Product Description
The AT-3 Attic Tent is an attic access insulator designed to create an air transfer barrier between the attic and the conditioned living space below. With a 22" wide x 54" long footprint and a taller 13" height clearance, this model is a good fit when the attic access needs more vertical room than the lower-profile AT-1 or AT-2 sizes. It includes a 2" mounting flange and is made for fold-down attic stairs, scuttle holes, and knee wall doors.
What sets The Original Attic Tent apart is its verified thermal performance. The brand states that the Attic Tent was tested and R-value rated by Oak Ridge National Laboratory at R-6.6, with a reported 76% reduction in energy loss/transfer. That gives homeowners, contractors, weatherization crews, and energy-efficiency professionals a stronger selling point than generic attic stair covers that do not provide the same recognized R-value testing claim.
Made from nylon fabric and polyurethane foam with flame-retardant treatment, the AT-3 helps reduce drafts, air leakage, humidity transfer, and energy loss through attic access openings. It is a practical upgrade for improving comfort and supporting home energy-efficiency projects, especially in homes where the attic stairs or access hatch create a noticeable weak point in the building envelope.
