Fan Curbs
Curbs for Fans and Ventilators
Fan curbs provide a stable, weather-resistant platform for mounting rooftop fans and ventilators. Just like our HVAC curbs, they’re available for flat, pitched, and metal or ribbed roofs—with or without insulation—so you get the right fit for every project. Depending on your application, fan curbs can be built as canted or self-flashing to meet structural and sealing requirements.
Curbco offers a full range of fan curb configurations to meet the specific needs of your project:
Pitched Fan Curbs – Designed to match roof slope for proper support and airflow.
Fan Curb Extensions – Add height to accommodate insulation or duct clearance requirements.
Pitch Correctors – Level the mounting surface on sloped roofs for optimal fan performance.
Directional Fan Curbs – Guide airflow in a specific direction to suit your application.
Fan Curbs for Metal Buildings – Built to fit structural ribbed or standing seam metal roofs.
Self-Flashing Fan Curbs – Provide built-in weather sealing for faster, cleaner installations.
Vibration Isolation Fan Curbs – Reduce mechanical vibration transfer for quieter operation.
Custom Fan Curbs – Built to your job-specific specs for a perfect fit every time.
