Can Aluminum Windows Be Used With Ventilated Facade Systems?

Yes—aluminum windows are ideally suited for ventilated (rainscreen) facade systems thanks to their lightweight strength and corrosion resistance. In a ventilated facade, metal panels are mounted on an external frame that creates a continuous air cavity behind the cladding. Aluminum windows are installed within that same sub-frame, with their frame flange integrated into the ventilated cavity. The window head, jambs, and sill are detailed to maintain the air gap: windows are backed by a moisture-resistant substrate or breather membrane, and weep holes or drainage channels in the window sill allow any infiltrated water to exit into the ventilated cavity. The cavity then promotes airflow behind the panels, rapidly drying any residual moisture and reducing thermal loads on the structure. For projects using aluminum ceilings under soffits or canopy edges, the ventilated system extends neatly into these soffit zones, with the same aluminum framing supporting both the overhead ceiling panels and window openings. This synergy between window and ventilated facade ensures long-term performance, enhanced indoor comfort, and a sleek architectural expression.
