The floor screed implies the thermal insulation layer

The issue of insulation of apartments of the first floors is associated with heat loss through the floor if there is a cold basement under them. Therefore, insulation of the screed of the parances of a significant degree reduces the dispersion of heat into the environment. On the other hand, insulation under the screed is relevant when designing a “warm floor” system, when all heated air should be directed to useful work: heating the floor and the whole house. Thermal insulation of the intermediate layer between the base and the finished flooring of the floor should be carried out on an even base. First, laying the insulating layer, on it — polyethylene. Tight installation of the reinforcing mesh is carried out. The whole «pie» is filled with a screed. Thermal insulation in the form of expanded clay, foam, mineral wool, granular foam for screed is characterized by a high degree of sound permeability.
