Warming of expanded clay concrete house. Insulation of a house from expanded clay concrete blocks from the outside

Insulation of a house from expanded clay concrete blocks from the outside worries many developers, since this material is increasingly popular in low-rise construction. Consider in this article whether it is necessary to insulate expanded clay blocks 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 the insulation of 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 the foam block in greater strength and frost resistance, but at the same time expanded clay concrete also has a low coefficient of thermal conductivity. But with insufficient thickness of the outer walls and absence, it will be very costly to heat such a house in winter.

Even before the start of the construction of the house and during the laying of walls from an expanded clay block of 40 cm, many decide to additionally insulate private house to save on heating costs. Expanded clay concrete is a very durable material, but it is not the warmest, unlike wood concrete and foam concrete blocks. Consider how and with what to insulate a house from expanded clay concrete blocks with your own hands.

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

How to insulate a house from expanded clay concrete blocks

Builders recommend to insulate the facade of the house in a certain sequence - the lower the vapor permeability of the material, the closer it should be to the street in the "pie" of insulation. The material with higher vapor permeability should be closer to the heated room. But the most ideal option is to build walls without insulation, relying on the thickness of the walls.

Insulation of a house from claydite block of mineral wool

Many developers believe that when insulating brick house or walls made of expanded clay concrete block, it is better to give preference to stone wool. The advantage of mineral wool from expanded polystyrene is fire resistance and safety for human health. But the use of glass wool and basalt wool obliges, when laying fibrous insulation on the facade, to use it to protect it from moisture.

Insulation of a house from expanded clay block with polystyrene foam

When insulating an expanded clay block outside with foam, it should be remembered that expanded polystyrene should be protected from mechanical damage by siding or facade plaster. The main advantage of expanded polystyrene plates is the low cost of material and ease of installation. Foam plates are attached to the facade of expanded clay block with the help of dowels and fungi.

Insulation of a house from expanded clay concrete block with penoplex

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

Do-it-yourself home insulation from expanded clay blocks

Consider several options for protecting blocks of expanded clay concrete from freezing outside and inside. Do not use expanded polystyrene to insulate the house from the inside; it is always better to insulate the house from the street. Whichever mineral wool manufacturer you choose, it should be remembered that the insulation must be protected with a vapor barrier film from the side of the warm room.

How to insulate a house from expanded clay blocks from the outside

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 blocks and bricks. Despite the effectiveness of this method, it is distinguished by the complexity of the work and the high costs associated with the remuneration of professional bricklayers. Consider a DIY option for thermal insulation.

Insulation of walls made of expanded clay block from the outside can be carried out by facing the house with slab thermal insulation with siding. Expanded polystyrene is attached to the facade with glue and additionally fixed at the corners with dowels-fungi. A painting net is glued on top of the foam and the facade is putty. When cladding the facade with siding, you should first make guides from the bars.

If expanded clay concrete walls are laid out in 40 centimeters with cladding, then there is only one way out - to insulate the wall from the expanded clay block from the inside of the room. The disadvantage of this solution is the reduction in living space and freezing of the outer 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 brickwork and expanded clay block. The disadvantage of using sprayed thermal insulation is the high cost of the material and the presence special equipment... Therefore, when erecting walls, you can use an inexpensive insulation - foam or extruded polystyrene foam.

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

Use thermal insulation inside the dwelling - do not the best solution... The dew point in this case will be between the insulation and the wall, which will certainly cause condensation. When designing, the dew point should always be avoided or brought as close as possible to outside wall... All this can be avoided if you independently insulate the house from expanded clay concrete blocks from the outside.

Expanded clay concrete blocks relatively recently appeared on the market 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 coefficient of thermal conductivity, fast erection and durability. Thanks to these numerous positive qualities he earned his popularity in the construction market.

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

Is it necessary to insulate the house from expanded clay concrete block

Most often, when building walls of a house from expanded clay concrete blocks, they are placed in two rows, due to which the thickness of the wall structure is 40 centimeters. To significantly save financial resources for heating a house from expanded clay blocks in winter, the issue of wall insulation should be decided in advance, even at the planning stage for the future construction of the wall of the house, since expanded clay concrete is not the warmest building material for wall construction. 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 to make thermal insulation of a house from expanded clay concrete blocks

Insulation of the facade of the house with 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 health safety, as it is made from natural mineral components. Mineral wool has a low thermal conductivity and is also safe in case of fire. But when it is used to insulate expanded clay blocks, it is required to protect it from moisture with waterproofing membranes.

Application as insulation foam for houses made of expanded clay concrete block

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

The technique of warming a house from expanded clay block with penoplex

Compared to expanded polystyrene, expanded polystyrene has a denser and stronger structure. Also, extruded polystyrene foam is safe for human health and is not affected by moisture. This material weighs a little and can be easily mounted on a claydite-concrete facade. In our opinion, it is one of the best materials for thermal 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 with the help of facing masonry. Below we will consider all these options in more detail.

40 cm walls made of expanded clay block without facing masonry

Outside, the facade of expanded clay concrete can be insulated by using facing masonry, i.e. lay foam plastic between blocks and bricks, leaving a ventilated gap for ventilation. This method of insulation is effective, but highly materially costly, due to the complexity of the work performed and the need to attract specialized bricklayers. In this connection, in practice, it is rarely used. There are methods for thermal insulation of houses made of expanded clay concrete blocks that you can apply yourself, without hiring qualified specialists.

One of these options is the installation of foam plates 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 rails. As an insulating material, you can use not only expanded polystyrene 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 foam of the required density or foam with a coating on top of them with a layer of facade plaster. After fixing the slab insulation to the glue with the additional use of dowels-fungi, the entire surface is covered with a painting net, and then putty 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. This task can easily be handled by polyurethane foam (PPU). For this, holes are drilled in the wall, and using a special installation, polyurethane foam is poured into them. After pouring into the wall, the polyurethane foam expands like polyurethane foam, and creates a continuous layer of insulation, replacing the air gap. Using this method, you can protect yourself from dampness and keep the house warm during the cold period. But this material has a high cost and its use is possible only with the use of special equipment, which entails additional costs. This is the main disadvantage in the application. this method for house insulation made of expanded clay concrete blocks with facing masonry. Therefore, even at the stage of erecting walls from expanded clay blocks, you should not leave voids between the wall and the facing masonry, but immediately take care of insulation made of foam or extruded polystyrene foam.

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

The use of heat-insulating materials as a finishing of expanded clay concrete blocks from the inside is not the most the best option, as there is a possibility of a dew point in the wall. So that the wall does not freeze, and condensation and moisture do not form on its surface, it is best to insulate it from the outside. But, if there is no opportunity to insulate the expanded clay concrete blocks from the outside, then plaster can be used to insulate the house from the inside. By its composition, it is a dense material and has a large 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 a lower mass, and, accordingly, its thermal insulation is higher. It should also be mentioned that gypsum plaster there is also a drawback, namely poor adhesion to the expanded clay concrete wall. 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 with expanded clay concrete blocks. Cement-sand plaster easily penetrates the pores existing on the expanded clay concrete blocks, which creates an ideal coating and provides a good barrier against moisture penetration.

And in conclusion, we recall 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, it is necessary to use only high-quality material for thermal insulation of the walls of the house, and also not to forget about the insulation of the strip foundation and overlapping the basement. To do this, you need to very carefully and correctly approach this issue. Indeed, with the wrong choice of heat-insulating 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.

Question: Good afternoon, dear sirs! Please tell us how best to decorate the outside of the house from expanded clay concrete blocks (KBB), which facade will be appropriate here, what materials can be used?
Artur Shakarin, Novosibirsk

The answer is Semyon Fiskunov, CJSC Stroy-Alliance, Togliatti.

Answer: Hello Arthur! I will try to answer your question in detail. Moreover, KBB is a fairly popular material, many owners are made of expanded clay concrete blocks.

First of all, I would like to ask you a counter question - what is the thickness of the expanded clay concrete wall you erected? This is not an idle question.

It depends on your answer whether you have to insulate your walls from KBB, or you can immediately engage in fine external finishing and applying a decorative layer.

Insulation of walls from KBB

If you built the walls of the house from expanded clay concrete blocks in 1 block (this is 40 cm), then you will have to insulate it. For Novosibirsk and nearby regions, insulation of 150 mm of basalt wool or foam will be sufficient. This will give you a standard indicator for the thermal resistance of the enclosing structures R according to the new SNiP.

Ventilated facade on the walls made of KBB

If you have chosen a ventilated facade and, you can mount it in a wooden lathing or in the space between steel hangers. I do not recommend insulating a house from KBB with polystyrene foam under the ventilation facade.

Why? Because there are several reasons why polystyrene as insulation under the ventilation facade is completely unsuitable:

  1. Polyfoam is a combustible material and cannot be used in systems with a ventilated façade.
  2. Rodents feel great in such a cake, if you still make foam in the ventilation facade.
  3. The movement of air in the ventilation gap and the moisture removed will eventually make a set of individual foam balls from the foam sheets. Your insulation will fall down the ventilation gap.

Basalt wool, which you can use, is devoid of these shortcomings in the ventilation facade. You can also use polyurethane foam, rezole foam or ecowool.

After installing the battens or suspensions and subsequent insulation, you can mount the external decorative layer on the ventilation facade.

What is suitable in this case for a house from KBB:

  • Porcelain stoneware tiles
  • Clinker panels
  • Vinyl siding
  • Metal siding
  • Fiber cement panels
  • Planken
  • Block house

These materials can be shaped. How to mount them - see this site, everything is detailed.

Wet facade on the walls of a house from KBB

If you want to make a wet facade on your house, then after preparing the walls (leveling, filling cracks, removing excess mortar), you can start insulating the walls of the house.

You can use basalt wool of density from 45 and facade foam plastic of density from 25. Cotton wool is mounted on front dowels, foam is mounted on glue and additionally on front dowels.

At the time of installation of the insulation, a facade fiberglass mesh is attached on top of it, which will reinforce the plaster layer. The mesh is fastened with the very same front dowels with "fungi" that hold the insulation on the wall.

After installing the fiberglass mesh, a base coat or two-component plaster is applied. Further . Modern facade systems allow keeping the plaster layer in a semi-plastic state, which guarantees its long-term operation.

After priming, you can paint or paint.

You can use the following decorative coatings:

  • Painting with facade paint
  • Decorative plaster bark beetle
  • Plaster fur coat
  • Decorative smoked plaster

After applying the decorative layer, fixing compounds and facade varnishes can be used. They will protect the decorative layer from contamination and possible destruction.

PS. In no case should the house be insulated from expanded clay concrete from the inside. Expanded clay concrete is actually a vapor barrier material. Indoor moisture will be trapped between

Expanded clay concrete is a very durable material, but it is not the warmest, unlike wood concrete and foam concrete blocks. Consider how and with what to insulate a house from expanded clay concrete blocks with your own hands.

Comparison of heaters by thermal conductivity

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

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

How to insulate a house from expanded clay concrete blocks

Foreword... Most often, when building houses from expanded clay blocks, the walls are 40 cm, i.e. in two blocks. Even before the start of construction, many ask themselves the question - is it worth insulating the walls from 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 the house from expanded clay block? We will analyze these two options in this article and show a video lesson on how to insulate walls from expanded clay concrete on your own.

Do I need to insulate the walls from the expanded clay concrete block?

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

Options for masonry walls made of expanded clay concrete blocks

Alas, these blocks, although durable, are not the warmest material. The most important thing is that it will be much more expensive to heat the house without insulation. In this case, the insulation should be at least 10 cm, for example, the most inexpensive option is polystyrene from the outside of the house, but everything should be hermetically sealed - the seams between the heater sheets should be thoroughly foamed with polyurethane foam.

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

Comparison of thermal conductivity of wall materials

Modern building material in the form of blocks made of expanded clay concrete is distinguished by its reliability and durability.

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

Consider several options for wall insulation.

In any case, it should be remembered that the insulation must be closed from the outside with a vapor barrier film. This rule especially applies to heaters that can absorb moisture from the environment, while their heat-conducting characteristics increase, which does not suit us at all.

1.the walls of the house are 40 centimeters without external brickwork

It is possible to insulate the house from the outside with facing masonry, laying insulation between the expanded clay block and the brick. This is a more expensive option for insulation. Despite its effectiveness, this method is not used very often. The problem is the high cost of facing material and complexity construction works, namely, facing brickwork. Not everyone will be able to perform it with high quality, and the work of bricklayers is quite expensive, so we will consider the next option, which you can do yourself.

House from expanded clay block insulation outside

The second method involves facing walls from expanded clay block from the outside PVC panels or siding, under which insulation is placed. Alternatively, you can lay 5 cm foam sheets in two rows so that the second row overlaps the seams of the first row (staggered). The siding is mounted on 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 cladding the house with slab insulation (expanded polystyrene or expanded polystyrene foam), followed by applying decorative plaster over the insulation. The insulation on the walls is attached to the adhesive, and additionally attached to the fungi. A mesh is glued on top and putty with decorative plaster. You can do this option yourself.

2.the walls of the house are 40 centimeters long with facing masonry

Such a problem may 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 yourself built such a house, but noticed that it takes more money to heat the house, than you bargained for, or more than the neighbors. In this case, you will need to think about how to insulate the facade of a house from expanded clay concrete blocks from the inside with your own hands, or rather, between the wall and the facing masonry ..

House insulation with facing masonry

If you bought an unfinished house, where insulation is not placed between the expanded clay block and facing brick, then you can insulate the wall from the inside using polyurethane foam, which is poured between the walls into the drilled holes. This insulation, after pouring, expands, like polyurethane foam without forming gaps and cracks.

In addition, polyurethane foam is not afraid of moisture and rodents, which means that your house is not afraid of rustling rodents between the walls, the insulation will ensure the preservation of heat and protect the walls of the house from dampness, moisture and mold. The only drawback of such insulation is its high cost, and that it will not work to insulate the walls on its own - you need special equipment.

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

Heaters for expanded clay concrete facade of the house

Thermal insulation of a house from expanded clay block with mineral wool

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

Insulation of the facade of the house from expanded clay concrete block with polystyrene foam

When insulating walls with foam, it should be remembered that rodents can start in it, in addition, the foam absorbs moisture and is fire hazardous. The ventilated façade must be closed with a grill without fail to exclude the possibility of small animals and birds getting into the insulation. Their additional advantage of expanded polystyrene is the low cost of the material, ease of installation, light weight.

Insulation of the facade of the house from expanded clay blocks with penoplex

Penoplex more modern material, it is denser and more durable than expanded polystyrene. 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 crevices, 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 from 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 between the insulation and the wall. Thus, a wall made of expanded clay block will completely freeze through, which will not happen if you independently insulate the wall from the outside.

Insulation of walls from expanded clay block from the inside

Today builders advise to insulate walls with materials in the following sequence - the higher the thermal insulation properties of the material, the closer it should be to the street, i.e. colder material should be closer to the heated room. To insulate walls from expanded clay blocks with your own hands, you should do with plaster. The mortar for the walls can be plaster 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. That is why high adhesion is ensured. Both 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, close up cracks and crevices.

  • How and how to insulate walls from expanded clay concrete block - video, instructions, Do-it-yourself insulation


    Many people ask the question - is it worth insulating the walls from expanded clay concrete block, the better to insulate the house from expanded clay concrete block yourself? We will answer this question in detail.

How important is insulation?

How is the insulation done?

Blocks made of expanded clay concrete are frost-resistant and moisture-repellent. Based on this, apply different options insulation. But in order for the thermal insulation layer to be installed efficiently and to serve for many years, it is important to put a vapor barrier on top of it. So the vapor barrier absorbs moisture, retaining its full properties.

Possible situations

More budgetary options for insulation are made using panels. For example, lining, metal or plastic siding. Insulation in such situations is often polystyrene. This material is laid in two layers, provided that it is 5 cm thick. The panels are placed 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.

How to carry out insulation?

Insulation of the house from the inside

Therefore for internal insulation in houses, dense materials are used that have a vapor barrier. Gypsum or cement plaster will help protect and insulate the wall from the inside. The mass of the gypsum slurry is less, and the possibilities for saving heat are higher. The only negative is that gypsum adheres poorly to expanded clay concrete blocks. To eliminate this drawback, you need to prepare the wall before work.

Insulation of the house from expanded clay concrete. The importance of the procedure, insulation technology. The most popular materials for insulation: mineral wool, polystyrene, foam. Features of internal insulation.

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

Insulation of walls of expanded clay concrete house

Expanded clay concrete lies 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 unfavorable living conditions. To solve this problem, heaters are used. They come from different material and install them different ways... Therefore, before proceeding to this stage, it is worth familiarizing yourself with the whole variety of options.

How important is insulation?

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

How is the insulation carried out?

Blocks made of expanded clay concrete 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 to serve for many years, it is important to put a vapor barrier on top of it. So the vapor barrier absorbs moisture, retaining its full properties.

Possible situations

It is easy to insulate a house from the outside from expanded clay concrete, knowing the two main options for laying expanded clay concrete block. It is important to study each one in order to choose the best one for your home.

No external facade cladding

This means that there is nothing but two rows of expanded clay concrete blocks. There are no facade materials on the outside. In such a situation, facing the building with bricks, it is possible to place insulation between the facing and the expanded clay concrete.

This is an effective thermal insulation measure, but it is rarely used. And all because the material for cladding the whole 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, you have to resort to outside help, which is also worth the additional cost.

More budgetary options for insulation are made using panels. For example, lining, metal or plastic siding. Insulation in such situations is often polystyrene. This material is laid in two layers, provided that it is 5 cm thick. The panels are placed 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.

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

Facade with facing bricks

Quite a frequent situation when buying an unfinished building. In such a house there is already a brick cladding, but there is no insulation layer between it and the kerazite concrete. To remedy the situation, the walls are treated with polyurethane foam. This action is performed using holes in the wall through which the mixture is fed. The polyurethane expands in these holes and fills in the cracks.

With such insulation, the expanded clay concrete house is protected from moisture, rodents, and mold. The only disadvantage of this procedure is the price. In addition, specialists are needed to mortgage this material, which also entails additional costs.

How to carry out insulation?

You can insulate a house from expanded clay concrete with various materials, the most effective and affordable:

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

Insulation of the house from the inside

Experts say that insulating a house from the inside is not a prudent decision. Condensation may occur on the walls due to the displacement of the dew point, in addition to this, the walls freeze.

Therefore, for internal insulation in houses, dense materials are used that have a vapor barrier. Gypsum or cement plaster will help protect and insulate the wall from the inside. The mass of the gypsum slurry is less, and the possibilities for saving heat are higher. The only negative is that gypsum adheres poorly 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. Such plaster adheres well to the wall and seals up all existing cracks.

We insulate the walls of the house from expanded clay concrete outside

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 a little money (when compared with other materials).

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

Is it necessary to insulate structures made of expanded clay?

The popularity of the material is due to its excellent strength and durability characteristics. It has a thermal conductivity that is almost 3 times lower than that of a 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:

  1. Expanded clay is aimed at ensuring high structural strength. To do this, in the manufacture of blocks, they try to make their structure as dense as possible, which contributes to an easier passage of heat through the walls. That is why finishing the structure from the outside with an insulating material will help compensate for such a disadvantage.
  2. Also, external atmospheric influences negatively affect this material. Of course, if we 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.

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

From the above words, it becomes clear that you should not refuse to insulate a structure made of expanded clay concrete blocks.

What kind of insulation materials to use?

The first thing to do is to plaster the walls on both sides, even if you plan to re-insulate! This will significantly affect heat retention.

Let's look at three main insulation materials that are most often used to insulate the walls of an expanded clay concrete house:

  • Minvata. She is preferred, in most cases, for several reasons: the outside finish will be made of environmentally friendly, non-combustible and low-passable material for heat. But it is worth remembering the need for its waterproofing - the mineral wool must be reliably protected from the effects of a humid environment.
  • Styrofoam. It is loved by many builders because of its ease, accessibility, simplicity and speed of installation. But it is also worth remembering its disadvantages: it is easily gnawed by pests, fire hazardous and amenable to moisture.
  • Penoplex. When insulating walls built from expanded clay blocks, it is worth paying attention to this particular material. It is easy to install, more resistant to moisture, rodents and environmentally friendly. Disadvantages include cost and high density, which does not allow the walls to "breathe".

We insulate the expanded clay concrete house on our own

Suppose that the opinion of experts is taken into account, and the insulation will be carried out with dense mineral wool. The algorithm of work is approximately the following:

The installation of polystyrene is carried out according to a completely similar principle: preparation of the wall, priming, installation of insulation, its strengthening, reinforcement, painting or covering with decorative panels.

It is very important to take into account the insulation of walls made of expanded clay concrete. To calculate the width of the insulation layer, use the value of the thermal conductivity of a particular structure based on the thickness of its external elements.

Insulation of a house from expanded clay concrete

Insulation of the house from expanded clay blocks from the outside

Expanded clay concrete blocks are becoming more and more 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, expanded clay is used as the latter, which itself is often used for insulation. Therefore, expanded clay concrete has a rather low thermal conductivity. Compared to ceramic clay bricks, expanded clay blocks retain heat 3 times better.

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

  • additional insulation (it has not stopped anyone yet);
  • protection of expanded clay concrete walls from external influences.

What method of thermal insulation from the outside is better for expanded clay concrete walls

Today, there are three main methods of thermal insulation of houses from the outside:

  • ventilated facade;
  • in-wall insulation;
  • "Wet" thermal insulation.

Now let's consider which of these methods is preferable for the walls of the described building material. It should be noted right away that expanded clay concrete is quite fragile and, at the same time, hygroscopic material.

A ventilated facade, which involves the construction of a frame with its cladding with some kind of facing material, is a structure that carries a significant additional load on the wall. Considering that expanded clay concrete blocks do not differ in particular strength, it is better to exclude such a method of insulation from the outside.

The second method involves installing a layer of insulation (usually dense slabs of mineral wool) on the wall outside the wall, which is then lined with decorative facing bricks. This method of insulation is good in itself, however, too costly, both for the purchase of building materials, and for the remuneration of skilled bricklayers.

The third method of the so-called "wet" insulation is the best fit 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 take a look at how to make such insulation outside a wall made of expanded clay concrete.

"Wet" facade technology for 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 is the best suited, produced in the form of dense and durable slabs.

Sometimes foam is also used here, but it is not entirely good in this case, since, being a material with water-repellent properties, it is not able to pass 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. Polyfoam, 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 consider how to insulate a house from 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 outdoor use.
  • Now we are preparing the glue, focusing on the recommendations written on its packaging. For mixing, you need a construction mixer or drill with an appropriate attachment. A properly prepared mixture should adhere to the working surface of the spatula.
  • The glue mixture is applied to the mineral wool sheet like this. First, the entire surface from the side to be glued is covered with a thin layer, after which a slide of glue is formed around the perimeter. Two slides need to be done in the middle of the slab.
  • We begin to glue the sheets of mineral wool from below from one of the corners. During installation, you should constantly check the correct position of each plate 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 line up (like bricks in masonry).
  • After a day, the glued mineral wool slabs are fixed with umbrella-shaped dowels. To fix the mineral wool, you should use "umbrellas" with a metal core that resembles a nail.
  • Now it's time to reinforce the surface of the insulation. For this, a special facade fiberglass mesh is used, which is sold in rolls of 50 meters. Its width is 1 m. It is installed vertically. For this, the surface is first covered with a layer of plaster glue approximately the width of the mesh. Then, cut out in advance to size, a piece of mesh must be pressed into the layer of the applied solution using a wide (50-60 cm) facade trowel. In this case, the surface, at the same time, is leveled.
  • Further, the dried reinforcing layer is covered with another thin layer of a special adhesive mass, primed, and covered with some kind of facade decorative plaster. After drying of all the listed layers, painting is performed.

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

The process of insulating a wall made of expanded clay concrete blocks from the outside does not present strong difficulties, however, 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 with thermal insulation with mineral wool.

How to insulate a house from expanded clay concrete blocks from the outside: do it according to your mind

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

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

Material description

Blocks, depending on strength and density, are: heat-insulating, partition, wall and facing.

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

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

Compared to other materials, buildings from expanded clay concrete blocks are more budgetary, since their price is lower than that of foam and aerated concrete counterparts. A wall built of expanded clay concrete blocks weighs three times less than a brick wall. Therefore, no strong foundation is needed.

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 with the help of a vibrating table.

When choosing a manufacturer, you should pay special attention to the technology used for the production of blocks. Since, in addition to the main components (which must also be of certain fractions and types, such as: cement grade not lower than M400, expanded clay not larger than 100 mm, fine sand), it is necessary to add components that increase frost resistance, plasticity, binding capacity (resins , lignosulfonate).

Drying of blocks takes at least a month.

Production of expanded clay concrete blocks

In principle, blocks can be made at home, many add washing powder... But the quality of these products will remain on the conscience of the manufacturers, since only high-quality equipment can yield good material that does not have extra voids.

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

During construction, it should be borne in mind that the material is rather fragile and work on installing the dowels should be carried out with increased accuracy. Block walls do not shrink. However, buildings of this material should not be erected above two floors.

Building insulation

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

  • In addition, in addition to creating a comfortable microclimate in the house, with the help of insulation, additional protection is created against the effects of the external environment, as a result of which the durability of the structure is significantly increased.
  • In this article, we will look at how to correctly insulate a house from expanded clay concrete blocks from the outside.
  • For wall insulation, you can use three types of insulation: mineral wool, polystyrene and extruded polystyrene foam (penoplex).
  • Experts do not recommend using the last two materials for the following reasons. Polyfoam has poor vapor permeability. Vapors, penetrating through the walls, turn into condensation and have a destructive effect on the structure. In addition, it is susceptible to rodent influences.
  • Penoplex, due to its density, does not allow the walls to breathe and is quite expensive, but does not require additional waterproofing.
  • Mineral wool (both rolled 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 from expanded clay concrete blocks 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.
