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.

XE – Non-reinforced sound 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.
MPME – Sound barriers reinforced with a high-strength polyester fabric are used to provide extra strength and durability to help prevent tearing when suspended vertically.
FSV Flexible sound reduction vinyl for ductwork and pipe lagging. It combines a loaded vinyl barrier with a reinforced aluminum foil facing on one side. It is designed to reduce noise that transmits through the walls of the pipe or duct as the content moves through it.
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.

Reinforced barriers are most commonly used in Noise Control Curtains or Blankets. The barrier is reinforced with high-strength polyester scrim fabric and used to provide extra strength and durability to help prevent tearing when suspended vertically.
Non-reinforced 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.
