The benefit of using clear Polycarbonate Skylight Roofing is primarily in the fact that is both lightweight and durable. Because conservatories and other rooms like it primarily have lightweight glass walls, they often cannot support a heavy roof without the potential for leaks or cracks. Polycarbonate roof panels don’t leak or crack and are usually less expensive than glass panels as well. The other type of polycarbonate awning used more often on commercial buildings, but gaining acceptance on more residential buildings is foam-backed polycarbonate roofing. This type of roof panel is corrugated to resemble a metal roof but is much lighter weight. The foam backing on the panels helps to insulate the building, while the protective coating on the panels deflects UV light. The result is a roof that helps keep your home more even in temperature year-round, resisting heat transfer in both directions.
