Foam insulation of walls and facades

With each heating season, the cost of services received is getting higher, and the temperature in dwellings is getting lower. Therefore, the issue of warming the facades of houses is acute. The choice of materials is varied. Styrofoam is one of the cheapest, but effective heaters.

Material properties

Due to its structure, the foam, and it consists of 2% expanded polystyrene and 98% air, has increased thermal insulation properties. The same structure makes it a good sound insulator and moisture resistant material. The cheapness of the material and the work performed with its use can significantly reduce the budget for the insulation of buildings.

Also, polystyrene is an environmentally friendly material, therefore it does not harm health, and can be used for internal insulation. Installation of the material is facilitated by its low weight and ease of handling. You can find more information about the benefits of polystyrene foam and more from the professionals at Warm House.

Foam application

In construction, this material is used to insulate a wide variety of surfaces. However, as you know, 50% of the heat is lost by the walls. Therefore, special attention is paid to them when warming. In multi-storey buildings, for residents of intermediate floors, the ceiling and floor are heated by neighbors, so it is enough to insulate the walls.

The walls in the room can be insulated with the following options:

  • outdoor
  • internal
  • From the name it can be seen that in the first case, the foam is fixed outside the building, and in the second case it is attached to the inner surface of the wall. The second method is mainly used when insulation cannot be carried out from the outside. Since when working from the inside, there is a danger of moisture forming between the foam and the wall. This can lead to mildew.

    Foam insulation of walls and facades

    When insulating walls, technologies are used that are used both for internal and external insulation:

  • Wet facade
  • Dry
  • wet technology

    In this case, the surface is cleaned of dirt and old coatings, and then washed with water. Depending on climatic conditions, the thickness of the insulation is selected.

    Foam sheets are glued to the wall using a special solution. For better fixation, dowels umbrellas are used. In this case, it is necessary to prevent the ingress of glue into the joints. After that, glue is applied to the resulting surface, which will fix the reinforced mesh. The mesh is primed, and then the plaster is applied.

    Works are carried out in dry warm weather.

    Dry technology

    Work can be carried out in any season. At the first stage, a frame is made that is attached to the wall. Styrofoam is inserted into it, umbrellas are used for fastening. The entire surface is covered with a membrane film, and then with a finishing material.
