Mass-loaded vinyl (MLV) is a heavy, flexible material used primarily for soundproofing. It is made by combining vinyl with heavy particles, which increases its density. This density helps block sound waves, making it an effective barrier against noise in various settings, such as homes, studios, and offices. MLV can be easily installed on walls, ceilings, and floors, providing a simple solution for reducing unwanted noise. It is often used in conjunction with other soundproofing materials, like acoustic panels and insulation, to enhance overall sound control. Its versatility and effectiveness make it a popular choice for both residential and commercial applications.
