The house has a cinder block floor with insulation. How to insulate a cinder block house from the inside yourself? Curtain façade systems

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

For example, materials such as brick, concrete, cinder block and foam block do not look high quality in appearance. To give your home an aesthetic appearance this material subjected to further processing. Next we will describe, what is the best way to clad a house?.

There are many cladding options outer surface Houses.

Curtain facade

At its core curtain façade this is a false wall metal frame, which is located at some distance from the main wall. It is on this false wall that the finishing material is subsequently hung. The positive aspects include the fact that you can insulate the walls of the house with outside without taking up room space.

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

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

Despite the fact that vinyl siding is inexpensive and very practical way give the facade of the house decent looking, it should be said that plastic has an electrostatic property that attracts dust. In addition, metal or vinyl siding will not help you create an aesthetically pleasing home, as the striped appearance of this siding does not look good enough.

Market of fiber cement and ceramic panels offers you a wide range of textures and colors, various imitations of the structure of wood, timber or decorative plaster. You can find all this on the building materials market. Some varieties metal siding and porcelain tiles are not lagging behind in this race. IN in this case it is not possible to provide any specific recommendation. In some situations, it is worth proceeding from the guarantees offered by the manufacturer and from personal choice.

Natural and artificial stone for cladding

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

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

Decorative plaster mixtures

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

If you decide to insulate the walls, then insulating material is attached before the plaster, on top of which a mesh is applied to ensure high-quality fastening of the plaster. Particular attention should be paid to the paint, since paint that is not intended for the facade will fade and become faded over time.

Brick cladding

Brick cladding can also be used, but it requires many additional conditions. And you need to remember about it when creating a project for the house itself. If your foundation is poured without taking into account brick cladding, you may have difficulties in the future.

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

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

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

Why does a cinder block house need insulation?

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

So that the walls of a house made of cinder blocks can retain heat in the home, the most the best option thermal insulation will be performed. Then it will be possible to save money, provide conditions for pleasant microclimate, and also make the house more aesthetically pleasing.

From which side should a cinder block house be insulated?

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

When placing insulation on the outside cinder block house You will be able to notice several benefits at once. There are savings with this method usable space, reducing the risk of condensation, improving appearance the buildings. Usually the insulation is closed finishing cladding, which also protects the walls of the building. It follows from this that exactly external insulation is more suitable.

How to insulate a cinder block house

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

1. Mineral wool and glass wool

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

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

2. Expanded polystyrene and penoplex

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

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

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

How to install insulation on cinder block walls?

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

How to work with mineral wool

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

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

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

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

Having completed such work, the owner can begin decorative finishing. It uses plaster or putty, which is then painted in the desired color.

How to work with polystyrene foam

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

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

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

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

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

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

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

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

Insulation of a cinder block house

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

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

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

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

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

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

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

Painting or siding

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

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

Stages of work on insulating a cinder block house:

1. Wall plastering work.
2. Foam fastening.
3. Installation of reinforced mesh.
4. Leveling, priming and finishing walls
5. Painting.

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

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

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

Spray insulation

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

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

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

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

Choosing material for cinder block walls

Without insulation, a cinder block house will be cold.

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

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

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

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

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

Internal or external insulation

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

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

• region of your residence;
• wall thickness.

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

How to insulate cinder block walls from the inside

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

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

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

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

External insulation method

Wet facade technique.

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

• wet facade;
• ventilated facade.

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

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

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

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

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

Ventilated façade technique.

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

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

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

Brief summary

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

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

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

How to properly insulate buildings

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

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

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

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

Insulation materials

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

Among the most common insulation materials, mineral or glass wool, polystyrene foam, polystyrene foam, extruded polystyrene foam, etc.

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

Mineral wool and glass wool

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

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

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

Expanded polystyrene and extruded polystyrene foam

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

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

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

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

Installation options for the insulating layer

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

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

Installation of mineral wool insulation

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

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

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

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

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

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

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

Installation of foam plastic

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

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

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

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

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