Multi-foil and specifically is an easy to fit product that helps reduce heat transfer on all 3 fronts. By taking advantage of lowemissivity foil layers, radiation heat transfer is minimized. The loft & foam layers then help protect against conduction heat transfer. SuperFOIL also provides a barrier to the movement of air and controls air leakage. This control of air leakage is essential to the further improvement of energy efficiency and for insulating against convection heat transfer.
