This Celotex CW4060 insulation board has been designed specifically for partial fill insulation for masonry cavity walls. This high-performance rigid polyisocyanurate (PIR) is available in 60mm thickness and has been sized to fit between cavity wall ties and is suitable for use in both new and existing builds as well as extensions. It boasts a low thermal conductivity value of 0.022 W/m.K and features a low emissive aluminium foil facing that helps it achieve impressive U-values. So, it should come as not surprise that this sturdy PIR board is among the best-performing insulation materials on the market and offers reliable long-term savings.

Since the Celotex CW4060 is sized specifically to fit the standard wall tie spacing requirements, no cutting is required, and the board is quick and easy to install. When installed correctly, it can help meet carbon dioxide emissions and energy use targets set by the national building regulations. What's more, CW4060 has a BBA (British Board of Agrement) certificate, so you know it's designed to the highest standards. It also has BRE (Building Research Establishment) Green Guide Rating of A, which will help boost your environmental performance.
