- Segmentation: Commercial buildings (such as super-high-rise office buildings) and public buildings (such as airports and hospitals) are the main application scenarios for curtain walls, with glass and aluminum as the two mainstream materials.
Technology Drivers
- Material Innovation:
- High-strength aluminum alloy (e.g., 6000/7000 series) replaces traditional steel, taking into account lightweight and load-bearing capacity.
- Composite materials (e.g., aluminum honeycomb panels) to improve thermal and acoustic insulation performance, to meet the needs of extreme climate.
- Energy-saving Technology:
- Ventilated curtain walls reduce air-conditioning energy consumption through heat exchange and have become the mainstream of the market.
- Smart glass (e.g., electrochromic glass) dynamically adjusts light transmittance to optimize the indoor environment.
- Digital Design:
- BIM technology runs through the whole process of design, production, and construction, improving efficiency and reducing errors.
- Parametric design supports the accurate landing of complex curved surfaces and shaped curtain walls.
Advantages of Aluminum Curtain Wall
- Lightweight: The density of aluminum alloy is only 2.7g/cm³, which significantly reduces the building load, especially suitable for high-rise and large-span structures (e.g., Shanghai Center Tower, Beijing Daxing Airport).
- Corrosion Resistance and Durability: The surface is anodized or fluorocarbon sprayed, with a weather resistance of 20-30 years, resisting acid rain, UV rays, and salt spray erosion.
- Recyclability: Aluminum recycling rate is over 90%, full life cycle carbon emissions are lower than steel, in line with green building standards.
- Design Flexibility: The extrusion process supports the customization of complex cross-sections, enabling artistic designs such as curved surfaces and openwork (e.g., Museum of the Future in Dubai, Ginza Plaza in Tokyo).

Technical Advantages
High-performance Insulation System
- Material Innovation: The use of broken-bridge aluminum alloy profiles with insulating glass, combined with thermal bridge blocking technology (e.g., multi-cavity insulation strip design) to effectively reduce heat transfer. Some system windows use recycled polyamide insulation strips, combining environmental protection and thermal insulation performance (thermal conductivity as low as 0.12W/m-K).
- Structural Design: By optimizing the frame structure and sealing process, the air leakage rate is reduced and the overall thermal insulation performance is improved. For example, the use of foam adhesive + nylon rib + EPDM composite adhesive strip ensures the stability of sealing under extreme climate.
Intelligent Curtain Wall Technology
- Integrated Function: Developing a hot-channel curtain wall system that combines double-glazing and intelligent ventilation facilities to optimize energy consumption in winter and summer. The thermal chimney effect is utilized to reduce air conditioning loads in summer, and the inner curtain wall surface temperature is raised in winter to reduce heating energy consumption.
- Monitoring and O&M: Deploying sensors and drone inspection technology to monitor the status of the curtain wall in real time (e.g., displacement, deformation), and combining with BIM modeling to carry out predictive maintenance to improve the efficiency of safety management and response.
Customized Service Capability
BIM Integration and 3D Modeling
- Full-process Collaboration: BIM tools such as Revit are used to realize the integration of design, processing, and construction, and support modular prefabrication and rapid on-site installation. For example, optimizing the construction of complex nodes through BIM parametric design ensures the accurate landing of curved, slanted, and other shaped curtain walls.
- Case Application: Providing a curtain wall solution combining ceramic panels and glass for the K11 ECOAST project in Shenzhen, optimizing the material layout and construction process through BIM simulation.
Rapid Prototyping
- Iterative Development: Shorten the design cycle by adopting the process of “low-fidelity prototype-user feedback-high-fidelity optimization.” 3D printing technology is utilized to produce node samples to verify structural strength and installation feasibility.
- Digital Pre-assembly: Virtual simulation to verify the joints and overall flatness of the unit panels, reducing the rework rate on site.
