Can i double up the r15 3.5 inch ultrabatt exterior rated and put in attic ceiling?

Asked by Tableauman October 22, 2020
1
Answer

Hello Tableauman, As long as you have proper ventilation, the addition of more insulation to the attic floor is acceptable. If any batts are faced, they must be in contact with the drywall ceiling in the attic. We suggest looking at R-15 fiberglass as that will be a lighter batt that will be less likely to compress the bottom batt. Thank you for your inquiry!

is this formaldehyde-free?

Asked by jackobean October 15, 2020
1
Answer

Hello jackobean, Thermafiber UltraBatt is 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!

Excellent product. I bought the saw that was linked with the insulation and it does an excellent job of shaping and cutting the batt. Very easy to squeeze and place between the wall studs and behing the wires crossing thru the studs. Light to handle and move around
