Rain Defense

Louver rain defense is a measurement of how successful a louver is at keeping water from entering through a louver. Rain defense performance is measured by several test methods. AMCA Standard 500 water penetration tests use still air conditions.

Wind driven rain rejection tests by BSRIA, AMCA and HEVAC measure a louvers effectiveness under simulated rainfall and wind speed. Louvers in this search are organized from the most effective rain defense louver to the least.
