Product Info

Quiet Walk™ underlayment is the hallmark product of Midwest Padding. Although it was originally created specifically for laminate flooring, it now is also used under some nail-down and floating hardwood products.

Not only does it dampen ambient sound in the room it’s installed in, but it also inhibits sound from traveling into the room below. Although it is promoted as an upgrade underlayment taking the place of poly foam, it doesn’t carry a heavy upgrade price when compared to cork or rubber. On the other hand, in recent head-to-head Sound Transmission Loss tests, Quiet Walk™ outperformed both cork and rubber in the majority of test band frequencies. Certified field sound tests were performed on an installation over a standard concrete subfloor, and received an FIIC score of “60”.

In addition to it’s sound deadening benefits, the absorbing action of the synthetic fibers together with the attached vapor barrier provides superior moisture protection that is backed by a 15-year warranty.

Quiet Walk™ is available in 100 square foot do-it-yourself size rolls and 360 square foot contractor size rolls.

We don’t make laminate flooring, we make it quieter. Our new revolutionary "Quiet Walk" laminate floor underlayment smoothes out little subfloor imperfections while quieting impact sound and floor to ceiling noise. The protective covering resists moisture while our soft but firm pad adds cushion comfort under hard laminates.

Not only did ASTM testing of Quiet Walk score high marks for quieting laminate floors, but a side benefit is the increase in R-value to chilly floors. The 6’ x 60’ rolls of this 1/8th inch product make installation easy.

We don’t make carpet, we help it wear longer. Some lower grade carpet pads contain chemicals or compounds that "smell" and can also add to the aging process of a carpet or cause discoloration. Our padding has no Volatile Organic Compounds (VOCs), or Butylated Hydroxyl Toluene (BHTs), or resins that could harm carpet.

Midwest’s carpet padding is a premium cushion, ideal for residential or commercial applications. Each square yard of cushion contains millions of microscopic sized "springs" that assures resiliency and long term life for the cushion - and the carpet.

QuietWalk is ideally priced as a quality upgrade from polyethylene or polystyrene film and is less than 1/2 the cost of either cork or rubber underlayment with similar sound numbers.

Made from recycled materials.
QuietWalk is a "green" product, constructed (over 80%) with post industrial/pre-consumer fibers, materials that may otherwise have been landfilled.

Anti-Microbial Properties

  1. Synthetic fibers by their composition do not support the growth of bacteria and fungus.

  2. The high temperature manufacturing process used to produce QuietWalk will eliminate live organisms.

  3. Midwest Padding L.L.C. Incorporates an EPA registered anti-microbial in QuietWalk to control mold or bacteria on the treated product.

Sound Transmission Loss. The sound-insulating property of a partition element is expressed in terms of the sound transmission loss. ASTM E90-97, ASTM E413-87 Sound Transmission Class (STC) = 52.

Impact Sound Transmission. The method is designed to measure the impact sound transmission performance of a floor-ceiling assembly in a controlled laboratory environment. ASTM E492-90, ASTM E989-89 Impact Insulation Class (IIC) = 58.

Field Impact Insulation Class. Field conducted test using standard IIC methods. As tested over 8" post-tension concrete sub-floor with no ceiling assembly. (FIIC) = 60.

Moisture Absorption Approx. 650% by weight

Moisture Statement. Quiet Walk™ will absorb and allow dispersion throughout the product of water moisture in accumulations not exceeding one gallon per 24 hrs per 300 square feet of product and/or allowed to continue to accumulate for more than 7 days. Actual in-house tests have shown results up to 5 times that amount.


Features & Benefits          

Sound Absorption.
QuietWalk’s filaments are randomly air-laid creating a capillary affect to cushion the floor, absorb sound, and help make laminate floors sound more like real wood.

Sound Transmission Class (STC) = 52
Impact Insulation Class (IIC) = 58
Field Impact Insulation Class (F-IIC) = 60

Moisture Protection.
When installed properly, QuietWalk can wick sub-floor or incidental perimeter moisture and disperse it through the pad. Moderate amounts of moisture will eventually dissipate over time by perimeter or sub-floor evaporation, provided the source of water such as a leak is stopped.

Smoothes out minor sub-floor imperfections.
QuietWalk is firm enough (density=13.3lbs/ft^3; compression resistance @ 25%=9.5psi) to support the overlaying floor, but flexible enough to form around sub-floor surface roughness that may otherwise cause laminate panels to "rock" or lay unevenly.

Adds insulation value.
QuietWalk will add an R-Value of .50 to the floor system

Installation Instructions          
  1. Be sure the subfloor surface is clean and dry.
  2. Roll Quiet Walk underlayment over the subfloor with the vapor barrier film (logo imprinted side) facing up to allow the laminate flooring to slide easily over the surface.
  3. The perimeter edges of Quiet Walk 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 water and tear resistant, utility-grade, poly-coated cloth backed tape that has a very aggressive adhesive (duct tape).
  5. Install laminate flooring according to the manufacturer’s installation instructions.
