Currently, they are often used to build houses. expanded clay concrete blocks. They contain sand, cement and expanded clay in a ratio of 1:2:3, respectively. All components are mixed in water and then harden naturally.
Expanded clay concrete is popular due to its light weight, which eliminates the need to build a massive foundation and also increases the speed of construction work.
Wall cladding with brick and mineral wool
Before putting a building into operation, the walls made of expanded clay concrete blocks must be insulated - and this can be done both from the outside and from the inside.
Brick facade panels
If you use expanded clay concrete for cladding walls outside for insulation purposes façade panels under a brick, this method will be very effective. This material has excellent insulating properties and is considered good insulation, as it perfectly maintains the temperature inside the building.
The disadvantage of this method is the high cost of the facing material - which is why brick facades are very rarely used for these purposes.
Mineral wool
There is another material for insulating a house or bathhouse made of expanded clay concrete blocks - mineral wool. Its use for finishing walls both outside and inside is more justified.
The material is different affordable price, has excellent thermal insulation properties. In the process of insulating expanded clay concrete walls, mineral wool is laid in two layers, and between them there must be wind protection and waterproofing.
If it is not enough to simply insulate the wall, and you need to additionally equip it with vapor-tight insulation, you can use a layer of aluminum foil. In this case, the insulation of a building constructed from expanded clay concrete blocks will be of higher quality and more efficient.
Features of use
In order for sheets of material to be securely held on a vertical surface, it is imperative to install a sheathing made of wooden beam and a special frame system.
According to the standards, the width of the installed sheathing should be 2-3 centimeters less than the width of the sheet of cotton wool. You also need to install anchors into the wall - sheets will subsequently be put on them mineral wool.
If you are insulating a building with uneven expanded clay concrete walls, it is advisable to use mineral wool, which has two layers of different densities. In this case, the material is attached to the wall with a soft layer so that it adheres better to the surface.
When additional wind protection for the walls is required, a horizontal sheathing is installed on top of the mineral wool sheets. A dense polyethylene film, and on top - the necessary facing materials.
To insulate the walls of a house or bathhouse at a certain level, it is better to use fiberglass. It can be equally effective for installation on both external and external internal surfaces from expanded clay concrete blocks.
To insulate the wall from the outside, glass wool is placed between its surface and a sheet of foam plastic. The latter retains heat well and has excellent insulating properties. When insulating the internal expanded clay concrete wall of a house, fiberglass is placed under drywall.
Before insulation is laid on expanded clay concrete blocks, the following work must be done:
- remove dust and dirt from the wall;
- dry the surface;
- plaster the walls.
Next, you will need to make holes in the base with a depth of 5-7 cm and a diameter of no more than 20 mm. Wooden plugs will be attached there, which will subsequently be additionally fixed with cement mortar. For this purpose
You can also use gypsum mortar.
At the next stage, metal slats, pre-impregnated with an antiseptic composition, are attached to the wooden plugs. The thickness of the slats should be equal to the thickness of the glass wool slabs.
The slats are placed on the surface at intervals equal to the width of the insulating boards. After installation is completed, slabs are installed to insulate the expanded clay concrete wall of the house.
Of course, the insulation of an expanded clay concrete house requires increased attention from the one who performs such work - first of all, attention should be paid to the thickness of the walls, which are made at forty centimeters - in two blocks, respectively. Before the start of construction, people try to figure everything out and ask themselves: is it necessary to insulate the expanded clay concrete blocks of walls from the outside?
There is another option, when the structure has already been erected, but in this case a lot of financial resources are wasted on heating. In this case, the owners begin to think about optimization external insulation. Next, it will be shown in detail how this should happen and what materials are best to use. Let's try to look at all kinds of insulation options in this publication.
How important is insulation?
Is insulation as important as they write about it everywhere on the Internet? There is a lot of information on the Internet - it’s no secret that not everything needs to be paid attention to. The vast majority of data, as a rule, relate to the topic and partially reveal it.
First of all, you need to choose the right insulation for expanded clay concrete walls - this is the basis, since success will directly depend on this.
Insulation of a wall made of expanded clay concrete blocks should be done gradually - you should not force things or try to quickly find a replacement for this material.
It’s safe to say that in this case, more money will be spent - this is facilitated by an increase in density of approximately ten centimeters.
An alternative to insulating expanded clay concrete walls from the outside is correct application budget options. The most common and, at the same time, budget option is laying with outside buildings - indeed, this may be an exception to the rule, but in this aspect maintaining tightness is not even discussed. Between the sheets of insulation remains free place- foam seams and holes polyurethane foam.
Is there a difference in the characteristics and thermal conductivity of different wall materials?
Possibilities for wall insulation
Naturally. Nowadays, the world of building materials is updated almost daily - insulating a house from expanded clay blocks from the outside good example. Technologies for insulating expanded clay concrete blocks of walls outside in different countries differ - for example, in Spain everything will be done far differently than in Russian Federation.
Modern insulation houses made of expanded clay concrete blocks are distinguished by increased reliability and durability in operation.
Additional advantages include resistance to frost temperatures and water resistance.
It is thanks to these characteristics that developers even at apartment buildings Such blocks are purchased in large quantities.
Which insulation to choose?
How to insulate expanded clay concrete blocks of walls from the outside with mineral wool, polystyrene foam or penoplex?
Professionals say that of all the above three options, it is advisable to choose. This material not only optimizes the insulation of a house made of expanded clay blocks from the outside, but is also completely safe for human health, since it contains exclusively environmentally friendly components.
Fire safety is also very important - the material does not burn, is perfectly able to withstand heat and external loads. If you decide to stick to mineral wool, then try your best the right places cover with a vapor barrier, protecting them from moisture and getting wet.
When insulating walls using polystyrene foam, you must be sure to remember the so-called “unpleasant surprises” - over time, rodents can grow in such material.
Fire hazard and moisture absorption are other disadvantages that often determine the choice of builders in favor of the same mineral wool.
A well-ventilated facade should always be covered with a grille - this is necessary in order to completely eliminate even the theoretical possibility of small animals and birds getting into the insulation. In addition to the low cost of the material, which was mentioned above, its advantages are simple installation and a light weight.
The density and strength of penoplex, in comparison with, is much higher. The slabs contain locks that minimize the formation of unnecessary gaps. Penoplex itself is lightweight and easy to install.
We humbly believe that this is the most the best option in order to efficiently insulate the walls of almost any home.

When constructing houses from expanded clay concrete, the walls are created from two layers of the described material. Often this is not enough to keep the house warm winter time of the year. That is why it is important to properly insulate the building. In order for walls made of expanded clay concrete blocks to reliably retain heat in a room, it is necessary to properly insulate it, taking into account the characteristics of the specific structure and the materials used.
Why is it worth insulating?
Expanded clay concrete is characterized by high strength and durability, so it is excellent for creating residential buildings. It is worth noting that the thermal conductivity of the described material is 3 times lower than the thermal conductivity of brick. But it is worth remembering that it is necessary to insulate expanded clay concrete house walls. This is due to several reasons:
- To give expanded clay strength, the material is created very dense, so heat passes through it quite quickly. Because of this, expanded clay concrete walls must be insulated from the outside.
- Walls made of the described material are easily destroyed under the influence of external factors. To protect the material, it is worth cladding and insulating the building from the outside. Often, facing bricks are used for this.
It is worth remembering that insulating walls made of expanded clay concrete blocks will not only help maintain more comfortable conditions in the house, but will also extend its service life, as it protects against condensation in the walls.
What materials should be used for insulation?
Before carrying out work on wall insulation, it is necessary to plaster the surface on both sides. This also helps keep the house warm. Insulation of expanded clay concrete buildings occurs using the following materials:
- Mineral wool. Many builders purchase this particular insulation, since it is not flammable and is made from environmentally friendly components. But when choosing this material, it is worth remembering that during insulation it is necessary to correctly create a waterproofing barrier. If this is not done, mineral wool will begin to deteriorate under the influence of moisture.
- Styrofoam. This material is lightweight and low cost. The foam is easy to attach without any help professional builders. It is worth noting that it is easily damaged by rodents and loses its properties when exposed to moisture. But when you create a reliable waterproofing barrier, you don’t have to worry about its destruction.
- Penoplex. This material can be installed quite simply with your own hands. At the same time, it is resistant to moisture and consists of environmentally friendly components.
How to insulate a house with mineral wool
All work on insulating a house made of expanded clay concrete thermal comfort blocks occurs as follows:
It is worth noting that polystyrene foam is not recommended due to the fact that it is a vapor-proof material, which can result in condensation on the walls. Installation of such material is carried out in the same way as fixing sheets of mineral wool. In order to properly insulate a building, before carrying out work it is worth finding out about the thermal conductivity of a particular structure.
Which method of external thermal insulation to choose?
When creating houses from expanded clay concrete, insulation is carried out in three ways:
- in-wall insulation;
- ventilated facade;
- thermal insulation using the “wet” method.
To understand which of the presented methods is more preferable, it is worth considering the features of each of them.
A ventilated facade is a method in which a frame is constructed, covered with facing material. In this case, the created structure carries an additional load on the wall. Due to the increased weight of the structure, using this method is not recommended.
In-wall insulation involves fixing a layer of insulation to the outside and the lining decorative material. This method is quite common, but it is worth noting that a fairly large amount of money must be spent on its implementation.
Wet insulation has the following advantages:
- helps create a protective layer that helps prevent weathering of expanded clay concrete blocks;
- does not create a large load on the walls of the building;
- allows you to choose one of many shades of the facade;
- when using this method it is spent a small amount of money.
It is worth noting that partitions in a house made of expanded clay concrete blocks are not insulated.
Selecting the type of insulation depending on the characteristics of the structure
If the façade of the house is not finished with anything, you can line the walls with bricks, having first secured the insulation. The effectiveness of this insulation method is quite high. But it is worth noting that this method is used infrequently. This is due to the cost of materials and time spent on cladding.
Also, buildings made of expanded clay concrete are often insulated in a similar way, but instead of brick, other facing materials are used. An example can be given metal siding. Polystyrene foam often acts as insulation.
Another one possible situation– a house made of expanded clay concrete is already finished with brick, but without a layer of insulation. In this case, you can treat the structure with polyurethane foam.
To do this, holes are first created in the wall through which the polyurethane mixture is supplied. After this, the material fills the cracks and hardens. The use of such material has many advantages. This material cannot be damaged by rodents and is not susceptible to moisture. But it is worth remembering that such material has a high cost. Because of this, many home owners abandon the described method in favor of cheaper options.

How to insulate a house made of expanded clay concrete blocks - Proraboff.rf
The technology for constructing walls made of expanded clay concrete usually involves laying them in two blocks. As a result, the thickness of the walls does not exceed 40 cm. This is completely insufficient to provide high-quality thermal insulation. Therefore, owners have to spend a lot of money on heating their home or endure not the most optimal conditions in winter.
Why thermally insulate a house made of expanded clay concrete?
It cannot be denied that expanded clay concrete blocks have many advantages. One of the most serious is strength. Expanded clay concrete allows you to build reliable and durable buildings without spending too much money. But in terms of thermal insulation characteristics, this material does not show itself in the best possible way.
If you install additional thermal insulation, you can significantly save on heating costs and reduce the thickness of the walls. It is advisable that materials with a thickness of at least 10 cm be used for insulation. The simplest method is to attach ordinary polystyrene foam to the façade side. But it is important to check that between sheet materials there were no stitches left.
How to insulate a house made of expanded clay concrete
Along with such an advantage as strength, expanded clay concrete blocks also show frost resistance and the ability to repel water. Due to this you can use different variants creating a thermal insulation layer. But in order for the insulation to still be of high quality and durable, with any method of creating it, the heat-insulating material must be outside protect with a vapor barrier. It is especially important that vapor barrier materials covered with insulation that can intensively absorb moisture. If there is a decent vapor barrier, the danger of reducing their thermal insulation characteristics will disappear.
What situations are possible
There are two device options expanded clay concrete masonry, which seriously affect thermal insulation measures. It is worth considering them so that you can choose the most successful method of insulating a house made of expanded clay concrete blocks.
1. There is no external cladding of the facade
It's about about the situation when they are dealing only with a wall made of expanded clay concrete blocks 40 cm thick. From the outside there are no facing materials. In this case, you can increase the thermal insulation capabilities of the walls by laying brick cladding. Then between the expanded clay concrete walls and brickwork it will be possible to place insulation.
Although the effectiveness of this insulation approach is very high, it is still rarely used. This is primarily due to the high cost of facing materials. It will not be possible to build brickwork yourself, and this forces the owners to incur additional costs. Therefore, they often turn to another method of thermal insulation of expanded clay concrete walls without external cladding.
A good option is laying insulation followed by installation cladding panels. The latter can be lining, plastic or metal siding, and so on. Foam plastic is quite suitable as insulation. But it needs to be laid in two layers, if the thickness of each is 5 cm. The foam is placed so that the seams of the second layer do not coincide with the seams of the first layer.
Once the insulation is in place, the siding is installed. Vertical guide profiles forming the frame must be laid under it. in addition to foam plastic, as thermal insulation material Mineral wool and other basalt insulation materials can be used. But such a thermal insulation layer must be protected with a vapor barrier.
And there is another method of insulation that can be implemented in in this case. It consists in covering the glued slab insulation with decorative plaster. Under slab insulation understand polystyrene foam, polystyrene foam or penoplex. They are easy to glue to the surface, then secured with dowels in the form of mushrooms.
2. The facade is additionally lined facing bricks
Most often, buyers of unfinished houses face this situation. In this case, the walls made of expanded clay concrete are additionally lined with brick. But there is no insulation in the layer between the materials. Then you can try treating the walls with polyurethane foam. The procedure begins with making holes in the wall. A polyurethane mixture is supplied through them, which then expands and fills all the cracks.
The use of polyurethane foam is associated with a large number benefits. This material is not afraid of rodents, copes with moisture, and cannot be affected by mold. The only difficulty is that this kind of material is expensive. Its laying should be entrusted to professionals who have special equipment. This also forces you to make additional expenses.
How to insulate a house made of expanded clay concrete
If the owner has chosen a method of performing thermal insulation, he will need to select a suitable insulation. An expanded clay concrete house can be protected from the cold by a variety of thermal insulation materials. These are considered the most successful.
1. Mineral wool
The most serious advantage of mineral wool is environmental friendliness. When insulating a house made of expanded clay concrete from the outside, this material is especially suitable. It is able to counteract the spread of fire and prevent heat loss. The most important thing is that in the process thermal insulation works The mineral wool was also covered with a vapor barrier.
2. Polystyrene foam when insulating the facade
The main advantage of polystyrene foam as a thermal insulation material is its low cost. But this insulation can burn and is often spoiled by insects. If you use polystyrene foam, you must cover the thermal insulation layer reinforced mesh. Then birds, small animals and other pests will not get to the insulation.
3. Penoplex as a material for insulation
To some extent, penoplex is similar to polystyrene foam. But it is more durable, copes well with moisture, is not interesting for insects, and it is very easy to install penoplex. There are no significant gaps left between adjacent slabs of such material. Experts believe that penoplex is best used to insulate the facade of a house made of expanded clay concrete.
Internal insulation of a building made of expanded clay blocks
Construction specialists agree that insulating expanded clay concrete house from the inside - not so much correct solution. The main reason to think this way is the risk of condensation on the walls of the building. This happens due to a shift in the dew point. Another obvious problem is that expanded clay concrete walls will begin to freeze.
It follows from this that for internal insulation It is better to use some kind of dense material that has a high vapor barrier. To ensure insulation and protection of expanded clay concrete walls from the inside, professionals advise using ordinary plaster. Both gypsum and cement mortar are suitable. But there are still differences between these materials.
1. Gypsum plaster. Its weight is less, and its thermal insulation capabilities are higher. But the obvious disadvantage is low adhesion gypsum plaster and expanded clay concrete. Therefore, the owner will first have to carefully prepare the surface.
2. Cement-sand plaster. It is well suited for insulating walls made of expanded clay blocks, since it has exactly the same composition as this material. In addition, cement-sand plaster adheres so well that it seals all the cracks present in the walls.
Using the most successful technology for insulating a house made of expanded clay concrete blocks, the owner will definitely receive excellent result. He just has to remember that high-quality insulation requires a careful approach. By choosing the wrong material or installing it incorrectly, the owner risks worsening the overall condition of the house and reducing its service life.

Features of insulating walls made of expanded clay concrete
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 of 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 a fairly large range of thermal 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.
Mineral wool
Scheme for insulating a wall made of expanded clay concrete blocks with mineral wool Mineral wool is fixed on in advance 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 the gluing is completed, the thermal insulation on the outside of the house is additionally fixed with plastic dowels. How to insulate an apartment on the ground floor 
Which basalt insulation better to choose for a frame house
Expanded clay concrete is a modern and very convenient to use building material for country houses. Building an expanded clay concrete house is not at all difficult. Such a building will be no less reliable than a brick one, and all the work will cost much less.
Expanded clay (burnt clay) and a mixture of cement and sand are used to make blocks. The clay filler makes artificial stones light and completely harmless to human body And environment. The structures turn out to be dry and well-breathable, since they are completely vapor permeable.
A mixture of concrete and expanded clay does not absorb moisture as well as foam concrete with similar properties. And moisture resistance directly affects thermal insulation abilities. Compared to brickwork, the thermal conductivity is one and a half times lower, and compared to foam concrete - almost two times lower (of course, walls of the same thickness are compared). When constructing one- and low-rise buildings Expanded clay concrete has been successfully used for several decades.
The size of one block is 7 times larger than bricks, but at the same time it has a mass 2.5 times less. Therefore, the work is completed quite quickly, and even a novice mason can handle it. Professionals can lay approximately 3 cubic meters of expanded clay concrete per day. Brick construction on average it goes three times slower.
Due to the size of expanded clay concrete blocks cement mortar It also requires significantly less than laying bricks. Depending on the installation method, the thickness of expanded clay block walls can be different. When building low (one- or two-story) houses in the southern regions, walls can be made no more than half a meter thick, but, however, only if there is exterior decoration insulation and plaster or facing stone.
For northern areas, where cold winters are a constant phenomenon, the walls should be thicker. For residential buildings, the optimal thickness is 80 centimeters. If the premises are non-residential and there is no heating in it, then a thickness of 20 centimeters and sheathing with insulation is quite suitable.
Due to the high strength of expanded clay concrete, it can be used to build multi-storey buildings, but, however, this will require additional reinforcement with steel rods.
Expanded clay concrete wall has a not very attractive appearance, therefore, even if external insulation was not planned, you should still think about exterior cladding. After all, this will also have practical benefits, since, despite the low hygroscopicity, the wall will certainly begin to crack and gradually collapse from temperature changes and freezing water in a couple of years.
Is it necessary to insulate the outside of an expanded clay concrete house?
At the moment, the construction of houses from expanded clay concrete blocks is gaining popularity. Let's try to figure out if this material is so good. Expanded clay concrete blocks have good thermal insulation, relatively inexpensive cost and low weight.
Using expanded clay concrete blocks as the main building material Your home is fully justified, however, despite all the worthy characteristics of this material, it is worth paying special attention to the insulation of the house from the outside.
Let's say frankly that the house needs additional external insulation, even if the expanded clay concrete blocks were laid in two rows. This is most relevant for areas where the temperature is predominantly low. If you don't pay attention special attention insulation, cracks may appear in the house, even if the quality of the blocks meets all standards.
In addition, finishing the outside of the house protects it from environmental factors, guarantees thermal insulation, waterproofing and soundproofing of the walls. If you only insulate a house from the inside, condensation will form between the insulation and the wall material, and this will, over time, lead to significant damage to the expanded clay concrete blocks.
Let's look at the most common methods of insulation.
Brick cladding
This method is very effective, since brick has high thermal conductivity, but entails quite high costs due to the considerable cost of this material.
Insulation with mineral wool
This method is certainly suitable for those regions where the weather is cold throughout the year. Cotton wool weighs a little, is inexpensive, easy to install, and at the same time provides excellent insulation. Additionally, you can install vapor-tight insulation with aluminum foil, then you will definitely not be afraid of any frost.
Foam insulation
This material is lightweight and can be used to insulate any building. Foam plastic is the most inexpensive material from modern insulation materials.
We decided that it is worthwhile to insulate a house made of expanded clay concrete blocks from the outside. Let's pay attention to additional aspects this question. It is important to pay attention to the protection of the insulation you have chosen from mechanical and atmospheric influences from the outside. For this, brick cladding is used, which we wrote about earlier, as well as such equally common materials as fake diamond, facade tiles, siding or plaster.
Artificial stone has a fairly reasonable cost, huge selection shades, but its characteristic disadvantage is its short service life.
Facade tiles are frost- and heat-resistant, and their cost is lower than that of some other facing materials.
Siding is also sufficient durable material, which is resistant to rotting, retains its original appearance, and is resistant to mechanical stress. The great advantage of this material is its low cost, ease of installation, and low repair and maintenance costs.
Lining is a thin cladding board made of wood, the characteristics of which directly depend on the type of wood. It should be noted that by itself wood material increases thermal insulation characteristics and looks beautiful from the outside.
It is obvious that insulation of an expanded clay concrete house from the outside is necessary in each specific case, because this material loses its properties over time. What kind of insulation to choose, how to decorate the outside of the house, is up to you to decide, guided by your financial capabilities, the climatic conditions in which you live, and aesthetic preferences.
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, heating the home will cost less funds, 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 if the outer walls are insufficiently thick and there is no heating, heating such a house in winter will be very expensive.
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 a very durable material, but it is not the warmest, unlike wood concrete 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.
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 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 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, taking into account 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, obliges to use fiber insulation on the façade to protect it from moisture.
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 by siding or facade plaster. The main advantage of expanded polystyrene boards is the low cost of the material and ease of installation. Foam plastic slabs are attached to the expanded clay block façade using dowel-fungi.
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 insulate a house made of 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 the blocks and bricks. Despite the effectiveness of this method, it is characterized by the complexity of the work and the high costs associated with paying 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.
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. The disadvantage of this solution is the reduction of 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 building walls, you can use inexpensive insulation - polystyrene foam or extruded polystyrene foam.
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.
