Ravatherm XPS X 300 SL is a flame retarded extruded polystyrene with exceptional lambda insulation performance and a Global Warming Potential (GWP) of less than five. It has attained a coveted Green Guide Rating A+ by BREEAM and continues to enable the construction of energy-efficient buildings.

Ravatherm XPS X 300 SL is a high-performance, multi-purpose polystyrene for the thermal insulation and frost protection of inverted flat roofs, and green and blue roofs.

It is manufactured by an extrusion process which results in a homogeneous, closed-cell material structure and smooth surface skin (extrusion skin) which has many favourable material characteristics.
