Had it all stapled in place in about 10 minutes. And the difference it makes is shocking! The door to our attic stairs never closed all the way... there was one edge that had about a 1/4-inch gap which would let heat into the house in the summer and would let heat escape up into the attic in the winter. This little baby solves that problem once and for all. We installed it on a sweltering 96-degree July afternoon, and the minute it was in place, you could literally feel how much cooler it was standing directly underneath the attic door. Well worth the money. I wish I would have bought it years ago! Review: Good item, but important to install correctly. - I noticed a very significant improvement after installing this, I'm in Houston and it's a heatwave, so I needed something for both my house and my mother's house. (I bought 2 of these at once) I'm not sure about it's durability (It's plastic after all), but it seems OK. The zipper....I'm not sure about. But if you don't go up in the attic constantly it's probably OK. It is very important to properly install it. I used double sided duct tape and staples. Make sure you remove any staples/nails that are sticking out (or pound them flush with a hammer). Wipe it down to get rid of any dust that would prevent your tape from sticking. Unfold it, have it ready ABOVE the opening. Put the tape all the way around, make sure to press it onto the sides and remove the plastic covering the outer part of the tape.(I had trouble removing the plastic on my tape because of the heat so I had to put it in the refrigerator to cool it off a bit first). Carefully line up the bottom of the cover with the bottom of the tape and press it tight. Do that all the way around. In the CLOTH part (the black edge around the bottom), staple to the sides. (I would avoid stapling directly into the plastic) So with the double sided tape I didn't have to use extra duct tape around the bottom to seal it. Hope this helps someone (the instructions they include are not very precise). ## Features - Easy & Quick Installation: All you need to install our attic cover insulator is a pair of hands, 10 minutes & a staple gun (not included).

The depth of the ladder opening is 6". Will this product fit?** A: You opening and ladder folds sound standard. This product should fit. I was extremely pleased with mine. Suggest you buy an electric staple gun as you will be using a lot of staples. **Q: The actual opening of our attic hatch is 20.5 by 28 inches. Will this work?** A: This product is designed for a larger opening, 25 X 54. It can be stapled to the wood frame that surrounds drop down stairs. Amazon has an R-20 Attic Hatch Insulation Cover that looks like it can be trimmed to do what you want. Look at Energy Guardian HU1-20-10A. I’ve neither seen nor used this product, but I would give it a try. Attic hatches are literally radiant ceiling heaters all summer long. **Q: Directions were NOT included!!** A: Hello, please email ewisecustomerservice@gmail.com, you have purchased the item from another seller who has not included instructions. thanks **Q: What is the warranty on this product?** A: No warranty information is provided you would need to contact company directly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Really great product! *by L***E on July 15, 2023* This product is very well made and is a snap to install.

The wider step makes the stairs extend higher in the attic when folded-up than the original stairs. That means that the attic stair insulation cover must be high enough to "clear" the folded stairs. This stair cover meets that criteria. The side walls are 11 inches high, but the installation requires that the sidewalls be stapled to the INSIDE of the attic opening frame...BELOW the attic floor elevation...so some of that 11 inches in height is lost by the installation method. That said, it is still high enough to clear the folded-up stairs. Installation was easy with a manual staple gun. The stair cover fit exactly within the dimensions of the attic opening. This cover is a significant improvement over my previous attic stairs cover because this cover has a higher R rating and this cover stays in place when the extra wide stairs are folded-up. Update 14Dec25: This is an awesome product that has held up well - shows no signs of wear and tear - both zippers are working fine...and it continues to provide needed insulation. This was a good purchase in 2020 and I am reminded of that with every trip to the attic. ## Frequently Bought Together - Energy Wise Attic Door Insulation Cover, 25″x54″x11″, Extra Thick Double Bubble Attic Insulation for Pull Down Stairs, Air Tight Attic Stairs Insulation Cover with Easy Zipper Access - Duck Brand Double-Sided Duct Tape, 1.4-Inch by 12-Yards, Single Roll, Blue (240200) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/90463133-energy-wise-premium-attic-door-insulation-cover-25-x54-x11](https://www.desertcart.jp/products/90463133-energy-wise-premium-attic-door-insulation-cover-25-x54-x11) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-16*
