The present disclosure relates to a roof window (1) for installation in a roof structure of a building. The roof window (1) comprises: a frame arrangement (2) comprising structural elongated frame profiles (2a-2d) that encloses a frame opening (FO), and the frame profiles (2a-2d) each comprises a first exterior side (ES1) facing the frame opening (FO) and a second exterior side (ES2) facing away from the frame opening (FO). Also, the roof window comprises one or more holding members (9) comprising a holding part (9a), a wall part (9c), and a fixation part (9b), Additionally, the roof window comprises an insulating glass unit (3) comprising at least a first glass sheet (3a) and a second glass sheet (3b). An insulating gap (4a) is provided between a major surfaces (3a1, 3b2) of the glass sheets (3a, 3b) and the insulating gap (4a) is sealed by means of an edge seal (6) arranged between said major surfaces. A side portion (8) of the major surface (3b2) of the second glass sheet (3b) extends with a distance (DIS1) past a part (6e) of the edge seal (6) that faces away from the insulating gap (4a) so as to provide a space (10) opposite to said side portion (8). The wall part (9c) overlaps a side edge (7b) of the second glass sheet (3b), and the fixation part (9b) overlaps the second exterior side (ES2) of the overlapped frame profile (2a-2d) and is attached to the overlapped frame profile (2a-2d) at the second exterior side (ES2). The holding part (9a) extends (9) into the space (10) and provides a holding force towards the side portion (8) so as to secure the insulating glass unit (3) at the frame arrangement (2).
