Quiet Floor NP is a high performance noise control barrier used as an underlayment when assembling a hardwood, ceramic, or carpeted floor. The grooved underside minimizes underlay contact between your finished flooring and the sub-floor. It reduces tile breakage. It also reduces impact noise and vibrations. It is available in ½” thick x 48” x 72” panels, to speed the application process.

MATERIAL: Recycled rubber.
PATTERN: Flat sanded face, performance engineered, diagonal grooves.
FEATURES: Grooved underside minimizes underlay contact between finished materials and sub-floor. Reduces ceramic tile breakage caused by cracking and fissuring of concrete slabs. Excellent floor to floor soundproofing.
APPLICATIONS: For use as a subfloor in new and renovation construction projects. Reduces impact noise and vibrations while reducing airborne sound transmission. Great under hardwood, ceramic or carpet. Can be used as finished floor.
THICKNESS: 1/2” SIZES: Nominal 4’ x 6’ WEIGHT: 65 lb.
COLOR: Black
THERMAL RESISTANCE: R 2/inch 100% vapor barrier
INSTALLATION: Use Mapei W55 adhesive to Adhere, the "groove side" of Quiet Floor to your sub floor. Allow 24-48 hours for adhesive to cure. It is recommended that another layer of marine grade or exterior grade plywood be adhered (with Mapei W55) to the “flat” or top side of the underlayment before installing the finish floor. In some installations, a finish floor can be adhered to the top of the Quiet Floor NP. Please consult a sales representative with specific installation questions.
