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.

QuietWalk Plus can be purchased without the antimicrobial additive from Green Building Supply.

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

QuietWalk Plus has only been tested and approved for use installed under laminate and wood flooring. In theory this would help to reduce noise transfer, but we cannot say for certain.

The difference between QuietWalk and QuietWalk Plus is the attached film. QuietWalk Plus has a specialized film designed to accept nails and adhesives so it works with floating, nail-down, and glue-down installation methods of laminate and wood floors. QuietWalk is approved for floating wood and laminate only.

QuietWalk Plus has an attached vapor barrier suitable for emissions up to 7lbs/1000sf/24hrs. If the emission rate of your slab is less, then you do not need an additional vapor barrier.

QuietWalk Plus is not approved for use with peel and stick tile or carpet. We recommend our QuietWalk Carpet Pad for use with carpet.

QuietWalk Plus is approved for use with radiant heat mats. We recommend our QuietWarmth Radiant Heat Systems.

QuietWalk Plus is not approved for use with rigid core vinyl flooring; we recommend QuietWalk LV for this application.

QuietWalk Plus has a built-in lip and tape system to seal the side seams of the product.

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.

QuietWalk gives you 360 coverage from the water above and below, allowing you to live life to the fullest and still have beautiful floors.

Featuring Exclusive DRI-WICK Technology

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.

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!
