Window or sliding roof with window-panes with intervening cavity

摘要

The hollow cavity (2) between the two window panes is connected to at least one container (5) controlled by a drive unit and filled with liquid. The liquid can be conducted into the hollow cavity and emptied from it. Air in the hollow cavity can escape into an enclosed space, or via an outward pointing opening into the atmosphere. The openings (4) between the hollow cavity and the containers, and the air-escape opening (10) can be closed on the outside.
