DGSL Attic Stairway Insulation Cover – Premium Attic Door Tent 25x54x11

All-year attic door insulation that seals, reflects heat, and minimizes drafts

DGSL’s Attic Stairway Insulation Cover is a premium, tent-style enclosure designed to fit openings up to 25" x 54" x 11". It creates a snug barrier at the attic door, helping to keep dust and pollutants from drifting into living spaces while reducing drafts you may notice when moving between floors. The result is a more comfortable first impression when you enter and exit the attic, with less air exchange around the door itself.

Premium materials for lasting performance

The core is a premium foil bubble insulation sandwiched between two aluminum layers. This construction actively reflects radiant heat, offering a high level of thermal control. The assembly also helps guard against moisture and humidity, contributing to a drier, steadier indoor environment. An R-Value of 14.5 is noted for the product, indicating solid insulating performance for typical attic conditions.

Easy installation that works with real homes

The setup is designed for a straightforward, homeowner-friendly process. A zipper access panel provides convenient entry, and the cover can be stapled to the door frame for a secure fit. The kit includes the tools and hardware you need to complete the install with minimal fuss.

Designed for practical, real-world use

With a fit up to 25" x 54" x 11", this attic insulation cover supports year-round comfort in homes with attics used for storage, access, or occasional maintenance. In hot summers, it helps curb direct heat flow; in cold winters, it helps slow cold drafts from entering living spaces.
