create an air thermal curtain, which reduces heat losses, and also neutralizes temperature fluctuations between the main wall and the decorative finish.

Use of mineral wool

When insulating brick walls externally, it is especially important to choose the right material. Among the popular heaters for carrying out such work, one can single out foam and mineral wool. The last version of thermal insulation is produced in the form of slabs, which are specially designed for facades. Among the positive characteristics, one can single out a long service life, insignificant diffusion resistance, as well as fire resistance and excellent sound insulation qualities. During manufacturing, it undergoes a hydrophobization stage, so that the material does not absorb water. Despite this feature, during storage and installation, the plates need protection from moisture, this is the only way to exclude the loss of the material's insulating properties.

Foam selection

Penoplex insulation is also quite common today, this material consists of many pores that are filled with air. Using this material, you provide the walls with excellent thermal insulation characteristics, which is guaranteed by air, which is the best heat insulator among the existing ones. The foam is watertight and resistant to mold, mildew and bacteria. It is not capable of losing its properties when exposed to low temperatures, therefore it can be widely used in areas where conditions are characterized by high level humidity. If insulation is made with penoplex, then you can count on the fact that when exposed to open fire, the material will show its qualities to self-extinguishing. The insulation will melt, and after removing the fire, it will go out. Considering the types of insulation, buyers quite often cannot decide what to choose: foam or mineral wool. Both materials are popular, but the first one is most often preferred. This trend is due to the fact that the boards are less expensive and do not generate dust during installation.

Preparation for insulation with foam

If you plan to insulate a brick house from the outside using modern methods, you can use polystyrene, however, to achieve positive result it is important to take into account the nuances of the process. The master must prepare a set of spatulas, a knife, a puncher, and a hammer. After visiting a store, it is best to purchase sheets that are 80 millimeters thick. The best option would be a density equivalent to 25. If you cannot find a special assembly adhesive, you can use a cement-based adhesive used in the tile installation process.

Glue consumption

If the walls of a brick house are insulated with foam, then it is important to correctly calculate the volume adhesive composition... The master must take into account the moment that the mixture will be applied not only to the thermal insulation, but also to the reinforced mesh.

Preparation of materials

The technology provides for the use of fasteners, which must be made of plastic and have a wide head. You will need which surface to cover. Be sure to stock up on putty, it can be finishing or decorative. For surface treatment, deep penetration soil is required.

Work technology

Having considered all types of insulation that are present on the modern market today, and having chosen polystyrene, you should familiarize yourself in more detail with the technology of thermal insulation. The facade must be cleaned, leveled and impregnated with soil. The last manipulation is necessary to improve adhesion. After that, you can begin to dilute the glue and apply it to the surface of the foam sheet, using a notched trowel. The slab is applied to the facade and pressed, but there is no need to be zealous, otherwise the canvas may burst.

When a brick house is insulated from the outside using modern methods, foam is often used, it will need to be strengthened mechanically after the glue has completely solidified. It is necessary to install the dowel-nails in 5 places of the canvas. To cut the sheet to size, you need to use a sharp knife, but you should refuse to use a power tool.

Surface reinforcement

The reinforced mesh is strengthened on a thin layer of adhesive, which is previously applied to the insulation. The mesh should be fixed with some overlap so that no cracks form at the joints. Once the mixture is dry, you can proceed to finishing facade. For this you can use paint or decorative plaster.

Preparation for facade insulation with siding

House insulation with siding is done after the installation of the crate. To do this, you need to prepare the length of which is equal to the height of the house. They are fixed vertically. These elements must be of the same thickness. Experts advise to treat lumber with impregnation, which will protect against rotting and fungus. If you decide to insulate a brick house with expanded polystyrene, then it can be used in tandem with siding. With ideal evenness of the walls, the crate can be omitted.

Insulation selection and tool preparation

Under the siding, you can install foam, extruded polystyrene foam or basalt insulation. Their cost may seem impressive, but with foam and polystyrene foam, you will need to use additional hydro and vapor barrier.

To carry out the work, you will need a screwdriver, a stapler, a tape measure, a building level, wood screws and staples for a stapler.

Siding installation

Before insulating a brick house, you must choose decorative trim, which will fit the exterior of the site. In the store, you have to choose basement or vinyl siding, the first option is more expensive, but it is reliable and durable. When attaching the slats, a building level should be used, which will ensure perfect evenness of the facade after completion of work. Near door and window openings, the dimensions of the siding may not coincide with the spans, in this case the vinyl trim is cut with a saw, but when cutting the basement panels, metal scissors should be used.

Warmth in a private house is one of the most important conditions for comfort and well-being in winter. In a cold, poorly heated room, it is quite difficult to imagine a comfortable stay - you will be provided with discomfort, poor health and health problems.

The main source of heat in a home is central heating, which does most of the heating work for the home. However, in addition to heating, wall insulation plays an important role in maintaining normal temperature, without which the heating system will not work as efficiently.

Insulation plays the role of thermal insulation, which will not allow cold to penetrate from the outside and at the same time retain heat inside. This is especially true in our climate, for which sudden changes in temperature are quite frequent. This is strongly felt in winter, when, under the prolonged exposure to subzero temperatures, the brick walls freeze through and the heating gives off most of its heat to nothing.

Even the initially correctly designed structure of a private house will suffer from the cold, if you do not resort to help additional insulation walls. Unfortunately, most of the buildings erected in the recent past do not provide for insulation. but modern technologies allow you to strengthen the thermal insulation of the house, regardless of whether it was included in the original project or not.

Surface preparation

Before insulating a brick wall from the outside, you should clean it of irregularities, bumps and residues concrete mortar... First of all, objects protruding beyond the common plane are removed - small pits and cracks do not matter much.

This procedure is especially important if you will use polystyrene or expanded polystyrene as insulation. Mineral wool will absorb small bumps and depressions due to its fibrous structure.

Note! Ideally, the surface to be insulated should be pre-plastered - then the base will become relatively flat and you will not have any difficulties with installation. However, the cost of the process in this case will increase - the price of the material spent and the hiring of specialists will affect.

After leveling, the surface should be cleaned of dust, crumbs, sand and other side elements. In the future, they can negatively affect the gluing process, making it less effective.

• The sheet to be glued should be firmly applied to the wall with all surfaces, and then pressed for a few seconds. Thus, all areas in need of insulation are pasted over;
• After two to three days, depending on the drying of the glue, the final fixation of the insulation to the wall is carried out by means of “mushroom” dowels, which are specially designed for this purpose. To do this, holes are drilled in the wall, taking the insulation with a perforating drill, into which fasteners are then installed. The holes are made in five places - at the corners and in the center;
• After the sheets are finally fixed, the wall should be checked for small gaps and cracks - such places should be treated with mounting foam with a small degree of expansion;

Installation of insulation under the outer covering

In this case, the insulation will serve as the basis for further finishing the facade - plaster, putty and other options of a similar class. In this regard, the process of its installation looks somewhat different than in the previous case. Here it is more advisable to use foam or expanded polystyrene, since they have a denser structure;

The procedure for insulation under the outer coating is as follows:

• The height and width of the walls are measured, the presence of door and window openings is noted. External ebbs are installed on the window sills - their removal is calculated based on the thickness of the insulation + the thickness of the layer of the future coating;

Note! If you plan to install gratings, it is advisable to do this in advance, otherwise in the future you will have to dismantle part of the space around the window opening.

• Then the sheets are adjusted to fit the wall - if possible, try to cut the insulation as little as possible to avoid unnecessary seams and voids. When cutting out the elements on the window sill - be guided by the fact that the sheets should overlap with the total area of \u200b\u200bthe wall - so it will be easier for you to join both planes in the future;

Note! If possible, consider the location of the sheets in such a way that the seam does not have a constant line, but is staggered. This will strengthen the surface and avoid cracks at the joint.

• After measuring and cutting the sheets, you can start gluing them. As in the previous case, the glue should be applied evenly, over the entire area of \u200b\u200bthe sheet, and then firmly attach it to the wall and press it briefly. A calibration spatula must also be used for this purpose;
• At the end of the drying time of the adhesive, the location of the holes for the clips is marked - four fasteners must be located at the corners of the sheet, and the rest at a distance of 30 to 50 cm from each other. Dowels, fixed with a perforating drill;

Note! In this case, the reliability of the fastening plays a very important role - it must withstand the weight of the finish. Accordingly, the reliability and durability of the entire future structure will depend on how reliably the base will be fixed.

Mesh gluing

• After the joints have dried, all irregularities should be sanded to a smooth state. We dilute the mixture for applying a protective layer, through which the reinforcing mesh is glued. Its density should be from 140 to 160g / m;
• Mesh fixation starts at the outer corner - first, a mixture is applied to the surface of the insulation, on which the net is then laid down, after which the remnants of the mixture are smoothed with a spatula. A properly fixed mesh must be completely in the protective mixture;
• After the mixture is completely dry, it is necessary to grout sandpaper to even out any unevenness. Then another layer is applied, the purpose of which is to level the surface after gluing. It should also be wiped, as in the previous case. After the leveling layer has dried, you can proceed with the primer and finishing;
