What Is a Roof Curb?
A roof curb is a raised frame installed on a roof to support and connect rooftop equipment to the building. Curbs create a stable mounting surface for equipment such as air-handling units, exhaust fans, ventilators, and other mechanical components.
Proper roof curbing also helps coordinate the equipment opening with the roofing system. Selecting the correct curb dimensions, construction, and configuration is essential for supporting the equipment and simplifying field installation.
A mechanical roof curb may be specified for new equipment, while a curb adapter can help connect a replacement unit to an existing roof opening.
United Enertech Roof Curb and Rail Solutions
Conventional Curbs
United Enertech conventional curbs provide a dependable mounting base for rooftop mechanical equipment on standard commercial roofing systems. These curbs are available in multiple sizes and configurations to support a variety of equipment footprints and project requirements.
A conventional equipment curb can help streamline installation by providing a properly sized and coordinated transition between rooftop equipment, ductwork, and the roof structure.
Metal Building Curbs
Metal roofing systems require curbs designed to coordinate with their unique panel profiles and construction methods. United Enertech metal building curbs provide equipment support while fitting the requirements of pre-engineered metal buildings.
These rooftop curbs can be configured for different equipment types and roof conditions, helping contractors achieve a secure, compatible installation.
Conventional Rails
Conventional rails support equipment that requires an elevated or distributed mounting surface rather than a fully enclosed curb. A rail curb system can be used for condensers, piping, ductwork, and other mechanical components installed on conventional roofs.
United Enertech curb rails provide a practical way to support equipment while helping distribute loads across the rooftop structure.
Metal Building Rails
Metal building rails offer equipment support for standing-seam and other metal roofing applications. These roof curb rails are designed to coordinate with metal building construction while providing a strong mounting platform for rooftop mechanical systems.
A properly specified curb rail helps elevate equipment above the roof surface and provides the structural support required for reliable operation.
Curb Adapters
Replacing rooftop HVAC equipment does not always require replacing the existing curb. United Enertech curb adapters create a transition between an existing roof curb and new equipment with a different footprint or supply and return opening configuration.
Curb adapters can reduce modifications to the existing roof, simplify replacement projects, and help limit installation time. They are especially useful in retrofit applications where the new equipment does not match the original curb dimensions.
