A Polywrap sound baffle is an economical and efficient way to solve industrial noise control problems. These acoustic baffles are comprised of heat sealed polyethylene bags and contain sound absorptive fiberglass. The baffles are available in a standard size of 4’x 2′. On each baffle there are two grommets on the 4′ side. These grommets will allow you to suspend the acoustic baffles from wire or cable ties. These baffles are lightweight and Class A fire rated. You should use these baffles in areas where you want to introduce noise control into hard, reflective environments. Reflective environments can exist in numerous applications, such as woodworking facilities, industrial plants, gymnasiums, environmental control booths and tone rooms.
