Many people today still think that polystyrene is a combustible material.
But modern technologies for the production of polystyrene foam have made it possible to ensure that this type of material does not support burning at all.
Therefore, today, polystyrene - is great for warming a private house. In its favor, there is also environmental friendliness and a very low price.
Carrying out the insulation of the frame house foam can significantly save without compromising the quality of insulation works.
Such material not only reliably stores heat in the house, but also allows the house to breathe.
Although the foam itself does not pass, but using a special system of joints and air space, you can achieve excellent ventilation at home.
In addition, polystyrene creates excellent sound insulation and prevents water from penetrating into the house.
If you are going to conduct high-quality insulation of the frame house foam, then when buying such a thermal insulation material, you need to look for the material to be free from damage.
High-quality material will allow safe and reliable insulation of the frame house. In this case, you do not have to spend a lot of money on this.
It is best to use polystyrene foam for warming a frame house on a ventilated facade.
When carrying out insulation work inside the house will have to use a vapor barrier film.

It reliably protects the skin from condensation accumulation. Thus, the house will be reliably protected from fungi and bacteria.

Pros and cons of
Polystyrene is not only cheap. It holds well any shape and can be easily processed.
Due to the quality of this insulation material is widely used in individual and industrial construction.
The thermal insulation material under consideration allows to significantly reduce the price of the construction process. It is used not only to warm the walls of frame houses.
Polyfoam can also be used to insulate floors and concrete floors.
The pluses of polystyrene can also be attributed to its ability to keep shape. Therefore, it is excellent for thermal insulation of vertical surfaces in the house.
Polyfoam will not crawl, like mineral wool or backfill.
When using this material, when carrying out thermal insulation work, it is not necessary to conduct hydro and steam insulation work, because the foam does not allow moisture and steam to pass through.
The pros and cons of house insulation with polystyrene are often assessed ambiguously. Some believe that the foam is too tight and does not allow the house to breathe.

When warming the house is installed from 2 to 3 layers of polystyrene, which overlap the joints of the previous layers. In addition, the joints between them are filled with foam.
This is what causes the censure of skeptics who believe that in this case the house stops breathing at all.
But such insulating material is no worse than mineral wool.
Thermal insulation layers made of foam plastic have the same thickness as in mineral wool, in which waterproofing films are also supposed to be used.
The house, insulated with foam, continues to breathe through the holes provided by the design.
Therefore, such material does not harm it and does not disrupt air exchange in the construction of the house.
Heat insulation of walls
Polyfoam is a universal thermal insulation material that allows to conduct insulation of the walls of the frame house with foam plastic both outside and inside the house.
If the insulation is to be insulated from the inside, then the thickness of the sheets should not be more than 2.5 cm.
This will not reduce the overall area of the room due to too thick layer of insulation.
To correctly calculate the amount of material required, you need to multiply the length and height of the walls.
The technology of installing a foam insulation layer inside the house includes:
- The preparatory stage in which old plaster and putty are removed from the walls. The wall must be completely free from dust and dirt;
- After that, the peeled wall is treated with a primer, which includes special antifungal additives that will reliably protect the house from mold and fungi;
- Installation of foam plates starts only after the primer has dried. For reliable fixing of foam plates in an upright position, the adhesive composition is applied, which is applied either to the primed surface or to the surface of foam plates. Then the foam is pressed against the wall and held for several minutes. So the entire surface is glued. After the glue dries, an additional fixation of the foam is carried out with dowels having wide hats that allow them to stick to the surface of the foam;
- The next stage is the reinforcement of the walls. Foam is applied with an adhesive composition with a spatula, and then the reinforcing mesh is heated in it;
- When all this is dry, the walls can be leveled with plaster and presed by re-priming the surface, then finish finishing the finish.
Thermal insulation of the ceiling and floor
Foam can also be used to insulate the ceiling in the same way. For quality heat insulation of a private house, this technological process is of the same importance.
The insulation of the ceiling can also be carried out both from inside the house and from the attic side. Specialists recommend conducting an external installation of foam plastic.

Installation of foam plastic for thermal insulation includes:
- Primary installation of thermal insulation material. Sliced parchment is laid in an overlap between the ceiling beams. The strips should overlap each other not less than 5 cm. After that, the parchment is fixed with racks, which are nailed to the ends of the beams;
- The foam plates are then adjusted to fit and fill the space between the ceiling beams. All cracks and gaps are then fixed with a mounting foam;
- Then lay the waterproofing material with glassine, on top of which is laid a layer of mineral wool;
- After that, the finishing is finished, including the installation of flooring.
The technology of floor insulation with polystyrene passes in several stages.
First stage
First, the preparatory works are carried out, where the floor is cleaned of the old coating.dust debris.
Floor floor defects are eliminated with putty and foam.
The second stage of
The second stage is the laying of the waterproofing layer. It is superimposed on the sex base in an overlap of 10 cm.
Docked areas should be glued with adhesive tape to ensure that the flooring is sealed.
The third stage of
The third stage is the laying of the thermal insulation material on the waterproofing basis. Polyfoam can be stacked in several ways.
The most common method of laying is when the foam sheets are laid parallel to the walls.
Also sheets of foam can be placed diagonally. In this case, they should lie at an angle of 45 degrees to the surface of the walls.

You can also stack the foam insulation in the decay. In this case, the angles of the different plates may not coincide with each other.
For stowage in the decoupling, it is necessary to take foam plastic with a thickness of 20 mm and a density of 35 kg / m.
Fourth stage
In the fourth stage of thermal insulation works, waterproofing measures are carried out. As a material, a polyethylene film can be used.
In case if ceramic floor tile, laminate or carpet is used as a floor covering, the PVC membrane is best suited for waterproofing the floor.
It is then installed with chipboard plates, which are a rough floor covering.
Fifth stage
In the fifth stage, a cement-sand screed is produced. The thicker it is, the more time it will take to dry it. In general, it takes no more than one month.
On the reinforced screed is installed a facial floor covering.
