Face insulation uses kraft paper vapor barrier to control moisture transmission between 
walls and floors

Customer Questions & Answers

will this cover the protruding parts of the stair when closed?

I have about 5" of stair protruding above attic floor when the stair is closed. Because the insulator is triangular I wonder whether it has enough space to contain this part without lifting up
Asked by: attictom
Yes - it goes up a foot or two. It's like a small pup tent with straight sides up to a pitched top.

Could this be used to cover an attic fan?

Asked by: Willie
If your fan is smaller than the size of the tent, I don't see why you couldn't use it for that purpose.

Is this product primarily used for an attic stairway door that leads to the actual living space of a home?

We live in Central FL and the door to our attic is in our (attached) garage, not the interior of our house (air conditioned living space). Although the attic door doesn’t close all the way and has a very large gap in the frame due to bent stair hinges, any escaped air from the attic just goes into our garage, which otherwise is sealed from the interior of the house because we have 2 solid/sealed doors between the garage and the inside of the house. We haven’t found an easy/inexpensive fix for the bent hinges/attic door gap, other than replacing the entire pull-down attic stairway. That said, do you think this product would do us any good? If so, why?

It would be best for an attic stairway that leads to storage space

Does this come any wider than 25-1/2, or is there something similar that would work?

Asked by: Tish
It says it's only available in one standard size to fit most openings. You could make your own with purchasing some duct wrap but making it any wider without some kind of extra support may fail to work properly. Because of the weight of the insulation, trying to make it any wider may could collapse the tent. Construct a lightweight tent with furring strips and fit insulation over top of it.

Attic Stair Insulator II 25-1/2 in. x 54 in. is rated 4.3 out of 5 by 305.

They are very efficient. The only problem we have is that we need to go into our attic every few months and find this product to be a little to flimsy. It could be made of a heavier grade of aluminum that did not rip on the drop down door hinges so easily. We would still recommend this product as it does an excellent job of insulating this area above the door.

Practically disintegrated after a year. plus, the metal "arms" on my pull down stairs hit the sides when the steps go up. I need to access my attic for storage and find it difficult to move when entering the attic. For now I have a cardboard box that provides support and this insulating blanket is laying over it. You might be able to build a frame that would support this insulating blanket but most of us don't have that sort of "project" in mind. We want a user friendly solution to our insulating problem. I am looking for a solution that better suits my needs and situation. Disappointed.

Rated 5 out of 5 by from A must have product for all attic pull down stairs I have an attic pull down stairs in the hallway on the second floor. During the summer it always feels warmer underneath the hatch and you can smell the hot insulation. I tried attaching insulation to the underside of the hatch and adding a strip of foam insulation around the edges to seal it off without much success. Then I bought this attic stair insulator on a whim while browsing through Home Depot. What a difference! The hallway is now the same temperature as the rest of the house and the smell is gone. I should have bought this years ago! It was easy to set up and position over the stairs entrance. It's just as easy to move to access the attic. The plywood floor in the attic isn't level and this insulator contours to make a good seal. Definitely buy this product.

It lower my Attic Stair ceiling area from a 85 degrees to a nominal 75 degrees. Took 30 mins to slip in and instantly sealed cool air loss to the attic by 10 degrees. Step 2 to take a load off your AC by lowering heat and moisture from your attic is also a must and I choose: (3) http://www.homedepot.com/p/Master-Flow-12-in-Weatherwood-Galvanized-Internally-Braced-Dual-Bearing-Wind-Turbine-GIC12WW/100059101?MERCH=REC-_-rv_cartempty_rr-_-NA-_-100059101-_-N

We have been struggling for several years to keep our second floor bedrooms as cool as our first level. We had installed a different type/brand of attic stair insulation kit but the AC always failed to keep up. We switched to this product on a day that had a high of 94 degrees and within an hour the upstairs AC unit started keeping up. I am amazed that something so simple could work so well. Worth every penny. *we did seal off just a few cracks with expanding foam as well

Open it up inside the attic and place it over the opening. I could immediately feel the difference just standing on the steps before I even got all of the way out of the attic! We've only had it a few weeks, so it's hard to tell what kind of impact it will have on our electric bill just yet. I have noticed the temperature change in the hallway since I put it up, so I know it's working.
