SuperFOIL SF19BB is an all-in-one multifoil insulation, breather membrane and radiant membrane. It consists of 9 layers of reflective foil and thermo foam separation sheets which offer a vapour and air barrier that works to efficiently reduce draughts and other air leakage.   

The radiant barrier foil in SuperFOIL SF19BB allows the material to protect against heat loss through radiation, a feature that is absent in other non-foil insulation methods. By combining breathability and insulation, the installation time is significantly reduced and there is no need for extra battens. Engineered with state-of-the-art sonic construction techniques, advanced lamination developments, and nano-technology, SuperFOIL SF19BB sets a new standard in performance and efficiency.
