Plastic tile roofing sheet international advanced co-extrusion technology and applies the first class produce this kind of new roof tile. The surface film is PMMA material, which is a kind of super high anti weathering engineering resin materials. Surface layer the material is ultra-weather resin, to block the solar ultra violet and reduce the coefficient of heat conductivity, ensure product durability and resistance to chemical corrosion. Surface intermediate layer contains Multi foam giving to the material light weight and improved sound and thermal insulating properties. Under lying layer for just a good material toughness special to ensure the strength at the same time, increase the rigidity and light illumination.
