QuietWalk LV Acoustical Underlayment for Luxury Vinyl Flooring
QuietWalk LV is our most versatile premium underlayment, engineered to deliver firm support and exceptional acoustic performance for a wide range of hard surface flooring.
Designed with both sound control and moisture management in mind, QuietWalk LV features advanced DriWick technology—a unique blend of specialized recycled fibers that actively wick away subfloor moisture. An attached 6-mil vapor barrier provides a dual layer of protection, shielding your flooring from water damage and guarding the subfloor against spills and accidents from above.
What sets QuietWalk LV apart is its "self-healing" vapor barrier—designed to maintain moisture protection even when mechanically fastened during installation. Its adhesive-friendly surface also promotes superior bonding strength, making it the ideal solution for glue-down, floating, or nail-down flooring systems.
Recommended for use under:
- Luxury Vinyl Flooring (LVT or LVP)
- Enhanced Vinyl Flooring (WPC, SPC, Rigid Core, etc)
- Laminate Flooring
- Hardwood Flooring
Healthy Living!
Unlike many household products, QuietWalk LV is VOC-free and made without harmful chemicals—helping maintain cleaner indoor air and a healthier home environment for your family.
Ambient Sound Reduction (STC 62 – Sound Transmission Class)
QuietWalk LV is rated STC 62, meaning it effectively reduces airborne noise—such as voices, music, or television—before it travels through the floor and into the room below. A higher STC rating contributes to a quieter, more private living space.
Impact Sound Reduction (IIC 70 – Impact Insulation Class)
With an IIC rating of 70, QuietWalk LV significantly reduces impact sounds like footsteps, dropped items, and active play. This high-performance insulation makes it ideal for multi-level homes, apartments, or spaces where noise control is a priority.
Thermal Insulation & Comfort
QuietWalk LV adds an extra layer of thermal insulation, helping maintain indoor comfort during seasonal temperature changes. It’s also fully compatible with radiant heating systems, allowing warmth to distribute evenly through your floors.
Superior Flooring Support
- Dense recycled fiber core resists crushing and maintains its structure over time
- Properly supports click-lock flooring systems, enhancing stability and performance
- Creates a firm, hardwood-like feel under floating floors for a more premium finish
