In 2015, Recticel’s premium Eurowall+ cavity wall insulation was launched and won British Board of Agrement (BBA) approval.
A U-value of 0.18 W/m²K can be achieved in new-build constructions using 90 mm Eurowall+ within a 100 mm cavity. This meets the requirements of Part L1A England 2013 and Part L1A Wales 2014, meaning that existing designs can be retained to avoid reducing room sizes which could make the properties less attractive to prospective buyers.
Existing designs can also be retained without increasing building footprints which has the potential to reduce the number of properties on a site, making development less attractive for house builders.
Also manufactured at 75 mm for 85 mm cavities, 115 mm for 125 mm cavities and 140 mm for 150 mm cavities, Eurowall+ features a unique tongue and groove joint on all four sides to ensure the boards lock tightly together to minimise heat loss through thermal bridging. As well as improved air tightness, this also offers additional protection against wind-driven rain.
