Curtain wall and window wall are both façade systems used in commercial buildings, apartments, hotels, and mixed-use projects, but their structural logic is different. A curtain wall is usually installed outside the building structure and spans multiple floors. A window wall is normally installed between floor slabs and is supported by each floor level.
According to the U.S. Department of Energy, windows and glazed openings can be responsible for about 25% to 30% of building heating and cooling energy use in residential applications. For façade projects, system selection affects insulation, water resistance, wind load performance, installation cost, and long-term maintenance.
| Item | Curtain Wall | Window Wall |
|---|---|---|
| Installation Position | Outside building structure | Between floor slabs |
| Building Height | Common for high-rise façades | Common for apartments |
| Appearance | More continuous glass façade | More segmented look |
| Cost | Usually higher | Usually more economical |
| Key Concern | Structural design and water drainage | Slab connection and sealing |
For curtain wall and window wall projects, a manufacturer gives better control than a trader. A manufacturer can manage profile design, extrusion selection, cutting accuracy, glass matching, gasket fitting, drainage structure, hardware assembly, surface coating, inspection, and packing. These details affect façade safety and installation efficiency.
HEKIN focuses on aluminum windows, aluminum doors, thermal break window systems, sliding doors, folding doors, casement doors, and curtain wall systems. For OEM ODM projects, HEKIN can support drawing review, custom size, frame color, glass configuration, hardware selection, packing design, and project quotation.
A façade project process usually includes drawing review, system selection, profile confirmation, glass specification, color approval, sample production, bulk fabrication, inspection, packing, and shipment. Wind load, water tightness, air tightness, thermal performance, acoustic performance, and local building code requirements should be confirmed before production.
Key checkpoints include profile wall thickness, corner strength, glass thickness, gasket continuity, drainage hole position, structural connection, coating quality, label accuracy, and export packing protection. For curtain walls, façade engineering review is especially important.
For export markets, buyers may review CE requirements, ASTM test methods, NFRC thermal performance data, AS/NZS requirements, and local façade regulations.
Curtain wall systems are suitable for projects that need continuous façades and stronger architectural impact. Window wall systems are suitable for projects that need practical installation, controlled cost, and floor-by-floor construction. HEKIN can support custom curtain wall systems and aluminum window wall solutions with manufacturing control and export-ready supply.
