Abstract (en)
[origin: EP0558469A2] A covering device (4) for windows (1) or the like consists of a secondary shell (5) which is arranged in the region of the window opening (2) and which has at least one hollow profiled box (6) forming an air-passage gap (7), the air-passage gap (7) being equipped with a sound-absorbing arrangement (8) consisting of an air duct (9) which preferably runs at an angle and of a sound-absorbing lining (10). In order to ensure, in addition to a great sound-insulation effect, adequate ventilation also, the longitudinally profiled box (6) has an air-passage gap (7) which extends essentially over the length of the profile and is flowed through transversely, the sound-absorbing arrangement (8) preferably comprising its own bass absorber (11) for absorbing sound at low frequencies. <IMAGE>
