Metallic Products’ adjustable louvers are built to ensure proper airflow into — and out of — your company’s metal buildings. Designed specifically for pre-engineered metal building wall panels, the adjustable louver features roll-formed blades with plated twin-link pivot brackets riveted to the blade and connected with ¼” zinc-plated rod. Its brass pivot bushings and durable build ensure smooth, noncorrosive and long-lasting operation.
The standard operator for our adjustable lovers is the reinforced cast aluminum hand crank. Custom options are available, however, and the louver can be factory- or field-modified for chain operation or a motorized operator. This is especially useful in instances where a hand crank is not accessible. Our operable louvers feature blade edge seals for maximum air sealing. They feature 77% free area when opened to a full 90-degree angle.

Louvers are self-mulling, self-flashing and self-framing. No other trim required. Louvers are chemically treated prior to painting. Louvers can be painted to match pre-selected colors by manufacturer. Standard paint is an electrostatically-applied powder paint, 3 mm thick with an oven-baked finish. After the paint process is completed, an extruded weather stripping is applied to the edge of each blade to ensure virtual air tightness in the closed position.
