Proper ventilation is one of the most critical and most overlooked components of any commercial or industrial steel building. Without it hot air builds up in summer, condensation forms in winter, and the result is rust, mold, deteriorated insulation and costly product damage inside your facility. Butler Building Wall Louver Vents solve all of that. Located at the high peak or wall of your Butler building they create a natural airflow path that keeps your building interior comfortable, dry and protected year-round.  Wildlife Urban Interface vents also available with special order.

Create safer, more comfortable interior environments, ward off mold and insulation damage — and keep condensation in check, too — with adjustable louvers from Metallic Products. Designed specifically for pre-engineered metal building wall panels, our wall louvers are a natural means of facilitating airflow for your metal buildings.

Self-mulling and self-flashing, our adjustable wall louvers fit into your metal building panels with no additional hardware required and can be mulled together to form a continuous run. Roll-formed blades and plated twin-link pivot brackets make it easy to adjust airflow based on output, environmental conditions and the like while keeping moisture and debris out.

The standard operator is the reinforced cast aluminum hand crank, but custom options are available. Adjustable louvers can be factory- or field-modified for chain operation or a motorized operator. 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 blend seamlessly into your aesthetic.

Adjustable wall louvers are designed to integrate with Butler metal wall assemblies while supporting airflow management and weather performance. Available frame options allow compatibility with various wall conditions and installation requirements, including self flashing metal building flanges designed to integrate with metal wall panels.

By coordinating ventilation components within the overall wall system, Butler buildings can support efficient airflow management without compromising structural reliability or long term building performance.
