200mm Ravatherm XPS X 300 SB Extruded Polystyrene Board

200mm Ravatherm XPS X 300 SB is a high-performance XPS thermal insulation board with a butt-edge profile, designed for demanding construction applications. It delivers excellent thermal efficiency, with a declared thermal conductivity of 0.030 W/mK for thicknesses up to 120mm, and 0.031 W/mK for thicknesses above this, helping to meet UK Building Regulations and energy-efficiency requirements.

Manufactured with sustainability in mind, 200mm Ravatherm 300 SB has a Global Warming Potential (GWP) of less than 5, making it a more environmentally responsible insulation choice.

Thanks to its very low water absorption , tested in accordance with BS EN 12087:2013, this extruded polystyrene insulation is ideal for below DPC cavity wall insulation, as well as other moisture-resistant applications.

200mm Ravatherm XPS 300 SB insulation boards are available in a wide range of thicknesses, from 30mm to 200mm, offering flexibility for a variety of UK residential and commercial construction projects.
