CUSTOMER REVIEWS

Rated 5 out of 5 by 9 reviewers.
Rated 5 out of 5 by Better than fiberglass Very easy to install and cut with a bread knife. Only downside is it more time consuming to install than typical fiberglass and the price difference. However no staples are required. Works extremely well as a sound dampening device. December 2, 2014
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 Far superior to fiberglass It's far superior to fiberglass. Easier to install, better insulator, far less air penetration possible, safer, non flammable, and a great sound barrier as well. I'll never use fiberglass again. November 2, 2014
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
