AlphaSorb® Fabric Wrapped Ceiling Banner

An AlphaSorb® Fabric Wrapped Ceiling Banner is a flexible banner that provides exceptional sound absorption with a fabric finish. These banners are designed to be used in facilities that require large amounts of absorption for sound and noise control. AlphaSorb® Ceiling Banners reduce reverberation (echo) time in harsh acoustical environments, while maintaining a very eye-pleasing look. They are designed to hang parallel to the ceiling via aluminum mounting stays and acceptable hardware.

AlphaSorb® Fabric Wrapped Banners are available in a standard width of 4 ft. (other custom widths available) and custom lengths up to 20 ft. Available in 2″ and 4″ thicknesses, the material is Class 1 fire-rated. AlphaSorb® Fabric Wrapped Banners are covered with a Guilford of Maine Fabric FR701, Style 2100. These banners offer easy installation, an attractive appearance and sound-absorption ratings from NRC 1.00 – 1.15.
