Celotex Thermaclass cavity wall 21 is the new Celotex ‘Full Fill’ cavity wall insulation solution. This board comes in 90mm , 115mm and 140mm thick and has mechanically engineered tongue and groove edges. Importantly this feature allows the insulation boards to interlock and aids with the resistance of moisture across the cavity construction. With it being a full fill cavity insulation this helps achieve higher ‘u’ values in the cavity than any partial fill celotex board. This thermaclass high specification cavity wall insulation board can help reduce the requirement of insulation fitted to the interior of the project.
