Ravatherm XPS X 300 SB 150mm Extruded Polystyrene

Ravatherm XPS X 300 SB is a premium extruded polystyrene thermal insulation board featuring a butt-edge profile, engineered for high-performance construction applications. This board achieves outstanding thermal efficiency with a declared 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.

Manufactured with environmental responsibility at its core, 150mm Ravatherm 300 SB boasts a Global Warming Potential (GWP) of less than 5, positioning it as an eco-conscious insulation solution.

With exceptionally low water absorption properties, verified to BS EN 12087:2013 standards, this extruded polystyrene board performs excellently for below DPC cavity wall insulation and other moisture-sensitive applications.

Available in thicknesses ranging from 30mm to 200mm, these 150mm Ravatherm XPS 300 SB boards provide adaptability across diverse UK residential and commercial construction schemes.
