 Superior Sound Reduction

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

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

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

If you are looking for a test report please send an email to [email protected] and specify the product and type of report you are needing. We would be more than happy to email you a copy of any testing data that we have.

QuietWalk Plus is not approved for use with peel and stick vinyl flooring.

In theory, QuietWalk Plus would help to reduce the noise transfer in this application. However, we have not tested this particular application and cannot attest to the suitability. QuietWalk Plus is approved for use installed under laminate and wood flooring.

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.

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

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

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.
