Typical applications use Sound Barrier applied to the wall, ceiling, or floor framing of a newly constructed room before the finished wall, ceiling, or floor is applied (roofing nails or fastener/washer recommended). 

For use in existing rooms, Sound Barrier is applied to the existing surface and then covered with layers of finish material (sheetrock, paneling, ceilings, flooring). For optimum performance it is recommended to separate material surface from one another using furring strips or resilient channels to further isolate vibration related transmissions.

At only 1/8" thick (1 lb Barriers), you can't beat Sound Barriers' reduction value!

Sound Barrier is available in either a non-reinforced version (for most uses) or a reinforced version (used when suspended vertically down from ceilings to prevent barrier from tearing under its' own weight)
