Easy-Assembly Stick Curtain Wall System with Integrated Multi-Layer Node Technology and Three-Dimensionally Adjustable Components

The stick curtain wall system operates on an on-site assembly principle, with individual components installed sequentially onto the building's primary structure. This methodology provides inherent flexibility for accommodating complex facade geometries and enables adjustments during and after installation. The system comprises vertical mullions, horizontal transoms, glass pressure plates, and associated connection components. All elements are manufactured off-site and delivered for assembly using bolted mechanical connections, eliminating concerns related to welding deformation. Mullions attach to the main structure through steel adapters offering three-dimensional adjustability, accommodating installation tolerances of up to ±20mm. Transoms feature closed-cavity profiles integrated with reinforced polyamide thermal breaks, establishing a continuous thermal barrier that maintains overall window U-values within 1.5 W/(m²·K).

The section assembly incorporates multiple performance layers: an external silicone weather seal provides flexible weatherproofing; intermediate EPDM gaskets create distinct air and water seals; and an internal pressure-equalized drainage network, formed by structural cavities and weep holes, manages moisture penetration. Glass configurations range from monolithic tempered panels to triple-glazed, dual-cavity ultra-low energy units, with provisions for on-site replacement or future upgrades. Exposed metal surfaces receive fluorocarbon coatings, while concealed connectors are protected via hot-dip galvanizing, ensuring system durability in corrosive environments rated up to C4.

This construction approach proves particularly advantageous for renovation work, irregular curved facades, and projects requiring staged installation sequencing. The inherent on-site adjustability allows installation parameters to be modified based on actual site measurements. Integration with BIM workflows facilitates digital component pre-assembly, enabling construction tolerance control within 2mm. Whether applied to heritage building retrofits, medium-scale commercial facades, or geometrically complex cultural venues, the stick curtain wall system delivers an adaptable, cost-effective, and sustainable building envelope solution through its methodically engineered nodal logic.
