  • LUXURY VINYL PLANK & TILES: Find our QuietWalk Luxury Vinyl Underlayment specifically designed for luxury vinyl here
  • PERFORMANCE UPGRADE: Overall performance upgrade over poly foams and an economical alternative to rubber and cork, boasting impressive sound deadening ratings
  • WATER PROTECTION: DriWick technology prevents moisture damage to your floors by wicking away harmful moisture while the attached vapor barrier protects the overlying concrete or wood flooring from any attacking moisture
  • SOUND PROOFING: Superior noise reduction recycled fibers absorb sound and keep it from traveling to other rooms, makes floors sound solid underfoot
  • IIC (IMPACT INSULATION CLASS) SOUND RATING OF 71: IIC is a measure of how much impact sound (walking, kids playing, etc.) is reduced after traveling through the floor covering, underlayment, and building structure and emerging in the room below. The higher the number generally indicates better sound absorption qualities.
  • STC (SOUND TRANSMISSION CLASS) SOUND RATING OF 66: STC is a measure of how much airborne sound (speech, TV, stereo, etc.) is reduced after traveling through the floor covering, underlayment, and building structure and emerging in the room below. The higher the number generally indicates better sound absorption qualities.

  • MORE VERSATILE: Advancing the fiber blend technology of the original, QuietWalk Plus features more versatile applications with the special attached vapor barrier allowing glue down applications.

        Can I put this between plywood floor and sheet laminate in the bathroom? How would I attach to the floor? Then how do I attach laminate to the underlayment?
        ByJul 1, 2024
        1 Answer | 
        Answer This Question

        First, we need to determine the flooring covering. If the floor covering is laminate, then you can use this product. It does not get attached to the subfloor. If you are asking about a sheet vinyl, this product is not approved for use under sheet vinyl.

          Started noticing popping and crackling noises throughout the floor after using QuietWalk Plus underlayment with a stapled-down (18-20 gauge cleats 1-1/4” long) 3/8" engineered wood over OSB subfloor. The installation was done by professionals.

                Went down easy, seam tape works well. Does a nice job with noise reduction under my new engineered flooring. However, I got two rolls and they were rolled up in the opposite direction. Not a problem but weird.

                Being a bit optimistic i decided to try this product and it seems to live up to its calling (purpose). The softness and barrier it provides seems to be really well through out and feels great. Time will tell if it lives up to its hype. Hit for now it’s great!!

                Easy to work with
                I picked this underlayment due to its sound dampening and vapor protection at a great value. I like that it's Greenguard Gold Certified, comprised of antimicrobial treated recycled fibers. The fiber and thickness was consistent throughout each roll, but roll to roll had a marginal difference. This was very easy to work with. For the flooring project to succeed long-term, prep work is key! I leveled our floors, which included both patch and planer. Happy with the end result and would use again.

                  DO NOT USE WITH ENGINEERED HARDWOOD!!
                  We spent $550 on this to go under our 1800 square feet of new engineered hardwood floors. We ended up having to pull all the floors back up to remove it!!! I'm very disappointed that they recommend this for engineered hardwood! It was so squishy that when you stepped on the end of one board it would separate from the end of the board next to it. That would cause the edges and corners to get chipped or rubbed off if sliding a chair, toys, or feet on the floor. I feel ripped off!!

                    Unusual application with great result
                    QuitWalk was used under our balcony hardwood flooring prior to being replaced almost a year ago. At that time my better half recognized the advantages and possibilities for the main house rugs over our salito tile runners in the hallway and asked for the underlayment to be used for a rug underlayment where we had tried felts, rubber, dual surface felt & rubber, etc. 11 months later she is please with the padding for holding place, perfect padding w/o the thickness which is not attractive.

                    Thick cushioning along with sound dampening!
                    Since the floating floor that we were putting in did not have any underlayment, I was forced to add it separately. This is a quality underlayment with many great features and attributes. It has an advanced vapor barrier, superior sound reduction, compression resistance, thermal insulation, and it is made from ninety-four (94) percent recycled materials so that makes it Earth Friendly as well. You also have several options for installation, you can float it, nail it or glue it. For my case it was float it. An unexpected positive extra feature was I didn’t need my knee pads as I was putting down the flooring because I was already kneeling on the cushioned underlayment. A couple of minor issues that I ran into was the taping of the instructions and details of the product to the roll, it taped all the way around it. And when I tried to remove the tape, it started ripping the underlayment. So, I had to carefully cut away the instructions and leave the tape, otherwise I would lose about 3 to 4 feet of underlayment. A simple plastic wrap would work instead of the tape to keep the instructions and the roll wrapped. The other minor issue was it felt like there was small pieces of dirt or some foreign objects that I felt as I was unrolling it. So after cutting it to size I swept the underside and then the top side and the floor to make sure that I was not getting any foreign objects trapped underneath the flooring. The cushioning would probably be able to cover it, but I didn’t want to take any chances. It is very thick, and you do have use a sharp box knife, but that is a good thing that it is so thick. And my last and most favorite part about it was the way it was able to be taped together, it made it so easy to connect the two sections with the tape and the over layer plastic. A good underlayment to install and use for flooring that require it.

                    Dense, Quiet
                    A bit tough to cut, but once installed this QuietWalk underlayment is very easy to install. Scissors won't cut it. A box cutter needs to be very sharp. It's tough to cut because of how dense the fiber is, which is why this pad is so quiet. After installing the planks on top, there is no echo or hollow sound to the flooring. I can without reservation recommend this product for use under your laminate.

                    Great underlayment!
                    This is 100 so of great underlayment for my new flooring. I was looking for something more substantial and this is definitely it. It provides a cushioning underlayment as well as the water barrier to keep the new flooring dry and well protected. This product is exactly what I have been looking for and I am very happy with my selection and I am sure it will protect my flooring investment.

                    gives the floor a professional feel, not hard but not soft and quiet
                    I'm about to install an engineered hardwood in my master bedroom.  I have had two opinions about underlay, one is for it and another is against it (meaning no underlay).  So I set up a little test first to see if I first want underlay and second which one do I want.  I set up a short walk test as I enter my master where part of the new floor is on underlay and the other isn't.  I know for sure I want underlay.  As to the second question, this underlayment is great.  There's a distinct professional feel to that part of the floor, it is just right not hard like when directly on the slab.  I like the self stick edging, but my guess I'll still need some edge tape.  Overall this underlayment gives me the response I'm looking for from the flooring, solid but not hard and quiet when walked on.  This will be in my master bedroom, so I'm not worried about other issues of concern in heavily traveled parts of the house.  It's perfect for my requirement.

                    Easy to install
                    I can’t really speak to the quietness of this on a first floor (over a basement) application because I installed it in a basement over slab. This is a storage room that I am “semi-finishing” with wall insulations and laminate. I laid down dimpled subfloor covering and then installed this in the opposite direction. It goes down super easy and is easy to cut. The adhesive strip held really well, enough to hold tight, but not so bad that you can still reposition it without tearing. My daughter actually laid down on the laminate said “wow, this is warm”. She was expecting it to be cold like the rest of the basement.
