FIELD: construction.
SUBSTANCE: panel consists of porous non-expanded fibre-reinforced thermoplastic internal layer, including thermoplastic material and from 20 to 80 wt % of fibres. It is followed by adhesive layer of thermoplastic material. Further airtight barrier layer is arranged of thermoplastic material, having melt temperature exceeding melt temperature of thermoplastic material of internal layer. Textile layer made of nonwoven and woven textile materials is joined to barrier layer and produces external surface of panel. Decorative layer is attached to opposite surface of internal layer.
EFFECT: multilayer panel has sound-absorbing properties.
