Les persiennes empêchent-elles la pluie d'entrer?

Louvers are created to manage the flow of air into a structure while also offering a certain degree of protection against the weather. They have the potential to effectively prevent rain from entering, but this ability relies on various factors such as their design, angle, and spacing. To ensure that louvers fulfill their purpose of keeping rain out without hindering ventilation, it is crucial to carefully consider their design and orientation.
