FIELD: construction. ^ SUBSTANCE: may be used for heat protection of fencing structures. The invention purpose is to enhance sound-insulating capacity of heat-insulating materials based on foil-coated foamed polyethylene, production of materials with preset sound- and heat-insulating properties. The objective is attained due to the following: the heat-insulating material contains layers of foil-coated foamed polyethylene and an intermediate plastic layer, its external layers are made of foamed polyethylene bands coated with foil from one or two sides, a bulk layer of crushed particle granules is located between the foil-coated foamed polyethylene bands; the particles are foil-coated polyethylene pieces glued together, forming a combination of closed and open cells. ^ EFFECT: disposal of waste from production of foil-coated foamed polyethylene and similar materials; possibility to obtain heat-insulating materials with given sound-insulating properties. ^ 3 dwg |
