Its layered aluminum and bubble insulation is intended for year-round use, while the zipper lets you open the cover when you need to reach the attic. It fits openings up to 25 x 54 x 11 inches and attaches to the door frame with staples. That makes it a different approach from treating only the edges of an attic hatch: the cover encloses the stair opening itself. ## Who it’s for This cover is for homeowners looking to insulate an attic stairway and help keep dust, pollutants, and excess heat from passing through the opening. You’ll appreciate it if you want a barrier that can be opened for attic access rather than a permanently sealed solution. The stated fit limit is important: measure the opening and compare it with the maximum dimensions before choosing it. It may also suit people dealing with noticeable temperature changes near an attic access point. Buyers describe improvements in draft and temperature control, though those reports reflect individual experiences and don’t establish a specific result for every home. It’s not for you if your opening exceeds the listed fit dimensions or you need a cover that installs without stapling to the frame. ## Technical details - Type: Attic stair insulation cover - Material: Aluminum with bubble insulation - Fits openings up to: 25 x 54 x 11 inches - Product dimensions: 54 inches long x 25 inches wide - Coverage: 9.38 square feet - Access: Zipper - Installation: Staple to the attic door frame - Model: Attic Insulation Cover ## Where it shines The zippered access is useful when the attic still needs to be reached, you can open the cover rather than remove the barrier each time. The aluminum layers and bubble liner are designed to help limit radiant heat transfer, while the cover is also intended to reduce drafts and keep dust or pollutants out of the living space. The product description cites 97% radiant heat reflection, but that figure alone doesn’t predict how much a particular home’s temperature or energy use will change. Buyer feedback commonly describes installation as straightforward and reports better control of heat and cold drafts near the stairs. Experiences with the zipper are less consistent: some find it works well, while others report that it failed after a period of use. That’s a useful trade-off to consider if the attic is accessed frequently. For a practical fit check, confirm the opening dimensions and plan for fastening the cover to the frame before installation. ## Questions before you buy **Will it fit my attic opening?** It is listed for openings up to 25 x 54 x 11 inches. Compare those limits with your opening before buying. **How is it installed?** The instructions say to place the cover over the attic stair opening and staple it to the door frame. **Can I still access the attic?** Yes. A zipper provides access through the cover, though buyer reports about zipper durability vary. ## When it makes sense Choose this cover if your priority is adding an insulated, zippered barrier over an attic stair opening and your measurements fall within the stated fit range. It offers a more enclosed approach than focusing only on a hatch’s perimeter, while still allowing access through the zipper. If you rarely use the attic, zipper convenience may matter less, if you use it often, the mixed reports about zipper longevity are worth weighing alongside the fit and stapled installation. ## Images ![DGSL Attic Insulation Cover for Attic Stairs, Zippered Aluminum, 25 x 54 x 11 in — 1](https://www.ofertitastop.com/i/NqZ83MgthG4uciuRii3l60VDCZrt5FI82BpcMY_kqDr2AWGESwmu6QA9yWCNQ_Vbn_XIEPdqI3fdQejKa_DNsljJo6fiM6oPCDJ_u8VOz4w_QZV_oewOrRA4Uw.jpg) ![DGSL Attic Insulation Cover for Attic Stairs, Zippered Aluminum, 25 x 54 x 11 in — 2](https://www.ofertitastop.com/i/CrUJQLXLzirdI2M6yLciqlvoeLM8yX-Sh50_WFosutdiy5pXeS5j6EEcGePnOa_rjukp-cVG3rB8IJaj06vFcEKa-PJY854mdqwvdVKT9xR3xO-KzEh7liF_Ig.jpg) ![DGSL Attic Insulation Cover for Attic Stairs, Zippered Aluminum, 25 x 54 x 11 in — 3](https://www.ofertitastop.com/i/PRmKiQVd3caBVkchuCP4Drzk7vVARCeU_bviS4M82uGWZtCl-9AAW_VEGfx3x4RTk6W-bxLR3q9vfXnx8iD-SltZFZ1gJ1WGxjCPpbLC4BgMWkXPVngcPbaDNw.jpg) ![DGSL Attic Insulation Cover for Attic Stairs, Zippered Aluminum, 25 x 54 x 11 in — 4](https://www.ofertitastop.com/i/cjYBwszm5xq1GIDIMm7oZLyWgRd0PYyQAk6vvxAHDjwx3r4a_HraQVZFEr9tUtEb2kZez43I0tb2fkhcjSCW1AAgvWmOwYIxFpHWa4EyhmHZnZdMzE7sjWzqbA.jpg) ![DGSL Attic Insulation Cover for Attic Stairs, Zippered Aluminum, 25 x 54 x 11 in — 5](https://www.ofertitastop.com/i/zZ9Fkxlt06poxswi8KFzUPu96NFo9U1lNbwm5_eoOwOGVfilJuCu7CE63tgfnh1LmcoWodSDSyyIbFGNryJI98yvN_OcUkr-5yxAAUnw4msqTpAQgb-EF1mmGA.jpg)
