NON-REINFORCED VINYL BARRIER
Non-reinforced vinyl barriers are suitable for non-abusive applications requiring low tensile strength. Typically used in a dry wall and stud construction to improve transmission loss between rooms.
REINFORCED VINYL BARRIER
Sound barriers reinforced with a high-strength polyester fabric are used to provide extra strength and durability to help prevent tearing when suspended vertically.
PIPE & DUCT LAG
Flexible sound reduction vinyl for duct-work and pipe lagging. It combines a loaded vinyl barrier with a reinforced aluminum foil facing on one side.
Acoustic composites are made up of open-cell polyurethane acoustic foam and mass- loaded vinyl barrier. Composites decouple the barrier from the noise source or structure and provide an absorptive layer where required.

Sound barriers are used to reduce the noise transmission between two spaces. It reflects sound back in the direction of its source. A typical application uses sound barrier applied to the wall, ceiling, or floor framing of a newly constructed room before the finished wall, ceiling, or floor is applied. For use in existing rooms, the sound barrier is applied to the existing surface and then covered with a layer of finishing material. For optimum performance, it is recommended to separate the material surfaces from one another using furring strips or resilient channels to further isolate vibration related transmissions. “KENNEDY” sound barriers are available in either a reinforced or non-reinforced version.
