Features

Superior Sound Reduction

Recycled fibers absorb sound and keep it from traveling to other rooms. Makes click-together floating floors sound solid underfoot.

Water Protection

Recycled fibers allow installation over concrete to “breathe” - managing vapors from becoming bulk moisture. The attached vapor barrier protects the overlying floors from harmful moisture.

Compression Resistant

Dense recycled fiber structure supports the click-together mechanism and will uphold its supportive configuration under the consistent traffic of the overlying floor.

Smoothing Out Imperfections

Firm and supportive, but flexible enough to form around subfloor surface roughness, helping to cut down on extra subfloor surface prepping time.

Insulating Value

Provides additional comfort to the entire home during seasonal temperature changes.

Approved for In-floor Heating Systems

Allows heat to permeate evenly while helping to protect the floor covering material from thermal shock.

Made From Recycled Material

A patented manufacturing process repurposes post-industrial materials into high-performance underlayment.

Certified Clean and Safe Indoor Air Quality

No VOC's (Volatile Organic Compounds) or off-gassing from materials.

Advancing the fiber blend technology of the original, QuietWalk Plus features an advanced attached vapor barrier, increasing the versatility by making glue or nail down applications possible. QuietWalk Plus boasts exceptional performance at reducing unwanted traveling noise and superior moisture protection, while offering proper support to the structure of your flooring. This underlayment can be installed over wood or concrete subfloors, and is designed for use with laminate and hardwood flooring.

Use with hardwood, laminate, and bamboo. QuietWalk PLUS is for nail-down, glue-down, and floating applications. Not approved for use with luxury vinyl flooring. Please use QuietWalk LV for that application.
PERFORMANCE UPGRADE: Overall performance upgrade over poly foams and an economical alternative to rubber and cork, boasting impressive sound deadening ratings
MORE VERSATILE: Advancing the fiber blend technology of the original, QuietWalk Plus features an advanced attached vapor barrier, increasing the versatility by making glue or nail down applications possible.
WATER PROTECTION: wicks away vapor emissions from the concrete and allows the moisture to evaporate without causing mold or mildew. The attached vapor barrier prevents the harmful moisture below from damaging your floor covering, while also preventing topical "accidents" from soaking into the underlayment and staining your subfloor.
INHIBITS MOLD GROWTH: Treated with proven and safe anti-microbial to inhibit mold and mildew growth providing a safer indoor air environment in your home.
SUPERIOR NOISE REDUCTION: Recycled fibers absorb sound and keep it from traveling to other rooms, making floors sound solid underfoot. IIC 71 STC 66
WARMER FLOORS: Provides a blanket of insulation between the cold subfloors and your floor covering. Giving you additional comfort to your entire home during seasonal temperature changes
APPROVED FOR IN-FLOOR RADIANT HEAT SYSTEMS: Allows heat to permeate evenly while helping to protect the floor covering material from thermal shock. Achieve in-floor heat with our QuietWarmth Radiant Heat Systems.
APPROVED FOR PAD-ATTACHED FLOORING: QuietWalk's exceptional compression resistance assures that the underlayment will maintain its shape over time and will not contribute to floor decoupling, especially in high traffic areas..
EASY INSTALLATION: Roll out and join seams with built-in lip and tape system. No additional underlayment tape required.
LAYS FLAT DURING INSTALLATION: No annoying roll back during installation. Dense fiber pad lays out flat and stays flat unlike most foam underlayments. Join seams with built-in lip and tape system. No additional underlayment tape required.
LIFE TIME DURABILITY: Properly supports the joints of the floor and maintains its shape and lasting support for the life of the floor

Thank you for reaching out. That is not an approved application for QuietWalk Plus.

Thank you for reaching out. In theory this would work, but we have not done any testing in an application such as this to know for certain how it would respond.

Thank you for reaching out. This is not an intended use of the product and we don’t have any testing data to determine if it works or not. However, there is nothing about this application that concerns us. It should help dampen some of the noise being transmitted to the room below.

Thank you for reaching out. The only difference is the film. The film on QuietWalk Plus is designed to accept nails and adhesives so it works under floating floors, nail down floors, and glue down floors. The standard QuietWalk is for floating floors only.

Thank you for reaching out. You will need to perform a calcium chloride test on the concrete slab to determine the emission rate. If the emission rate is less than 7lbs/1000sf/24hrs, then you do not need an additional vapor barrier.

Thank you for reaching out. Those are not approved applications.

Thank you for reaching out. Yes, the QuietWalk is approved for use with radiant heat.

Thank you for reaching out. Standard QuietWalk is not approved to be used under any thickness vinyl plank. The product you will want to use is QuietWalk Luxury Vinyl. https://www.homedepot.com/p/QuietWalk-100-sq-ft-x-3-ft-x-33-34-ft-x-1-4mm-Acoustical-Underlayment-with-Vapor-Barrier-for-All-Vinyl-Plank-Flooring-QWLV100/306837487

Thank you for reaching out. The seams stay together with the factory installed lip and tape system. You need to check with your flooring manufacturer for approved substrates and check if they allow for tile. As for approved floor coverings, this product is approved for use with laminate and floating hardwood.

Like Walking on a Cloud!

[This review was collected as part of a promotion.] We recently ripped up the existing carpet in my upstairs guest bedroom & decided to use this roll of underlayment to pad the subfloor befor installing brand new laminate. I can easily say this was one of our best purchases since beginning our little remodeling journey! The laminate we decided to install wasn’t the highest quality, but this padding brought it to the next level. You can definitely tell the difference between the soundproofing in this room compared to the others in our house. It also gie more support if you’re someone who likes to go barefoot. Would definitely recommend!

Good Quality, Fast Shipping

We had used Quiet walk products years ago when we first started remodeling our home. They have held up beautifully and did everything they were supposed to do. So, when we wanted to finish the rest of the floors in the house we knew we wanted Quiet Walk products again. The only complaint I have is the adhesive that comes with it to connect the layers is a wrinkly mess and just becomes frustrating. It may be user error, but 3 of us tried and all of us ended cursing and frustrated. We decided to go over it with duct tape and it’s great. It just would be really nice if it was a better system trying to stick it together so one didn’t have to also purchase duct tape.

Also wanted to note that the shipping was great. We’ve bought twice from the same distributor and projected arrival was 10-14 days later but both times they’ve arrived with in 3 days and that was SOOOO helpful!!! Thanks so much for the great service!

Quietwalk Plus

[This review was collected as part of a promotion.] The quietwalk plus floor underlayment allowed us to add an extra layer to our floors before vinyl planks were added. This provides an extra layer to your floors to deter any noise or squeaking when walking on the floor.

Top & Bottom Side Defense

With its uninterrupted vapor barrier, QuietWalk protects your floor from top side water & keeps it looking like new. QuietWalk's antimicrobial treated fibers protect your floor from harmful trapped & pooling water below by accommodating concrete's natural venting process.

Impact Noise Protection

Ambient Noise Protection

STC (Ambient Sound) - 66 QuietWalk creates a barrier that reduces noise transmitted to upper levels by everyday activities, so can you do what you love without worry. *The higher the STC number, the better the noise control!

Healthy Living & ECO Friendly

Unlike many current household products, QuietWalk doesn't release harmful VOCs (volatile organic compounds) or chemicals which keeps your air clean and you healthy. QuietWalk's dense, fibrous pad is also constructed by recycling textile materials that would have otherwise been thrown away!
