A standardized test performed in a certified independent soundproof lab measures the transmission loss between a sound source source and a target room target.
Stc of mass loaded vinyl.
Mass loaded vinyl can be an effective flexible and affordable product for soundproofing when used correctly.
Installing totalmass mass loaded vinyl barrier in a standard duty wall will decrease sound transmission.
For example mass loaded vinyl 2 is only inch thick.
While stacking drywall layers may get you to an stc 40 45 range mass loaded vinyl is a great option if stcs of 50 or higher are needed.
Stc rating of 26.
2lb mass loaded vinyl 1 4 thick and weighs 2 pound per square ft.
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.
Furthermore tms is of an inch thick weighs one pound per square foot and has an stc score of 27.
