Strato and Stereo are rigid sound absorbing panels faced with Texaa's signature acoustically transparent knit fabric, Aeria. Easy to clean and install Stereo panels are available in single units of 2'x4', 4'x4', 4'x8'. Strato is available in groupings of 4 or more interlocking panels. Stereo is ideal for ceilings or walls while Strato has been developed specifically for ceiling applications. Both products are framed in lightweight aluminum with all attachments and accessories available within the Texaa system. The implementation of Strato or Stereo panels on 30 to 40% of the ceiling surface is usually sufficient for excellent sound absorption.
