Ventilation/smoke withdrawal flaps with an opener traverse are produced by a profile set of extruded light metal profiles comprises flaps (1,2,3), arch frame profiles (12,13) and opener traverse (18,19,20), insulating glass plates or plastic hollow chamber plates. Matching the plate thickness, a positioning member (4) is inserted in the grid openings (6) of the vane profile and a variable cylinder location is provided by the opener traverse. The inner light metal profiles (3,12) are connected with the outer light metal profiles (2,13) by insulating ribs (9) for interrupting the cold bridges.
