Isover RD35 – A Robust Details approved acoustic party wall insulation
Saint-Gobain Isover’s RD35 (E-WM-8, E-WM-14 and E-WM-15) enables house builders to cut costs and gain credits towards the Code for Sustainable Homes rating.
Made from up to 80 per cent recycled material, it is vastly more environmentally friendly than cement. The basic wall construction of E-WM-8 ensures one credit under the Code for Sustainable Homes, while increasing the design cavity with E-WM-14 to 100mm attracts three credits.
In addition, RD35 is proven with Aircrete blocks with the new Robust Detail E-WM-15 which also gives one credit under the Code for Sustainable Homes. Research by Isover has shown that the RD35 (E-WM-8) system can create cost savings of more than 20 per cent in materials and labour because the party wall does not have to be plastered on both sides and the contractor does not have to wait for the parge coats to dry.
