A passage (7) extends between the two profiles, the length side of which forms the passage entrance (8) on the outside (5) of the frame member (1), whilst the other length side forms the passage exit (9) on the inside (6) of the frame member, to allow ventilation air to pass through the frame. Independent claims are also included for (a) a frame member construction with a suction box (13) on the inside, whose entrance (14) overlaps with the passage exit, (b) a window frame member assembly method, by dividing a single-piece frame member into two extruded profiles, and (c) a window frame assembled from these frame members. Preferred Features: A window frame member comprises two extruded profiles (2, 3), the second of which defines the window opening (4) and is located between this opening and the first profile (2) secured to the wall. A passage extends between the two profiles, the length side of which forms the passage entrance on the outside of the frame member, whilst the other length side forms the passage exit on the inside of the frame member, to allow ventilation air to pass through the frame. |
