GOLDFLEX PS3® insulation material consists of two inner layers of foam, laminated on both sides with a layer of LDPE foil and a layer of aluminum-metallized polyester foil. The foam is 11mm thick. This construction ensures the reflection of thermal radiation from the interior of the room and protects it from cold penetration. The foil also protects against moisture and acts as an acoustic barrier (up to 20 dB). The product can be used to insulate walls, ceilings, and doors. It is an ideal complement to polystyrene and mineral wool. It is ideal as insulation under screeds and underfloor heating, as well as for insulating rooms such as garages. The advantage of GOLDFLEX PS3® foam is its simple and easy installation.
