CUSTOMER REVIEWS

Rated 5 out of 5 by 7 reviewers.
Rated 5 out of 5 by great product Excellent sound barrier, easy to cut and install, tools required rubber gloves and bread knife,tighter fit in wall cavity, higher r value over fiberglass insulation July 3, 2013
Rated 5 out of 5 by Some of the best insulation This is some of the best insulation that I have ever used. In my mind it is second only to sprayed foam insulation. Easy to work with, easy to cut (just use a butter knife), less itchy than fiberglass. Higher R value than fiberglass for the same thickness. It costs a little more up front, but it pays for itself in my mind. January 21, 2012
Rated 5 out of 5 by Great product! Not much to say but this is 10x better then the pink or white insulation. Fireproof, mold resistant, good for sound insulation, and it doesn't itch as much as fiberglass insulation. It is just a more expensive than comparison but well worth the money! October 30, 2011
Rated 5 out of 5 by great product, easy to install So easy to install. Precise cuts with a bread knife, making it easy to get behind electrical boxes for more effective insulation. Held in place by tension, no stapling. If a stud bay is wider than 16" OC, you can simply cut a strip to make up the difference. Higher R-Value per inch than fiberglass batts, plus no itching. Price is a bit more than fiberglass, but ease of use and long term performance of the product makes it well worth the price difference. July 3, 2012
Rated 5 out of 5 by Great product, just what I needed Needed to build an enclosure in the laundry area of my garage. I planned to stack my pellets on the other side of the wall so not only was insulation needed, but I wanted the maximum fire protection also. This product fit the bill nicely and even though a bit pricier than, it was sooo easy to work with. February 16, 2013
