FIELD: construction.
SUBSTANCE: invention relates to structural finishing sound-proof materials and deals with a method of manufacture of panel three-layer structures. It includes the following stages: providing a base panel made of a wood-based material, arrangement of an acoustical layer above the base panel, arrangement of a coating over the base panel and pressing of a three-layer structure, preferably in the press. The used acoustical layer is elastic plastic. According to the first alternative version of the invention, the named elastic plastic is polyfoam with close pores treated by a corona discharge. According to the second alternative version of the invention, the named elastic plastic is a self-adhesive plastic which connects the base panel to the coating panel, it is elastic in a solidified state, and has the minimum thickness of 03 mm.
EFFECT: invention provides the creation of the panel three-layer structure containing the durable sound-proof layer.
