Owens Corning Attic Stairway Insulator

I was losing a lot of heat from my pull down stairs in the winter and pulling in heat from my attic in the summer. This fixed the problem. Read the reviews and see the existing installation tips. They were very helpful.After using for a while, here are pros&cons. Pro-Super easy install with no tools. Fits opening well, stays in place, insulates okay.Cons-Bulky, when I move it to get into the attic, I have a little fiberglass in my hair/eyes. My attic storage is pretty full. I have to wad it up to get access to my stuff so it is inconvenient.Conclusion. If you don't have or want to use any tools, this will be a great improvement. If you do have a staple gun (not a stapler for papers:), go with something like the PANADY Attic Stairs Insulation Cover. The Panady is light weight and easy to install and use. Just be gentle with the zippers and it should last a life time. Both covers stop the air flow which accounts for most of the heating/cooling loss. Thickness is not a big issue.

This thing is great! .It is made of 3" thick R10 fiberglass insulation covered with foil, and (when unfolded) is the size and shape of a child's pup tent. It covered our 26" X 52" attic opening perfectly, and has enough room to accommodate the ladder when it is folded back up. Installation was dirt simple, even for this 71 year old man: I just stood part way up the unfolded ladder, pushed the "tent" up into the attic, unfolded it over the opening, and moved it around until it fit evenly. I adjusted the bottom edges of the tent a bit here and there until no light could be seen shining underneath (luckily, we have attic light fixtures that can be switched on from the hallway). Total time was about 5-7 minutes from start to finish. We can definitely feel an improvement in the temperature of the hallway underneath it, and even in the bedrooms adjacent to it. As an aside: some people have complained about the bottom edges of the "tent" sides not being covered, thereby leaving the insulation exposed. IMHO, that might actually be a benefit, since the less rigid fiberglass batting can spread out and flex around, and therefore cover gaps or uneven places better than a more rigid edge might. And, the tent seems fairly sturdy, given the nature of its construction and light weight. So long as one is not going into the attic on a frequent basis, and uses due care when they do, I would expect the thing to last for years. I unequivocally recommend it.

I've always been very mindful of energy usage for the simple idea of energy independence. I was hesitant to purchase this product due to the costs and insulation value but was being lazy about building a R60ish cover myself.I'm honestly extremely impressed with this product even with it's insulation value. Here's my before and after numbers (using an infrared thermometer)...Before (around 8pm):Outdoor Temperature: ~40 degreesAttic Temperature : ~50 degrees (have a remote thermostat)Indoor Ambient Temperature: 70 degrees (indoor portion of remote thermostat)Average Ceiling Temperature: ~66 degreesAttic Ladder Door Panel: ~58 degreesAfter (around 11pm):Outdoor Temperature: ~28 degreesAttic Temperature: ~40 degreesIndoor Ambient Temperature: 70 degreesAverage Ceiling Temperature: ~67 degreesAttic Ladder Door Panel: ~66 degreesNow, I didn't modify or do anything special and I do have gaps at the base (as well as a loose floor in the attic). I do agree with everyone else that the product is a bit flimsy and could use some modifications (stronger support, better base coverage, etc). Though, standalone by itself I'm still quite impressed. Considering the outdoor and interior attic temperature dropped over 10-12 degrees, the attic ladder door increased about 10 degrees. Granted I know there's a still areas that need to be sealed but I'm seriously impressed on how I just simply placed this down without modifying it and how much heat it's retaining (or not losing). I can't provide a BTU number just yet but the numbers don't lie and it will definitely save wasted energy.I plan on further sealing the loose gaps but with the current stats, I highly recommend this item! (I even paid the higher price for it). I'd rather pay now and save later than to continue to lose more over the long term.
