<p>The window (1) has a window sash (3), and a stop surface at which a middle seal lies under formation of room-sided and ventilation-sided folding chambers. An air flow control (25) limits an air-flow, and a blind frame profile (2) is designed as a hollow chamber profile with reinforcement and air-passage chambers. The air-passage chamber is divided into two partial areas separated from each other in a hermetically sealed manner, where one area serves for a room ventilation over the control and another area serves for independent room ventilation over a closed outlet opening.</p> |
