Rated 3.0 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by Great Product Great to see this product is back!! I used this in my daughter's room 12 months ago - I added to the floor, and I also used this on the wall between her room and the master bedroom (sandwiched between the sheet rock). As far as the wall, I cannot hear any anything (voices or TV) between our rooms, but if I knock on the wall, you can hear a muffled knock. I ran out of this product on a portion of the floor, so a part of her room does not have this - I used a barrier with carpet underlayment as the installers were waiting. Even so, it's much, much quieter than before. This has a rubberized backing with a felt lining, and it is thick and HEAVY - it's almost too heavy for one person to pick up, which tells me this is high quality because of the thick rubber. They don't tell you this, but I would say to ensure the maximum sound proofing, get some sound muffler calk tubes to seal where the edges meet, and then add the tape. I have heard of some folks adding a second layer diagonally to get almost complete quietness....i'm seriously thinking of doing when get hardwood installed upstairs. The only down side is you need to order this product and make sure you have enough, and they should provide the calk or something to seal the edges....I could not find this product anywhere other than HD's website.

Rated 3.0 out of 5.0 by somewhat effective but expensive We had ours installed by a flooring contractor in our second level apartment. There was a noticeable difference but it's not soundproof. I would use it again if the product wasn't so expensive. 75 cents per square foot is too expensive for what it does. April 29, 2014
Rated 1.0 out of 5.0 by does not work under carpet I got this hoping it would reduce airborne noise coming from neighbors downstairs. I was looking for something inexpensive and easy to install since I live in an apartment. The installation could've been easier except I had to move all my furniture out of my room. Now I feel like it wasn't worth it. There is no difference in the noise level coming thru. I can still hear their mumbling voices and their TV. Wish I could return it, but of course I had to cut it in order to install it. Even if I could, I'm not moving my furniture again. feeling extremely disappointed. January 12, 2014
