Four-leaf asymmetric vertical division 70-30 with a movable mullion

Four-leaf windows with asymmetric vertical division 70-30 with a movable mullion. Top wing 2/3 of the total height. Lower wing 1/3 of the height. The movable mullion is one of the elements of the window structure, permanently connected to one of the sash frames. This makes it possible to divide the window with the sashes closed, but after opening them, it allows free use of the non-divided space.
