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.
Boards are light and rigid assisting with ease of transportation, handling and fitting.
Assessed by the BBA as fit for use in defined roof, wall and floor applications if installed, used and maintained as set out in the certificate. Please read the certification at insulation-UK.com/

Warm Roof construction is a particularly effective way of insulating complex
roofs. Insulating above - or above and between - the roof timbers ensures
that the structure is kept at or near the internal environmental conditions,
reducing thermal stress and condensation risk.
Celotex CW4000 PIR cavity wall insulation board measures 2.4m in length, 1.2m in width, and has a thickness of 10cm, providing a total coverage area of 2.88 m2. Celotex CW4000 is an easy-to-install polyisocyanurate (PIR) insulation board with excellent thermal performance, featuring a low-emissivity foil facing.
