BUTLER BUILDING HVAC CURBS

The Right HVAC Curb for Your Butler Building Roof Done Right the First Time

Butler HVAC Curbs provide a reliable, pre-engineered solution for mounting rooftop equipment on metal buildings. Designed for seamless integration with Butler roof systems, these curbs create a watertight, structurally sound base for HVAC units, exhaust fans, and mechanical equipment. Built for durability and precision, they simplify installation while protecting your roof from leaks and long-term damage.

Engineered Support for Rooftop Equipment

Mounting HVAC equipment directly onto a metal roof without proper support can lead to leaks, structural stress, and long-term maintenance issues. Butler HVAC Curbs solve this by providing a stable, elevated platform that integrates directly with your roof system.

These curbs are designed to distribute loads evenly while maintaining a weathertight seal around roof penetrations. The result is a cleaner installation, improved performance, and long-term protection for both your equipment and your building.

When a roof curb for HVAC is included with your order, flanges are customized to fit perfectly as possible and designed to carry certain point loads required for equipment placement. All curbs feature continuous seam welds. Side flanges nest with the roof panel, thus resulting in a completely watertight seal. Metal roof curbs come standard with 1″ foil-faced rigid insulation (R6.5). High R-values are available upon request. Our packages ship with all accessories for a complete curb install.
