Custom Curved Metal Sunshade and Ventilation Panels for Complex Building Façade Geometry

Architectural Innovation Requires Façade Flexibility

Modern architecture embraces curves—elliptical atriums, convex auditorium shells, and double-curved museums demand non-linear façade solutions. Standard panels fall short.    Project-specific curved aluminum sunshade and wall ventilation panels solve the challenge by enabling airflow, light control, and structure-matching curvature in one integrated system.    Explore case: Spiral Theater Façade Retrofit

Parametric Geometry + CNC Panel Curving

Using Rhino + Grasshopper, designers model curvature-driven panel modules tailored to building radii. Data is exported for CNC roll-forming or stretch-bending of 3003-H14 or 5052-H32 aluminum sheets.    Profiles accommodate ≤6m radii with consistent airflow slots and blade pitch maintained throughout arcs. ISO 6308 bending tolerance and ASTM B209 material limits are observed.

Ventilation Behind the Curves

Behind the curved louver fins are micro-perforated vent panels enabling controlled cross-ventilation. Perforation patterns are calibrated using CFD airflow mapping, ensuring equal intake across convex/concave façades.    The Osaka Art Museum installed 1200m² of curved aluminum vent-shade panels. Interior temperature dropped by 5.3°C while airflow improved by 27.5%.    ASCE CFD Compliance Case

Surface Coatings and Glare-Free Finishes

All panels receive PVDF or anodized low-gloss coatings per ISO 2813, avoiding solar glare on compound curves. Acoustic backing can be added for auditoriums and amphitheaters using ASA-verified sound-absorbing mesh.

Installation Techniques on Irregular Geometry

Installation uses custom anchor grids with flexible bracket spacings. 3D-printed jigs ensure accurate arc replication onsite. Projects benefit from 30–50% fewer vertical joints compared to segmented panels.    In Abu Dhabi’s Media Dome, curved vent panels covered a 240° shell in 16 days, meeting Architectural Digest spotlight on complex geometry façades.
