Easy to Install and Effective!
Size: 200 SQFT
I used the QuietWalk Laminate and Floating Wood Flooring Underlayment with Attached Vapor Barrier under my hardwood flooring, which was installed over a plywood tongue-and-groove subfloor. It was a fantastic choice! The installation process was straightforward and hassle-free. The attached vapor barrier provided peace of mind by offering excellent moisture protection, especially in areas prone to humidity. What impressed me most was the sound reduction – it noticeably minimized noise, making the flooring feel solid and quiet underfoot. The compression resistance also ensures long-term durability, which is a huge plus for high-traffic areas. Overall, this underlayment is a high-quality product that delivers on all its promises. Highly recommended for anyone looking to install hardwood or laminate flooring!

Great product.
Size: 360 SQFT
This is the very best underlayment. Not a cheap extruded foam, but a rel vapor barrier and padding for concrete floor installation of a floating floor. It also breaths, eliminating the threat of mold.

Perfect sound barrier.
Size: 200 SQFT
So thin and provides lots of sound proofing. Helped deal with an uneven floor where we pulled up old tile. I didn’t have to do as intense prep to even out floor because this filled in gaps and prevented movement. Would recommend their entire line.

Highly recommend
Size: 100 SQFT
We went to our local home depot store to get something that we could lay under out wood tiles and after gey convinced us that we needed to buy two types of sheets a moisture barrier and a cushion sheet. We ended up paying an arm and leg for our first guest bedroom. For our second guest bedroom we decided to look around for a cheaper way and came across this item. Two in one, not only is this a moisture barrier but a cushion. We biught it and laid it on our concrete floor and it has adhesive to facilitate this hideous process and makes it smoother for you to lay your wood tiles on top of it. I highly recommend and so does my husband. Will be buying for my next floor project. P. S. We saved money and time. Highly recommend

Better than the foam. Not for basements
Size: 360 SQFT
I used on my second floor under the laminate floor. It reduces noise but if your wife is walking around with heels it’s not going to stifle the clonking. I highly recommend this product

Must Have for new Flooring

The only way to go. Great quality and makes a HUGE Difference regarding the floor and how it responds. Pricey but well worth it and far better than the HD brand

Excellent Underlayment for flooring.
Size: 360 SQFT
Recently had a new laminate floor put in our first floor. We first laid down this Quite Walk Underlayment and then the floor. It worked great. It so easy to use and cut, very effective, great quality. My only problem I did not do the math correctly and had to order more, but it came quickly so no problem. I recommend this product to everyone.

Soft and quiet!
Size: 360 SQFT
Worked well, bought for our new flooring and definitely makes the floor "softer". Cushions the floor and does provide some noise cancelation and was easy to install.
