Thinking of adding more fiberglass? Don’t!

Every attic should have fiberglass or other mass insulation between the floor joists. But, once basic code requirements are met, additional mass insulation delivers diminishing returns. Radiaflect™ can give you the same R-11 insulation as an extra layer of fiberglass – plus 97% efficiency at stopping radiant heat transfer. It’s a far better investment than the same money spent on additional mass insulation.
