Insulation of the walls of an expanded clay concrete house. What is the best way to clad a house from expanded clay concrete blocks? Insulation for expanded clay concrete walls

Expanded clay concrete is laid in two rows, which corresponds to 40 cm. This thickness is not enough for the house to have thermal insulation properties. Without insulation, residents will have to intensively heat the house or endure unfavourable conditions life. To solve this problem, insulation is used. They come from different materials and install them different ways. Therefore, before proceeding to this stage, it is worth familiarizing yourself with all the variety of options.

How important is insulation?

Expanded clay concrete blocks have many advantages, they are alternative solution when looking for a material that is budget-friendly and durable. But they have their drawbacks - poor thermal insulation. With the help of insulation, this problem is solved, and heating costs are also reduced. For this procedure to be successful, you need to use at least 10 cm of insulation. And also make sure that there are no seams or gaps between the insulation sheets; if there are any, then you should foam them with polyurethane foam.

How is insulation carried out?

Expanded clay concrete blocks are frost-resistant and moisture-repellent. Based on this they use various options insulation. But so that the thermal insulation layer is installed efficiently and lasts long years, it is important to put a vapor barrier on top of it. This is how the vapor barrier absorbs moisture, retaining its properties completely.

Possible situations

It is easy to insulate a house from the outside using expanded clay concrete if you know the two main options for laying an expanded clay concrete block. It is important to study each one to choose the best one for your home.

There is no external façade cladding

Wall decoration with siding.

This means that there is nothing but two rows. Facade materials completely absent from the outside. In such a situation, when cladding a building with brick, it is possible to place insulation between the cladding and expanded clay concrete.

This is an effective thermal insulation measure, but it is used quite rarely. And all because the material for cladding the entire house will not be cheap. In addition, it is difficult to carry out such a volume of work on insulation with this material yourself. Because of this, one has to resort to outside help, which also costs extra.

More budget-friendly insulation options are made using panels. For example, lining, metal or plastic siding. Insulation in such situations is often polystyrene foam. This material is laid in two layers, provided that it is 5 cm thick. Place the panels on expanded clay concrete so that the seams of the first layer do not converge with the second. Next they lay the siding, and put it under it vertical profile, which forms the frame.

In addition to foam panels, mineral or basalt wool. But such materials require protection in the form of a vapor barrier. A glued slab heat-insulating layer is also used, and then covered with plaster. Plate insulation - polystyrene foam, polystyrene foam or penoplex. Easily attached to expanded clay concrete and then secured with dowels.

A fairly common situation when purchasing an unfinished building. Such a house already has a brick cladding, but there is no insulating layer between it and the kerazito-concrete one. To correct the situation, the walls are treated with polyurethane foam. This action is performed using holes in the wall through which the mixture is supplied. The polyurethane in these holes expands and fills the gaps.

With such insulation, it is protected from moisture, rodents, and mold. The only disadvantage of this procedure is the price. In addition, we need specialists to store this material, which also entails additional expenses.

How to insulate?

You can insulate a house made of expanded clay concrete using various materials, the most effective and affordable:

Mineral wool. It has high thermal insulation characteristics and is budget material. Provides protection for expanded clay blocks from moisture, dampness, and temperature changes. They are laid in two layers, between which a waterproofing and windproof layer is placed. Aluminum foil provides a vapor barrier.
Glass wool. Provides good thermal insulation in the house. It's environmentally friendly pure material, which is used to insulate both the outside and the inside of the house. In the first situation, the insulation is placed between foam plastic and expanded clay concrete, and in the second - between the wall and the gypsum structure. Plastering over insulating materials will enhance their properties.
Styrofoam. A budget option, but it is flammable and can be deteriorated by rodents. It is advisable to place it on top of the foam reinforced mesh so that birds and small rodents do not have access to it.
Penoplex. This material is similar to polystyrene foam, but it is not interesting to rodents, is more durable and repels water well. It is believed that penoplex is the best material for insulating houses.

The construction of houses from expanded clay concrete blocks is becoming quite popular. The material allows you to create a structure with excellent characteristics and at the same time spend little money (when compared with other materials).

The next issue after construction, which needs to be considered at the design stage, is insulation of the house; it will significantly help reduce heating costs. Next, we will consider the need to insulate walls built from expanded clay concrete, and also list the materials that can be used for thermal insulation of walls from the outside.

Is it necessary to insulate expanded clay structures?

The popularity of the material is due to its excellent strength and durability characteristics. It has thermal conductivity, which is almost 3 times lower than that of brick. But you should not neglect the insulation process of the walls of a house made of such material. There are 2 reasons for this:

Expanded clay is aimed at ensuring high structural strength. To do this, when making blocks, they try to make their structure as dense as possible, which facilitates the easier passage of heat through the walls. That is why the exterior finishing of the structure insulation material will help compensate for this deficiency.
Also, external atmospheric influences negatively affect this material. Of course, if you compare it with the same cinder block, then the resistance of expanded clay to frost is much higher. But this does not mean at all that frost does not destroy the material at all - this process occurs more slowly.

Insulating a house made of expanded clay will not only increase its energy efficiency, but will also significantly extend the service life of the structure.

From the above words, it becomes clear that insulation of a structure made of expanded clay concrete blocks should not be abandoned.

What thermal insulation materials should I use?

The first thing you need to do is plaster the walls on both sides, even if you plan to add additional insulation! This will significantly affect heat retention.

Let's look at the three main insulation materials that are most often used for wall insulation expanded clay concrete house:

Minvata. It is preferred, in most cases, for several reasons: the exterior decoration will be made of environmentally friendly, non-flammable and heat-resistant material. But it is worth remembering the need for waterproofing - mineral wool must be reliably protected from exposure to a humid environment.
Styrofoam. It is loved by many builders because of its ease, availability, simplicity and speed of installation. But it is also worth remembering its disadvantages: it is easily gnawed by pests, is fire hazardous and susceptible to moisture.
Penoplex. When insulating walls constructed from expanded clay blocks, it is worth paying attention to this material. It is easy to install, more resistant to moisture and rodents than its predecessor, and is environmentally friendly. Disadvantages include cost and high density, which does not allow the walls to “breathe”.

We insulate an expanded clay concrete house ourselves

Let's assume that the opinion of experts has been taken into account, and insulation will be carried out with dense mineral wool. The operating algorithm is approximately as follows:

Installation of polystyrene foam is carried out according to an absolutely similar principle: preparing the wall, priming, installing insulation, strengthening it, reinforcing it, painting or covering it with decorative panels.

The insulation of expanded clay concrete walls should be considered very important. To calculate the width of the insulation layer, use the thermal conductivity value of a particular structure based on the thickness of its external elements.

Insulating a house made of expanded clay concrete blocks from the outside worries many developers, since this material is increasingly popular in low-rise construction. In this article we will consider whether it is necessary to insulate expanded clay block walls 40 cm thick during construction or when the house has already been built. With an additional layer of thermal insulation, less money will be spent on heating the home, but insulating walls made of expanded clay concrete will require costs for the purchase of building materials.

Low-rise construction from expanded clay blocks has long been very popular. This material differs from foam block in greater strength and frost resistance, but expanded clay concrete also has a low thermal conductivity coefficient. But with insufficient thickness of external walls and lack of insulation strip foundation, heating such a house in winter will be very expensive.

Is it necessary to insulate a house made of expanded clay blocks?

Even before the construction of the house begins and during the laying of 40 cm expanded clay block walls, many decide to add additional insulation a private house to save on heating costs. Expanded clay concrete is very durable material, but is not the warmest, unlike arbolite and foam concrete blocks. Let's consider how and with what to insulate a house made of expanded clay concrete blocks with your own hands.

Comparison of insulation materials by thermal conductivity

To protect the facade and external walls of the house from freezing, a layer of thermal insulation of at least 10 cm is required. For these tasks, you can use polystyrene foam or mineral wool, which are attached to the facade with outside Houses. In the next chapter we will tell you how to independently insulate a house made of expanded clay blocks from the outside and inside, and what kind of thermal insulation is best to use in your work.

How to insulate a house made of expanded clay concrete blocks

Builders recommend insulating the facade of a house in a certain sequence - the lower the vapor permeability of the material, the closer it should be to the street in the insulation “pie”. Material with greater vapor permeability should be located closer to the heated room. But the most perfect option– build walls without insulation, using a thermal insulation calculator to calculate the thickness of the walls.

Insulation of a house made of expanded clay block mineral wool

Many developers believe that when insulating brick house or walls made of expanded clay block, it is better to give preference stone wool. The advantage of mineral wool over polystyrene foam is fire resistance and safety for human health. But the use of glass wool and basalt wool requires the use of a vapor barrier film to protect against moisture when laying fiber insulation on the facade.

Insulation of a house made of expanded clay block with polystyrene foam

When externally insulating an expanded clay block with polystyrene foam, it should be remembered that polystyrene foam should be protected from mechanical damage siding or facade plaster. The main advantage of expanded polystyrene boards is the low cost of the material and ease of installation. Foam boards are attached to the expanded clay block façade using polystyrene foam glue and dowel mushrooms.

Insulation of a house made of expanded clay block with penoplex

Extruded polystyrene foam is a dense and durable insulation material that is not afraid of moisture. Due to its characteristics, extrusion is ideal for foundations and insulation of the blind area of a house. Expanded polystyrene thermal insulation is best used from the street, since the material is fire hazardous, and high temperature releases substances harmful to humans - styrene.

Do-it-yourself insulation of a house made of expanded clay blocks

Let's consider several options for protecting expanded clay concrete blocks from freezing from the outside and inside. To insulate a house from the inside, do not use polystyrene foam; it is always better to insulate it from the outside. Whatever mineral wool manufacturer you choose, you should remember that the insulation must be protected vapor barrier film from the warm room side.

How to do it

If the house is laid out walls made of expanded clay block 40 centimeters without cladding, then you can insulate the house by laying insulation between the blocks and bricks. Despite the effectiveness of this method, it is characterized by the complexity of the work and at great expense related to the remuneration of professional masons. Let's consider a thermal insulation option that you can do yourself.

Insulation of expanded clay block walls from the outside can be done by cladding the house with slab thermal insulation and siding. Expanded polystyrene is attached to the facade using glue and is additionally secured in the corners with dowel mushrooms. A painting mesh is glued over the foam and the facade is puttied. When covering a facade with siding, you should first make guides from bars.

Insulation of a house made of expanded clay blocks from the outside

If expanded clay concrete walls are laid out at 40 centimeters with cladding, then there is only one way out - to insulate the expanded clay block wall from the inside of the room. Minus this decision is a reduction in living space and freezing of external walls. Expanded clay concrete will be exposed to frost, as a result of which condensation and mold may form between the insulation and the wall.

At the stage of building a house, you can fill the space between the brickwork and expanded clay block with polyurethane foam or ecowool. The disadvantage of using sprayed thermal insulation is the high cost of the material and the presence of special equipment. Therefore, when constructing walls you can use inexpensive insulation- polystyrene foam or extruded polystyrene foam Technoplex.

How to insulate a house made of expanded clay concrete blocks from the inside

Do not use thermal insulation inside a living space The best decision. In this case, the dew point will be between the insulation and the wall, which will certainly cause condensation. When designing, the dew point should always be avoided or set as close as possible to external wall. All this can be avoided if you independently insulate the house from expanded clay concrete blocks from the outside.

An online dew point calculator will help you calculate the thickness of thermal insulation and see where condensation occurs.

To reduce the thermal conductivity of expanded clay block walls, you can get by with facade plaster, which has an almost identical composition to expanded clay concrete. At the same time, the plaster levels the façade and closes all cracks and micropores in the masonry. You can also use thermal panels made of extruded polystyrene foam to insulate the facade.

Insulation of a house made of expanded clay blocks from the outside and inside

Insulating a house made of expanded clay blocks from the outside worries many developers, since the material is popular in low-rise construction.

How to insulate a house made of expanded clay concrete blocks

Preface. Most often, when building houses from expanded clay blocks, the walls are 40 cm thick, i.e. in two blocks. Even before the start of construction, many people ask themselves the question: is it worth insulating walls made of expanded clay block? The second option, when the house has already been built and a lot of money is spent on heating, the owners ask themselves the question - what is the best way to insulate a house made of expanded clay block? We will analyze these two options in this article and show a video lesson on how to insulate expanded clay concrete walls yourself.

Is it necessary to insulate walls made of expanded clay concrete blocks?

Most often during construction country house The walls are made of expanded clay block at 40 cm, i.e. in two blocks. Even before construction begins, many people ask the question: is it worth insulating walls made of expanded clay concrete blocks? The second option, when the house has already been built and a lot of money is spent on heating, the owners are already asking the question - what is the best way to insulate a house made of expanded clay block? how to insulate a house made of expanded clay block?

Options for laying walls from expanded clay concrete blocks

Alas, these blocks, although durable, are not the most warm material. The most important thing is that without insulation, heating a house will be much more expensive. In this case, the insulation must be at least 10 cm, for example, the most inexpensive option is polystyrene foam on the outside of the house, but everything must be airtight - the seams between the sheets of insulation should be carefully foamed with polyurethane foam.

How and how to insulate a house made of expanded clay concrete blocks from the outside

Comparison of thermal conductivity of wall materials

Modern building material in the form of expanded clay concrete blocks is reliable and durable.

TO additional benefits include frost resistance and water resistance. It is due to these characteristics that it is in great demand among developers.

Let's consider several options for wall insulation.

In any case, remember that the insulation must be closed with outside vapor barrier film. This rule especially applies to insulation materials that can absorb moisture from environment, at the same time their thermal conductivity characteristics increase, which is not at all to our advantage.

1. house walls 40 centimeters without external brickwork

You can insulate your house from the outside facing masonry, laying insulation between the expanded clay block and the brick. This is a more expensive insulation option. Despite its effectiveness, this method is not used very often. The problem is the high cost of the facing material and the complexity construction work, namely facing brickwork. Not everyone can do it efficiently, and the work of masons is quite expensive, so let’s consider the following option, which you can do yourself.

External insulation of expanded clay block house

The second method involves cladding the walls from expanded clay block on the outside PVC panels or siding, under which insulation is placed. Alternatively, you can lay 5-centimeter foam sheets in two rows so that the second row overlaps the seams of the first row (in a checkerboard pattern). The siding is attached to pre-installed vertical rails on the walls. You can also use basalt, roll insulation, protecting them with a vapor barrier from moisture.

And another option for insulating walls made of expanded clay blocks from the outside with your own hands is to line the house with slab insulation (expanded polystyrene or penoplex) and then apply decorative plaster on top of the insulation. The insulation on the walls is attached to adhesive composition, and additionally attached to the fungi. A mesh is glued on top and puttied decorative plaster. You can do this insulation option yourself.

2. house walls 40 centimeters thick with facing masonry

This problem can arise when you bought an unfinished house made of expanded clay blocks, where there is no insulation between the wall and the facing masonry, but only an air gap of 5 cm. Also, perhaps you built such a house yourself, but noticed that more money is spent on heating the house, than you expected, or more than your neighbors. In this case, you will need to think about how to insulate the facade of a house made of expanded clay concrete blocks from the inside with your own hands, or rather between the wall and the facing masonry..

Insulation of a house with facing masonry

If you bought an unfinished house where there is no insulation between the expanded clay block and facing bricks, then you can insulate the wall from the inside using polyurethane foam, which is poured between the walls in drilled holes. This insulation, after pouring, expands, like polyurethane foam, without forming gaps or cracks.

In addition, polyurethane foam is not afraid of moisture and rodents, which means your home is not afraid of rustling rodents between the walls; insulation will ensure the preservation of heat and protect the walls of the house from dampness, moisture and mold. The only disadvantage of such insulation is its high cost, and you won’t be able to insulate the walls this way on your own - you need special equipment.

Everything is much simpler if you are building a house yourself, then when building walls you need to put insulation between the walls. But what is the best way to insulate a house? in this case? - you ask. Most often, mineral wool, polystyrene foam or penoplex are used for these purposes. Let's take a closer look at these types of insulation for thermal insulation of expanded clay block walls with our own hands.

Insulation for expanded clay concrete facade of a house

Insulation of a house made of expanded clay block with mineral wool

According to professionals, of all the options for insulating a house made of expanded clay blocks, it is better to give preference to mineral wool. The main advantage of this insulation is safety for health due to environmentally friendly components. In addition, the material does not burn and retains heat well. When insulating expanded clay block walls with mineral wool, the insulation must be covered with a vapor barrier, protecting it from getting wet and moisture.

Insulation of the facade of a house made of expanded clay block with polystyrene foam

When insulating walls with polystyrene foam, you should remember that rodents can live in it; in addition, polystyrene foam absorbs moisture and is a fire hazard. The ventilated façade must mandatory be covered with a grill to eliminate the possibility of small animals and birds getting into the insulation. An additional advantage of polystyrene foam is the low cost of the material, ease of installation, and light weight.

Insulation of the facade of a house made of expanded clay blocks with penoplex

Penoplex more modern material, it is denser and more durable than polystyrene foam. In addition, penoplex is not afraid of moisture, is environmentally friendly and rodents do not live in it. The slabs have locks that minimize the formation of gaps, it is lightweight and easy to install. In our opinion, this is the best option for insulating the walls of a house built from expanded clay block.

How and how to insulate houses made of expanded clay concrete blocks from the inside

Use insulation for interior walls at home is not the best solution. Since in this case the dew point (the junction of cold and warm air with the formation of condensation) will be located between the insulation and the wall. Thus, the expanded clay block wall will freeze completely, which will not happen if you independently insulate the wall from the outside.

Insulation of expanded clay block walls from the inside

Today, builders advise insulating walls with materials in the following sequence - the higher the material’s thermal insulation properties, the closer it should be to the street, i.e. more cold material should be located closer to the heated room. To insulate walls made of expanded clay blocks with your own hands, you should make do with plaster. Wall mortar can be gypsum or cement.

Gypsum plaster is lighter and warmer. Before applying it to the walls, the surface is treated with concrete contact, which increases adhesion. Cement-sand plaster has the same composition as the wall material. This is why high adhesion is ensured. AND cement plaster, and gypsum mortar provide the walls of the house with equally effective thermal insulation from the inside. They close the micropores of the blocks, seal cracks and crevices.

How and how to insulate walls made of expanded clay block - video, instructions, Do-it-yourself insulation

Many people ask the question: is it worth insulating walls made of expanded clay concrete block? What is the best way to insulate a house made of expanded clay concrete block yourself? Let's answer this question in detail.

How important is insulation?

How is insulation carried out?

Expanded clay concrete blocks are frost-resistant and moisture-repellent. Based on this, various insulation options are used. But in order for the thermal insulation layer to be installed efficiently and serve for many years, it is important to put a vapor barrier on top of it. This is how the vapor barrier absorbs moisture, retaining its properties completely.

Possible situations

More budget-friendly insulation options are made using panels. For example, lining, metal or plastic siding. Insulation in such situations is often polystyrene foam. This material is laid in two layers, provided that it is 5 cm thick. Place the panels on expanded clay concrete so that the seams of the first layer do not converge with the second. Next, siding is laid, and a vertical profile is placed under it, which forms the frame.

Therefore for internal insulation Dense materials that have a vapor barrier are used in houses. Gypsum or cement plaster will help protect and insulate the wall from the inside. The mass of the gypsum solution is less, and the heat saving capabilities are higher. The only negative is that gypsum does not adhere well to expanded clay concrete blocks. To eliminate this drawback, you need to prepare the wall before work.

Insulating the house from the inside

Experts say insulating your home from the inside is not a prudent decision. Condensation may occur on the walls due to a shift in the dew point; in addition, the walls freeze.

Therefore, for internal insulation in houses, dense materials that have a vapor barrier are used. Gypsum or cement plaster will help protect and insulate the wall from the inside. The mass of the gypsum solution is less, and the heat saving capabilities are higher. The only negative is that gypsum does not adhere well to expanded clay concrete blocks. To eliminate this drawback, you need to prepare the wall before work.

Cement plaster is ideal for expanded clay concrete, as they have a similar composition. This plaster adheres well to the wall and seals all existing cracks.

We insulate an expanded clay concrete house ourselves

Let's assume that the opinion of experts has been taken into account, and insulation will be carried out with dense mineral wool. The operating algorithm is approximately as follows:

Insulation of a house made of expanded clay concrete

Insulation of a house made of expanded clay blocks from the outside

Expanded clay concrete blocks are becoming increasingly popular, especially for the construction of private houses. This building material, in fact, differs little from the well-known cinder blocks, the only difference is in the structural filler. Here, the latter is used as a porous material, expanded clay, which itself is often used for insulation. Therefore, expanded clay concrete has a fairly low thermal conductivity. Compared to ceramic clay bricks, expanded clay blocks retain heat 3 times better.

But, despite the fact that walls built from expanded clay concrete are quite warm, thermal insulation measures on the outside will not interfere with them for two reasons:

additional insulation (it hasn’t hurt anyone yet);
protection of expanded clay concrete walls from external influences.

Which method of external thermal insulation is best for expanded clay concrete walls

Today, three main methods of thermal insulation of houses outside are used:

ventilated facade;
in-wall insulation;
“wet” thermal insulation.

Now let's consider which of these methods is preferable for walls made of the described building material. It is worth immediately noting that expanded clay concrete is quite fragile and, at the same time, a hygroscopic material.

A ventilated facade, which involves the construction of a frame with some kind of cladding facing material, is a structure that carries a significant additional load on the wall. Considering that expanded clay concrete blocks are not particularly strong, it is better to exclude this method of insulating the outside.

The second method involves installing a layer of insulation on the wall outside (usually dense slabs mineral wool), which is then covered with decorative facing bricks. This method of insulation in itself is good, however, it is too expensive, both in terms of purchasing building materials and in paying qualified masons.

The third method of so-called “wet” insulation is perfectly suitable in our case, because:

protects expanded clay concrete blocks from weathering;
does not create large loads on the insulated surface;
allows you to create a unique color design facade;
least expensive in every sense.

Therefore, let's look at how to do such insulation on the outside of a wall made of expanded clay concrete.

Technology of “wet” facade using expanded clay concrete blocks

First, let's decide on the insulation. Expanded clay concrete is a porous, and therefore “breathable” material, so the heat-insulating agent must have the same qualities. According to this criterion, mineral wool, produced in the form of dense and durable slabs, is the best fit.

Sometimes polystyrene foam is used here, but it is not very good in this case, since, being a material with water-repellent properties, it is not capable of passing steam. Therefore, condensation formed from steam that passes through the wall from the side of the room will destroy the expanded clay concrete wall from the outside. Foam plastic, of course, is used for thermal insulation of such walls when guided by considerations of cost savings, because this insulation is the most affordable.

So, let's look at how to insulate a house made of expanded clay concrete blocks from the outside:

Prepare the surface of the wall, for which it needs to be cleaned of dust and treated with a high-quality primer for external use.
Now we prepare the glue, focusing on the recommendations written on its packaging. For mixing you will need construction mixer or a drill with an appropriate attachment. A properly prepared mixture should stick to work surface spatula.
The adhesive mixture is applied to a sheet of mineral wool like this. First, the entire surface on the glued side is covered. thin layer, after which a continuous slide of glue is formed around the perimeter. Two slides need to be made in the middle of the slab.
We begin gluing the mineral wool sheets from below from one of the corners. During installation, you should constantly monitor correct position each stove using a spirit level ( building level). It is better to install mineral wool sheets in a circle so that the glue in the underlying rows has time to stick. Adjacent horizontal rows should be positioned so that the vertical seams do not coincide (like bricks in masonry).
After 24 hours, the glued mineral wool slabs are secured with umbrella-shaped dowels. To fix mineral wool, you should use “umbrellas” with a metal core resembling a nail.
Now it’s time to reinforce the insulation surface. For this purpose, a special facade fiberglass mesh is used, which is sold in rolls of 50 meters. Its width is 1 m. It is installed vertically. To do this, the surface is first covered with a layer of plaster glue approximately the width of the mesh. Then, cut to size in advance, a piece of mesh must be pressed into the layer of applied mortar using a wide (50-60 cm) façade spatula. At the same time, the surface is leveled.
Next, the dried reinforcing layer is covered with another thin layer of special adhesive mass, primed and covered with some kind of façade decorative plaster. After all of the above layers have dried, painting is done.

It should be noted that if you decide to use foam insulation on the outside, the workflow is exactly the same. The only difference is the glue used for this.

The process of insulating a wall made of expanded clay concrete blocks from the outside does not present any major difficulties, but it is still better to entrust it to professionals who have done this more than once, since there are plenty of nuances in this work, especially when insulating with mineral wool.

How to insulate a house made of expanded clay concrete blocks from the outside: do it wisely

Expanded clay concrete blocks, having appeared relatively recently on the construction market, have occupied their niche. However, they did not become mega-popular.

In this article we will try to draw attention to their positive and negative qualities, use in housing construction and, most importantly, how and how to insulate a house made of expanded clay concrete blocks from the outside for comfortable living.

Description of material

Blocks, depending on strength and density, are: thermal insulation, partition, wall and facing.

Based on calculations, the recommended thickness of the walls of a building made of expanded clay concrete blocks is 40-60 cm. This is data for designing construction in the central region Russian Federation, including for the Moscow and Leningrad regions. The building material has numerous advantages.

non-flammable;
durable;
not subject to climatic fluctuations;
have a fairly low thermal conductivity coefficient;
environmentally friendly;
do not rot;
not susceptible to rodent infestations;
have high corrosion resistance;
convenient to use, easy to process;
are a good sound insulator.

Compared to other materials, buildings made from expanded clay concrete blocks are more budget-friendly, since their price is lower than that of foam and aerated concrete analogues. A wall built from expanded clay concrete blocks weighs three times less than a brick one. Therefore, there is no need for a strong foundation.

The production of these blocks is not difficult. The standard composition is expanded clay, cement, sand and water. The mixture is thoroughly mixed and compacted into molds using a vibrating machine.

When choosing a manufacturer, you should pay attention Special attention on the technology used to produce blocks. Since, in addition to the main components (which must also be of certain fractions and types, such as: cement of a grade not lower than M400, expanded clay no larger than 100 mm, fine sand), it is necessary to add components to the mixture that increase frost resistance, plasticity, and binding capacity (resins, lignosulfonate).

Drying the blocks takes at least a month.

Production of expanded clay concrete blocks

In principle, you can make blocks at home, many people add washing powder. But the quality of these products will remain on the conscience of the manufacturers, since only high-quality equipment can produce good material, having no extra voids.

Important! Expanded clay concrete blocks are available in different densities. You should definitely take this into account when choosing a material, especially for load-bearing walls.

During construction, it should be taken into account that the material is quite fragile and work on installing dowels should be carried out with extreme care. Block walls do not shrink. However, buildings from this material should not be built above two floors.

Insulation of the building

The question often arises: is it necessary to insulate a house made of expanded clay concrete blocks? Due to its porous structure, the material has relatively low frost resistance. Therefore, buildings made from such blocks require additional thermal insulation.

In addition, in addition to creating a comfortable microclimate in the house, with the help of insulation it creates additional protection from the influence of the external environment, as a result of which the durability of the structure increases significantly.
In this article we will look at how to properly insulate a house made of expanded clay concrete blocks from the outside.
To insulate walls, you can use three types of thermal insulation: mineral wool, polystyrene foam and extruded polystyrene foam (penoplex).
Experts do not recommend using the last two materials based on the following considerations. Polystyrene foam has poor vapor permeability. Vapors penetrating through walls turn into condensation and have a destructive effect on the structure. In addition, it is susceptible to rodents.
Penoplex, due to its density, does not allow walls to breathe and is quite expensive, but does not require additional waterproofing.
Mineral wool (both rolls and mats) is the best option for insulating walls made of expanded clay concrete blocks. It has numerous advantages: it is non-flammable, does not rot, is characterized by good sound and heat insulation, and does not suffer from rodents.

It is more correct to insulate a house made of expanded clay concrete blocks from the outside, since in this case the dew point will be on the surface of the building and the service life of the structure will increase.

How to insulate a house made of expanded clay concrete blocks from the outside

Insulation of the walls of an expanded clay concrete house Expanded clay concrete is laid in two rows, which corresponds to 40 cm. This thickness is not enough for the house to have thermal insulation properties. Without insulation, residents will have to...

It is important to ensure proper thermal insulation of the house. This will prevent premature destruction load-bearing structures and reduce heating costs. The building materials market now offers many products for creating wall fencing. They all have different thermal insulation properties. Next, we consider the question of whether insulation of expanded clay concrete external walls is necessary and how to carry it out.

Characteristics of the material from the point of view of thermal engineering

The thermal conductivity of a material strongly depends on its density. Among expanded clay balls the following classification can be given:

Comparative characteristics thermal insulation properties various materials

construction materials – density 1200 – 1800 kg/m3;
structural and thermal insulation – density 500-1000 kg/m3.

The thermal conductivity of structural materials is comparable to conventional ceramic bricks, therefore, according to heating engineering, the wall must have a sufficiently large thickness. Structural and thermal insulation types have characteristics similar to “warm” porous ceramics. In this case, the thickness of the walls of the house turns out to be smaller, but for private housing construction it can be further reduced through the use of effective insulation materials.

Materials for thermal insulation

Manufacturers now offer enough a large assortment heat insulators. To protect walls you can use:

mineral wool (slabs and mats);
Styrofoam;
extruded polystyrene foam (penoplex);
polyurethane foam;
ecowool;
“warm” plaster.

The most common of these methods are mineral wool and expanded polystyrene (foam plastic and penoplex). Their thermal insulation characteristics approximately equal.

Thermal calculation

When purchasing blocks, the manufacturer must always indicate their properties. The calculation determines the thickness; to perform it, a characteristic such as thermal conductivity will be required. There are two ways to perform this calculation:

"manually";
using special programs.

Reduced heat transfer resistance of a wall made of expanded clay concrete compared to other materials

It is not difficult to perform an independent calculation, but for a person who does not have a construction education, it can cause difficulties. It is best to use the simple Teremok program, which works in two modes:

calculating the thickness of one of the layers of the wall structure;
checking the heat transfer resistance if the thickness has already been selected.

To work with the software, you will need the following initial data:

thermal conductivity of expanded clay concrete blocks;
block width;
thermal conductivity of insulation;
insulation thickness (not needed if working with the program in the first mode).

Having selected the values, you can begin insulating the walls of the house.

Work production technology

First of all, you need to determine which side to fasten the material on. Insulating a wall made of expanded clay concrete blocks from the outside is the most competent solution. Work can also be carried out from the inside, but only if fixing the heat insulator from the outside will cause great inconvenience and lead to increased labor and financial costs.

The process of protecting walls with insulation depends on its type. For different materials, the technology has slight differences, so it is worth considering each of them separately.

Scheme for insulating a wall made of expanded clay concrete blocks with mineral wool

Mineral wool is attached to a pre-installed frame. The work should be done in the following order:

cleaning the wall surface;
fastening vapor barrier;
frame installation;
installation of insulation;
waterproofing;
finishing of the facade with provision of an air-ventilated layer, at least 5 cm thick.

The layer is needed to remove condensation from the insulation, which loses its properties when wet.

Foam plastic and penoplex

The fastening of materials is carried out in the same way. The order of the layers is the same as in the previous case, the only difference is that the installation of a frame and the presence of a ventilated layer are not required. Penoplex is resistant to moisture, so you can do without a vapor barrier. Fastening the outside wall of a house made of expanded clay concrete blocks is carried out simultaneously in two ways:

on special glue for polystyrene foam;
on dowels.

Scheme for insulating a wall made of expanded clay concrete blocks with polystyrene foam

First you should cut the sheets, then try them on for size. After this, glue is applied to the material. You need to glue the polystyrene foam with a bandage so that there are no long vertical seams. Once gluing is completed, the thermal insulation on the outside of the house is additionally secured with plastic dowels.

Expanded clay concrete blocks appeared on the market relatively recently as a building material, so not everyone knows about their qualities. Expanded clay concrete stands out among other building materials existing today for its strength, frost resistance, low thermal conductivity, quick erection and durability. Thanks to these many positive qualities it has earned its popularity in the construction market.

When using expanded clay concrete blocks in the construction of houses, an important question may arise - do the walls need insulation and what building material is better to choose for insulating a house made of expanded clay concrete. Let us consider in detail all the nuances of this issue.

Is it necessary to insulate a house made of expanded clay block?

Most often, when constructing the walls of a house from expanded clay concrete blocks, they are laid in two rows, due to which the thickness of the wall structure is 40 centimeters. To significantly save money on heating a house made of expanded clay block in winter time, the issue of thermal insulation of the wall should be decided in advance, even at the planning stage future design walls of the house, since expanded clay concrete is not the warmest building material when building walls. For walls 40 centimeters thick, in order for the thermal insulation to be of high quality, its thickness must be at least 10 centimeters.

What materials are used to make thermal insulation for a house made of expanded clay concrete blocks?

Insulating the facade of a house using mineral wool

Among experienced builders There is an opinion that it is better to use mineral wool to insulate an expanded clay concrete house. Its main advantages are safety for health, since it is made from natural mineral components. Mineral wool has low thermal conductivity and is also safe in case of fire. But when using it to insulate expanded clay blocks, it is necessary to protect it from moisture with waterproofing membranes.

Use of foam plastic as insulation for houses made of expanded clay concrete block

As thermal protection, you can use the most common and less expensive material - polystyrene foam. It must be mounted with glue from the outside of the wall, while tightly laying the expanded polystyrene boards, and, if necessary, sealing the formed seams between them with polyurethane foam. We must also remember that this type of insulation can be damaged by rodents and small birds. If it is used, the façade must be covered with siding or plastered to avoid damage. The main advantage of this type of insulation, such as polystyrene foam, is its low cost and ease of use.

Method of insulating a house made of expanded clay block with penoplex

Compared to expanded polystyrene, penoplex has a denser and more durable structure. Also, extruded polystyrene foam is safe for human health and is not affected by moisture. This material weighs little and is easily mounted on a façade made of expanded clay concrete. In our opinion, he is one of the the best materials for insulation of building structures.
Thermal insulation of the facade of a house made of expanded clay concrete blocks from the outside
There are several options for insulating a house from the outside, from the inside, and using facing masonry. Below we will consider all these options in more detail.

40 cm walls made of expanded clay block without facing masonry

From the outside, a façade made of expanded clay concrete can be insulated using facing masonry, i.e. lay polystyrene foam between the blocks and the brick, leaving a ventilated gap for ventilation. This method of insulation is effective, but highly costly due to the complexity of the work performed and the need to attract specialized masons. Therefore, in practice it is used quite rarely. There are methods for thermal insulation of houses made of expanded clay concrete blocks that you can apply yourself, without hiring qualified specialists.

One such option is to install polystyrene foam slabs with a thickness of at least five centimeters in two rows, so that the second row covers the joints of the first row. Then the siding is attached to the mounted vertical guides. As an insulating material, you can use not only polystyrene foam and penoplex, but also basalt mineral wool insulation, having previously taken care of their protection with a vapor barrier film.

And another way to insulate walls made of expanded clay concrete from the outside is to use polystyrene foam of the required density or penoplex and cover them with a layer on top facade plaster. After fixing the slab insulation to the glue with additional use dowel-fungi, the entire surface is covered with a painting mesh, and then puttied with decorative plaster.

Walls made of expanded clay concrete block with a thickness of 40 centimeters with facing masonry

If there is no insulation between the expanded clay blocks and the facing masonry, then to reduce heating costs in winter period time, it is necessary to insulate the walls from the inside. Polyurethane foam (PPU) can easily cope with this task. To do this, holes are drilled in the wall, and using a special installation, polyurethane foam is poured into them. After pouring inside the wall, polyurethane foam expands like polyurethane foam, and creates a continuous layer of insulation, replacing air gap. Using this method you can protect yourself from dampness and keep your house warm during cold periods. But this material has high cost and its use is only possible with the use of special equipment, which entails additional costs. This is the main disadvantage of using this method for insulating a house made of expanded clay concrete blocks with facing masonry. Therefore, even at the stage of erecting walls made of expanded clay blocks, you should not leave voids between the wall and the facing masonry, but immediately take care of insulation made of foam plastic or extruded polystyrene foam.

Methods for insulating a house made of expanded clay concrete blocks from the inside

Using thermal insulation materials from the inside as a finishing for expanded clay concrete blocks is not the best option, since there is a possibility of a dew point appearing in the wall. To prevent the wall from freezing and condensation and moisture forming on its surface, it is best to insulate it from the outside. But, if it is not possible to insulate expanded clay concrete blocks from the outside, then plaster can be used to insulate the house from the inside. In its composition, it is a dense material and has a high vapor barrier, which gives good insulation and protects walls made of expanded clay concrete blocks from the inside. Plaster can be either gypsum or cement-sand. There are differences in the use of these two solutions for insulating expanded clay concrete blocks. Let's take a closer look at which ones:

Gypsum plaster

This type of plaster has less weight, and accordingly its thermal insulation is higher. It should also be mentioned that gypsum plaster There is also a drawback, namely poor adhesion to a wall made of expanded clay concrete. To use it, you will need to additionally treat the walls with a primer, which will increase the adhesive characteristics of the gypsum plaster.

Cement-sand plaster

It is well suited as a material for insulating expanded clay concrete walls, since it has the same composition as expanded clay concrete blocks. Cement-sand plaster easily penetrates into existing structures expanded clay concrete blocks pores that creates perfect coverage and provides a good barrier against moisture penetration.

And in conclusion, let us remind you that in order to get good thermal insulation of a house from expanded clay concrete blocks and at the same time save money on heating in the cold season, you need to use only quality material for thermal insulation of the walls of the house, and also do not forget about the insulation of the strip foundation and the ceiling of the basement. To do this, you need to approach this issue very carefully and correctly. After all, when wrong choice thermal insulation material and violation of the rules and regulations for its installation, there is a high probability that the quality of the house will deteriorate and its service life will decrease.
