Ravatherm XPS X 500 SL thermal insulation with its closed cell structure is a perfect solution for heavy-duty inverted roofs and floor structures.

Ravatherm XPS X 500 SL thermal insulation can be applied either above or below the reinforced concrete slab, even if laid down directly onto a compacted gravel bed. In this case the framework of the reinforced concrete floor structure can be assembled on top of the thermal insulation. The insulation of the building against soil moisture can also be prepared here. Using this method can save a layer of blind concrete, reducing costs.
