EXTERNAL WALL INSULATION
We stock a variety of rigid thermal insulation boards for installing externally as part of a render system. With the benefits of having a closed cell structure, Styrodur Extruded Polystyrene (XPS) is specifically designed for areas below the damp proof course where moisture could affect other insulation products thereby reducing their thermal performance and integrity of the system.

The innovative universal thermal insulation board. Styrodur 3000CS is an extruded polystyrene board with a constant thermal conductivity of 0.033W/mK across the whole range of thicknesses available (30-240mm). As well as the excellent insulation properties Styrodur 3000CS has a high compressive strength, low water absorption and is resistant to ageing and decay. Styrodur 3000CS is the all-round thermal insulation board with smooth surface and rebated on all four edges for flooring, roofing and wall applications.
