Zusammenfassung:	In roof window with a frame structure and an openable pane supporting sash structure, the top, bottom and side members (1-8) of the frame and sash structures are substantially made of wood profiles, which on the exterior sides are covered by covering members of the weather-shielding material. In respect of the top members (1, 5) the covering members comprise a hood-like covering cap (11) which is secured to the frame structure and covers the frame and sash top members (1, 5), and a ventilation passage (12) between an exterior opening (13) at a downwards facing edge member of said covering cap (12) and an interior opening (14) positioned at the interior side of the sash top member (5), said opening being in the closed position of the window closable by means of a ventilation flap (15) pivotally connected with the sash top member (5). To prevent convection current in the ventilation passage (12) and to obtain a ventilation with reduced loss of heat, the air flow area of the ventilation passage (12) is reduced to a substantially slit-shaped passage by means of an insert member (17). In this manner also an improved protection against intrusion is obtained. An additional insert member (18) may be connected with the interior side of the covering cap (12) to reduce the risk of condensation, when the ventilation flap is open. Dans une fenêtre de toit équipée d'un cadre principal et d'un panneau ouvrable supportant un châssis, les éléments supérieurs, inférieurs et latéraux (1-8) du cadre et du châssis adoptent pour la plupart la forme de profils en bois revêtus sur les côtés extérieurs d'un élément de matériau de protection contre les intempéries. Les éléments de revêtement comprennent une protection articulée (11) qui est fixée au cadre principal et recouvre le cadre et les éléments supérieurs du châssis (1, 5), ainsi qu'un passage d'aération (112) s'étendant entre une ouverture extérieure (13) ménagée au niveau d'un bord orienté vers le bas de ladite protection (11) et une ouverture intérieure (14) ménagée au niveau du côté intérieur de l'élément supérieur (5) du châssis. L'ouverture peut être fermée au moyen un volet d'aération (15) relié rotatif à l'élément supérieur (5) du châssis. La zone d'écoulement d'air du passage d'aération (12) est réduite à un passage en forme d'entaille à l'aide d'une pièce rapportée (17).
