work compared to fiberglass?
BTUFOILâ„¢ will stop 96-97% of radiant heat energy (heat is radiated via infrared waves across an airspace). Radiant heat is often overlooked and misunderstood, as R-Values do not take it into account. Radiant heat transfer is responsible for up to 75% of total building heat gain or loss. Traditional Insulation products such as fiberglass, cellulose, and EPS foam board are effective in reducing CONVECTION and CONDUCTIVE heat transfer, but do little to prevent RADIANT heat transfer. Radiant heat energy can either be absorbed or reflected.
