Intended for partial fill insulation for masonry cavity walls, this Celotex CW4100 insulation board is a high-performance rigid polyisocyanurate (PIR). It included a 100mm thickness and is sized to fit between cavity wall ties across both new and existing builds as well as extensions. It has excellent thermal conductivity value of 0.022 W/mK and includes a low emissive aluminium foil facing to aid in obtaining impressive U-values, making this sturdy PIR board one of the best-performing options on the market while providing reliable long-term savings.
CW4100 has been sized specifically to fit the standard wall tie spacing requirements. This means that you don't have to cut your board, allowing for installation that is easy and quick. As long as it's installed correctly, it can help meet carbon dioxide emissions and energy use targets set by the national building regulations.
Additionally, CW4100 comes with a BBA (British Board of Agrément) certificate so that you can confirm that it's designed to the highest industry standards. It even has BRE (Building Research Establishment) Green Guide Rating of A, so that you can improve your environmental performance substantially.
