PU Foam metal roof are designed to provide higher level of thermal insulation and sound proofing. PU foam or Polyrethane foam are sandwiched between the metal roofing sheet and PVC lamination. The PVC lamination is to provide fire resistance and added layer of defense against wear and tear. Moreover, the interior PVC lamination enhances the appearance of the PU Foam roofing with choice of glossy and/or textured surface.The main purpose of PU Foam in metal roofing is to resist heat from entering (summer) or leaving the building (winter). This feature allows energy saving by lowering energy consumption on air conditioning or heating.Likewise, PU Metal Roofing significantly reduces noise particularly when it rains. Knocking noise due to direct rain impact on metal roof can be absorbed by PU Foam. In fact PU Foam is the same material used to provide sound proofing for cars and factory machines. It is a highly effective material for sound proofing.
