Quiet walk is designed for floating laminate and wood flooring. QuietWalk’s recycled filaments are specially processed to cushion the floor, absorbing sound and reducing unwanted noise. This helps make floating floors sound more solid underfoot and helps to keep sound from traveling to other rooms. Although it can be installed over wood or concrete subfloors, QuietWalk is especially beneficial over concrete, where the exclusive Dri-Wick technology will effectively manage moisture vapor emissions that naturally occur in concrete slabs.Since QuietWalk and concrete are both “breathable” capillary products, vapors that are emitted will never accumulate under the pad into harmful moisture to the flooring. The Dri-Wick technology will wick away harmful water vapors while the attached vapor barrier protects the overlying flooring from any attacking moisture. With QuietWalk flooring underlayment you get better water protection, as the fibers manage harmful moisture concerns.
