Ravatherm XPS X 300 SB 60mm Extruded Polystyrene

Ravatherm XPS X 300 SB is a premium extruded polystyrene thermal insulation board featuring a butt-edge profile, engineered for rigorous construction demands. This board achieves outstanding thermal performance with a thermal conductivity of 0.030 W/mK for thicknesses up to 120mm, and 0.031 W/mK above this threshold, supporting compliance with UK Building Regulations and energy efficiency standards.

Produced with environmental responsibility, 60mm Ravatherm 300 SB carries a Global Warming Potential (GWP) below 5, positioning it as a sustainable insulation solution.

Its exceptionally low water absorption rate, validated to BS EN 12087:2013, makes this extruded polystyrene board particularly suited for below DPC cavity wall insulation and moisture-sensitive applications.

Available in thicknesses spanning 30mm to 200mm, Ravatherm XPS 300 SB boards provide adaptability across diverse UK residential and commercial construction schemes.
