Mass Loaded Vinyl

Mass Loaded Vinyl is used to reduce airborne sound transmission through walls, floors and ceilings. They are typically comprised of  a limp-mass material sound barrier made of high-temperature fused vinyl and no lead fillers.  With a typical weight of 1 lb. per square foot, these barriers are as heavy as lead, but only 1/8" thick. This improves the sound transmission loss (STC) of a construction assembly without loosing valuable space. It may be used in new and retrofit soundproofing construction. The standard offering is a non-reinforced barrier for use in typical construction. Other configurations include lag and wrap materials for pipes and ducting, a transparent version to allow line of site or light, a surface mount option and a reinforced version that may be suspended. These materials are often combined with other materials in soundproofing applications to help provide a complete sound blocking solution.
