The vast majority of domestic buildings for civilian purposes of small and medium floors (up to 5 floors inclusive) have pitched roofs with a cold ventilated attic space. With all the obvious advantages of this design solution, the problem of the formation of ice and icicles on the roof due to heat leaks in the attic space continues to be very acute. Obviously, the most effective solution to this problem is to increase the level of thermal protection of the attic floor. To warm attic floors, it is recommended to use lightweight expanded clay gravel with a bulk density of 200–250 kg/m3, which, unlike mineral wool boards of increased stiffness, is non-combustible, does not lose operational properties for a long time (50 years or more ) and does not require a device on top of the insulating layer of a protective screed made of cement-sand mortar. The insulation of the attic floor in the form of a backfill made of lightweight expanded clay gravel 350-400 mm thick fully complies with modern heat-technical standards for central Russia and is much cheaper than the traditional version of insulation with mineral wool slabs and cement-sand screed.
