The material flexibility of MLV is also well-suited for use in creating sound barriers and absorbing vibrations in motor vehicles-trucks, cars, buses, boats, campers, caravans, and RVs. The noise transmission from piping and HVAC ductwork can be reduced with MLV wraps, called limps, a loose wrapping application containing noise leakage. Noisy heat exchangers, generators, and pumps can also be quieted with MLV applications. MLV sheeting can be draped or hung on rods around heavy equipment and machinery in manufacturing and industrial environments, creating an acoustic blanket effect or sound screen curtain enclosure to dampen the noise. It can effectively shut out or substantially reduce the noise in busy apartment buildings, school rooms, mechanical rooms, partitioned spaces in office buildings, and so forth. Once installed between surfaces, even MLV with minimal thickness offers superior soundproofing. It can line ceilings, walls, flooring, and even doors and windows in commercial and public buildings and residential housing. MLV can be adapted for use on any surface that requires soundproofing. Such flexibility lends itself well to installation in a wide variety of applications, as the material can be hung, wrapped, or molded. MLV is a flexible material produced in standard widths of 4 or 4.5 feet in rolls up to a length of 100 feet or more, in thicknesses of 1/16, 1/8, and 1/4 inches. Most soundproofing materials are manufactured as thick or rigid panels, similar to hardboard, limited to specific design applications. MLV not only provides a potent barrier to sound but absorbs it as well.Īnother advantage is the material’s flexibility. Soundproofing is designed to prevent or reduce sound waves from entering an environment. Sound absorption dampens noise levels within a given environment, say, a recording studio. Most sound attenuating materials such as fiberglass, foams, and mineral fibers can only do one or the other. Once installed, MLV can effectively attenuate sound by blocking and absorbing sound waves. The addition of highly dense compounds to the vinyl provides the material with a natural high mass element that produces a soundproofing capability. As the name suggests, viscoelastic materials hold mechanical properties that combine a liquid high in viscosity with the elasticity of a solid material property resistant to permanent deformation. MLV consists of a viscoelastic material such as polyvinyl chloride or vinyl filled with highly dense inert compounds such as barium sulfate or calcium carbonate. It’s used in office and multi-dwelling residential spaces as well as single-family homes. The material helps reduce noise levels in construction and manufacturing environments or the sounds associated with buses, cars, trains, and aircraft. The lightweight yet dense membrane-like material effectively dampens sound and noise levels that occur in everyday encounters. MLV offers its users cost-effective solutions for a variety of noise-related issues. Commonly referred to by its acronym, MLV, mass-loaded vinyl is an acoustic material often installed during construction or remodeling where soundproofing is needed or required. Mass-loaded vinyl soundproofing is used in industrial, commercial, and residential environments to create sound barriers between walls, flooring, ceilings, partitions, and other surfaces.
