Texaa Stereo suspended panel
Description
Here the Stereo panel hangs horizontally below the soffit on fine steel cables. The panel itself is unchanged: steel frame, recycled wadding, microporous cloth and a removable knitted Aeria cover, which can also wrap the top face where it stays visible. Panels float singly as clouds or hang on edge as baffles. Joined together, several panels form a flat cluster, the principle behind the Strato ceiling.
