    To insulate the floors in a country house, you should choose a material with the following characteristics - moisture resistance, durability, ease of installation, low weight, low thermal conductivity. These parameters correspond to extruded foam polystyrene, expanded clay, polyurethane foam, mineral wool, glass wool, perlite, technical plug. The most popular are mineral wool and extruded foam polystyrene. The former has a low degree of shrinkage; good vapor permeability, which allows steam and condensate to escape unhindered; low thermal conductivity; high sound insulation. Expedited polystyrene foam has a low thermal conductivity, water and vapor tightness, resistance to mold and fungi, environmental friendliness and long service life. It is great for floor heating.

    First we will clarify the terminology. Under the commonly used term "polystyrene foam" »in the construction industry polystyrene is used, and it is mainly extruded. This is a very good material. It combines excellent heat-insulating ability and perfect immunity to moisture. Especially this material is good at heat and waterproofing of the basement space. It is also used as a thermal insulation for insulation works of enclosing structures (walls).
    The method described by you is often called "wet" »plaster warming. And the fact that it is "wet" imposes restrictions on the temperature regime of its use. Experts do not recommend using it when working in the vicinity of zero temperatures, and even more so in frost.
    Another aspect is that this material practically does not allow air to pass through. This is good for thermal insulation, and for ventilation - completely worthless. That is, the walls you a priori will not "breathe" *. This problem can not be dismissed, and you will have to solve it by creating a real system of supply and exhaust ventilation, because you do not want to live in a greenhouse.
    Still it should be said about the fire resistance of this material. She, admittedly, is not large, but after the plates of expanded polystyrene are drowned in mineral plaster, they will no longer be dangerous. In Western Europe, low-rise construction is almost completely converted to extruded polystyrene foam.

    Now the outer walls of brick houses are warmed with foam plates, followed by their plaster (on synthetic mesh) with adhesive mortar. What are the pros and cons of this method? Can I reproduce this technology myself?

  4. Yes, from foam it is possible to warm the house well and not only!
