Model 638-CD | Combination Louver
Combination Louver
The 638-CD combination drainable and adjustable louver is designed to prevent water penetration in building exterior walls for non-wind-driven rain applications. Water is channeled away from the face of the louver via built-in drain gutters into vertical downspouts that allow the water to drain at the sloped sill. The louver utilizes a built-in adjustable control damper to allow for airflow shutoff for intake and exhaust applications. The 638-CD is an AMCA-certified louver.
