Texaa Strato ceiling
Description
Strato is a floating ceiling built from the Stereo family. Absorbing Stereo acoustic panels and open Stereo Air mesh panels hang on vertical cables and are joined so that the field stays flat and the joints even at any scale. Because it stays clear of the walls, Strato needs neither a perimeter grid nor stretch profiles. Opaque and open panels mix in any ratio to balance absorption against light and air, as one continuous field or as separate islands.
