Star PUF™ 15mm single skin panels are insulated roof panels with solar compatible and standard rib profiled steel exterior and soft interior liners such as Aluminium foil and LDPE polythene. The thermal insulation core can be customised in high-performance PUR and PIR. Star PUF™panel is the perfect replacement for normal roofing profile sheets providing excellent insulation in a cost-effective package. With a special clamp system, solar panels can be easily installed directly without piercing the sandwich panel surface. By doing this the structural integrity of the roofs is preserved and the lifespan of the structure is extended by eliminating the risk of corrosion and water leakage caused by screw holes in the structure.
