Quiet Barrier™ Composite Install

The fiberglass composite is a really nice product, installed easily and does everything it is supposed to. We’ll be using them a lot more.

Composite was quick to install and started working immediately. Used it to go over top of a press in our manufacturing facility and has been a great help.
