Rated 4.0 out of 5 by 64 reviewers.
Rated 5.0 out of 5.0 by Great laminate instalation This underlay was recommended to me by a Home Depot associate as the best value for my money. He was right, this underlay performed as advertised. There were more expensive products, but I can't see any reason to spend more when this product does a great job. Noise control is excellent. When you walk on the floor there is no foot caused noise, and it goes down easy. Our installers were very pleased that we had chosen this product. October 28, 2014
Rated 4.0 out of 5.0 by Easy to install - would likely purchase again. the FloorMuffler is supposed to have the highest sound absorbency rating on the market at the moment. I can't really tell a difference between my old floors (with no sound proofing) and the new floors with underlayment, but i've only had them completely installed for a few weeks - i'm hoping a few more months of use will make the purchase and installation time worth it. We bought two rolls for 148 square feet but with the odd angles we almost ran out even though it was supposed to cover 200sq feet - we ended up making some strange cuts and using up the scraps, which worked fine. I really like that since it was so flexible it was easy to cut in place with a box knife and get it right up against the wall (or under the sheetrock lip). It was very easy to install, just lay it down and peel the sticker strip. One thing that was difficult was that the interior of the roll(s) had been crumpled and was difficult to get to lay flat (even after using the sticker strips) until the floors went on top - we solved that problem with a few small boxes laid around the room. FloorMuffler was very light and easy to maneuver as well as very thin - so our new floors were able to very closely match up with the old ones. The instructions weren't very robust as this is a new product, but i wouldn't recommend walking around a lot as shoe tread leaves a semi-permanent indent. I don't imagine this would change the performance, but i suppose it could. April 22, 2013
Rated 5.0 out of 5.0 by Easy to install, quiet I don't understand the complaints about The FloorMuffler not laying down easily and the adhesive being weak. I used two rolls, one of them I reverse rolled the day before, the other I used right out of the bag. The one I reverse rolled ended up with lots of folds in it because it was hard to re-roll cleanly. The one I used out of the bag did curl a little, but that is easily combatted by placing planks on it to weigh it down. I had no issues with adhesion or butting the rolls up to each other. I don't think it tears that easily. I did accidentally push a corner of a plank into it and it ripped, but that's my fault, not the products... This was my first ever DIY hardwood floor install, with just a little common sense, you should have no issues with this. BTW, it does seem to mute foot fall pretty well. February 7, 2015
Rated 4.0 out of 5.0 by Nice Product! This underlayment was very easy to use and install. My only concern was it seemed to rip easily. December 10, 2013
Rated 3.0 out of 5.0 by Not Worth the Price This is the third click lock floor I’ve installed over a concrete slab in my home. For the first two I used the cheaper semi-transparent foam muffler that gave the floor a dull sound when walked on. For the last job I used 5 rolls of this more expensive muffler hoping to get a floor sound that simulates solid wood when stepped on. The results are mixed. For the first two jobs I laid the muffler parallel to the wood, one piece at a time as I worked across the floor, and had no problems. For the last job I followed instructions and laid the muffler perpendicular to the floor, which meant I had to lay it all before starting the flooring. That turned out to be a significant problem. As many have already said, the expensive muffler tears easily. I scuffed it with tools, knocked holes in it when setting wood sections in place with a tapping block, cut it while moving wood secions, and even punctured it while walking on it with tennis shoes. Catching the seams with tools, boards and my feet was also a continual problem. Although I taped scuffs and holes in the muffler with clear packaging tape, the end product probably had no more barrier integrity than the cheaper muffler laid parallel to the wood boards. The final product has a walked on sound more like a solid floor, but it turns out that just means noisier. The floors with the cheaper muffler now sound pretty good in comparison. All in all, I’m not sure this product is worth the premium. February 20, 2015
Rated 2.0 out of 5.0 by laminate underlayment Just want to say if you are an amateur - this takes two people to roll out and lay. When it is taped together using the attached strips watch for overlapping - even when you think it is not. Highly recommend masking tape instead. Used another kind for my first installation that was much easier March 25, 2015
Rated 1.0 out of 5.0 by Floor Muffler underlayment We installed over 900 square feet of bamboo flooring on top of the underlayment in all bedrooms and closets. I don't think the floor muffler underlayment does a good job of reducing the noise of the sound when you walk on it or knock it with your hand I wish I would have went with the Bellawood Premium underlayment. the floor also moves a lot in different areas when walking over it and makes cracking noises very disappointed especially since it was recommended the best and I payed more for it.
