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

Dri-Wick technology allows 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, helps 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 and pre/post-consumer materials into high-performance underlayment.

Certified Clean and Safe Indoor Air Quality

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

Competitively Priced

An ideal upgrade from 2-in-1 polyethylene or polystyrene products and is less costly than most frothed foam, cork or rubber underlayment with similar sound numbers.

Float It

Can be used with a variety of floating floor types.

Designed for floating laminate and wood flooring, QuietWalk’s recycled filaments are specially processed to cushion the floor, absorbing sound and reducing unwanted noise. This helps make floating floors sound more solid underfoot and helps to keep sound from traveling to other rooms. Although it can be installed over wood or concrete subfloors, QuietWalk is especially beneficial over concrete, where the exclusive Dri-Wick® technology will effectively manage moisture vapor emissions that naturally occur in concrete slabs.

Since QuietWalk and concrete are both “breathable” capillary products, vapors that are emitted will never accumulate under the pad into harmful moisture to the flooring. The Dri-Wick® technology will wick away harmful water vapors while the attached vapor barrier protects the overlying flooring from any attacking moisture. With QuietWalk flooring underlayment you get better water protection, as the fibers manage harmful moisture concerns.

Available in 3′ x 33.4′ (100 sq ft) or 6′ x 60′ (360 sq ft) Rolls

Use with laminate, floating engineered and floating bamboo. Underlayment is for floating or "click-together" floor applications (Flooring that required no glue or nail down.)
WATER PROTECTION: Exclusive Dri-Wick Technology of the recycled fibers allow installation over concrete to manage vapors from becoming bulk moisture. The attached vapor barrier protects the overlying floors from harmful water.
SOUND PROOFING: Superior noise reduction recycled fibers absorb sound and keep it from traveling to other rooms, makes floors sound solid underfoot. IIC 71 STC 66
APPROVED FOR PAD-ATTACHED FLOORING: QuietWalk's compression resistance exceeds the requirement for pre-attached flooring that is greater than 29 psi per ASTM D1667. The high compression resistance assures that the underlayment will not contribute to floor decoupling especially in high traffic area.
LIFE TIME DURABILITY: Properly supports the joints of the floor and maintains its shape and lasting support for the life of the floor
LUXURY VINYL PLANK & TILES: Find our QuietWalk Luxury Vinyl Underlayment specifically designed for all vinyl plank applications
GLUE DOWN & NAIL DOWN INSTALLATIONS: QuietWalk PLUS's advanced vapor barrier is compatible with glue down & nail down installations
FLOOR HEATING APPROVED: Approved for all in-floor radiant heat systems allows heat to permeate evenly while helping to protect the floor covering material from thermal shock, achieve warmth with QuietWarmth radiant heat system
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.

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 is not approved for use with luxury vinyl products. We recommend QuietWalk Luxury Vinyl for this application.

That is not an intended application, but there should be no issue to use QuietWalk under an area rug.

QuietWalk has only been tested and approved for use over a substrate, below a floating laminate or wood floor. We have not tested it for use between layers of plywood and cannot speak to the suitability.

QuietWalk is approved for a concrete subfloor under laminate flooring and has an attached vapor barrier. You shouldn’t need an additional vapor barrier unless the moisture vapor emissions of your slab exceed 5lbs/1000sf/24hrs.

All of the underlayments in our QuietWalk family of products would be excellent in this application. They are all approved for use over concrete and under laminate flooring.

QuietWalk is approved for floating applications only. QuietWalk Plus can be installed in a double glued application with engineered wood.

QuietWalk can be used below a floating engineered hardwood floor. If you are planning on stapling your engineered wood floor, you would need to use QuietWalk Plus.

The QuietWalk family of products is GreenGuard Gold Certified to be extremely low in VOC’s and chemical emissions.

QuietWalk will absolutely help with that. It has an R-value of 0.58, which adds thermal insulation and keeps your floors from feeling as cold to the touch.

Easy to install underlayment

Perfect to place over tiled floor to lay the laminate.

by Renovations - Lowes Review

Helps with sound

First time using this product and it seems to dampened the sound. It was used on a second floor with no insulation in the first floor. Be careful moving around on this when laying your floor as it tears easy. Adds some cushioning to the floor too.

Nice product

I’ve installed laminate without an additional underlayment and didn’t like the hollow sounds underfoot. When doing my LVP install, I decided to use this product. It’s pretty easy to roll out and use. I first used a box cutter and then a stout pair of sissors to cut the rest. Taped the seams with Roberts seam tape. I definitely feel this product does it’s job. The floor feels solid without any odd noises. These are big rolls which make it easy to get coverage. I would recommend this product to anyone.

Best underlayment, also a moisture barrier

Thick felt underlayment and moisture barrier. I am replacing the entire floor of my downstairs with a bamboo engineered hardwood and doing the job myself. This underlayment is super easy to work with. Easy to roll out, has adhesive near the seams which is easy to use, and you can easily cut this underlayment with a utility knife (be sure to have some extra blades). I’m using this on a concrete floor so the moisture barrier is required, nice to have it all in one step/product. My legs do not get as tired walking around on this floor, thanks to this underlayment. I used Gorilla tape for the outside edges and seam between rolls. Great stuff, I’m so happy with this purchase!
