Only Armstrong products are designated as having Total Acoustics™ performance, the ideal combination of NRC (noise reduction) and CAC (sound blocking) in one ceiling panel. This makes it easier to specify one ceiling for an office space used for focus, collaboration, and privacy. This allows for flexibility in a space, where previously two different types of ceilings would have been specified for open and closed spaces. Armstrong Ceilings with Total Acoustics can help provide less intrusive noise and greater speech privacy to building occupants allowing for greater workplace satisfaction.
