SuperFOIL SF40 will ::
SF40 is designed to super insulate roofs, lofts, ceilings and walls inside or out. Ideal for new timber-frame construction or eco retrofit projects, SF40 provides maximum insulation in the minimum space.
SuperFOIL is more resiliant to dust, drafts, pests and osmosys than mineral wool or extruded polystyrene, meaning it not only lasts longer, it maintains peak performance for longer too.
NOTE: For every roll of SF40 you install we suggest you allow 2-3 rolls of SF sticking tape, see related products opposite..
