Asked by Stretch January 15, 2021

Answer

Owens 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!

Answers

If you put osb sheathing, tyvek and siding, there is no need for additional vapor barrier on the inside. It is more important to air seal and apply Several coats of paint to finished interior walls. 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

It stays in place. No need for stapleing it to the lid. This product also gives me plenty of time and the option if I even want to drywall the lid because it stays between the beams so well.

Good but pricy insulation product. Easy to cut if needed and quick to fit to accurately framed walls. I assume a cutting knife is sold but I have my own. As always, a good dust mask and eye protection helps as the product seems to produce an irritating dust.

Dense really great insulation with sound deadening properties. Easy to put in without lots of dust and itchy fibers. Suggest a large serrated knife for cutting and still wear a mask because there is some dust that come off the rock spun material.
