It is absolutely no important in which house you live: it can own a country house, cottage, apartment in a high-rise building and other facilities. Always want to live in warmth and comfort, for which it is necessary to take care of the trimming of the house with insulating materials. If the walls are properly insulated correctly, you do not have to worry that they will be freezed in the cold, heat in your home will be preserved at the maximum.
How to insulate a house with a foam?
Especially not to do without insulation, if your home is erected from BRUSEV, because they are not able to save heat, as a result of what the heating of the house in the winter cold will have to be uploading decent amounts.
So that the insulation of the house does not flew into a penny, it became popular to use foam. The foam not only is cheap, but still has such advantages:
- low weight;
- unimpeded breathability;
- able to suppress noise;
- has a high level of thermal resistance;
- no moisture is afraid;
- Easy to work and decorating.
Since the warm house is a guarantee of correctly completed installation of insulating material, then in the article we will tell how to insulate the house of the foam making everything with their own hands quickly and efficiently.
What is the foam?

First of all, I would like to draw your attention to that the foam is a material in which there is no vapor permeability, it is strictly forbidden to use it for the premium of the room from the inside.
The density of foam is also very important. The most suitable density variant should be about 25. If you decide to insulate the walls not so dense material, it is likely to injure surfaces, and too dense material will lead to unjustified financial estates, because excessive density will not affect the thermal insulation characteristics.
The third, no less important point is the thickness of the foam, from which the quality of surface insulation directly depends. It is best to use the penplex with a thickness of 50mm, but you can buy and thicker material, no one forbids you, and the thickness of 100mm also has the right to exist. Using a thicker foam, prepare for what you will see a higher price category. To avoid rapid and unnecessary financial investments, you can attract experienced masters that will hold the right calculations and select the optimal option for your climatic belt. When calculating, they will take into account such indicators:
- average temperatures;
- the thickness of the walls that you plan to seize;
- Material from which those walls are manufactured and much more.

The comparative characteristic of the conventional foam with extruded is shown in the table below.
Foam characteristic | Styrofoam | Extruded Styrofoam |
Water absorption for 1 month. | four% | 0.4% |
Water absorption for 1 day | 2% | 0.2% |
Parp permeability | — | 0,018 mg / s.ch.pa |
Thermal conductivity | 0.036-0.05 W / (m * c) | 0.028 W / (m * c) |
Tensile strength | 0.07-0.2 kgf / m2MP | 0.4-1 kgf / m2MPA |
Compressive strength | 0.05-0.2 MPa | 0.25-0.5 MPa |
Density | 15-35 kg / m3 | 28-45 kg / m3 |
Operating temperatures | -50o + 70 ° C. | -50o + 75os. |
As can be seen from the table, it is more appropriate to warm the house with extruded foam, the technical features of which in many indicators are superior to the usual sheets of foam.
Without what can not do while working with expanded polystyrene?
Warming house foam with her own hands
Before heating the house outside the extruded foam, it is necessary to acquire building materials and devices, without which it is impossible to do in such a matter. Working with polystyrene foam you need:
- Perforator;
- sharp knife;
- several different spatulas;
- Plastics dowels with a wide hat;
- glue;
- reinforcement;
- rule;
- putty for work outside the house;
- priming;
- Metal spacers;
- Decorative material for the design of the facade.
Technology insulation at home
Warming at home by foam independently
The insulation of the wooden house is a foam, like any other construction, requires high-quality surface preparation.
It is very important to properly prepare the surfaces:
- Remove the old finishing material;
- Clean the surface;
- close the depressions and clean the bulges;
Of course, the perfect surface you absolutely do not need, but strong damage and defects are also not allowed, because they will not let the right surface and can form the cold bridges.
Then, the surface will be properly prepared, you can proceed to it impregnating with a primer solution. The primer must necessarily be a deep action, which will increase the level of adhesion with the mounting glue.
At the next step, you can produce direct insulation of surfaces by extruded penplex.
For such work, you need to dissolve the adhesive mass with water follows instructions. The mass should be well sweetered without dry breasts, and the consistency should be homogeneous, not too thick, but not too liquid - it is better that the thickness reminded the consistency of sour cream.

To apply the mounting glue with your own hands, you can use a spatula with teeth, but do not rush to cover the entire surface to them. It can dry very quickly, and you will not be able to process the territory properly.
So that the construction of the structure outside the expansion of the outside the polystyrene was performed correctly, observe such a sequence of actions:
- Cover the wall with glue (the wall area must correspond to the size of the foam sheet);
- lay out the insulation;
- Apply glue under the second sheet of foam and so on.
Such a priority suggests that it is very important that the sheets fit gradually, and the junctions of the canvas were carefully lubricated with glue.
So that the insulation of the house outside the penplex was done correctly, control the mechanism of plates.
So that the sheets are most firmly held on the walls, they can not only be tightly pressing to the surface of the walls, but also fix special fasteners. For these purposes, it is better to choose a dowel that you need to enter into a wall by 50 mm, and even deeper.
So that the fasteners did not fall into the insulation, it is worth getting a metal spacer. Before screwing a dowel, in the foam you need to pre-make holes with a perforator or drill.
Please note that you do not need to make a strong foam, because it can crack from excessive effects.
When the insulation of the building from the outside will be completed, it will be necessary to attach reinforcement on the wall. To do this, you better cut it on the strip of the same size, which correspond to the length of the walls. Then a wide spatula to distribute glue over the surface under one mesh strip, lay it on the surface and dissolve the spatula to avoid the catch. Apply the next lane of the reinforcement of the brass, it will avoid cracking the material at the joints.
The cover of the house of the penplex requires the finishing finish, because the unprocessed reinforced surface looks not very attractive, and the constant impact on her natural cataclysms will damage the integrity and quality of the finish.

A decorative plaster or paint can be used as an finishing finish outside the house. But before applying them to the surface, the wall need to be ochpace.
Tips and recommendations
Warming house foam
Before you begin to sow your home outside insulating materials, read such guidelines for work:
- To qualitatively, to see the house and save as much money as possible on utility bills in the heating period, select a foam with a density of 25 and 40mm thick;
- If you failed to buy special glue, you can use the usual glue cement, which is used for ceramics;
- Purchase the reinforcement grid with the size of the cells of 5mm;
- so that the foam fixed stronger on the wall, before applying the adhesive mass, the surface can be treated with a needle roller, which forms additional perforation;
- To increase the level of adhesion of foam plastic with reinforcement grid, before it is styling it is to climb the surface.
At the end, I would like to add that observing the above-described foam installation technology can be obtained warm housing without disturbing its microclimate. Thus, in your work, you will not allow any errors and reduce the amount of heat loss in your home.
As you can see, such insulation of the house does not take much time and your family budget will not suffer large financial waste if you will spend your own forces without attracting experts.
