SoundAway Premium Barrier Carpet Underlay, wide Roll, 3/8" x 4' x 30', combines a layer of soundproofing barrier and a dense, sound-absorbing, and sound-blocking, closed cell foam.  This soundroofing composite decouples two rigid surfaces serving as an isolator, sound barrier,  sound absorber and a fabulous carpet underlay.

Install SoundAway Premium Barrier Carpte Underlay under the carpet in your home, car, boat, RV, or any other vehicle to significantly reduce noise.  SoundAway Barrier Mat resists moisture, mold, and mildew.

SoundAway Premium Barrier Carpet Underlay is an excellent carpet underlay that greatly reduces structure borne as well as airborne noise.  For home applications, install SoundAway Barrier Mat, as illustrated above, with the closed cell foam towards the floor.  Leave no more than a 1/4" gap around the perimeter.  Fill the gap with SoundAway Acoustical Caulk and tape the seams with Lead Seam Tape to create an air-tight seal.
