Stay warm and boost energy efficiency with Celotex Thermaclass Cavity Wall 21 Tongue and Groove Insulation Board 115 x 1190 x 450mm. This 115mm cavity wall insulation board is made for full fill applications and deeper cavity walls, using rigid PIR material and a clever tongue and groove edge for a snug fit that minimises gaps and heat loss. Celotex Thermaclass combines lightweight handling with a low emissivity foil facing, so you’ll find it easy to install in both housing and commercial projects. With impressive thermal conductivity, you can achieve low U-values and reduce overall wall thickness, all while making installation faster and more efficient. Pack of 15.
