SuperFOIL SF40 is the UK’s highest performing multi-layer foil insulation, use to reach levels 3, 4, 5 and 6 of the Code for Sustainable Homes. SF40 has radiant reflective properties, reflecting unwanted heat from solar gain in summer and enhancing insulation in winter. SF40 also has air barrier properties and can control air movement for further energy efficiencies. In situ energy assessment indicates that multilayer foils have benefits over traditional (non reflective) insulation. SuperFOIL SF40 maximises roof and wall insulation within an efficient amount of space. Request a sample pack!
