Celotex GA4070 is a high-performance multi-purpose insulation board suitable for a large array of applications, such as flat roofs, pitched roofs, solid floors and masonry walls as well as timber framed and steel framed systems. It comes with an innovative low emissivity foil facing. Manufactured from rigid polyisocyanurate (PIR), it's easy to cut and shape for greater convenience. Thanks to an impressive thermal conductivity of 0.022 W/m.K, this endlessly versatile insulation board has excellent thermal performance. As a result, it's able to meet the target U-value even though it's thinner than most similar products on the market.

But that's not all! The low emissivity foil facing improves thermal performance in sealed cavity air spaces and helps raise the potential U-value. The GA4070 is designed to the highest industry standards and approved by the BBA (British Board of Agrement) as fit for use in defined roof, wall and floor applications when installed, used and maintained as set out in the certificate. Last but not least, this insulation board has a BRE (Building Research Establishment) Green Guide Rating of A, which will help your environmental performance while providing reliable long-term energy savings for your home.
