SonoFiber is now available in both one-inch-thick panels and two-inch-thick rolls. Panels come in a package of 14 units measuring 1 inch by 24 inches by 48 inches, and the rolls measure 2 inches by 48 inches by 300 inches [25 feet]. The rolls feature a black scrim membrane on one side. New colors for the panels are also available: charcoal, light gray, white, and beige. SonoFiber well suited for contractors and system integrators with projects requiring a Class A fire rating without the aesthetic demands of designer treatments such as fabric-covered panels. Made from recycled cotton fibers, SonoFiber is ideal for nightclubs, restaurants, gymnasiums, houses of worship, multipurpose rooms, and other commercial or industrial environments. SonoFiber is also ideal for unfinished metal deck ceilings with common acoustical issues like echo and reverberation.
