This flexible material also referred to as a limp mass barrier is made up of two principal components a natural high mass element such as barium sulfate or calcium carbonate and vinyl.

Stc of mass loaded vinyl.

A standardized test performed in a certified independent soundproof lab measures the transmission loss between a sound source source and a target room target. Best used in floors walls ceilings and outdoor fences. Stc rating of 26. However keep in mind that tms mass loaded vinyl is very heavy.

Best used in floors walls and ceilings. Our mass loaded vinyl is the highest quality vinyl barrier it is manufactured in the usa very heavy extruded from virgin material only and has no odor. For example mass loaded vinyl 2 is only inch thick. Mlv 1 is even thinner at 1 8 inch thick.
