Shipping Details

QuietWalk flooring underlayment is a premium choice for superior moisture protection, sound reduction, and subfloor support. Its advanced DriWick technology wicks away moisture, while the 6-mil vapor barrier protects against water damage. Made from recycled fibers, it enhances floor durability and comfort. Even if your flooring has a pre-attached pad, adding extra underlayment is crucial as most pre-attached pads lack a vapor barrier and only provide minimal sound absorption. QuietWalk ensures better acoustic performance, prevents moisture damage, and pairs well with radiant floor heating systems like QuietWarmth for energy-efficient warmth and long-lasting floor protection.

Use with Laminate and Floating Wood Floors including those with a pre-attached pad.
Extra Layer for Pre-Attached Pad Flooring – Most pre-attached pads lack moisture protection and sound reduction - adding QuietWalk underlayment improves acoustic performance and floor durability.
Best Sound Reduction Flooring Underlayment – Anti-microbial treated recycled fibers absorb sound, reducing noise transfer and making floating floors feel solid underfoot.
Durable Flooring Support – Dense fiber structure prevents floor movement and won’t compress under foot traffic, providing long-lasting subfloor support.
Moisture Barrier – DriWick technology allows concrete subfloors to breathe while the attached vapor barrier protects floors from moisture damage.
VOC-Free Flooring Underlayment – Certified clean with no VOCs (Volatile Organic Compounds) or off-gassing, ensuring healthy indoor air quality.
Eco-Friendly Flooring Underlayment – Manufactured using recycled synthetic fibers for sustainability, offering an environmentally conscious flooring solution.
Radiant Floor Heating Compatible – Pairs with QuietWarmth radiant heat system for even heat distribution and added floor protection.
Underlayment for Glue-Down and Luxury Vinyl Flooring – Choose QuietWalk Plus for glue-down laminate or wood flooring and QuietWalk LV for enhanced moisture protection and sound control with luxury vinyl flooring.

Oh my god this was easy to use. It laid down super easy and cut with some amount of difficulty, but it’s really helped even out the laminate flooring on top of it. The flooring underneath is uneven and it’s impossible to completely fix but it’s at least useable now.
