SolarPUF™ is an insulated roof panel with solar panel-compatible profiled steel exterior and ribbed interior liner. The thermal insulation core can be customised in high-performance PUR, PIR and Rockwool. 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.
