Great product, better price

eric from Collinsville, IL– Verified Buyer

Very easy to install and made a huge difference in noise compared to other underlayments. This product very similar to the orange for muffler sold at Home depot, the only real difference that I noticed is that this is a couple inches narrower but that isn't a big deal because you still get the same sqft. The price is also half that of the stuff from Home Depot. Our floor is 7mm thick and has been down for a couple months And we have had no issues and there is no dreaded clicking when you walk

Good customer service!

Laureen from Union, KY– Verified Buyer

Product was as expected, ordered 900 sq. ft. and it came quickly and got the job done! There was an issue with UPS labels getting confused and when I realized item was being shipped to the wrong state, customer service handled it and it arrived on the original delivery date! Awesome customer service!

Great price on a great product

Sabrina from Dallas, TX– Verified Buyer

We own a number of rental condos and we like to install wood floors. the problem is we don't like getting complaints from the residents underneath! So we tried the floor muffler as the underlayment under floating engineered wood and laminate floors. the first time we did it, we conducted a sound test and were amazed at how well it worked. It doesn't eliminate sound completely, but it's a pretty significant drop. We bought it first in store - then on Amazon when we found a better price - but from now on it will be Wayfair - by far the lowest price for this product!

Great Underlayment Great Price

C H from California

I am really happy with this underlayment. It is just what I was expecting and about $30 cheaper than the local stores. It is just what everyone else says it is. I love that it is rated the highest in noise concealment. It does tear easily, but if you are being careful it's not a problem.

Very pleased!

Dana from Orlando, FL– Verified Buyer

This underlayment was perfect for our floors! It went down smoothly and easily and really helped to soundproof the echo and click from our hardwoods!

Excellent product


I just finished my home remodel with this under my laminate floor and my family thinks I spend a lot more money than I did on my new floors! This product is great!

Great subfloor!

Jamie from ,– Verified Buyer

This is the same product as at large warehouse stores that sell it in red. Thick, sticks down well, makes a big difference in sound. GREAT price here on Wayfair with quick shipping too! Thanks!
