How to sheathe a cinder block house. Insulation of cinder block walls. Insulation using a spray solution

Today we will tell you how to insulate a cinder block bathhouse from the inside and why, contrary to the instructions of heating engineers, you have to do exactly interior work. Houses should be insulated from the street side using one of two methods. The cinder block is laid in one row, unlike brickwork there is no air buffer zone, and as is known, air - best heat insulator. The blocks are afraid of moisture and they are very cold, so you can’t do without insulation in tandem with special films.

Choosing material for cinder block walls

Without insulation, a cinder block house will be cold.

Before we talk about the method of insulating cinder block walls from the outside and inside, let’s decide on the materials:

mineral wool (mats or );
liquid thermal insulation (PPU, penoizol, );
expanded polystyrene (regular and extruded);
penofol.

Besides thermal insulation materials, special films are used. Before insulating a cinder block house, let’s look at the types of films (membranes) that are used to protect thermal insulation. There are three types in total:

wind barrier - does not blow through, allows moisture and steam to pass through;
waterproofing – protection from moisture, allows steam to escape from the thermal insulation;
vapor barrier - does not let anything through.

It is important to lay membranes right side, otherwise they will not perform their tasks. In principle, the choice of thermal insulation largely depends on the conditions under which the thermal insulation will be used. For example, in a house or a bathhouse, because in the latter not only increased level humidity, and very high temperatures, especially in the steam room. It is very important that the thermal insulation withstands high temperatures and does not emit toxic substances.

Internal or external insulation

How to properly insulate a cinder block house: from the inside or the outside? We have discussed this issue more than once and once again we will repeat that, according to technology, thermal insulation should be attached from the street side. Only in this case you do not risk moving the dew point to inner part walls will get worse results than before insulation. There are situations when you have to install thermal insulation inside, for example, in a steam room, because by insulating a cinder block bathhouse from the inside, you will protect the walls from moisture, which is also very important. Concrete blocks in conditions high humidity will last much less.

In addition, insulating a cinder block house from the outside is necessarily accompanied by a calculation of the thickness of the insulation. In each case, this indicator will be different, the result is affected by:

region of your residence;
wall thickness.

During the construction of walls, the blocks are placed on edge or laid flat, and in one row. It turns out that there is no air buffer zone, as with brickwork. Practice has shown that even if you choose the largest blocks, such buildings cannot do without additional thermal insulation.

How to insulate cinder block walls from the inside

The steam room in the bathhouse is insulated from the inside.

Internal insulation cinder block houses are not welcome, unless, for example, you can use special paint with ceramic hollow spheres or penofol as additional thermal insulation. As independent materials they are ineffective. Thermal insulation of cinder block walls from the inside is practiced in steam saunas, when it is additionally necessary to protect the walls from moisture. In this case, the main thing is to prevent moisture from the steam room from getting into the insulation layer. Naturally, you can only use mineral wool. Work method:

on inside walls are being erected in the steam room wooden frame;
Mineral wool, preferably basalt, is placed between the guides;
foil insulation is spread over the sheathing - it is very effective for saunas, as it blocks infrared radiation and does not allow steam to pass through;
a second tier of sheathing is installed on top of the foam foam;
A wooden lining is attached to the second tier.

Mineral wool needs to be laid in two layers and ensure that the joints do not coincide. The minimum insulation layer is 10 cm. The main thing is not to forget to glue the foam foam joints with special (not stationery) tape. Also, one should not neglect the ventilation gap between penofol and wooden clapboard. Without it, reflective insulation simply will not work, and besides, the condensation on the foam foam must evaporate. Penofol foil often has small holes that are invisible to the eye. Therefore, to be on the safe side, you need to lay a vapor barrier membrane under the penofol.

External insulation method

Methodology wet facade.

External insulation of a cinder block wall is performed using two methods:

wet facade;
ventilated facade.

Before you insulate a cinder block house from the outside, you should decide on a methodology to make it easier for you to figure out what will be more profitable. A wet facade is the application of plaster directly on top of the insulation. This method is possible using mineral wool or foam plastic (regular and extruded). The density of wool must be at least 50 kg/m. cube, foam plastic not less than 25 kg/m. cube, a larger error is welcome.

How to insulate a cinder block house from the outside using the wet facade method:

the wall must be smooth and primed;
The thermal insulation is glued to the wall and fixed with dowels;
a layer of putty is applied, a reinforcing mesh is embedded in it, a special one is used at the corners plastic corner;
a second layer of putty is applied on top;
the surface is primed and painted.

Mineral wool is glued to universal dry construction adhesive, which must be diluted with water, and can also be used to putty. Polystyrene foam, in addition to such glue, can be attached to adhesive foam - similar to mounting foam, but intended for polystyrene foam boards.

If the insulation is laid in two layers, then the slabs of each layer must be secured with dowels, because they will be subject to the load not only from the weight of the thermal insulation, but also from two layers of putty. Naturally, all seams are foamed and they should not match. Do not ignore slopes; cold air enters the room through them.

Ventilated façade technique.

The ventilated façade technique consists of constructing a structure with outside, where the thermal insulation layer will be blown. This is necessary to remove all possible condensation and for cooling, which is convenient in the hot summer. The technique can be used:

mineral wool;
polystyrene foam with its derivatives;
liquid thermal insulation;
ecowool.

First, the first level of sheathing is erected, then the thermal insulation stage. Mineral wool and foam plastic are glued, and ecowool, polyurethane foam and penoizol are sprayed onto the wall using a compressor. Afterwards, any film is laid, which should first of all be a wind barrier, and if it still does not allow moisture to pass through, this is only a plus. The next level of sheathing is built on top of the film, which is necessary so that there is a ventilation gap between the thermal insulation and the finishing. In the buffer air zone, flows always circulate from bottom to top, like an exhaust hood. Considering this fact, Special attention it is necessary to pay attention to the degree of flammability of the materials used. Should choose , which we already wrote about once.

Brief summary

Before you insulate a cinder block house from the inside, remember the parting words of heating engineers: “ Good result provides only external insulation.” Work inside is carried out only if it is necessary to protect the walls from the destructive effects of moisture, for example, in a steam room. In houses, internal thermal insulation can be an addition to the external one, nothing more. From the street side, a house can be insulated using two methods: wet and ventilated facade. Before work, always consider which layer of thermal insulation is needed specifically in your case.

Before you insulate cinder block house from within on your own, you need to know the rules for carrying out such work. It is important to choose materials that are suitable for this.

Today construction market filled with such products. There are a large number of them. They are usually made from mineral wool or foam. Insulating a building with one product or another requires certain skills. How to properly insulate a cinder block house will be discussed below.

The slag-filled house itself is warm, especially if the thickness of the slag-cast wall in it is more than 30 centimeters. But in order to spend less on heating in winter, the building can be additionally finished. In this case, you can do both external and internal insulation of the cinder block walls of the house with your own hands.

Which side should I finish a cinder block house?

Thermal insulation can be both outside the walls and inside. If finishing is done using the first method, you can save space inside the building. Insulating a cinder block house from the outside will also require less costs effort, time or money.

How to insulate a cinder block house?

How to insulate a cinder block house from the outside? External finishing can be done with polystyrene foam. This material is easily glued using a special mixture. First, it is worth leveling the wall under it and priming it so that moisture does not seep through. So how to insulate a cinder block structure correctly?

To create thermal insulation inside, preparatory measures will be required. To do this, the surface is leveled and then primed. Such work can be done using plaster or putty mixture. The walls must first be cleaned of dirt or dust.

In order for the thermal insulation to last a long time, it is important to put a layer of waterproofing under the thermal material. This will help avoid condensation.

To finish the inside you will need:

Insulation. The thickness of the sheets should not be more than 5 centimeters.
Putty knife.
Glue.

Once the site is prepared, you can begin installing the slabs. The adhesive mixture must be prepared according to the instructions on the package. It is applied to the surface with a spatula. Then the insulation material is glued to the glue. In this case, there should be no air under the slabs.

Important! Glue should be applied only to the base, not the slabs. The thermal material itself must have a clean surface. The sheets fit tightly to each other after gluing. If there are gaps left, they can be blown out with foam or sealed with putty.

How to install insulation on cinder block walls?

Before you insulate a cinder block house, you need to choose a thermal insulator. Insulation of a cinder block house from the inside can be done different materials. Their installation has certain nuances depending on the type of insulation. It is important to know such points before starting the event.

Foam insulation

The difficulty of using this product is that its installation requires a level base. If it is a cinder block wall, then it will need to be pre-plastered and then primed. The surface must be free of dust or paint.

To prevent it from absorbing moisture, waterproofing must be placed underneath it. This will allow the insulation to last longer. Waterproofing will not allow condensation to form, and therefore the walls will always be dry.

To work you need:

Styrofoam.
Putty knife.
Glue.

Installation is simple. The prepared surface is covered with glue, and then the plate is attached there. Then the plate must be pressed to squeeze out the remaining air from under it. It is recommended to apply the adhesive exclusively to the wall and not to the sheet. Then all the gaps between the slabs are sealed with plaster.

Installation can also be done using plastic dowels. But usually inside the house they are glued using a mixture. The final stage will be finishing or painting.

This method is fast and practical. The main advantage is that there is no need to level the surface before laying mineral wool. The installation process is carried out on the frame. It can be made of wood or aluminum. Before strengthening, the tree should be treated with mixtures that will prevent it from rotting and will prevent the appearance of insects.

The frame consists of cells of a certain shape into which mineral wool is placed. Then the whole thing is covered with plasterboard on top and then finished off.

Sealing insulation

After laying the thermal material, it is important to check its sealing at joints, sockets, switches and other things. Air may enter into the cracks remaining in these places. To prevent this from happening, sealants are used. If the gaps are large, polyurethane foam is used.

Conclusion

A video on how to insulate a cinder block building from the inside or outside is below. You can use it to learn more about the insulation installation process. It is also worth noting that insulation with mineral wool will cost less than with polystyrene foam.

The advantages of mineral wool include the fact that it does not burn like polystyrene foam. Also, when smoldering, no harmful gases will be released into the air. The downside is that cotton wool can absorb moisture when communications leak. But here everyone must calculate their capabilities and strengths, and then choose based on this best option for myself.

In Russia it is gaining fast pace individual construction. From a large number building materials many people choose cinder block. A house made from this material can be built in a short time and, most importantly, is worth little money. The disadvantage of cinder block is its loose, porous structure. As a result, under the influence of temperature changes and moisture, it crumbles. To avoid this, a cinder block house is subject to internal and exterior decoration. In this article we will tell you how to insulate a cinder block house.

When choosing a cinder block for building a private house, be sure to ask what kind of filler the manufacturer uses. The strength of the material depends on the size of the fractions; the smaller they are, the stronger the cinder block. But even this does not negate the mandatory insulation of a cinder block house.

Insulation of a cinder block house

Facade plaster

When preparing to build a house, select in advance the material with which you will insulate the structure. To use any insulation, lay a wide base. This will give you the opportunity to work with any material, which can then be hidden under finishing brick.

If you could not foresee this, then the only way out is to decorate the walls with plaster or install siding on them. Do not forget that when using these materials, thermal insulation must be made from sheets of foam plastic or fiber insulation.

Siding finishing

Experienced craftsmen claim that exterior decoration, done according to all the rules, guarantees an economic effect of 70%, so in some cases interior decoration not required.

Note! If you are insulating a cinder block house immediately after its construction, then you should not neglect installing a vapor barrier layer indoors. Moreover, they need to insulate not only the walls, but also the ceiling.
Internal insulation

Install a vapor barrier layer and insulation on the outside of the ceiling. To do this, use polystyrene foam or mineral wool. The finishing of the external walls of the house does not require the installation of vapor barriers.

Note! If you built a house with a basement or basement, then their walls and ceilings also require the installation of vapor barrier and insulation layers.

Mineral wool is attached to the walls using plastic or wooden slats.

Painting or siding

Use of polystyrene foam

The most democratic and cheap option insulation of a cinder block house from the outside - installation of polystyrene foam boards, finishing it with plaster and subsequent painting. If you are dealing with an old house, then you need to do renovation work. Seal all cracks and uneven areas. Then you insulate the walls with foam plastic. Secure them with dowels 2 times larger than the thickness of the foam sheet.

A more modern insulation material is polystyrene foam, made from the same raw materials as polystyrene foam. The effect is produced by a different production technology. Both of these materials have the same thermal conductivity, but polystyrene foam has much lower water absorption. When insulating with this material, there is no need to install a vapor barrier layer.

Foam insulation technology with plastering

Stages of work on insulating a cinder block house:

Wall plastering work.
Foam fastening.
Installation of reinforced mesh.
Leveling, priming and finishing walls.
Painting.

Note! If your project involves painting the walls, then most likely you will need to use acrylic or silicone plaster, but the latter will cost you much more.

The advantage of acrylic plaster is that it is applied in color. Mineral plaster needs to be painted after application. Painting will have to be repeated every 3 years. Colored plaster It will last you a very long time; usually it is painted when you want to change the color of the house.

Insulation with mineral wool

If you have the financial means, insulate your house with mineral wool, which you then cover with siding.

Spray insulation

Insulation of the house is done in order to minimize heat loss. Manufacturers do not stop and are constantly searching for new insulation materials. One of these new insulation materials is polyurethane foam. You can use it in the form of insulating spray or filling.

The mixture, consisting of two components, is sprayed using special equipment and a gun. As a result, you will have a coating without seams; cold air will not be able to penetrate through it at the joints of the cinder blocks.

You can use polyurethane foam for external and internal insulation. In addition, the material, in addition to insulation, provides walls with a vapor barrier, increases the reliability of structures and protects wooden parts from rot. Polyurethane foam insulation, according to manufacturers, has a service life of 30 years.

How to insulate a cinder block house with your own hands - Proraboff.rf

Most often, the developer thinks about thermal insulation of a house made of cinder blocks with his own hands after the object is erected. This is largely due to the fact that cinder blocks vary greatly in their thermal conductivity.

This indicator can be in the range of 0.35-0.6 W/(m K). Thus, it is very difficult to determine in advance how well cinder blocks can insulate inner space.

Why does a cinder block house need insulation?

If we start from building codes, reflected in SNiP 02/23/2003, the normal thickness of walls made of cinder blocks can be considered only 1.5-2 m. But such thick walls are extremely expensive. Suffice it to say that for such a structure it will be necessary to build a massive and expensive foundation.

In order for the walls of a house made of cinder blocks to retain heat in the home, the best option would be to perform thermal insulation. Then you will be able to save money, provide conditions for a pleasant microclimate, and also make the house more aesthetically pleasing.

From which side should a cinder block house be insulated?

There are two fundamentally different options thermal insulation of the walls of a cinder block house. If you place the insulation on the inside, there will be a greater risk of condensation on the walls. This is due to the fact that the dew point will be between the insulation and the wall. As a result, the risk of condensation will increase significantly.

When placing insulation on the outside of a cinder block house, you will notice several advantages at once. With this method, there is a saving of usable space, a reduction in the risk of condensation, and an improvement in the appearance of the building. Usually the insulation is covered with a finishing cladding, which also protects the walls of the building. It follows from this that exactly external insulation is more suitable.

How to insulate a cinder block house

There is a wide range of thermal insulation materials suitable for protecting a cinder block house from the cold. External thermal insulation can be made with mineral wool, glass wool, expanded polystyrene or penoplex. Each of these materials deserves some attention.

1. Mineral wool and glass wool

Both of these thermal insulation materials are available in sheets or rolls. Glass wool and mineral wool are similar in their qualities, so they can be considered together. The most serious advantage of these insulation materials is considered to be low thermal conductivity, which is at the level of 0.041 W/(m K). High noise insulation is also a plus. The increased fire resistance of mineral and glass wool also benefits them.

But such insulation also has disadvantages. The most significant is low moisture resistance. The thermal insulation capabilities of materials deteriorate if they get wet. The process of laying mineral and glass wool is associated with great difficulties. And due to the fact that insulation materials can clump into clumps, their density over a large working area turns out to be different.

2. Expanded polystyrene and penoplex

There are differences between these insulation materials, although they are not too fundamental. Expanded polystyrene is called ordinary foam. It is produced in thick slabs. Penoplex is more durable and thinner with similar thermal insulation capabilities. The materials are not afraid of moisture and remain in excellent condition for a long time. But penoplex is more expensive than polystyrene foam.

The main advantages of penoplex are considered to be low thermal conductivity, amounting to 0.039 W/(m K), the ability to easily resist moisture, and ease of installation. There are options for expanded polystyrene or penoplex, which are fire resistant.

However, there are types of insulation on the market that easily catch fire. Another disadvantage is the low sound insulation of materials. The cheapest polystyrene foam can quickly disintegrate into granules and deteriorate from exposure chemical substances and can be eaten by rodents and insects.

How to install insulation on cinder block walls?

Depending on which thermal insulation material is chosen, the operating technology will vary. The specifics of handling each of the above-mentioned thermal insulation materials should be looked at separately.

How to work with mineral wool

Preparatory measures when using mineral wool consist of covering cinder block walls with a primer and plastering. Gaps and cracks must be completely sealed with plaster. There are several options for laying mineral wool. The simplest is the so-called “wet” method. It's worth taking it apart.

1. When the surface is completely prepared, a support for the first row of thermal insulation material is installed on the base. Thanks to it, you can protect the thermal insulation from rodents.

2. Preparation of the adhesive solution. It is better to use moisture-resistant mastic, which, after preparation, is applied to mineral wool slabs. Next, the insulation is applied to the surface of the cinder block wall. It is necessary to try to make the gaps between adjacent slabs minimal. If they are noticeable, an adhesive solution should be placed in them.

3. The fixed thermal insulation layer is covered with glue. A reinforced mesh is placed on it, which is additionally treated with an adhesive compound and left for a day to dry completely.

Having completed such work, the owner can begin decorative finishing. Plaster or putty is used for it, which is then painted in desired color.

How to work with polystyrene foam

There are no fundamental differences when working with mineral wool and expanded polystyrene. The sequence of events here is approximately the same as in the previous case. The wet method of fixing polystyrene foam to the surface of cinder blocks looks like this.

1. Preparatory work. Cinder block walls must be thoroughly cleaned, and any cracks present in them must be plastered. Next, the working base is primed and left to dry.

2. As in the previous case, the prepared adhesive solution is applied to the foam. Expanded polystyrene sheets should be placed on the surface of foam block walls with bandaging. Any gaps are filled polyurethane foam or adhesive composition.

3. When the foam is secured over the entire area, it can be additionally secured with dowels. Then the insulation layer is primed and covered reinforced mesh. To secure it you need to use a large amount of glue.

After completing such work, the owner can proceed to plastering the facade. Plaster gives cinder block walls better thermal insulation and makes them aesthetically pleasing.

By responsibly carrying out the described activities, the owner will receive excellent result. A cinder block house will be well protected from the cold. You don’t need to spend a lot of effort and money for this.

Insulation of a cinder block house from the outside, technology for performing the work

Cinder block is universal material, which allows you to quickly build a large stone house. At the same time, these huge blocks are not suitable for every climate, so it is often necessary for such houses to insulate the walls from the outside. This material is made from the so-called slag concrete - a mixture of cement and slag crumbs, which is formed when iron is smelted from ore. The slag itself is durable, porous, and the block itself has a sufficient number of holes to provide high-quality thermal insulation. Often due to a violation construction technologies the house does not meet the owner's expectations, so it is required to additional insulation. This is worth doing in any case, if only because it will result in significant savings on energy resources. This article will describe how to insulate a cinder block house, namely, the main steps, as well as materials and construction technologies.

Material selection

Let's look at the two main types of insulation that are most suitable for cinder block walls.

The first type is mineral wool or glass wool. Using this insulation, you can cover walls both outside and inside, and you can also use it to insulate floors in rooms on the basement side. It is stuffed either using special staples, or into a network of boxes, which are then sheathed on top with some material. The main advantage is that there are no pests in it, and the area closes very quickly. This a budget option, which is much more affordable than the next type of material.

The second type is foamy polymer materials, made in the form of sheets of various thicknesses. The most popular are polystyrene, polystyrene foam and penoplex. Experts often consider them to be one and the same material; the only thing that stands apart is ball foam, which is the cheapest of these materials for wall insulation. These materials are often used to insulate only the outside.

The second type is preferable, but usually people look at their financial capabilities. All these materials are good.

Selecting insulation thickness

Insulation of a cinder block house will be successful only when it is chosen correct thickness wall coverings. Exact calculations are quite complex, but based on experience, we can say that better thickness The external insulation of houses in Russia is 10 centimeters thick. In this case, it is necessary to take into account not only the thickness of the insulation, but also the thickness of its coating - plaster or sheathing panels. For the southern regions of our country, you can make a thickness of 5-7 centimeters. The best advice will be obtained from those who already use such a house and have lived in it for at least one winter. The thickness of the walls of the house also plays a role. A house made of slag concrete can also be cold due to an improper foundation, and then it will also have to be insulated, but this is a completely different area of work.

Before starting insulation from the outside or inside, it is necessary to check the walls for cracks or uneven filling of the seam, and correct all this, otherwise the procedure will not give the desired effect.

Step-by-step instruction

In order to insulate walls made of slag concrete, it is necessary to perform a series of works sequentially. Let's consider the order of work for sheet materials.

Preparing the walls outside. It is necessary to brush off the dust, remove lagging fragments with sandpaper, holes and potholes must be carefully leveled. After this you need to start priming. The primer must be viscous, otherwise the cinder block will absorb it, and then you will have to fork out for this simple step.
Applying glue and pasting the walls with sheets of material. You need to press the sheets tightly, and after the glue dries, you need to carefully coat all the seams.
Installation of fasteners. Using special dowels, foam sheets are pressed against the wall for greater insulation strength.
A fiberglass reinforced mesh is glued to the surface, which should be applied to the entire plane of the insulation. A special glue is used for it, and it is rolled out from rolls with a roller over the surface.
Applying a protective layer. It is usually a flexible, cement-based polymer mixture. The surface is leveled.
Plastering the surface. This is just a decoration; usually it does not carry any power load or thermal insulation functions.
As for mineral wool, a frame is assembled for quick fastening, which is filled with pieces of insulation, and then the entire frame is closed decorative finishing- clapboard, thin siding or even profile laminated iron sheets.

Insulation of cinder block walls

Today we will tell you how to insulate a cinder block bathhouse from the inside and why, contrary to the instructions of heating engineers, it is necessary to carry out internal work. Houses should be insulated from the street side using one of two methods. The cinder block is laid in one row; unlike brickwork, there is no air buffer zone, and as you know, air is the best heat insulator. The blocks are afraid of moisture and they are very cold, so you can’t do without insulation in tandem with special films.

Choosing material for cinder block walls

Without insulation, a cinder block house will be cold.

Before we talk about the method of insulating cinder block walls from the outside and inside, let’s decide on the materials:

In addition to thermal insulation materials, special films are used. Before insulating a cinder block house, let’s look at the types of films (membranes) that are used to protect thermal insulation. There are three types in total:

wind barrier - does not blow through, allows moisture and steam to pass through;
waterproofing – protection from moisture, allows steam to escape from the thermal insulation;
vapor barrier - does not let anything through.

It is important to lay the membranes on the correct side, otherwise they will not perform their tasks. In principle, the choice of thermal insulation largely depends on the conditions under which the thermal insulation will be used. For example, in a house or a bathhouse, because in the latter there is not only an increased level of humidity, but also very high temperatures, especially in the steam room. It is very important that the thermal insulation withstands high temperatures and does not emit toxic substances.

Modern quartz heaters for home, according to reviews, are very inert. They are positioned as economical, which is not entirely true, and appearance leaves much to be desired.

You can read about which heater is more economical for an apartment here.

Internal or external insulation

How to properly insulate a cinder block house: from the inside or the outside? We have discussed this issue more than once and once again we will repeat that, according to technology, thermal insulation should be attached from the street side. Only in this case, you do not risk, along with transferring the dew point to the inside of the wall, getting a result worse than before insulation. There are situations when you have to install thermal insulation inside, for example, in a steam room, because by insulating a cinder block bathhouse from the inside, you will protect the walls from moisture, which is also very important. Concrete blocks in conditions of high humidity will last much less.

region of your residence;
wall thickness.

There are many types of heaters for the home, which one to choose among this abundance? For residential premises, the best option is a convector.

Here it is written about why heaters on liquid fuel cannot be used at home.

How to insulate cinder block walls from the inside

The steam room in the bathhouse is insulated from the inside.

Internal insulation of a cinder block house is not recommended, unless, for example, you can use special paint with ceramic hollow spheres or penofol as additional thermal insulation. They are ineffective as independent materials. Thermal insulation of cinder block walls from the inside is practiced in steam saunas, when it is additionally necessary to protect the walls from moisture. In this case, the main thing is to prevent moisture from the steam room from getting into the insulation layer. Naturally, you can only use mineral wool. Work method:

a wooden frame is erected on the inside of the walls in the steam room;
Mineral wool, preferably basalt, is placed between the guides;
foil insulation is spread over the sheathing - it is very effective for saunas, as it blocks infrared radiation and does not allow steam to pass through;
a second tier of sheathing is installed on top of the foam foam;
A wooden lining is attached to the second tier.

Mineral wool needs to be laid in two layers and ensure that the joints do not coincide. The minimum insulation layer is 10 cm. The main thing is not to forget to glue the foam foam joints with special (not stationery) tape. Also, the ventilation gap between the penofol and the wooden paneling should not be neglected. Without it, reflective insulation simply will not work, and besides, the condensation on the foam foam must evaporate. Penofol foil often has small holes that are invisible to the eye. Therefore, to be on the safe side, you need to lay a vapor barrier membrane under the penofol.

External insulation method

Wet façade technique.

External insulation of a cinder block wall is performed using two methods:

wet facade;
ventilated facade.

Before you insulate a cinder block house from the outside, you should decide on a methodology to make it easier for you to figure out what will be more profitable. A wet facade is the application of plaster directly on top of the insulation. This method is possible using mineral wool or polystyrene foam (regular and extruded). The density of wool must be at least 50 kg/m. cube, foam plastic not less than 25 kg/m. cube, a larger error is welcome.

How to insulate a cinder block house from the outside using the wet facade method:

the wall must be smooth and primed;
The thermal insulation is glued to the wall and fixed with dowels;
a layer of putty is applied, a reinforcing mesh is embedded in it, a special plastic corner is used at the corners;
a second layer of putty is applied on top;
the surface is primed and painted.

Mineral wool is glued to universal dry construction adhesive, which must be diluted with water, and can also be used to putty. Polystyrene foam, in addition to such glue, can be attached to adhesive foam - similar to mounting foam, but intended for polystyrene foam boards.

Ventilated façade technique.

The ventilated façade technique involves constructing a structure from the outside, where the thermal insulation layer will be blown through. This is necessary to remove all possible condensation and for cooling, which is convenient in the hot summer. The technique can be used:

mineral wool;
polystyrene foam with its derivatives;
liquid thermal insulation;
ecowool.

First, the first level of sheathing is erected, then the thermal insulation stage. Mineral wool and foam plastic are glued, and ecowool, polyurethane foam and penoizol are sprayed onto the wall using a compressor. Afterwards, any film is laid, which should first of all be a wind barrier, and if it still does not allow moisture to pass through, this is only a plus. The next level of sheathing is built on top of the film, which is necessary so that there is a ventilation gap between the thermal insulation and the finishing. In the buffer air zone, flows always circulate from bottom to top, like an exhaust hood. Given this fact, special attention should be paid to the degree of flammability of the materials used. You should choose non-flammable insulation materials, which we already wrote about once.

Brief summary

Before you insulate a cinder block house from the inside, remember the parting words of heating engineers: “Only external insulation gives a good result.” Work inside is carried out only if it is necessary to protect the walls from the destructive effects of moisture, for example, in a steam room. In houses, internal thermal insulation can be an addition to the external one, nothing more. From the street side, a house can be insulated using two methods: wet and ventilated facade. Before work, always consider which layer of thermal insulation is needed specifically in your case.

Building a house from cinder blocks has a number of obvious advantages. Such construction is economically profitable, because the walls of such a structure are erected quite quickly.

However, when building a house from cinder blocks, you need to know how to insulate cinder block walls and perform this procedure as efficiently as possible.

Classification

Today there are two technologies for building insulation:

“wet” with plastering, which involves mechanical or adhesive installation of thermal insulation to the wall surface and subsequent laying of a reinforcing layer and a finishing decorative coating;
“dry” using a protective and decorative screen.

Insulation options

This is not to say that cinder block is a completely ideal material. It is characterized by some disadvantages. For example, the material does not tolerate dampness, especially with insufficient high-quality insulation. The structure freezes, and then, when it thaws, the cinder block can crumble. That is why it must be insulated. Today, there are several technologies that answer the question of how to insulate a cinder block house from the inside or outside.

Before starting work, you need to clearly understand: it’s just cold in the house, or the walls of the house are really freezing and damp. The process of insulating the outside of a building can be carried out using the methods described below.

Ventilated facade

The ventilated system consists of stacked elements connecting to a single façade structure. A high-quality system is characterized by the ideal placement of existing finishing elements located in the same plane with the facade.

In this case, the gap that forms between two adjacent panels can be minimal or pronounced. Installation of panels with gaps will allow you to hide various flaws in the work, as well as, if necessary, adjust the finishing elements.

Some types of systems provide 3D adjustment, thanks to which you can perfectly align the plane of each element relative to the adjacent one.

Using a special material, façade sealant, you can putty the seams between the ceramic tiles. After this, the seams must be covered with ceramic chips.

It is especially important to correctly calculate the thickness of the ventilation gap.

Note!
Different types of systems are able to provide gaps of different thicknesses.

This parameter directly depends on the thickness of the insulating material used. However, the limit norm is considered to be 100 mm; otherwise, too much traction occurs in the formed space. It is extremely undesirable in case of fire.

Note!
The minimum gap width that can provide effective ventilation of walls is 20 mm.
In the case of a one-story building, it is better to increase the gap to 4 cm, then the required volume of ventilation will be ensured.

The instructions for most systems for installing facades imply the following procedure:

surface marking;
fastening guides;
installation and fixation insulation material;
installing a windproof membrane on top of the insulation;
installation of sub-cladding structure;
laying facing material.

Note!
The insulation material must be securely fixed, otherwise the insulation boards are likely to slip, which will lead to the formation of cooling sections of the wall.

Two-layer mineral wool insulation materials are fixed with the harder side of the building, which ensures an excellent fit of the slabs with the soft side to the surface of the building wall. At the same time, the outer side of the structure will retain some rigidity.

Layered masonry

Also insulate a cinder block house with outside it is possible according to the method layered masonry . This technology involves the creation of a three-layer structure using effective insulating material between the surface of the load-bearing or self-supporting wall and facing material.

Since you can insulate a cinder block house from the outside using this method even with your own hands, a similar three-layer construction very popular.

In addition, it has a number of advantages:

small thickness and weight;
fire resistance;
unique appearance.

Layered masonry during insulation work often does not have external differences from monolithic brickwork. Therefore, experts consider such walls to be reliable and durable.

The most interesting thing is that apartments in houses whose facades are made facing bricks, are always in demand, because not many people understand that this house is not actually built of brick.

The layered masonry method stands out from other existing techniques:

simplicity of the set of materials;
standard installation method;
as well as the opportunity to carry out work year-round.

Warm facade

Facade systems as a method of implementation thermal insulation works for buildings is a multilayer structure and at the same time structural element structures

A cinder block house, unlike buildings made of other materials, has extremely low thermal insulation parameters, which is why the owners of such buildings need to insulate the walls from the outside as soon as possible.

This rule is especially relevant for houses in Russia, where, due to the harsh climatic conditions in winter time houses can freeze very much.

How to properly insulate buildings

When talking about insulation of any buildings and structures, we always share possible options thermal insulation into two types - insulation outside and inside.

For cinder block houses It is usually recommended to insulate walls from the outside, this is due to the fact that when insulating walls from the inside, the dew point located between the building structure and the thermal insulation may shift. Due to a shift in the dew point, moisture can accumulate on the walls, causing mold and mildew to develop.

Internal insulation of buildings has other disadvantages, in particular, due to the large thickness of the thermal insulation layer, the area will be reduced interior space, which is especially unpleasant for owners of small cinder block houses, where there is already a lack of living space.

For these and other reasons, it is customary to install a layer of thermal insulation on the outside.

Insulation materials

Currently there are many various options insulation of a cinder block house from the outside.

The most common insulation materials usually include mineral or glass wool, polystyrene foam, expanded polystyrene, extruded polystyrene foam, etc.

To better understand the advantages and disadvantages of these materials, you need to consider each of them separately.

Mineral wool and glass wool

Mineral wool and glass wool are common materials that can be used to quickly insulate any structure. Such products are made in two main types: in rolls and in the form of small slabs.

In terms of technical and operational characteristics, mineral wool and glass wool practically do not differ from each other, therefore their advantages and disadvantages can be described together.

The table below presents the most important advantages and the disadvantages of mineral wool and glass wool insulation.

Expanded polystyrene and extruded polystyrene foam

Extruded polystyrene foam differs from conventional polystyrene foam in production methods.

Extruded polystyrene foam has a denser and stronger structure and a lower level of moisture absorption. At the same time, extruded polystyrene foam is significantly more expensive, which seriously affects its popularity among owners of cinder block houses.

Expanded polystyrene of both types is usually produced in the form of slabs of various sizes, but today there are also products in rolls on the market.

The table below shows the advantages and disadvantages of both types of foam.

Advantages	Flaws
High-quality thermal insulation, the characteristics of which are better than those of mineral wool.	Low level of sound insulation.
Excellent moisture resistance.	Low fire resistance of individual products.
Don't lose yours performance characteristics when exposed to moisture.	Release of harmful chemicals during combustion.
Easy installation on smooth cinder block walls.	High fragility and destruction with minor mechanical impact.
Fire resistance of individual products.

Installation options for the insulating layer

To insulate a block house, it is not enough to simply purchase required amount insulation material, you still need to carry out high-quality installation.

Process installation work V block house will vary depending on the type of insulation chosen.

Installation of mineral wool insulation

Insulating a cinder block house with mineral wool is not the easiest task, but it can be done if you follow professional instructions. When using such insulation, the most popular method is wet installation.

To begin with, an owner who wants to insulate a house needs to prepare the surface for laying a layer of insulation; the walls must be cleaned of dirt, all cracks and irregularities must be plastered, after which a standard primer is applied.

In preparation for installation, it is also necessary to install the support base of the first row of insulation.

When preparatory work will be completed, you will need to prepare the required amount of adhesive solution for laying the insulation. The glue must be prepared in strict accordance with the manufacturer's instructions, which should be on the packaging.

The prepared glue is applied to each individual insulation board, after which it is installed on the wall surface.

It is important to remember that there should be no gaps between the individual insulation slabs, and therefore the slabs are laid either overlapping, or after laying the gaps are filled with separate strips of mineral wool.

After placing the insulation layer on the surface of the walls of the house, a special reinforcing, protective mesh is attached on top of it. After a day or more, you can complete the installation - plaster the surface of the insulation.

Installation of foam plastic

If it was decided to use expanded polystyrene, then this work will have a different sequence of actions, although many stages of the work will be very similar to wet laying of mineral wool.

First you need to prepare the walls - cleaning, sealing cracks and irregularities, after which the surface is primed.

At the second stage, the owner will need to prepare glue and apply a waterproofing layer, which are necessary to protect the insulating material from moisture. After this, the foam tiles are glued to the walls, and there should be no gaps or cracks between the individual slabs.

Glued polystyrene foam boards must be primed and a protective mesh secured to their surface. When the glued mesh dries, a primer will need to be applied to its surface again, after which putty can be applied.

Thanks to the application of putty, the owner can obtain a perfectly flat surface of the walls, which can be finished using various facing materials, to give the building the required appearance.
