Description
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. The standard vapor barrier is specially designed for optimal bond with adhesives for easy installation.
Product Features
- Use with hardwood flooring, glue and nail down flooring. Underlayment is for floating floor applications (Flooring that required no glue or nail down.) Will not work with 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
- Subfloor surface must be clean and dry before installation.
- Roll QuietWalk Plus underlayment over the subfloor with vapor barrier film (imprinted side) facing up.
- The perimeter edges of QuietWalk Plus underlayment need to be 1/2 to 3/4 inches away from the wall.
- 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.
- Install laminate/floating flooring according to the manufacturer's installation instructions.
Doubled Glue Down Floors
- Subfloor surface must be clean and dry before installation.
- Roll QuietWalk Plus underlayment over the subfloor with vapor barrier film (imprinted side) facing up.
- With a utility knife cut off the overhanging lip/flap before applying adhesive.
- Adhere to subfloor using recommended flooring manufacturer's adhesive and recommended trowel size and install method
- Roll over the underlayment with a 75 or 100 pound roller
- Adhere flooring over the top using manufacturer's recommended adhesive and trowel size
Nail and Staple Floors
- Subfloor surface must be clean and dry before installation.
- Roll QuietWalk Plus underlayment over the subfloor with vapor barrier film (imprinted side) facing up.
- Remove the tape strip from the edge and secure lip and tape edges together for proper moisture protection.
- Install flooring according to the flooring manufacturer's installation instructions and recommended fastening materials
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.
NOTE:
Due to the manufacturing process and the use of recycled materials, the pad thickness may vary .02 of an inch plus-or-minus. Actual weight of each roll may also vary 1.2 lbs. plus-or-minus. While it may appear that one roll is slightly larger than another, MP Global guarantee this slight variance DOES NOT affect the coverage area nor the sound absorption benefits of the product.
