Easy-to-Hang Sound Barrier Sheets

Suspend these thin sheets to reflect sound and block noise from traveling to other parts of your facility.

Gray and black vinyl fabric sheets are tear resistant.

Clear vinyl fabric sheets provide visibility so you can see and be seen. They’re often used as enclosure windows.

Vinyl-coated fiberglass sheets have a vinyl moisture barrier between the two outer layers.

Sheets with grommets on top edge are ready to hang and have hook-and-loop fasteners on the sides for joining multiple sheets together.
