What is the advantage of using a heavyweight radiant barrier foil?
Both the lightweight and the heavyweight radiant barrier foils have the same reflectivity quality. The difference is the lightweight products can tear easily. Generally foil comes in two weights: Lightweight which weights 13-16 lbs per 1000 square ft. or Heavyweight which weights 24-28 lbs per 1000 square ft. Atticfoil.com ONLY sells the heavyweight foil. The heavyweight foil is virtually tear-proof and will never rip or sag in your attic. See this video comparing the two products.
