Model EV-345

Extruded Aluminum Louver
3" Deep - 45 Degree Vertical Blade

The EV-345 louver is engineered and tested to withstand extreme loads, debris impact, and cyclic fatigue associated with the severe weather effects of hurricanes. The design uses closely-spaced blades and a frame with built-in gutter and downspouts to achieve maximum water infiltration resistance for minimal louver depth, The EV-345 is tested in accordance with AMCA 540 and 550 making it ideally suited for use in hurricane-prone and windborne debris regions as per the International Building Code.
