QuietWalk is a premium recycled fiber underlayment built for luxury vinyl plank, luxury vinyl tile and multi-layer flooring like WPC, SPC, and rigid core vinyl planks. Suited for both floating and glue down installations either in residential and commercial applications. Impressive sound ratings (providing exceptional through-the-floor and footfall noise protection) make this underlayment the ideal underlayment to be installed under LVT, LVF, and MLF flooring. Provides additional comfort to the entire home during seasonal temperature changes. Recycled fibers allow installation over concrete to “breathe” – managing vapors from becoming bulk moisture. The attached vapor barrier protects the overlying floors from harmful moisture and alkalinity. Treated with anti-microbial to inhibit mold and mildew growth. STC rating of 62, IIC rating of 70 and Delta IIC of 28.
