Celotex 50mm Cavity Wall Insulation Board 1200mm x 450mm - Pack of 11 - CW4050

The Celotex 50mm Cavity Wall Insulation Board (1200mm x 450mm - Pack of 11 - CW4050) is a lightweight and rigid PIR board designed specifically for partial fill cavity wall applications. Manufactured from polyisocyanurate (PIR) with a low emissivity foil facing, it offers reliable thermal performance while keeping insulation depths to a minimum. With a thermal conductivity of 0.022 W/mK and an R value of 2.25 m2.K/W, these boards help improve energy efficiency and achieve building regulation U-values more easily. Supplied in packs of 11 for convenience, they are simple to handle, transport and install on site. Please note: this product is not suitable for use in the external walls of buildings over 11 metres in height.
