Knauf Insulation has launched Supafil 34, a glass mineral wool insulation designed to be blown into existing cavity walls

The product meets the Lambda 90/90 requirement of European standard BS EN 14064:1:2010 and has a thermal conductivity value of 0.034W/mK. Manufactured using recycled glass bottles, Supafil 34 also has a BRE Green Guide generic rating of A+. The company claims that Supafil 34 can provide a full solution for both external and party walls, meaning all cavity walls can be insulated at the same time, saving on labour, machinery and onsite costs.
