摘要

The door has a multi glazing (4) with two glass panels (6, 7), where the panels are provided and are separated by a gap (8). The gap is hermetically sealed. A volume-variable pressure equalization device (10) is linked with the gap, where the device has a form-changeable container (11). The device has a balloon whose inner space is brought in linkage with the gap. The device is integrated in a door frame, which is enclosed in the glazing.
