The installation of a warm film floor is carried out according to the same principle as the water heating floor. To prevent heat leakage in the concrete screed, a thermo -insulating substrate is installed under the film. As a thermal insulating substrate, you can use the fiberboard plate, which is isolated from the filler floor with aluminum foil or other heat -resistant coating, which will create the isolation of thermo -elements from the substrate. The film floor is laid in stripes, and is covered in front of the floor covering the floor with a heat -led thermal shit. For floor covering the warm floor, it is better to use flexible linoleums or carpet. Wooden coating and coating with laminate slabs is ineffective to cover the warm film floor. The film floor is connected to the common room power supply through the thermostat.
