Rated 4.4 out of 5 by 9 reviewers.
Rated 1.0 out of 5.0 by Product fell apart installing Will never buy their products again. Told it was made in the USA and that's not entirely true. March 18, 2016
Rated 5.0 out of 5.0 by I used as ceiling sound barrier Good product. I wish when I built my house I would have used it under all flooring. February 17, 2015
Rated 5.0 out of 5.0 by Surprisingly effective sound insulation. Surprisingly more effective sound insulation than the carpet and pad we replaced. T.V., talking, and walking movement vibrations are muted again better than the thick pad and carpet. Easy to lay-out below the Hardy Backer, better priced than competitors, shipped to us in three days. Five stars. July 1, 2014
Rated 5.0 out of 5.0 by Great Product This product was easy to install. You could cut it with regular household scissors. I used it to fill in the spaces between the Quiet Warmth floor heating mats and the Snapstone tile. It was the same thickness as the mats so taping them together with duct tape (don't use the cheap stuff) was easy and putting the tile over it went well also. Price was very reasonable too. December 15, 2013
Rated 5.0 out of 5.0 by Great investment Installing porcelain tile over concrete slab. Quiet, warm, good price, quick delivery, (only 3 days), a little difficult working with long strips, easy to cut with scissors or a box cutter for long straight cuts with steel straight edge. Rent a 75-80# roller. Takes a lot of preplanning because you are not to walk on it for at least a day. Really, who cares about appearance when it is under the flooring? February 21, 2012
Rated 5.0 out of 5.0 by Great Price for product... I am revamping my entire apartment and am removing all carpet to put in bamboo flooring. I spent many hours online researching the products and qualities of each. Cork seemed to be the best, but comes with a hefty price tag. Found this to be both resonably priced and shipping was super fast. Such a difference with sound too!! I don't think the neighbors below will be complaining as much after putting this under the flooring... July 17, 2010
Rated 4.0 out of 5.0 by Just what we needed I had inherited this flooring job from my late father-in-law and he had already purchased the materials for the kitchen floor. We went about installing the bamboo flooring using the recycled fiber insulayment he had, but ran out. I looked EVERYWHERE for more of this, with no avail. Finally, cruising Home Depot.com, I found this perfect match. Thanks, Homedepot.com! February 19, 2011
Rated 5.0 out of 5.0 by very quiet Installed under nail down 5/8" bamboo. Had laminate with the cheap thin foam junk before and you could hear all the annoying noises i think about when i think of hardwood flooring. Long story short, echo's don't exist, the floor is warmer and it's a recycled product. May 11, 2011
