Sound Barrier Partitions

Two Partitions Shown

Set up these free-standing partitions to reflect sound and block noise from traveling to other parts of your facility. A vinyl barrier is sandwiched between two vinyl-coated fiberglass absorbers. Partitions have five grommets across the top for attaching to the frame; hook-and-loop fasteners on the sides join multiple partitions together.
