Soundsulate MLV is the superior solution over other soundproofing alternatives for blocking sound effectively. The very thin and flexible characteristics makes it an excellent choice for a variety of sound control applications without compromising space. It is designed to reduce transmission of airborne noises and vibrations 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. Please note: The thickness is nominal and may vary slightly due to manufacturing tolerances. Weight is the more accurate and consistent measure for performance.
