The RAVATHERM™ XPS 500 SL thermal insulation boards, made of closed-cell polystyrene foam, are the perfect solution for the thermal insulation of highly stressed inverted roofs, floor structures and load-bearing reinforced concrete slabs. Even in the long term, they offer a high load capacity, only low compression and excellent thermal insulation properties even in humid environments.
