Offering numerous advantages to housebuilders and installers alike, Knauf Insulation says it is highlighting the benefits of its Supafil blown-in glass mineral wool insulation as a solution for both external and party masonry cavity walls.<br> <br> Since the changes to Part L1A of the Building Regulations in 2010, much greater emphasis has been placed on reducing the heat loss associated with party wall cavities. Mineral wool is the only insulant proven to work as a full-fill solution for both external and party masonry cavity walls, Knauf claims, and offers significant onsite savings when installed in all walls of this type throughout a project.<br> <br> Knauf Insulation's Supafil blown-in glass mineral wool offers peace of mind that the system will be installed correctly and efficiently, Knauf says. For housebuilders, choosing to use Supafil in both party and external masonry cavity walls means the same approved installer will be working across the entire build, saving on labour, machinery and on-site costs – and with only one point of contact and one contract to sign, the procurement process is much more straightforward.<br> <br> www.knaufinsulation.co.uk or enter E0398 on the reader enquiry card
