60mm x 1200mm x 450mm Celotex PIR Cavity Wall Insulation Board CW4000

Celotex CW4000 PIR cavity wall insulation board measures 1.2m in length, 45cm in width, and has a thickness of 6cm, providing a total coverage area of 0.54 mâ. Celotex CW4000 is an easy-to-install polyisocyanurate (PIR) insulation board with excellent thermal performance, featuring a low-emissivity foil facing. Excellent thermal performance with a thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value. Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value. The boards are light and rigid assisting with ease of transportation, handling and fitting. They are sized to fit standard wall tie spacing for ease of installation. Has been assessed by the BBA as fit for use in defined partial fill cavity wall applications if installed, used and maintained as set out in the certificate.
