SF40 is Superfoil‘s extra performance multifoil insulation. Extremely cost effective with a 68% increase in performance over our standard multifoil. SF40 beats any multifoil competitor products R value.

With a mission to build a better multi foil insulation SF40 combines the technical innovation of 37 layers and is configured for maximum efficiency, achieving higher values than previously thought possible within the industry. The enhanced thickness combined with radiant reflective properties and air barrier properties provide benefits over traditional (non reflective) open face insulation like glass fibre. SF40 includes CE certified vapor and water barrier outer layers.

SuperFOIL SF40 maximises roof and wall insulation with efficient use of space. SuperFOIL also has the strongest multi foil material aiding installation and reducing waste. LABC registered detail makes Building Regulations simple.
