Lorsque l'extérieur est à une pression positive pendant des vents violents, la première plaque fonctionnelle 20 se rapproche de la première paroi principale 12a du fait de la pression du vent depuis l'extérieur, et la ventilation est assurée uniquement à travers la première garniture 25. Lorsque l'extérieur à une pression négative en cas de vents violents, la seconde plaque fonctionnelle 30 se rapproche de la seconde paroi principale 15a du fait de la pression du vent provenant de l'intérieur, et la ventilation est assurée uniquement à travers la deuxième garniture 35.
