SoundAway Carpet Underlay, 3/8" x 4.5' 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 high quailty
carpet underlay.
SoundAway Carpet Underlay greatly reduces impact sound as well as airborne noise. Simply install your Carpet Underlay directly over your sub floor 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.
