<p>Closure panel such as a window, a door, a wall, comprising on its contour a profiled frame (1b) which is mounted movable with respect to a profiled fixed frame (1a), for example a casing, against which it bears sealingly or is separated therefrom in an aeration position. In the latter position, there is arranged between the frames (1a and 1b) a space (17) defined by a flexible, sealing and/or noise damping and/or fire-proof material. In a cross-section view with respect to the two frames (1a and 1b), the aeration space (17) has a winding pass which comprises, at least in the minimum aeration position, between two sections (17a and 17e) open respectively towards one and the other faces of the frames (1a, 1b) and orientated in the opening direction (30) of the panel, at least one section (17c) orientated in the opposite direction.</p> |
