Polistyle ceiling foam coatings are convenient to use. They are stiff, moisture resistant, not subject to decay, do not attract dust and do not attract statistical discharges. Installing them is not particularly difficult. Polistyle ceiling foams have different colors and textures. Their disadvantages are low strength and alloy. Therefore, such coatings must be placed at a distance of 25-30 centimeters from incandescent lamps.
