How is the insulation of a house made from foam blocks from the outside? Technology of warming a house from foam blocks How to properly insulate walls from foam blocks from the outside

A house made of foam concrete 30 cm thick will be insulated OUTSIDE + BLOCK HOUSE. Any questions!
D-600 blocks size 300x200x600 mm Wall thickness 300 mm
masonry on a sand-cement mixture with a fifth of lime to retain moisture in the solution.
Information on the properties of foam concrete walls is taken from STO-00044807-001-2006:
Laying of walls made of small aerated concrete blocks on a cement-sand mortar (γo = 1800 kt / m3 with a mortar joint thickness of 12 mm (λ and w are determined according to GOST 26254)
Blocks made of gas and foam concrete, gas and foam silicate, with a density of 600 kg / m3.
Thermal conductivity coefficient λB = 0.25 W / (m ° C).
Resistance to heat transfer of masonry from blocks: 1.2 m2 ° С / W.
The given resistance to heat transfer of your wall is now: 1.36 m2 ° C / W.
Heat loss through 1 m2 of the wall at your specified temperatures: 19.14 W * h.
As an example, I took from the same document as a heater:
Mineral wool products "Rockwool" and CJSC "Mineral wool" (Zheleznodorozhny)
Mats with a density of 35 kg / m3.
Thermal conductivity coefficient λB = 0.048 W / (m ° C).
When insulating 50 mm:
Reduced resistance to heat transfer: 2.4 m2 ° C / W.
Heat loss through 1 m2 of wall: 10.83 W * h.
With insulation of 100 mm:
Reduced resistance to heat transfer: 3.44 m2 ° C / W.
Heat loss through 1 m2 of wall: 7.55 W * h.
With insulation 150 mm:
Reduced resistance to heat transfer: 4.48 m2 ° C / W.
Heat loss through 1 m2 of wall: 5.8 W * h.
Calculations may have inaccuracies. In particular, the wooden lathing is not taken into account.
So:
1. As you can see, the dependence of heat loss on the thickness of the insulation is not straightforward. The thicker the insulation layer, the less the effect in reducing heat loss.
This relationship is true for all types of insulation. The numbers may change slightly.
You yourself will choose the required thickness of the insulation based on how much the cost of insulation is related to the savings in heating costs.
My opinion: 50 mm is not enough.
2. Foam concrete is a material with good vapor permeability.
As a heater, it is recommended to use materials with no less (or better, more) vapor permeability than foam concrete.
Mineral wool or cellulose (so-called Ecowool) or similar insulation. What exactly is up to you again.
PPP and especially EPS are materials with low vapor permeability.
Foam concrete itself is a good heat-shielding material.
Those. at the junction of foam concrete and insulation, the temperatures will be much lower than room temperatures and the likelihood of moisture condensation increases.
3. It is always better to keep warm on the outside. From the inside, there are many disadvantages and problems.
In your case, it is better to plaster from the inside. You can use "warm" plaster. Never drywall on the guides. Otherwise, temperature fluctuations between backfills " solid fuel"can be significant. The same applies to the ceiling with the floor. Not plaster, of course, but the material must be heat-consuming.
4. Walls are far from the only thing to look for to reduce heat loss.
P.S. I do not " experienced builder". And not a builder at all.

Foam blocks are called special building blocks white, consisting of gas silicate and foam concrete. This material is great for low-rise and high-rise buildings. The structure of the raw material has high adhesion to any finish, however, some owners of premises still decide on additional insulation. Fastening process different types thermal insulation is simple, you can do it yourself.

The relevance of insulation of houses from a foam block outside

Initially, foam concrete blocks were developed specifically for the construction of houses with single walls. Due to its good heat retention properties, a building lined with foam concrete does not require additional thermal insulation. Due to the fact that winters are harsh in the vastness of the country, builders recommend additionally insulating houses with the help of various materials.

House built from foam blocks

On the other hand, foam blocks are considered fragile raw materials, and if exposed to sub-zero temperatures for a long time, they can freeze and absorb moisture. For this, the walls are insulated from the outside, which gives the following advantages:

significant space savings, which cannot be said when insulating from the inside;
the integrity of the blocks is not violated, as if used internal insulation: the insulation layer additionally protects the blocks from freezing;
condensate does not accumulate inside, but is discharged outside, from where it is removed using air streams.

It is better to use lightweight options as a finishing material on top of the insulation. For example, cladding bricks will be too heavy, which is why most builders use paint.

Insulation types

Foam application

One of the most popular types of insulation for finishing and thermal insulation of a building facade is polystyrene or expanded polystyrene. The material has gained success due to its properties: it does not allow moisture to pass through at all. Polyfoam has good resistance to subzero temperatures, low cost can significantly reduce the cost of insulation.

Insulation of the house outside with foam

An important point is that on top of this type of insulation it is imperative to produce Finishing work... Polyfoam is not resistant to ultraviolet radiation, therefore, additional finishing is needed so that the raw materials do not undergo destruction.

The most popular types of polystyrene foam for insulating a house from foam blocks from the outside are the following brands:

Polyfoam Knauf Term. It has good vapor permeability, it is produced in sheets 1x1 meter. The thickness starts from 50 mm, it is used at temperatures from -140 to + 80 degrees. The cost of one sheet starts from 150 rubles, the cost for a pack of 10 pieces is 1450 rubles.
Carbon Eco. The size of one sheet is 1180x580x30 mm, the latter indicator indicates the thickness of the material. Operating temperature from -70 to +75 degrees. The cost for a pack of 13 pieces is from 1250 rubles.
Thermal insulation Ursa XPS. Polyfoam is suitable for insulation of foam block facades. Sheets are sold in sizes 1250x600x50 mm. For a pack of 8 pieces, you will have to pay from 1100 rubles.

Thermal insulation URSA

When insulating, you should pay attention to the side of the house: for example, on the south side, you can install insulation of a smaller thickness than on the north side.

Use of mineral wool

An inorganic material consisting of a large number of intertwined fibers is called mineral wool. This insulation is in demand no less than the above polystyrene foam. The material contains rocks and sedimentary rocks, as well as metallurgical slags. The main advantages of mineral wool when insulating foam concrete:

high thermal insulation properties;
heat resistance;
high sound insulation;
resistance to moisture absorption;
service life: 30-40 years.

Mineral wool insulation

The most common brand of mineral wool for insulation is the Technonikol company. It offers insulating material of basalt type Technolight Extra. The products are delivered in a pack of 8 plates each 1200x600x50 mm in size, while the range includes options with increased thickness. The cost of such a pack starts at 554 rubles.

Penoplex - analogue of polystyrene

This material looks like polystyrene, however, the technologies of their production differ. In the manufacture of foam, pressure and exposure to high temperatures are used. The output is very light, but durable material, which is also called extruded polystyrene foam. This raw material is resistant to compression, environmental friendliness, and impervious to moisture and mold.

On the market building materials for insulation of facades made of foam concrete, they offer the following options for foam:

Thermal insulation Penoplex Comfort. Plates are available in dimensions 1185x585x30 mm, while the thickness may vary. The material is produced in 4, 7, 10 and 13 plates per pack. For a pack of 13 plates, you will have to pay from 1400 rubles.
Penoplex Facade. It is produced specifically for thermal insulation of facades, it is produced in various thicknesses from 30 to 100 mm. The cost for one sheet is from 100 rubles according to the thickness.

Using foam for thermal insulation

The thickness of foam insulation must comply with modern standards, it ranges from 30 mm. Slabs of material are attached to a foam concrete wall with glue or on a dowel.

Features of insulation technology with various materials

When the thermal insulation material is selected, you can proceed to preparation. To do this, you need to make the appropriate calculations for the amount of insulation, as well as select tools. In almost every case, it is better to do the work together with a partner, since it is more convenient to fasten the dimensional sheets together.

Of the tools, special dowels with hats will be required; when laying the foam, it is also necessary to mount the profile guides made of metal. You will need a drill, screwdriver, hammer drill. When insulating with the "wet" method, specialized glue is useful. Materials for sealing joints are also required.

How to insulate a house from foam blocks outside with foam?

Before insulating the facade from foam blocks, it is recommended to make careful preparation. Walls should be free of excess sand, dirt and debris. If there are build-up mixtures on the surface, they are removed using a perforator. The process of foam insulation looks like this step by step:

Application of a primer - it will provide increased adhesion of the adhesive to the surface of the foam concrete.
Installation of a basement profile at the bottom of the wall - it will serve as a support for the insulation.
Glue preparation - carried out using a special drill attachment like a mixer.
Foam preparation - the material must be roughened with a needle roller.
Applying glue to the foam with a spatula.
Fastening of foam plates to foam concrete: carried out from the bottom up, umbrella dowels are attached at the corners and edges.

Foam insulation outside

When the process of installing the insulation is completed, you need to wait a little time for the material to shrink, and then start finishing work.

Thermal insulation of foam concrete with mineral wool: stages of work

When choosing mineral wool as insulation, you must have certain skills in working with it in order to carry out the process in accordance with all the rules. It is better to carry out the procedure together with a partner, according to the following instructions:

clean the walls, achieving a flat surface;
process the area for insulation with an antiseptic;
install fasteners for the lathing;
attach thermal insulation pads;
place a guide base at the bottom of the wall;
insert the insulation, fixing it on the dowels: they must be screwed into the wall to a depth of 40 mm;
lay the windproof membrane on top of the mineral wool.

The use of mineral wool for thermal insulation outside

For finishing the facade of a house insulated with mineral wool, it is recommended to use plaster and further painting.

Warming with penoplex: rules

To use penoplex for thermal insulation of a foam concrete house outside, it is recommended to follow a number of rules that will help to keep the heat inside the room as much as possible without loss. Step-by-step instruction looks like that:

Leveling the facade surface, sealing cracks.
Processing with a soil mixture.
Making glue.
Gluing foam boards and their subsequent fastening to dowels.
Installation of reinforced mesh for finishing.

In this case, the work can be performed by one person, since the foam sheets are lightweight and quickly lend themselves to installation. It is not worth using additional materials for vapor barrier, because penoplex already has good vapor permeability properties.

What material is most preferable: possible harm to health

If you are puzzled by the issue of operational safety, then all of the above materials will not harm a person when competent installation... Each of the presented types of raw materials is made with the use of anti-flammable additives, which prevents ignition in a fire and leads to self-extinguishing.

Comparison of different materials for heat preservation

Despite the fact that formaldehyde binders are used in the production of mineral wool, it will not release harmful substances due to the location outside the building.

Answering the question whether it is necessary to insulate a house built from foam blocks, it should be noted that additional thermal insulation never hurts. The use of foam, mineral wool or foam will only enhance the thermal insulation properties of foam concrete and will maximize the preservation of heat inside the room.

Foreword... Consider in the article how to independently insulate a foam block house from the outside under siding and under plaster. For many owners of foam block houses, the thermal insulation of the room comes to the fore. We will tell you about the technology of using mineral wool, polystyrene or penoplex when insulating a facade from a foam block, at the end of the article, see the video instruction on insulating a facade from a foam block of a house with mineral wool.

Under the term "foam block" private developers mean blocks of foam concrete or gas silicate. This material is used today for the construction of low-rise buildings. The foam block itself is an insulating layer. Earlier we told how to insulate a house from gas silicate with our own hands. Today we will analyze the issue of self-insulation of the facade from the foam block from the outside.

Due to their porous structure, foam concrete blocks provide excellent adhesion to any finishing material(plaster, putty). Many owners country houses from foam concrete blocks they often resort to its insulation. Is it worth insulating a foam block outside and how to properly insulate a house from a foam block for the winter? What materials are best used when carrying out work, read this article.

Do I need to insulate the house from the foam block from the outside

Many will ask, is it advisable to insulate a house from a foam block? Since, foam concrete was invented for the construction of buildings without additional thermal insulation, since they have a minimum low heat transfer coefficient. At the same time, the problem of condensation formation between the insulation and the foam block wall disappears by itself. However, during the Russian winters, a lot of money will be spent on heating the house.

Insulation of the foam block with foam plastic with cladding

For the high heat-saving qualities of the foam block, you have to pay with the low strength of the walls. Walls made of this material are quite fragile and will not be able to withstand the heavy load of "wet" or "ventilated" facades. In addition, the foam block is afraid of moisture and freezing; foam, extruded polystyrene foam and mineral wool are often used to insulate a foam block house outside.

Experts advise against carrying out independent insulation foam block houses from the inside, from the side of the heated room. However, if it is simply impossible to decorate the walls from the street, and in winter it takes a lot of money to heat the room, then it is simply necessary to insulate the house. The thermal insulation layer can keep the room warm and pleasant.

How to insulate a house from a foam block outside

What is the best material to choose for thermal insulation of the foam block from the outside? The ideal option for this is plate material: Isover mineral wool mats, foam or extruded polystyrene foam. When using mineral wool, it is necessary to protect the material with waterproofing and it is imperative to equip a ventilated gap that will remove excess moisture and possible condensation from the film surface.

Mineral wool is an environmentally friendly, vapor-permeable material that can shrink if installed incorrectly. Expanded polystyrene and polystyrene is a moisture-proof and vapor-proof material with a low heat transfer coefficient. When laying foam or polystyrene plates on the facade, the thermal insulation material should be protected with a decorative layer from mechanical damage and ultraviolet radiation.

External insulation of a house made of foam blocks is an important component of the entire structure. After all, this is the thermal insulation of the room and, accordingly, the price for heating. Today we will look at how to properly insulate a house from foam blocks from the outside.

There are tons of materials on the retail market today; if the work is done incorrectly, the money spent will not give the desired result. In the video in this article, you can watch how this work is done and choose the material you need.

House insulation from foam blocks

Insulation of houses from foam blocks begins with the right choice the desired material. After that, calculations and purchases are made. Let's figure out in order how to insulate a house from foam blocks from the outside and how to do it correctly.

Material

So, the better to insulate a house from foam blocks from the outside, it is not difficult to answer this question. The material must withstand temperature extremes and high humidity.

Attention: It is necessary to combine insulation and its thickness for each wall separately. For example, a wall with south side gets more heat. This means that the layer can be made smaller than on the others. To protect the house from various rodents, the lower belt of the facade is insulated with extruded polystyrene foam. The corners of the building are insulated with a thicker layer of material.

Insulation outside the house from foam blocks is most often done with the following materials:

Mineral wool

It is an inorganic material that consists of a large number of fibers intertwined with each other.
It is produced by melting rock or sedimentary rock, as well as metallurgical slags.
For insulation, several types of mineral wool are used: glass (glass fibers) and stone (rock).
Wool slabs are used for various insulation methods. "Wet" - consists of 3 layers. These are thermal insulation, reinforcing layer and "fur coat". "Hinged ventilated facade" - cladding, ventilation layer, insulation, frame.
Advantages: heat resistance, high thermal insulation, resistance to damage, resistance to moisture absorption, excellent sound insulation (noise reduction up to 20%). The period of use reaches 30-40 years.

Styrofoam

This is the most common material used to insulate the walls of buildings.

Production began in the 1930s. To this day, it occupies a leading place among all heaters. Very good thermal insulation. It is due to the manufacturing technology, which consists of foaming polystyrene with special equipment. As a result, small air bubbles appear.
Light weight and resistant to moisture penetration. It is ensured that the foam contains 98% of air from its total mass.
Another advantage is the low manufacturing cost and low cost of insulation work. With foam finishing, heat loss is reduced by almost 70%.
Thanks to modern technologies, it has great fire resistance (does not burn and resists fire well). However, the foam is very easily "surrendered" to small rodents. If they are present on the territory or in the premises, then the use of this type of material will have to be abandoned.

Attention: How to insulate a house from foam blocks, here you need to look at the structure itself. After all, foam attracts rodents and they live well in it. Therefore, for residential premises, this will not be the best option.

Preparing the walls

Now we will consider how to insulate a house from foam blocks from the outside, and here it will already be necessary to perform the right technology installation. Everything can be done by hand, and therefore the price will be limited to the cost of materials.

High-quality and long-term operation of the insulation is due to the correct preparation of the base and base for subsequent work.

So:

First of all, all the elements that protrude beyond the plane of the walls are dismantled. These are ventilation grilles, gutters, outer segments of fans and air conditioners, lighting... If communications and engineering networks get to the surface where work will be carried out, then they must be removed. Also, decorative parts of windows and cornices are subject to dismantling. This is very important for old houses.
Walls under the plaster must be tapped for stability. Deviations from verticality and unevenness can be detected using aluminum rules, plumb lines and cords. If there are problems, they are marked with chalk so as not to miss.
When there is a large gap in the level of the planes on the building or there are broken and thin parts of the wall, then they urgently need to be corrected or removed. Only after that, start work on the insulation of the facade.
Parts with oil paint are carefully handled as they impart poor adhesion to the surface and reduce the vapor transmission ability. Fungus, rust and mold are removed from the walls. Cracks are primed with wide brushes with special compounds with a high degree of permeability, and putty until completely dry. Potholes up to 2 millimeters do not need to be repaired, and large ones are leveled with pieces of insulation.
After completing all activities preparatory work stop. Now they start the very insulation with expanded polystyrene.

Fastening the plinth profile

Insulation of a house from a foam block is done at the same level. We must not violate the geometry. Before starting work, you need to find a starting line.

So:

For this, according to the project, there is an extreme point below the surface for insulation. Then the mark is moved to all corners of the building with a hydraulic level (the principle is based on the theory of communicating vessels). Remarks are connected to each other. Line found.
The base profile is fixed with dowels strictly according to the marking. It is necessary to give emphasis and prevent movement of the extreme row of insulation (wet glue has great mobility).
Depending on the width of the insulation, the starting bar is selected. It is secured with hammer nails with washers with an interval of about 300-350 millimeters.
The starter bar can be connected in various ways. The method of joining the edges with diagonal cuts or using a corner connector (for an overlapping joint) is used. To compensate for expansion under the influence of temperature, plastic elements are installed between the profiles.

Installation of outdoor window sills

A house made of foam blocks must be insulated from the outside, taking into account all openings. It is recommended to install these sections before fixing the insulation to the facade.

Water protection strips are installed to the window:

The window sill is carried out beyond the wall level by no more than 30-40 millimeters. In this case, it is necessary to take into account the thickness of the insulation on the wall. When the installation takes place on the starting profile, a cavity is formed under the windowsill, in which water will accumulate. Pieces of insulation will help get rid of this. They are mixed with glue and plastered.
After mounting the windows, there are small places for their subsequent insulation (about 20-30 millimeters). It uses foam that is less wide than the standard material used. To leave room for other layers, subtract 1 centimeter from the thickness. To insulate the outer slopes, the foam does not need to be cut. It can protrude 1 centimeter beyond the level.

Adhesive solution

The glue is able to quickly harden and harden. To do this, when gluing insulation, you need to prepare the exact amount of solution required for a given period of time.

A bucket is taken and the dry mixture is poured into it... Filled with water in the right proportion. The whole mixture is mixed with a drill at low speeds until a homogeneous mass is formed (there are no lumps). A delay is required (about 5 minutes), and mixing is repeated for another minute.
When the glue mass begins to harden, it must be mixed again.... It is strongly not recommended to use plain water to dilute the density. Depending on the thickness, you can combine the methods of applying the solution. This compensates for the differences in planes.
On the sides of the insulation plate, a strip of glue is smeared (height about 2 centimeters). Beacons are evenly placed in the middle. This will help if the irregularities are large (more than 15 millimeters). Less - stripes are applied both along the perimeter and in the middle. They are 3-4 centimeters wide. The glue should cover half of the sheet or slightly more (50-60%).

Insulation sticker

The slopes are already insulated, the window sills are in their places - the pasting of the walls begins. The facade is insulated using a certain technology. Fixing first with glue, and then with dowels.

Attention: It should be said right away that when fastening, the insulation should not be deformed, otherwise it will lose its properties.

The process begins from the bottom, where the installed bar is located. 2 spatulas are used. The first is designed to apply glue to the second. The small one measures about 8 centimeters, and the large one is at least 20.
The adhesive mixture should be applied only to the wall, not to the area of the sheet. The uneven configuration of the wall allows you to impose more mass. This is necessary when unevenness exists. Once leveled, the grout spreads in a straight line and unevenly. The sheets are fastened in a T-shape.
When laying the sheets in their place, you need to leave a small gap (2-3 cm). Then it is squeezed with a rule or with a long squeegee to the level of neighboring plates. Excess glue protrudes along the base and inside. They should be removed. The level checks the verticality of the plates, and the flatness is checked with control threads.
The foam is pressed one to one at a short distance (about 2 millimeters). The adhesive solution must never get into the joints between the boards. If this nevertheless happened, then the distance is filled with separate small pieces or foamed. The threshold between the joints must be no more than 3 millimeters.
A prerequisite is that the joints and slopes near doors and windows do not fall into one perpendicular line. The combination must be either above or below. The distance is not less than 20 centimeters. If a situation arises when the boards are glued on different materials(brick turns into wood), then it is necessary to leave a minimum gap of 10 centimeters without joining.
The corners of the facades have a different connection method (notched). This applies to both outdoor and indoor. To prevent the formation of cracks, it is necessary that the placement of the boards does not result in a long vertical seam. This can be avoided by wedging the outer rows into the area of adjacent walls. It is imperative to keep the release for layering on slopes and corners. When the glue is frozen and the angle is determined, you can slightly trim or sand the foam. It is trimmed with a large knife or saw using a square or metal ruler. This will allow you to cut straight and neatly. Do not touch the already glued board. There will be a violation of the connection of the material to the wall. If it is necessary to correct, then the mixture is reapplied and glued in a new way.
Now you need to wait a certain period of time. At least 3 days. This will allow the glue to adhere well, and the material will return to its normal position. If the insulation is done independently without professionals, as well as other assistance, it is recommended to do this. separate sections... One part is made from below from the ground, the second from above using scaffolding (scaffolding). In order not to drag them back and forth, you need to glue the material first from the lower level.
When the whole house is insulated in one go, the foam sheets will be outdoors for at least a couple of weeks. The sun will dry it out, and the rain will add moisture. From such influences, the quality of the material will significantly decrease. The areas to be treated should be at least as wide as the scaffold and the height as the worker's height.

Nailing insulation

Nailing plates in fresh mortar is also not advised. This provokes the ingress of the adhesive mass under the sheet, which will inevitably lead to delamination of the edges.

So:

For fastening the insulation, special dowels are used. They are called fungi. This is a plastic sleeve with a cap on top. large diameter... A metal or plastic nail is driven into it. It is not recommended to choose the metal, because it is more expensive (leads to an increase in the cost of repairs) and has good cold air conductivity.
Density of distribution of nails per 1 square meter is 6-8 pieces. They are attached to the center and corners of the insulation sheet. If the size of the house is large and large slabs are used, then additional sheet fasteners are required. This will match the reliability and stability as well as wind loads. Dowels are driven in at the corners of the building and near the slopes at a distance of 20 centimeters from the border of the slab.
Holes of the required diameter and depth are drilled with a hammer drill. Before attaching the dowels, all dust is removed. The length should be slightly longer (1-1.5 cm) than the rod. This will allow loose debris not to interfere with the installation of the dowel. The length of the fungus is calculated as follows: the thickness of the insulation sheet is taken, 10 millimeters are added to other layers and added to the amount of penetration into the wall (about 40 millimeters).
The dowel is inserted into the resulting hole and fixed. Take a rubber mallet, and if you don't have one, you can use your own fists.
Fixing the dowel should be flush with the insulation or slightly higher than it (no more than 1 millimeter).

Attention: There are times when the hat protrudes and does not go further. This means that the taper is deformed or the hole is not drilled deep enough. It was clogged with debris. The plastic fungus is pulled out, the dirt is cleaned out and the hole is made deeper. The dowel is inserted back and locked in place.

Reinforced layer

It is used to protect insulation. For this, an adhesive solution and a fiberglass mesh are used.

For gluing corners, openings, separate pieces of reinforcing mesh are used. Dimensions: 200 × 300 mm. You can take more. This will eliminate the occurrence of cracks from temperature extremes, mechanical stress inside the corners.
So that all the corners of the building, decorative ledges and slopes are not knocked off and are strong, they are reinforced with perforated corners. They are made of plastic or aluminum and are supplied with a mesh. A solution is applied, the corner is firmly pressed and leveled in all planes. Before installation, the perforated corner is adjusted to the required size.
If excess glue comes out, then it must be pulled onto the wall. The corner has holes, thanks to which, with the help of nails, you can level and tighten it on the plate. Wait a while for the initial layer to completely solidify. After that, a reinforcing mesh is installed.
To strengthen the insulation, a special mesh is used, which is designed for such work. It contains fiberglass impregnated with alkaline substances. Thanks to this, it can withstand the required loads. To protect the mesh from impact, a special solution is used. It differs from the glue mixture, which is used to attach the insulation to the facade.
Before proceeding with the installation of the mesh, the plates must be prepared. They are sanded by hand with trowels or coarse sandpaper. This will remove any irregularities that may have formed at the joints. After processing, all the resulting debris (dust, dirt, abrasive particles) must be removed. The height of the walls is measured and according to this size the mesh is cut into strips. The glue is applied in strips equal to the width of the resulting mesh pieces.
Application of mortar is best done with a metal float. The layer should be even and not thick. Approx. 2 mm. After application, the mesh is unwound to its full length and applied to the plane. Press it in with a smooth spatula. After that, the edges are aligned. Movements start from the center. Excess glue is smoothed over the surface.
Until the solution has hardened, an additional layer is applied. After aligning it, the mesh should not be visible. Now it's worth waiting for everything to dry and harden. Everything is finally sanded with sandpaper, and small grooves are putty. After 3 days, the walls are dry and ready for quartz priming. This will facilitate the subsequent decorative plastering process.

Insulating a house from foam blocks outside is a rather important question. You shouldn't rush here, but everything should be done carefully and thoroughly. Look at the photo and make a plan for the work, the instructions will not allow you to miss the details.

Warming is a very important step in preparing for winter. Therefore, it is important to understand how to properly insulate a house, and what you need to know in order to keep warm in your room.

As practice shows, up to about 30% of the heat is lost as a result of poor insulation of the walls.

This can lead to improper design, the use of old building materials, as well as a complete disregard for basic standards.

Insulation can be carried out both inside the house and outside. Walls, ceiling, floor, windows can be insulated. But experts say that the most effective is external insulation of the walls of the house.

Home insulation technology is very similar, and in this article we will consider the outdoor insulation method as a more effective method.

As a heater, both outside and inside, such materials are suitable as:

The most effective view insulation is considered external wall insulation. This type of insulation has its undeniable advantages.: reliably protects the entire structure from adverse environmental conditions (rain, wind, snowfall, and so on), contributes to an increase in the level of noise insulation, blocks the manifestation of fungus and mold (from inside the house).

Differences in insulation

The main property of this type of insulation is to minimize heat loss during the cold season, as well as reduce heating on hot summer days. Plus, keeping your walls warm can save you a lot on your heating bill.

You can perform this operation various materials , which differ in the type of the feedstock itself:

organic;
inorganic;
mixed.

There are many varieties of materials on the building market. which will help to make the walls warm, and as a result, increase the energy efficiency of the whole house:

mineral wool- a special fibrous material that can be obtained by melting rocks, various kinds of metallurgical slags and their mixtures. A fairly common material for wall insulation, it is found in the form of a roll or slabs. There are several options for such cotton wool, which differ in their density;
glass wool... It is a fibrous material (mineral fiber, similar in its properties to mineral wool). It can also be found in rolls or slabs. There are several material options that differ in density, thermal conductivity;
polystyrene, aka expanded polystyrene... Gas-filled plastic that has many air bubbles. It can only be found in slabs. It differs in density and flammability.

Types of insulation

All these materials are necessary in order to insulate the house from the outside.

How to fix the material

The following types of fastening of insulation materials can be distinguished:

fastening the selected material using various kinds of adhesive mixtures... After their application, plastering is carried out;
a method of installing the material in which a small gap is specially made... The wall is mounted in just one brick. For this, a special solution is used. This installation method is called - three-layer non-ventilated wall;
ventilated facade... First, the wall is protected with special waterproofing, on top of which the insulation itself is already attached, and then the windscreen is mounted and, of course, the outer sheathing is installed on the frame itself. It can be clapboard or siding.

It is worth noting that each of the technologies has its own advantages and its own nuances of implementation.

External insulation methods

Before starting an operation to insulate a house, you should understand that the choice of material depends on the specific conditions of its use. Having studied the possible insulation materials, the following pros and cons of each of them can be noted:

wadded heaters... All of their varieties have good sound insulation properties, in contrast to foam (using foam, it is worth in addition to use contractions for sound insulation);
cotton-type materials are afraid of moisture, and this is quite logical... Only 2% of getting wet is enough, and the properties of such a heater drop by all 50%. Be sure to store the material in places where there is no moisture;
foam is a combustible material, and it is best to choose the one that belongs to the G1 group.

Before starting the insulation process, you should understand how the wall cake works, and what you need to know in order to insulate the walls correctly and competently.

A foam block house is a fairly popular design, which has its own advantages. At the heart of such a structure is a very rigid structure of certain vertical posts with horizontal bridges. Small cells are formed, in which the insulation itself is laid (the one that was determined in advance).

Wall cake

Despite the fact that a wall cake of this design is quite simple, it has its own nuances and must be performed in accordance with all the rules.

Such a wall consists of:

outer layer, it is also facing;
membrane of special design;
the place where the insulation is installed is the crate. Mineral wool is most often used as a heater;
sheets of vapor barrier material;
the last layer is lining from the inside.

Wall cake

Despite the fact that a house made of foam blocks is being built so that its walls bear minimal heat loss, it should also be insulated.

Vapor barrier and waterproofing

So that the wall insulation is not in vain, it is worth remembering all the necessary steps, one of which is - installation of vapor barrier... Such an operation is necessary in order to provide the structure with moisture protection. It is especially relevant in damp rooms.

A procedure such as vapor barrier is a kind of barrier between water vapor and insulation.

When working with such material, you must be extremely careful, do not pull the coating too much so that the film does not break.

Depending on the type of walls, the vapor barrier procedure can be different:

if the walls are processed inside the house... It is worth remembering that the film is applied horizontally, from bottom to top. The fastening process itself is carried out using a stapler or small nails. The film overlaps, the joint of which must be at least 15 cm. After that, the vapor barrier layer is fixed with a wooden frame. It should be understood that the quality of the procedure performed also depends on the quality of the film. It is worth buying high quality and modern materials;
vapor barrier for siding... If you are planning to cover the house with siding, you should not neglect the vapor barrier. It is best to use foil film. The insulation itself is made with the reflective side outward. The procedure is the same as for internal work;
for... A feature of this type of house is the absence of a rigid base, and as a result, the vapor barrier procedure is carried out between the racks. This type of house cannot be rented out without vapor barrier.

Vapor barrier and waterproofing

NOTE!

Along with vapor barrier, there is another way to protect the structure from moisture - waterproofing... To get 100% positive effect, apply these two methods at the same time.

During this procedure, the following materials are used:

ruberiod... Special cardboard, which, in turn, is impregnated with petroleum bitumen, while on both sides it is coated with refractory resin;
roofing paper- cardboard, which is treated with tar composition;
glassine which is impregnated with bitumen;
waterproofing membranes - the most the best option .

The wall, which will give your home warmth, protect it from moisture, should consist of the following layers: wall, vapor barrier layer, insulation (most often mineral wool), waterproofing film.

Insulation of the facade from foam blocks from the outside for siding

The walls of the house can be uneven, and there is nothing to worry about. But the process of warming itself should be carried out on flat surfaces what to do in such a situation? For this, use a metal, or wooden crate ... It is she who will help hide all kinds of flaws on the facade of the building.

The rules for establishing such material are simple:

before you start installing the crate on the facade, you should clean it of dust, dirt (you can use sandblasting);
in no case carry out the process of installing such a crate at temperatures below -10 degrees;
it is imperative to leave a place for insulation (for example, for mineral wool);
when installing the lathing no need to screw in self-tapping screws to the very end(all the way);
the crate has its own step and it must be chosen based on the dimensions of the facade panels themselves.

Lathing for siding

After carrying out such a procedure, you can begin to insulate the facade. Step-by-step instructions on how to insulate the facade of foam blocks using mineral wool:

the first thing to do is to free the entire facade of the house from dirt and dust. Also take pictures of different brackets, communications, and so on. Make the walls "bare";
be sure to seal all cracks, cracks with a special solution;
let it dry, then apply antifungal agents (you can buy them at hardware store). You do not need to apply to all walls, do it only where there is a wall will be exposed to moisture. This is necessary so that there is no mold and mildew;
install the crate, best of all from metal frames;
lay a vapor barrier;
start laying rock wool slabs. Craftsmen advise using cotton wool in slabs, since working with rolls is not convenient and will bring a lot of problems.
after the insulation material has been laid out, it is worth applying waterproofing;
carry out the siding process (vinyl / metal);
on the building materials market, you can find mineral wool different sizes, but the best option is a 10 cm thick slab.

Output

It is quite possible to carry out the insulation of a foam concrete house on your own. It is important to properly process the walls, before sheathing with insulation. Depending on what kind of house you have, what material it is built from, the insulation procedure may differ slightly.

Whatever material you choose for wall insulation, you need to do everything strictly according to the rules, and then your house will be warm. If you do not know which material is better to choose, mineral wool, or foam, consult with the masters. But as practice shows, mineral wool / glass wool is most often used, since it has many advantages.
