UK Cladding Supplies helps you bring light into your building with GPR (Glass Reinforced Plastic) roof lights. The material is incredibly strong and durable, initially developed in the Second World War for planes, meeting safety standards and making it ideal for roofing. Unlike many other materials, GRP can be moulded into almost any shape. This means our roof lights are incredibly versatile and are available with a box profile roofing sheets or corrugated roofing sheets, matching the form of our box profile roof sheets and corrugated roof sheets. We also have roof lights in other shapes, such as Big 6 (Big Six), which was generally the profile used for roofing made from asbestos.
