Mass Loaded Vinyl Barrier MLVWhat is 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. SoundAway mass loaded vinyl barrier is available in one or two pound per square foot density, MLV 1# and MLV 2#, respectively. MLV 1# noise barrier is rated at 26 STC and the premium SoundAway Barrier Plus MLV 2# product is rated at 32 STC.

What is a soundproofing barrier?

Noise barrier or sound barrier products add mass to a wall, ceiling, floor, or enclosure serving as a highly effective soundproofing solution - at an affordable price. SoundAway soundproofing barriers are typically installed directly on the studs or joists to reduce noise transmission between the source of the sound and the destination.


What is STC?

Sound Transmission Class (STC) is a rating assigned to a material or an assembly of materials representing the transmission loss or reduction in sound between the source and the target. A standardized test, performed in an acoustics lab, measures the transmission loss between a Sound Source and a Target room. Measurements are taken over a range of 6 different frequencies ranging between 125Hz and 4000Hz. This frequency band covers the speech range. The table below lists the performance of our various mass loaded vinyl products with their corresponding STC rating.
