Texaa Stereo partition panel
Description
Set on edge, the Stereo panel becomes a hanging partition. Either two stainless steel cables run through each panel from soffit to floor and are tensioned against concrete, so the panels hold their plane without feet or frames, or several panels hang one above another on thin cables from the ceiling, leaving the floor free. In large open spaces the partitions mark out sub-areas, separating them visually and giving each its own acoustic character without building walls.
