Poly carbonate roofing sheet ChatGPT Polycarbonate roofing sheets are a type of roofing material made from polycarbonate, a thermoplastic material that is lightweight, strong, and durable. Polycarbonate roofing sheets are commonly used in industrial, commercial, and residential construction projects, as they offer a number of advantages over traditional roofing materials. One of the main advantages of polycarbonate roofing sheets is their high impact resistance. They are virtually unbreakable and can withstand heavy impacts from hailstones, fallen branches, and other debris. They are also resistant to fire and UV radiation, making them a popular choice for outdoor applications.
