One of the major advantages of polycarbonate roof sheets is that the sheets are translucent, allowing light to penetrate. Not only does this mean they provide welcome daylight in sheds and similar, they also make an excellent roofing for greenhouses and other outdoor structures. Double walled polycarbonate sheets for roof projects provide welcome additional insulation against both heat and cold. We offer polycarbonate roof sheets cut to size, providing an easy option for roofs which are an awkward shape. Cut-to-size sheets also minimise waste, enabling you to obtain best value on all the items in our polycarbonate roof sheets range.
