Norikool is designed to be installed on metallic or cement roof sheets , in place of polycarbonate or fibre sheets . There are two layers of specially defined shapes of polycarbonate sheets. The upper layer has a prismatic texture which enables Norikool to attract more sun light from all directions even during evening hours .
