Description

Ravatherm XPS X 300 SL is a flame-retardant 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 of A+ from BREEAM, and continues to enable the construction of energy-efficient buildings.

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

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