PU (polyurethane hard) foam board is a new type of synthetic material with thermal insulation and waterproof functions. Its thermal conductivity is low, only 0.017~0.022W/(m*Κ), which is the lowest thermal conductivity of all foam insulation materials. Its thermal insulation effect far exceeds that of XPS (extruded polystyrene), PET (Polyethylene terephthalate), PVC (Polyvinyl chloride), EPS (Expanded Polystyrene) , rock wool and other types of foam materials.
