Celotex XR4110 is a versatile multi-purpose insulation board suitable for all sorts of applications including pitched roofs, flat roofs, solid floors and masonry walls and steel framed and timber framed systems. It's made of polyisocyanurate (PIR), and it's easy to handle, cut and shape, making it convenient solution. This high-performance insulation board delivers outstanding thermal performance, thanks to an impressive thermal conductivity of 0.022 W/m.K. Keeping that in mind, you won't be surprised to learn that it easily meets the required U-value even though it's thinner than most similar products on the market.

But that's not all! The innovative low emissivity foil facing improves thermal performance in sealed cavity air spaces and boosts the potential U-value. As you'd expect from Celotex, the XR110 has been designed to the highest industry standards, with a BBA (British Board of Agrement) seal of approval as fit for use in defined roof, wall and floor applications when installed, used and maintained according to the guidelines in the certificate. What's more, the XR4110 has a BRE (Building Research Establishment) Green Guide Rating of A, which will help improve your environmental performance. All in all, this PIR insulation board will provide substantial long-term energy savings for your home.
