Electric warm floors in design are film and cable. Cable systems are installed in the inside of the floor screed. But this has no effect on the thickness of the main layer. The film floors, on the contrary, can already be installed on top of the screed, but on the pre -laid insulating layer of polyethylene. It is desirable that its surface is foil. High -quality and correctly installed electric warm floors provide a full heating of those rooms that are not connected to the main sources of heating: verandas, balconies, loggias, various open areas, attic.
