Choosing The Right Insulation

Faced Insulation

Faced

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

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
The problem is not the height. This person has the same type of stairs I do, the stairs are not self contained within the opening when shut, it extends past the opening by a couple feet in the length direction, not the height. So the question is will this product accommodate the length direction? Thanks

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.

Got this on one of the Home Depot one day sales and I guess it was good for that price. It is simply a triangular tent shape that goes over the attic pull down stairs. It fits OK and stays up pretty good. The only real complaint I have is that the bottom edges are exposed insulation. Since this is the side facing you as you try to move it out of the way, you will most likely be touching insulation every time you access the attic. Also it relies only on the tent shape to stay in place. A strip of plastic or something to give a little bit of ridgidity would have been nice. If those two things were modified, I would recommend. Functionally it seems to work as needed helping to limit heat and cold from coming through the pull down attic door.

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.

Building my own insulation box would've cost more. This product is so simple to use, just unfold it and put it in place. Would be nice if it had a little more structure to it, but sturdy enough. When I close my stairs the end of it shifts out of place a few inches, so I'll need to tweak something so that the insulation stays exactly where I want it. It does seem to be providing the insulating factor, so that's the main thing.

The Owens Corning Attic Stair Insulator II has plenty of room for the folded stairs to fit. I was going to build something similar on my own using insulator foam board, but for the price this should do just fine. The only issue I have is I wish it was more rigid. If you access your attic stair often, I'm not sure of how well it is going to hold up if it is moved constantly. I may build a small frame to help with the issue. Other than that it seems to work like it should.

I love how the Attic Stairway Insulator keeps my closet under my attic stairs warm, but if I could change anything it would be to have the edges closed with the same material as the outside of the product. Every time you move the Insulator to go in the attic, insulation falls out everywhere. I am planning on closing the edges up with something like extra wide duct tape, but I feel you should not have to do this kind of product and price.

The weather is just now turning cold so I can't tell if it helps or not but I feel like it will. While I was up there putting the insulation in place it was getting warm from the heat that was rising so I definitely think it blocks the heat loss. I feel like it was an excellent deal (when I bought it on sale) and I hope it does a good job in making the house even warmer this winter.
