SonoFiber is the perfect solution for those budget-conscious projects requiring class A fire rating without the aesthetic demands of designer treatments such as fabric-covered panels. SonoFiber is ideal for nightclubs, restaurants, gymnasiums, houses of Worship, multi-purpose rooms and any other commercial or industrial environment where aesthetic concerns are secondary to performance and safety. SonoFiber is 1-inch thick charcoal gray natural fiber acoustic absorptive panel that offers significant advantages over the more traditional class A melamine foam alternatives.
