Mass Loaded Vinyl Noise Barrier
Mass Loaded Vinyl (MLV) is a highly effective material renowned for its exceptional noise reduction capabilities. With its versatility, durability, and outstanding soundproofing properties, MLV has become the go-to choice for residential, commercial, and industrial applications.
What is Mass Loaded Vinyl?
Mass Loaded Vinyl (MLV) is a specialized material designed for noise reduction. It consists of a dense layer of vinyl embedded with minerals like barium sulfate or calcium carbonate. This unique composition gives MLV its impressive mass, allowing it to effectively block sound waves. Available in different thicknesses, weights, and sizes, MLV can be tailored to suit various noise control needs.
The industry standard MLV is 1/8″ thick, 1lb per square foot and has an STC Rating of 26. 1/2lb and 2lb psf options are also available at an STC rating of 21 and 31 respectively.
Standard vs. Reinforced Mass Loaded Vinyl
MLV is available in a standard and a reinforced option. The standard option is most often used in construction applications of walls and ceiling. The reinforced product is tear, UV, and weather resistant and is suitable for outdoor noise control applications such as Pickleball, Generators, and other outdoor mechanical equipment or construction.
