The Attic Stairway Insulator is designed to reduce energy loss around attic stair access points. It is made of durable fiberglass insulation and reflective foil, and closes insulation gaps. Thermal imaging shows the insulator reduces surface temperature differences by insulating the attic stair panel similarly to the interior. The insulator is easy to install by simply unfolding and placing over the opening, and can earn homeowners energy cost savings year-round.
