SoundAway Barrier Plus-Wide, 1/4" x 4.5' x 15', offers the highest density, 2 pounds per square foot, and up to 33 STC in a dense, flexible, mass loaded vinyl soundproofing material designed to block and reflect sound.  Highly effective in blocking voices and reducing noise between floors.

Install a single layer of SoundAway Barrier Plus directly over your subfloor, tape the seams, and caulk around the perimeter to create an air-tight seal.  Leave no more than a 1/4" gap around the perimeter then fill the gap with SoundAway Acoustical Caulk.  Apply Lead Seam Tape to close the gaps between sheets of your noise barrier.
