Polycarbonate structured sheet is a tough, lightweight, insulated glazing sheet with all the toughness of polycarbonate material. It is energy efficient with U-values comparable to insulating glass. The hollow-core structure uses 80% less material than a solid glazing sheet, weighs 1/6 as much as glass and 1/3 as much as acrylic. It is widely used in skylights and roof windows, atria, sports halls, industrial plants, greenhouses, solar collectors, window replacements and more.
