Good product & good price.
Would RecommendIt was easy to use. We had to cut down several pieces and that went fine. One roll was all we needed for our project. Very pleased with the insulation.

Attic Insulation
Would RecommendThough this order was delayed 3 weeks, this product was great to add on top of the old blown-in cellulose insulation. I had to make 13-foot cuts, which is great for no leftovers on a 39-foot-long product. Can already tell the difference upstairs from the attic upgrade.
