Mass Loaded Vinyl Barrier MLV

Mass Loaded Vinyl (MLV) is a safe, non-toxic noise barrier designed to hang as a limp mass in a variety of soundproofing applications. MLV offers an alternative to Lead, at a lower price point. Mass loaded vinyl is available in one or two pound per square foot density - abbreviated as MLV 1# or MLV 2#, respectively.

Soundproofing systems combine mass, isolation, absorption, and damping to achieve the sound reduction results best suited for the application. MLV noise barrier adds mass in a minimal thickness. The MLV 1# is 1/8" thick. The MLV 2# is 1/4" thick. The MLV is typically embedded behind the finished walls, floor, or ceiling materials.

Sound Transmission Class

The industry standard unit of measure for a sound barrier material or wall, ceiling, or floor assembly is referred to as the Sound Transmission Class (STC). A standardized test, performed in a certified, independent, soundproof lab, measures the transmission loss between a sound source (Source) and a target room (Target). Measurements are taken over a range of 6 frequency points ranging from 125Hz to 4000Hz. The sound in the Source and Target rooms is measured. The difference between the two is the transmission loss.

The performance table summarizes the STC rating for the various MLV products.
