SF19 is constructed of 19 layers of interlaced materials. At 38mm thick it is the thickest multilayer foil product in the EU, this is because SF 19 SuperFoil Quilt has 3 layers of 80gram super loft quilting. As SF 19 SuperFoil Quiltdoes not require a large depth of wall or roof to install its excellent to use in new builds, extensions and conversions as it does not waste valuable and expensive floor space. Traditional Rockwool or Glassfibre needs to be around 300mm (1ft) thick to meet the new building regulations. Because few properties have 1ft thick rafters. Using XPS, Cellotex and Kingspan is an expensive solution and it places a heavy reliance on chemical foam. SF 19 SuperFoil Quilt being only 38mm thick is easier to install and seal. The best way of saving energy and reducing your carbon footprint is to conserve energy. We recommend you ’Super insulate’ with SF 19 SuperFoil Quilt by applying it over standard insulation
