A wind-driven louver is a specialized type of building louver designed specifically to prevent water from entering a structure during stormy weather.
Understanding Wind-Driven Louvers
While appearing similar to standard louvers, wind-driven rain louvers are designed to effectively prevent water penetration during storms. Their primary purpose is to keep water out, even when wind is actively driving rain against the building facade where the louver is installed.
Standard louvers, especially basic drainable models, are often sufficient for preventing water entry under typical conditions. However, high winds accompanying rain can force water horizontally or upwards, bypassing the drainage systems of conventional designs.
Why Use Wind-Driven Louvers?
When standard drainable louvers are not up to the task of blocking wind-driven rain, wind-driven rain louvers are engineered as the solution to keeping water out. They feature specialized blade shapes and configurations that create a tortuous path for incoming airflow, effectively separating and draining water droplets before they can penetrate deep into the louver assembly and enter the building.
Essentially, they offer a higher level of weather protection compared to standard options, making them critical for applications where keeping the interior dry during severe weather is paramount.
