Drainable Louver - 4" Deep - 37-1/2 Degree Drainable Blade - FBC Approved - Extruded Aluminum - EFD-437-FL

Extruded Aluminum Louver
4" Deep - 37-1/2 Degree Drainable Blade

The EFD-437-FL louver is designed to prevent water penetration in non-wind-driven rain applications by collecting water in frame and blade gutters and channeling it into downspouts and away from airflow paths. The design is engineered and tested to withstand extreme loads, debris impact, and cyclic fatigue associated with the severe weather effects of hurricanes (Florida Building Code approval No. FL32498). The EFD-437-FL is AMCA 540 listed, making it ideally suited for use in hurricane-prone and windborne debris regions as per the International Building Code. In addition, the EFD-437-FL is a UL Classified Windstorm Rated Assembly with design pressures up to 250 psf (depending on section size).
