Questions & Answers

how many square feet will this cover?

Asked by: goodyz
LookingForInsulation is incorrect. He forgot the multiply by 12 one more time. It's around 360 sf as btayso said.

Why don't you clearly state up front the number of batts per bag so a person doesn't have to spend an hour trying to figure out how many square feet per bag?
Asked by: BobT
I had this question, but looking at the description & specs I realized that one bag covers about 30 sq. ft. - at least for the 15 inch vs. 23 inch. This makes sense, as you can go immediately from the amount of space you want to fill.

How wide is it

Asked by: Lon
I have a piece of it right here. It varies from 15" to 15 1/4". The stud or joist bay is 14 1/2". It is made wider to provide a friction fit and so there are no gaps at the edges. When you install it, DON'T push the edges in and leave them that way since you are reducing the insulating value. You want it to be flat across, not pushed in at the edges and bulging out in the middle. Compress the edges toward the middle as you install it. If you need to cut it across or the long way, always made it about 1/2" larger or a bit more. I have installed several hundred sf and I love it. MUCH better than the O-W thermafiber batts. That stuff is crumbly and messier than RockWool.

Will this install on a ceiling in a basement and stay up?

Will this install on a ceiling in a basement and stay up?
Asked by: Di
Its oversized material (by approx. 3/4" width wise) to provide a good pressure fit between regual 16" or 24" oc framing. For smaller spaces measure the physical space and trim the material so its approx. 3/4" wider to provide that friction fit
