Walltite CV 100, closed cell polyurethane foam, has now received BBA certification for insulation and stabilisation of masonry cavity walls. The certification recognises both the improved thermal insulation and structural stability that can be achieved by using this type of system.<br> <br> BASF's Walltite CV 100 is designed to be injected into cavity wall structures and is typically used in both new build and refurbishment projects.<br> <br> Product testing proves the efficacy of Walltite CV 100 for cavities as narrow as 40mm, where the U-value of the finished wall structure will be between 0.39 and 0.56 depending on the materials used in the existing wall, BASF says.<br> <br> The certification also recognises the use of Walltite CV 100 as a cavity wall stabilisation system for use in masonry cavity walls in which conventional wall ties have corroded. The product stabilises the wall by adhering to the inner surfaces of the cavity and providing a continuous structural connection between the two leaves.<br> <br> <a href="http://www.walltite.basf.co.uk">www.walltite.basf.co.uk</a>
