FIELD: construction.
SUBSTANCE: invention relates to construction and can be used for insulation of cold floors, namely for floors of cold cellars. Heat-insulating flooring for cold floors of the building contains bars made of strong material with high heat-insulating properties, closed from above with heat-conducting surface sheet, End sections of said bars are closed by perforated sheets adjacent to heat-conducting surface sheet. Between bars there are heat-insulating strips forming air grooves between their upper surface and lower surface of said sheets, wherein the bars and the lower surface of the heat insulating strips of the heat-insulating flooring are laid on the upper surface of the base floor cold-covering so that the orientation of the air grooves and the bars were perpendicular, perforated and heat insulating sheets - parallel to the outer wall, and the edges of the perforated sheets and ends of the bars adjoined the outer and inner walls of the building.
EFFECT: invention improves reliability and efficiency of a heat-insulating flooring for cold floors of a building.
