Soundsulate™ PSA Mass Loaded Vinyl



Soundsulate™ PSA MLV (Mass Loaded Vinyl) is a multi-purpose sound blocking composite material with a peel and stick adhesive backing which helps to block noises. It is very effective in walls and floors and the very thin flexible characteristics makes it a great choice for a variety of sound control applications without compromising space.  It is designed to reduce noise transmission through floors, walls and ceilings. Typical applications include applying over studs, joists or suspended ceilings. It can also be used as an acoustic wrap for machinery, equipment and ductwork.

Soundsulate™ PSA MLV greatly simplifies your installation process with a pressure-sensitive-adhesive (PSA) backing. Once PSA MLV is installed, fasteners are strongly recommended to create a permanent hold.
