QuietWalk LV is our most versatile premium underlayment choice allowing firm support for multiple types of flooring with great acoustic benefits. This product is built with sound reduction and moisture dissipation in mind. The unique DriWick technology relies on a blend of antimicrobial fibers that will wick away subfloor moisture, while the attached 6-mil vapor barrier is specially designed to protect your flooring from water damage. It has advanced "self-healing" properties that continue to protect from moisture, even if your flooring is mechanically fastened. The film is specially designed to offer superior bond with adhesives, making it the preferred choice for glue-down installation. Synthetic fiber underlayments are fast becoming the most specified product by architects and designers, due to their acoustical and moisture protection qualities. This recycled fiber underlayment will support and maintain the functionality of your flooring for a lifetime. A patented manufacturing process repurposes post-industrial and post-consumer materials into high-performance underlayment, giving you a unique eco-friendly option for flooring underlayment. QuietWalk LV underlayment can also be used with radiant heat systems such as QuietWarmth, for an extra warm and cozy floor.

Use with Luxury Vinyl, Laminate, and Wood Floors 4mm+ thick in floating, glue-down, or nail-down installation methods.
Recycled fibers absorb sound and keep it from traveling to other rooms, making click-together floating floors sound solid underfoot.
Dense intertwined structure supports the seams of your floor and won't compress under consistent foot traffic.
Unique Dri-Wick technology allows concrete subfloors to breathe, preventing moisture vapor emissions from becoming trapped, while anti-microbial fibers prevent mold and mildew growth.
Certified Clean and Safe Indoor Air Quality because QuietWalk LV emits no VOC's (Volatile Organic Compounds) or off-gassing from materials.
Pair with QuietWarmth Radiant Heat System for added comfort as QuietWalk allows heat to permeate evenly while helping to protect the floor covering material from thermal shock.
Made of Recycled Synthetic Fibers in the USA.
Approved for flooring with a pre-attached pad.
Most versatile underlayment option in the QuietWalk line of products.
