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 . The lower layer of polycarbonate , which is placed 4 inches below the upper sheet , acts like a diffuser. The gap between these two sheets traps the heat & does not allow it to flow to the shop floor.
