Our Best Selling Underlayment - QuietWalk Underlayment for Laminate, Hardwood Engineered, and Floating Floor Applications

Quiet Walk is a premium flooring underlayment choice allowing firm support for multiple types of flooring with great acoustic benefits. Built with sound reduction and moisture dissipation in mind.

Product Features

  • Use with laminate, floating engineered, floating bamboo and luxury vinyl plank (5mm and thicker). Underlayment is for floating floor applications (Flooring that required no glue or nail down.) Will not work with nail/staple or glue down applications or luxury vinyl flooring that is 4mm or thinner flooring.
  • Superior sound reduction recycled fibers absorbs sound and keep it from traveling to other rooms, makes click-together floating 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.
  • 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.
  • Delta IIC Sound Rating of 22. Delta rating is the best rating to consider when comparing the performance of different types of underlayment.
  • Moisture protection recycled fibers allow installation over concrete to & 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.
  • QuietWalk's compression resistance exceeds the requirement for pre-attached flooring that is greater than 29 psi @50% per ASTM D1667. The high compression resistance assures that the underlayment will not contribute to floor decoupling.
  • GreenGuard Gold Certified. Meets health based criteria for additional chemicals and also requires lower total VOC emissions levels to ensure that products are acceptable for use in environments such as schools and healthcare facilities.
  • Approved for in-floor radiant heat systems allows heat to permeate evenly while helping to protect the floor covering material from thermal shock, achieve warmth with quiet warmth radiant heat system
  • Easy installation - roll out and join the seam
  • Mold and Mildew Resistant
  • Made from Recycled Material in USA
  • Limited Lifetime Warranty
  • R-Value of 0.58. R-Value is a measure of the insulating ability of the underlayment.
  • Water Vapor Transmission Rate of 0.423 lbs / 1000 sq ft / 24 hrs. Result expresses the amount of moisture emissions the concrete emits using a calcium chloride test.
  • Use for both residential and commercial.

Info & Guides

Installation Instructions

Floating Floors

  1. Subfloor surface must be clean and dry before installation.
  2. Roll QuietWalk underlayment over the subfloor with vapor barrier film (imprinted side) facing up.
  3. The perimeter eges of QuietWalk underlayment need to be 1/2 to 3/4 inches away from the wall.
  4. Seams need to be butted together flush, do not overlap the pad. Tape the seams with duct tape, unless the roll is provided with a factory attached lip and tape system.
  5. Install laminate/floating flooring according to the manufacturer's installation instructions.

All wood and concrete subfloors must be flat within 1/8" over a 6' span, or 3/16" over a 10' span. All areas must be check prior to installation.

* In geographic areas where concrete slabs are subject to excessive moisture, a calcium chloride moisture test is required. Vapor emission readings in excess of 5 lbs. per 1000 square feet in 24 hours will require additional protection such as a concrete sealant or polyethylene sheeting.

Due to the manufacturing process and the use of recycled materials, the pad thickness may vary .02 of an inch plus-or-minus. Actual weigt of each roll may also vary 1.2 lbs. plus-or-minus. While it may appear that one roll is slightly larger than aother, MP Global guarantee this slight variance DOES NOT affect the coverage area nor the sound absorption benefits of the product.

    Unrolls nicely

    Posted by Luis R. on 9th Feb 2021

    The underlayment is nice thick material that is dense enough to roll out flat unlike other thin foams I have worked with.

    Would highly recommend

    Posted by Josh on 6th Jan 2021

    This underlayment has made my laminate floor sound very solid like real hardwood. This underlayment is great for the price!

    Love Felt!

    Posted by Simon on 3rd Dec 2020

    This is a great felt underlayment! It is very easy to install and the ends do not roll back up on you like most foams.

    Installed Upstairs

    Posted by John Henrickson on 23rd Sep 2020

    We recently updated our laminate flooring upstairs and decided to lay this underlayment down with it. Our kids bedrooms are upstairs while ours is on the main floor. The noise from their footsteps has been greatly reduced and there music does not travel downstairs as much.

    Sound Reduction is great

    Posted by John on 9th Sep 2020

    Overall easy to install, but make sure to have a sharp utility blade. Can be hard to cut otherwise. As for sound reduction compared to my friends laminate floors, mine are much more quiet when walking.

    Product Works Great

    Posted by Janice B. on 1st Sep 2020

    The product works great. The fact that you can tape them together with pre-attached tape is very handy! The quality is MUCH better than generic cheap underlayment!

    Good Quality

    Posted by Melanie on 30th Jun 2020

    This underlayment has some weight to it! I could tell it was a quality material right when I pulled it out of the box. Performs exactly how it's advertised. Make sure to have a sharp utility knife when cutting though.

    Excellent sound absorption

    Posted by Jessica on 16th Jun 2020

    I had this installed in my living room under my new laminate floors. My old laminate floors did not have underlayment and the noise difference is huge! I would recommend this for anyone who is installing new laminate flooring!
