Advanced Low-Flow Passive Metal Sunshade & Minimal Airflow Ventilation Façade Panels

This advanced aluminum sunshade and ventilation panel system is specifically designed for high-performance building envelopes in commercial, institutional, and civic projects. The system features low-flow passive ventilation paired with perforated or louvered aluminum panels, acting as a secondary skin to reduce solar heat gain, improve thermal performance, and control glare.

By leveraging minimal airflow ventilated cavities, the design enables the stack effect to promote passive airflow without mechanical intervention. Perfect for both new construction and retrofits, this solution integrates acoustic, decorative, and safety functions—enhancing building energy performance, occupant comfort, and architectural expression（Product Attributes）
