These dense materials are used to block the transmission of airborne sound by providing mass to existing structures or hung as a limp mass partitions. Use these materials to soundproof walls, floors, and ceilings.
BlockAid® Vinyl Sound Barrier, also known as mass loaded vinyl (MLV), is a limp-mass material used to block unwanted noise and reduce sound transmission without reducing valuable room space.
BlockAid® Reinforced Vinyl Sound Barrier is a mass loaded vinyl (MLV) material to use when sound blocking is needed and a rugged and durable material is desired to construct a hanging limp mass partition.
Transparent Vinyl Sound Barrier is recommended where observation or supervision is desired. It is an excellent material to use over windows where sound blocking is needed, and it is desirable to retain the light coming through the windows.
Below is a tutorial on materials used to achieve excellent sound isolation. This video illustrates how multiple layers of different building materials, such as BlockAid® Vinyl Sound Barrier and fiberglass, are more effective than one single material at reducing sound transmission and increasing STC.
