Create safer, more comfortable interior environments, ward off mold, insulation damage and other damaging effects of moisture — and keep condensation in check, too — with adjustable louvers from Metallic Products. The wall vent (or, as it’s better known in our industry, the wall louver) is designed specifically for pre-engineered metal building wall panels and offers a natural means of ensuring proper airflow into and out of your company’s metal buildings. Their roll-formed blades and plated twin-link pivot brackets make easy work of adjusting openings based on production needs, outdoor conditions and the like, all while keeping moisture and debris out. Meanwhile, their brass pivot bushings and durable build ensure smooth, noncorrosive and long-lasting operation.

The standard operator for our adjustable louver is the reinforced cast aluminum hand crank, but custom options are available. Your louver can be factory- or field-modified for chain operation or a motorized operator, something especially useful in instances where a hand crank is not accessible. The finished product features blade edge seals for maximum air sealing and 77% free area when opened to a full 90-degree angle. In addition, with a wide range of color and finish options available, your adjustable louver can suit your structure's unique aesthetic.

About Our Adjustable Louvers


18-gauge galvanized steel


20-gauge roll-formed galvanized steel


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.

Insect Screens

Aluminum screen cloth installed in an extruded removable, rewireable aluminum frame


Blade Operators

Twin-link brackets plated steel assembled with double brass pivot and set screw

Connecting Rod

Standard operator is by a reinforced cast aluminum hand crank. Optional: Chain operator of #35 sash chain, with plastic-coated chain pull handle

NOTE: Please specify panel type when ordering. The frame has a recessed head to accept the wall panel and side flanges fit specified panel profile on 1’ modules. The sill is tapered to provide drainage and exclude moisture. Flat flange louvers are also available for installation into framed openings.
