Customer Reviews

100 sq. ft. 30.75 ft. x 39 in. x 2 mm Underlayment is rated 4.3 out of 5 by 12.
Rated 5 out of 5 by from Incredibly easy to work with; high quality Five months ago, I renovated a play room in my house with new wood laminate floors. I had never done this before and so I spent so much time researching the type/color/cost of the wood laminate, that I didn't really consider other stuff, like floor underlayment. I just grabbed whatever looked nice and was of average price. Recently, I finished renovating my loft. This time I used a different floor underlayment (floor muffler). There was a huge difference with the ease of installation (the foam was easy to align and overlap; easy to cut; adhesive tape pre-attached to foam prevented shifting; no crackling foam noises!). I had a lot less frustration when working with this green foam. Plus, I swear the loft sounds quieter when i walk on it than my play room. (The play room has this clicky, plasticy sound when I walk on it). Anyway, I highly recommend you research and compare floor underlayments. For me, Floor Muffler was incredibly easy to work with and I found it dampened foot noise very well.

Rated 5 out of 5 by from High test results for sound reduction & MADE IN AMERICA I recently did our family room with laminate flooring. The salesman recommended Floor Muffler because it is the best in underfloor foam. I found it very easy to work with and I think the results are great. Also, very important to me considering todays economy, it's MADE IN AMERICA. I'm told the only one.

Rated 5 out of 5 by from This product is amazing! I just purchased this product at a Home Depot store near my home in PA and cant not believe the performance! We replaced the laminate in my sons room. Before it had another product under it with some beads that leaked all over and did not remove the hollow sound. After the FloorMuffler was installed my entire family cant believe its actually laminate floor! it sounds like solid wood. Thank you so much for starting to cary this....

Rated 5 out of 5 by from Excellent performance - Made in USA! I have had this product installed for over a year now under my laminent flooring and I have been very happy with the performance. The floors are quiet, which was my main goal; I did not want that 'echo' you hear with some laminate flooring installs. Installation is a no-brainer... The best part is, this stuff is manufactured in the USA!!

Rated 5 out of 5 by from State of the art I own numerous high end residences and have used the Floormuffler in each one. I've seen other knock offs but no other products performs as well. Great sound quality and easy to work with. So glad home depot stated carrying it.

Rated 5 out of 5 by from Best underlayment I could find for basement This was the best under layment I could find from Home depot. I've used the red with the white dots with my Pergo that I installed on the first floor of our house. I used the green Pergo under layment upstairs with that Pergo. I liked the moisture resistance and mold resistance features. Was very easy to install and the soundproofing is good too.

It doesn't lay flat and if you try to roll it backwards, it creases easily. The tape system is not the best. The pink poly slips around a lot and the seams don't line up. Maybe it was just me but I ended up tearing it up. If I were to use it again I would just tape it down with good tape and forget the pink poly and zip strip.
