SoundAway Barrier MLV 1# with PSA:
1/8" x 4.5' x 30'

SoundAway Barrier MLV PSA, wide roll, 1/8" x 4.5' x 30', greatly simplifies your installation process with a peel-and-stick pressure-sensitive-adhesive (PSA) backing on one side of your noise barrier. SoundAway Barrier MLV PSA is a dense, 1 pound per square foot, flexible, mass loaded vinyl soundproofing material designed to block and reflect sound.

Install two layers of SoundAway Barrier PSA perpendicular to each other, tape the seams using Lead Seam Tape, and apply Acoustic Caulk Sealant along the perimeter of the wall, ceiling, or floor surface to create an air-tight seal.
