Questions & Answers
Can this be used inside a chimney to insulate around a wood stove stainless steel liner?
Asked by Matt March 7, 2021Matt, due to fire risk, I would only use the commercially available double wall stainless chimney sections where you need insulation, like going through ceilings or walls
Can i use this with 2x4 walls?
Asked by KW February 28, 2021Hello KW, The R-23 UltraBatt is recommended for use in a 2x6 cavity. It will be difficult to compress the insulation and will reduce the products R-value. Thank you for your inquiry!
Does this contain formaldehyde? How much at what stage of process is it burned off during manufac...
Asked by Stretch January 15, 2021Owens Corning's regular binder Thermafiber® UltraBatt mineral wool insulation are manufactured with a binder that contains formaldehyde as an ingredient. During the manufacturing process, however, these products are cured at a very high temperature and virtually all of the binder formaldehyde is eliminated. The amount of formaldehyde in the finished product is less than 0.01% by weight. At this low level, and because we oven cure the product during manufacture, out-gassing of formaldehyde is extremely low and is not a significant source of formaldehyde when installed in a home or building. Thank you for your inquiry!

Asked by Jason September 29, 2020If you put osb sheathing, tyvek and siding, there is no need for additional vapor barrier on the inside.

A vapor barrier on ceiling is a good idea if it is not vented, but that also needs to be completely air sealed inside and out
