Celotex XR4000 PIR Insulation Board 1200 x 2400mm

Celotex XR4110 is a high performance rigid polyisocyanurate (PIR) insulation board that is extremely lightweight making it very easy to handle, transport and extremely easy to install due to its rigid nature. Being a high performance PIR insulation board, it offers excellent thermal performance with a thermal conductivity of 0.022 W/m.K, it is available in a range of thicknesses from 110mm to 200mm. Its high thermal efficiency allows a reduction in the thickness of the insulation required to help achieve the target U-value. As an added benefit it also features a low emissivity foil facing for improved thermal performance in sealed cavity air spaces, helping to improve the achievable U-value. Manufactured to be trimmed to specification, the Celotex XR4110 insulation board is perfect for use between rafters and joists where they can be fitted to provide a highly insulating layer of insulation without being super thick and losing valuable space. This range of products has been assessed by the BBA and is fit for use in pitched and flat roofs, external walls and ground floor applications. Celotex XR4110 achieves a BRE Green Guide Rating of A, which can assist in demonstrating environmental performance in your BREEAM assessments. Manufactured from rigid polyisocyanurate (PIR) using a blowing agent that has zero ozone depletion potential (zero ODP) and low global warming potential (GWP).
