Ravatherm XPS X 700 SL closed cell polystyrene foam thermal insulation. Its thermal insulation capability, high compressive strength and resistance to moisture ensure that it can be safely used in locations where good thermal insulation capability is only one of many complex requirements. It is suitable for loadbearing industrial floors, base slabs or high-load rooftop car parks.
