FAQs: HVAC Roof Curbs

Find quick answers about MicroMetl HVAC roof curbs, customization options, and product performance.

An HVAC roof curb is a structural component that provides a stable, elevated mounting platform for rooftop units and other equipment. It creates a secure interface between the building and the equipment while allowing for proper airflow and weatherproofing.

A roof curb is installed on the building roof and integrated into the roofing system to create a sealed, stable base. The rooftop unit is then mounted on top of the curb, with ductwork passing through the curb to connect the equipment to the building’s HVAC system.

Roof curbs are required for most rooftop HVAC installations to support equipment, ensure proper airflow alignment, and maintain a weather-tight seal. They are also critical in retrofit applications when replacing or upgrading existing rooftop units.

MicroMetl offers a wide range of roof curb solutions, including standard, knockdown, adjustable pitch, vibration isolation, seismic, and retrofit curbs, designed to match a variety of rooftop unit configurations and project requirements.

Roof curbs help ensure proper equipment fit and alignment, reduce the need for field modifications, and provide a secure, weather-tight installation. This supports reliable system operation and helps protect the building from water intrusion and installation issues.
