Rails (9) and profiled bodies (8) at the bottom of the support members hold the edges of perforated ceiling panels (7). Air can circulate from the room (1) into a space under a horizontal membrane (5) with vertical fastening members (4) at the edges. A curved membrane (3) above the horizontal membrane defines a chamber (6).
