Celotex CW4100 Cavity Wall Insulation Board 1200mm x 450mm (All Sizes)

The Celotex CW4100 insulation board is a high-performance, rigid polyisocyanurate (PIR) designed specifically for partial fill applications in masonry cavity walls. With a 100mm thickness, it fits seamlessly between cavity wall ties, making it suitable for both new builds, renovations, and extensions. Featuring a remarkable thermal conductivity of 0.022 W/mK and a low emissivity aluminium foil facing, it provides outstanding U-values, ensuring excellent thermal efficiency and long-term energy savings.

Sized to meet standard wall tie spacings, the CW4100 board eliminates the need for cutting, allowing for a quick and simple installation process. When properly installed, it helps meet national building regulations related to carbon emissions and energy efficiency targets.
