A layer of polystyrene (EPS) board with patented holes is laid on the traditional concrete roof, and the concrete in the holes thus forms a structural support, which can increase the strength of the roof laminate and the overall structure. It has the functions of heat insulation and sound insulation. The sound insulation according to CNS8465-1 test shows that it can reduce 17dB air penetration sound. The thermal insulation effect has been tested, and its heat transmission rate U value is 0.606, which is far lower than the standard value (0.72) of the Ministry of the Interior for green building materials.more
