AlphaFlex® Ripstop Ceiling Banner


Our AlphaFlex® Ripstop Ceiling Banner provides exceptional sound absorption with a durable, abuse resistant finish. These Banners are designed for facilities that require large amounts of sound absorption and acoustical treatment. AlphaFlex® Ceiling Banners reduce reverberation (echo) time in harsh acoustical environments.

They are designed to hang parallel to the ceiling via aluminum mounting stays or direct mount to the ceiling using washer plates and appropriate hardware. Especially effective and cost-efficient for large room environments. AlphaFlex® Ripstop Ceiling Banners are available in a standard width of 4 ft. (other custom widths available) and custom lengths up to 20 ft.
