Texaa Stereo wall and ceiling panel
Description
Stereo is Texaa's modular acoustic panel. A rustproof steel frame holds recycled white wadding behind a microporous cloth, dressed in a removable cover of knitted Aeria fabric. The frame keeps corners and edges precise in rectangular, round and triangular formats. In this version the panel sits flat on the wall or soffit and can be lifted off and refitted. Single panels treat a specific zone, while panels laid edge to edge form a continuous acoustic surface across a wall or ceiling. Panels in different colors vary a space discreetly. The same panel also exists suspended and as a partition.
