DGSL Attic Door Insulation Cover, Attic Tent 25 x 54 x 11 in | Energy-saving attic stairway door ladder insulator with zipper - desertcart.com

Review: Best purchase of the summer! Keeps the heat in the attic - The heat coming from our attic was awful. The AC mechanic recommended this and I’m so glad he did. Installation was easy and so far it seems to be helping. Usually the hallway that the attic stairs is in will get so hot and humid that the walls will start dripping. It also makes the AC work harder as it can’t keep up with the incoming heat. We’ve had a few super hot days and no weeping walls! The AC seems to not be struggling against the heat anymore! So happy with this. Not sure what it’ll be like when we have to go into the attic to retrieve decorations (and really go in/out of it) but even if it only lasts a year, it’s totally worth it for us to hold back the humidity and keep the temp down!
Review: Easy to install, noticed improvement immediately - I’m kicking myself for not doing something like this sooner. My attic access for one portion of my attic is in the bedroom hallway via a pulldown ladder that I had installed before we moved in. It has been a source of a “thermocline” or a change in temperature as you walk down the hall for years and I’ve often thought about somehow insulating it with weather stripping and foam panels or some other insulative boundary. We just had an extended deep freeze so I did some googling and found this product. for under 50 bucks it was here in 24 hours and installed in about thirty minutes with a staple gun. This included some trial and error since my opening was about a quarter inch larger than the insulator. I started in the corners making sure that it was stretched tight between each corner before stapling and then filled in the gaps between. Boy, what a difference! Noticed it immediately, instead of a cold downward draft the heat is now trapped, no cold draft in the hall and I have noticed the heat pump runs less frequently (since the thermostat is right below this ladder). I have used the access a few times and it is easy to zip and unzip and access the attic and it has fared well, seems durable and well made. This thing could actually pay for itself. Again, kicking myself for not doing this sooner. Great product, great price, easy to install and improved comfort, would definitely recommend.

### ⭐⭐⭐⭐⭐ Tack the corners first
*by A***R on August 25, 2026*

Easy install. It’s hot up in my Texas attic but it appears the quality and weight of the insulation will help keep the temperature down. It fit the drop down stair opening perfectly.
