Class A Fire Rating at an Affordable Price!

Auralex SonoFiber is the perfect solution for those budget-conscious projects requiring a 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’s flexibility makes it easy to install on irregular surfaces, and for filling cavities on corner-spanning panels. It is best used in overhead applications that are out-of-reach (not ceiling grids).
