Abstract (en)
The present invention relates to a louvre (1), comprising at least two substantially horizontal, spaced-apart blades (2) which are arranged parallel to one another and which delimit an air flow duct (3) for air to flow through from an inlet opening (4) to an outlet opening (5), in which each blade (2) comprises an upwardly directed part (2a) adjacent to the inlet opening (4) and comprises a substantially flat or downwardly directed part (2b) adjacent to the outlet opening (5), and in which the watertightness is increased still further, substantially without affecting the ventilation capacity, by providing the air flow duct (3) with a sudden depression (D) between the upwardly directed part (2a) and the substantially flat or downwardly directed part (2b).
