Top layer - Is of Anti UV layer which is specially make to improve optical properties. Surface Layer- The material is ultra weather resistant; to block the ultra violet and reduce the coefficient of heat conductivity, ensure product durabipty and resistance to chemical corrosion.
Second layer - contains multi foam giving to the material light weight and improved sound and thermal insulating properties.
Third layer - It is specially inputs as fiber glass or steel net (can be customize as per customer) to make sheet more durable, give high strength to sheet, to improve bending problems compare to regular UPVC roofing sheets.
Underlying layer - for just a good material toughness special to ensure the strength at the same time, increase the rigidity and light illumination
4 layer UPVC roofing sheet has almost 10 times more higher mechanical strength compare to three layer UPVC roofing sheet. 4 layer UPVC roofing sheet has better resistance to bending problem than three layer UPVC roofing sheet. Hence this can give the better advantages comparing to other roofing sheets.
