Most often, the developer thinks about conducting thermal insulation of a house from cinder blocks with his own hands after the object has been erected. This is largely due to the fact that cinder blocks seriously differ in their thermal conductivity.

Such an 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?

Based on the building codes reflected in SNiP 23-02-2003, only 1.5-2 m can be considered normal wall thickness from cinder blocks, but such thick walls are extremely expensive. Suffice it to say at least that for such a structure it will be necessary to build a massive and expensive foundation.

In order for the walls of the cinder block house to be able to keep warm in the home, the most the best option thermal insulation will be performed. Then it will be possible to save money, provide conditions for a pleasant microclimate, and also make the house more aesthetic.

Which side to insulate a cinder block house?

There are two fundamental different options thermal insulation of the walls of the house from cinder blocks. If you place a heater with inside, there will be a great danger 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, several advantages can be noticed at once. With this method, there is a saving of usable space, a decrease in the risk of condensate formation, an improvement appearance the buildings. Usually, the insulation is covered with a finishing cladding, which also protects the walls of the building. From this it follows that external insulation is more suitable.

How to insulate a cinder block house

There is a large 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, polystyrene foam or foam plastic. Each of these materials should be given 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 similar in their qualities, so they can be considered together. The most serious advantage of these heaters is considered to be low thermal conductivity, which is at the level of 0.041 W / (m K). Also a plus should be called high sound insulation. The increased fire resistance of mineral and glass wool also benefits them.

But there are also disadvantages to such heaters. The most significant is the 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 heaters can clump together, their density over a large working area turns out to be different.

2. Expanded polystyrene and penoplex

The difference between these heaters is present, although not too fundamental. Expanded polystyrene is called ordinary foam. It is produced in plates of large thickness. Penoplex is more durable and thinner with similar thermal insulation capabilities. Materials are not afraid of moisture, they remain in excellent condition for a long time. But penoplex is more expensive than polystyrene.

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

However, there are types of heaters on the market that easily catch fire. Another disadvantage is the low sound insulation of materials. The cheapest styrofoam can quickly break down into pellets, deteriorate from exposure to chemicals, and be eaten by rodents and insects.

How to lay insulation on cinder block walls?

Depending on what thermal insulation material selected, the operation technology will be different. The specifics of handling each of these heat-insulating materials should be looked at separately.

How to work with mineral wool

Preparatory measures when using mineral wool are that the cinder block walls are covered with a primer and plastered. Slots and cracks must be completely sealed with plaster. There are several options for laying mineral wool. The so-called "wet" method is considered the simplest. 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 plinth. Thanks to it, you can protect the thermal insulation from rodents.

2. Preparation of the adhesive solution. It is better to use a 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 plates as small as possible. If they are noticeable, an adhesive solution should be placed in them.

3. Pinned thermal insulation layer covered with glue. A reinforced mesh is planted on it, which is additionally processed with a cool compound and left for a day to dry completely.

Having completed such work, the owner can proceed to decorative trim. For it, plaster or putty is used, which are then painted in the desired color.

How to work with Styrofoam

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. wet method fixing polystyrene foam on the surface of cinder blocks looks like this.

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

2. As in the previous case, prepared adhesive solution applied to the foam. Expanded polystyrene sheets must be placed on the surface of the foam block walls with dressing. Any gaps are filled mounting foam or adhesive.

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

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

Responsibly carrying out the described activities, the owner will receive an excellent result. The cinder block house will be well protected from the cold. To do this, you do not need to spend a lot of effort and money.

Houses built from cinder blocks, unlike their wooden and brick counterparts, need additional insulation from the outside. The thermal conductivity of the cinder block varies between 0.35-0.6 W / (m 0C), which means that in order to ensure normal temperature in a house in our harsh climate, it would be necessary to build a building from cinder block slabs with a thickness of about 1.5-2 meters, which is extremely unprofitable. That is why buildings made of cinder block slabs of standard thickness are additionally insulated from the outside.

External or internal insulation to choose? Professional builders it is recommended to insulate the cinder block house precisely from the outside, since after laying the heat-insulating layer inside the room, the dew point located between the coolant and the wall shifts. As a result, moisture will accumulate on the walls, contributing to the spread of moldy fungi.

Another downside internal insulation is that the heat-insulating material "steals" centimeters of the area of ​​​​the room. That is why it is rational to insulate a cinder block house from the outside.

materials

The most common materials for insulating a cinder block building are:

• fiberglass and mineral wool;
• extruded polystyrene foam and expanded polystyrene.

Pros and cons of mineral wool and fiberglass

Both types of these materials are produced in slabs and rolls. Operational and practical characteristics mineral wool and fiberglass are almost identical. That is why both of these materials will be considered together.

The main advantage of these materials is excellent thermal conductivity (about 0.041 W / (m 0C)) and sound insulation. One more indicator should also be noted - fire resistance. Mineral wool and fiberglass practically do not burn and spontaneously die out in the absence of an open flame.

The structure of fiberglass and mineral wool allows these materials to be laid even on uneven surfaces.

Perhaps the only drawback of these materials is that after getting wet they almost completely lose their heat-insulating and noise-insulating properties.

Extruded polystyrene foam

What is the difference between Styrofoam and Extruded Styrofoam? vernacular name extruded polystyrene foam - polystyrene. It has a fairly denser structure than polystyrene foam. It also practically does not absorb moisture. However, the cost of foam is higher.

Materials are produced in the form of plates (it is much less common to find expanded polystyrene in rolls).

Main advantages:

• a good indicator of thermal conductivity - 0.039 W / (m 0C);
• ease of installation;
• fire resistance - some types do not support the combustion process at all.

A significant disadvantage polystyrene boards is the low level of sound insulation.

Scheme of insulation with mineral wool

Mineral wool or fiberglass should only be laid on a previously primed surface. The best option in terms of speed is the so-called "wet" laying method.

First you need to prepare the surface - remove existing defects (cracks, chips) and primed. You also need to build a plinth that will serve as a support for the first base row.

The next step is the preparation of the glue. In this case, it is important to follow the instructions on the package. After the glue is prepared, you can proceed with the installation of the insulation.

Please note: the glue must be applied evenly on the insulation with a spatula, and not on the wall! During installation, you also need to ensure that there are no gaps between the plates.

Thermal insulation is glued in a checkerboard pattern, as brickwork. building level check the evenness of the masonry. Sheets of thermal insulation are additionally fixed to the wall with dowels-umbrellas. After the mineral wool has covered the entire wall, you need to lay a layer of glue, drowning the reinforcing mesh in it.

Wall insulation with polystyrene foam

Styrofoam laying is carried out in almost the same way as the installation of mineral wool.

The first step is surface preparation. Elimination of defects and application of a primer. Further, after preparing the adhesive solution, we proceed to the installation of insulation sheets.

Important: there should be no gaps between the plates!

After laying the insulation boards on top of them, you need to fix the reinforcing mesh. Further, this whole cake is carefully primed and puttied, after which you can proceed to the final stage - applying a decorative coating.

Building materials that are used to create a house require further processing.

For example, materials such as brick, concrete, cinder block and foam block do not look good on the outside. To give the house an aesthetic look given materials subjected to further processing. Next, we will describe what is the best way to decorate a house.

There are many cladding options outer surface Houses.

hinged facade

At its core hinged facade this is a fake wall metal frame, which is located at some distance from the main wall. It is on this false wall that the finishing material is subsequently hung. TO positive aspects refers to the fact that you can insulate the walls of the house with outside without taking up space in the room.

Also such insulation options are very relevant for cinder block houses. In addition, a large number of finishing materials are on the market, which also applies to positive aspects.

When facing, most often, use metal and vinyl siding, these are the most popular Decoration Materials . Ceramic panels and porcelain tiles are used much less frequently.

While vinyl siding is inexpensive and very practical way to give the facade of the house a decent look, it should be said that plastic has an electrostatic property that attracts dust. Also, metal or vinyl siding won't help you create the aesthetic look of your home, as the striped look of this siding doesn't look good enough.

The market for fiber cement and ceramic panels offers you a wide range of textures and colors, various imitations structures of wood, timber or decorative plaster. All this you can find in the building materials market. Some varieties of metal siding and porcelain tile are not far behind in this race. In this case, it is not possible to provide any specific recommendation. In a separate situation, it is worth proceeding from the guarantees offered by the manufacturer and from personal choice.

Natural and artificial stone for cladding

Natural and artificial stone the best materials for building cladding. The stone always and everywhere looked elegant and dignified. If you choose to use the stone as facing material you will never regret your choice. Of course, you can use a stone substitute, especially since today there are many of them, but they will never be able to “catch up” with natural material.

Marble or granite, shell rock or Dagestan stone, the choice is yours. The process of installation and application of facing material is not difficult. Artificial stone is similar in its characteristics to natural, however, it has a more affordable price..

Video: instructions for laying artificial stone with your own hands

Decorative plaster mixes

The most common material for exterior wall cladding. This method facade cladding is quite simple and not expensive. Sandy plaster is applied to the surface of the walls, on top of which a layer of decorative mixture is placed, creating a relief surface of the wall. Next, the paint is applied.

If you decide to insulate the walls, then an insulating material is attached to the plaster, on top of which a mesh is applied to high-quality fastening plasters. Special attention you should pay attention to paint, as paint that is not intended for the facade will burn out over time and become faded.

brick cladding

Brick cladding can also be applicable, but it requires many additional conditions. And it must be remembered when creating the project of the house itself. If your foundation is filled without taking into account brick cladding, you may run into trouble later on.

Don't forget that you can always just paint your cinder block house. Using a special facade paint, you can give your home a bright and unforgettable look.

Questions about how to insulate a cinder block house from the outside and why from the outside, and not from the inside, may arise after the construction of the house. The fact is that the indicators of heat preservation of cinder block structures are significantly inferior to buildings made of brick or wood. Therefore, houses made of this material need additional insulation.

The answer to the second question is obvious. Internal thermal insulation walls will reduce the area of ​​\u200b\u200bthe living space, which will not happen with the outside. And, besides, with this method of insulation in the cold season, water condensate will settle on the walls. And this is fraught with the appearance of molds, which are very difficult to fight. For these reasons, insulating a cinder block house from the outside is much more correct and cost-effective than insulating walls from the inside.

Materials for insulation

How to insulate the outside walls of a cinder block house? It is clear that any owner wants to spend the optimal amount of money on the thermal insulation device and finish the job as soon as possible. On the construction market can be purchased various materials with good thermal insulation properties and suitable for facade work.

What materials are suitable for external insulation of a cinder block wall? Currently, the following types of materials are mainly used for these purposes:

• foam plastic (extruded polystyrene foam), polystyrene foam, foam plastic;
• glass wool (fiberglass and mineral wool).

Each of these materials has both advantages and disadvantages. These materials have low thermal conductivity, so they provide good heat retention. Most importantly, they do not support combustion, so they are not fire hazardous. However, some types of styrofoam release toxic gases when burned. chemical substances, therefore, if they ignite, poisoning is possible.

Styrofoam is the most popular heat insulator. Low cost material and ease of installation allow it to be used in the construction of houses for more than 80 years. Styrofoam has weaker soundproofing properties compared to fiberglass. But he is not afraid of dampness. Even in high humidity conditions physical properties this material is virtually unchanged. It is convenient to mount foam plates on flat surfaces, so work takes little time. However, the plates themselves are quite fragile, so care must be taken when working with them. Small rodents are able to gnaw through foam, they are happy to arrange their home inside such a heat-insulating layer.

Penoplex plates are more durable and resistant to mechanical damage. Rodents and insects will never get into them. But the cost of the material itself is much higher.

Mineral wool consists of inorganic fibers, which are made from the melt of rocks, slags and mixtures of sedimentary rocks. Glass wool is made from glass waste. It consists of limestone, soda, sand, borax and dolomite. These materials are absolutely non-combustible. The advantages of glass wool insulation include high sound insulation. In addition, this material is convenient for filling cracks and voids. The structure of glass wool allows it to be applied even on uneven surfaces. But the technique of installing glass wool insulation is more complicated. The disadvantage of this material is wetness. When moisture gets on the fiberglass, the heat and sound insulation performance is significantly reduced.

How to insulate walls from the outside with fiberglass?

Before installing thermal insulation, it is necessary to prepare the walls of the house. If there are large cracks or voids in the walls, they are filled with mounting foam. It will take about a day for the foam to dry. Then the surface of the walls is leveled with plaster using a plumb line and a level. At the same time, all microcracks will be closed. A primer is applied to the plastered walls.

Then a starting profile or plinth is constructed, on which the first row of glass wool will subsequently fall. To do this, first, with the help of a level, mark all the outer corners of the building and connect them with one line. The width of the starting profile or plinth should be slightly wider than the thickness of the insulation boards. After that, vertical guides are attached to the entire height of the walls. The distance between them is made slightly smaller than the width of the roll or plate. This is done so that the insulation fits snugly between the guides.

The next step is to prepare the glue according to the instructions on the package. When using fiberglass, it is more convenient to apply the adhesive to the wall. Warming the house is best done in stages. First, one wall is closed with insulation, then the sheathing is mounted or fastened reinforcing mesh putty is applied over it. Then another wall is insulated.

How to insulate walls with foam?

Preparing the wall for foam sheets is carried out in the same way as for glass wool. All cracks are closed, and the surface of the wall is leveled with plaster. Then a primer is applied to dry plaster and an adhesive solution is prepared. When working with foam or foam boards, it is better to apply glue to the boards themselves. In this case, the coverage area should be at least 80% of the plate area. The sheets of insulation are glued in a checkerboard pattern, carefully making sure that there are no gaps between them. If gaps are found after installation, they are sealed with mounting foam or glue. On the fixed foam sheets, a layer of glue is applied in an even layer and a reinforcing mesh is glued. After the glue has completely dried, a regular or decorative putty is applied to the mesh.

Despite the need for additional insulation, building a house from cinder blocks has its advantages. The cost of a cinder block house is much lower than building the same area from brick, and even more so from wood. It takes much less time to build a cinder block house, due to the fact that the cinder block is much larger than a brick. The material itself has relatively good soundproofing properties. If you use a high-quality cinder block, then you can not spend money on facing the house.

However, houses made of cinder blocks have their drawbacks. Since it's pretty heavy construction material, the foundation for it must be made stronger than for brick or wooden house. Fresh cinder block, according to some experts, is able to allocate harmful substances. Therefore, before starting construction, it is recommended to keep the cinder block for fresh air at least half a year. Cheap varieties of cinder block have a gloomy grey colour, therefore, a house made of such material must be plastered both inside and outside. If the cinder blocks are damp, they can crumble, therefore, among other things, buildings made of this material need good waterproofing. Despite all the shortcomings, cinder blocks are widely used, especially in the construction of country or country houses.

Recently, a lot of information has appeared on the Internet on the insulation of houses with foam plastic. So I decided to share my experience of such construction and wall insulation with foam plastic. This method of wall insulation makes it possible to save on building materials when building walls. Since it is enough to build a not very thick wall in brick (25 cm) or cinder block, shell rock (20 cm) of the wall and then insulate the walls with foam plastic 50 mm thick and a density of 25 kgm3 (which replaces 50 cm of brickwork) and then plaster with an adhesive mixture of ceiresite ( Ceresit) with subsequent painting. External wall insulation with foam plastic does not require any special preparation.

1. Styrofoam with a thickness of 5 or more centimeters2. Solution adhesive mixture(Ceresit) for attaching tile insulation to the outer surface of building envelopes; 3. Reinforced mesh with fiberglass 4. Painting corners for corners and slopes5. Special dowels (umbrellas) for attaching foam plastic, about 5-6 pieces per m2. When I built a house for three years, the question arose of how to make walls so that I would spend a minimum on materials but at the same time that the house would be warm.

I consulted with friends on the Internet and decided to build the walls of the house with shell rock and insulate them with foam. After the construction of the walls and roof, he began to insulate the walls with foam plastic. To begin with, I determined the area and bought polystyrene foam with a thickness of 50 mm and a density of 25 kgm3. The most a big problem arose with the choice of glue, there were a lot of tips and recommendations, but I settled on the Ceresit CM 11 adhesive mixture, since it was the cheapest of all the recommended mixtures.

Although, realizing that the cheap ones are not the best, I nevertheless decided on Ceresit CM 11, which for 2.5 years and 2 winters justified my hopes .. So far, not one sheet of foam plastic has fallen off and the plaster has not crumbled, although this winter was such that the walls were hung with ice after rain with wind and then a sharp frost ..

Most often, the developer thinks about conducting thermal insulation of a house from cinder blocks with his own hands after the object has been erected. This is largely due to the fact that cinder blocks seriously differ in their thermal conductivity.

Such an 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 the interior space.

How to insulate a house from foam blocks?

Any private house needs insulation, regardless of the material from which it is built. The question "How to insulate a house from foam blocks?" more and more often you can hear on construction forums and websites.

When insulating foam blocks with sandwich panels or XPS-plates, you need to use special dowels for their fastening. The joints of the plates are carefully sealed to prevent moisture from entering the space between the plate and the foam block. The thickness of the layer of insulated material should be 1.2 - 1.4 times less than with insulation concrete walls the same thickness. When insulating with stone or mineral wool, do not use waterproofing materials to ensure normal moisture convection.

If the wall consists of two layers of foam blocks, between which a layer of insulation and waterproofing is laid, then external insulation is not required. An exception may be rooms with a large window area or doorways, for example, garages and verandas.

In any case, there are no universal solutions, because everything depends on climatic conditions, the purpose of the building and methods of heating it, the presence of a basement or semi-basement, external wall cladding and other factors. Only a specialist can give exact recommendations regarding the insulation of a house from foam blocks.

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 to insulate the walls from the outside for such houses. This material is made from the so-called slag concrete - a mixture of cement and slag crumbs, which is formed during the smelting of iron from ore.

The slag itself is strong, porous, and there are enough holes in the block itself to provide high-quality thermal insulation. Often due to violation construction technologies the house does not meet the expectations of the owner, so it is required to perform additional insulation. It is worth doing in any case, if only because it will result in substantial energy savings. This article will describe how to insulate a cinder block house, namely, the main steps, as well as materials and construction technologies.

Material selection

Consider two main types of insulation that are most suitable for cinder block walls.

The first type is mineral wool or glass wool. With this insulation, you can cover the walls both from the outside and from the inside, they can also insulate the floors in the room from the basement side. It is stuffed either with the help of special staples, or in a network of boxes, which are then sheathed on top with some material.

by the most economical option external insulation of a cinder block house is foam plastic and plastering work followed by painting. If the cinder block walls have already survived more than one winter and have slightly crumbled and become covered with cracks, then you should first deal with puttying such irregularities. Then, with dowels, which should be 2 times longer than the thickness of the foam, attach it to the wall. The minimum foam density is 10 cm, but 25 cm is better.
