(57) A roof window, at least pivoting, has two sets of hinges situated at both side edges
of the window sash, preferably above the middle of the height of the sash, making
it possible to open the window pivotally, where the lower part of the sash moves outside
the roof, while the upper part of the sash to the inside of the attic. Centres of
mass of the elements of these hinges that mate with the sash are situated above the
external surface of the glazing unit (2), when the window is closed. The window frame
(3) is fixed to the roof structure through the support flashing (4). The window may
also have a second set of hinges situated near the top edge of the window, making
it possible to open the window either in the pivotal or tilting mode, i.e. by rotating
the whole window sash towards the outside of the roof.
