| 1 | Curtain Wall Product Classification | GB/T 21086-2007, Building Curtain Walls | Defines the principal technical performance categories for building curtain wall systems, including air permeability, water tightness, wind-load resistance and thermal performance. | Ability to provide system calculations, tested configurations, fabrication drawings and project-specific performance documentation. |
| 2 | Fire Protection Compliance | GB 55037-2022, General Code for Building Fire Protection and Prevention | Mandatory fire-safety requirements applicable to building design, construction, fire separation and fire-resisting interfaces. | Use of approved fire-stop assemblies, tested spandrel details, fire-resistant insulation and documented installation procedures. |
| 3 | Wind-Load Design | GB 50009-2012, Load Code for the Design of Building Structures | Provides the basis for determining wind actions and other design loads affecting high-rise façade panels, anchors, mullions and connections. | Project-specific wind calculations, structural modelling, corner-zone assessment and traceable connection design. |
| 4 | Seismic Performance | GB 50011-2010, Code for Seismic Design of Buildings | Establishes seismic design principles for building structures and components in different seismic intensity regions. | Movement allowance at brackets and joints, inter-story drift accommodation, anchor design and seismic testing where required. |
| 5 | Air Permeability and Water Tightness | GB/T 15227-2019, Test Method of Air Permeability, Watertightness, Wind Load Resistance Performance for Building Curtain Walls | Covers laboratory and performance testing procedures for air infiltration, water penetration and wind-load resistance. | Availability of full-scale mock-up testing, drainage design, pressure-equalized cavities and quality records for seals and gaskets. |
| 6 | Energy and Thermal Performance | GB 50189-2015, Design Standard for Energy Efficiency of Public Buildings | Addresses energy-efficiency design for public buildings, including envelope heat transfer, solar gains and glazing performance. | Thermal-bridge control, insulated framing, low-emissivity glazing options, condensation analysis and project energy calculations. |
| 7 | Safety Glazing | GB 15763.2-2005, Safety Glazing Part 2: Tempered Glass | Specifies requirements and test methods for tempered safety glass used in architectural applications. | Glass heat-soak requirements where specified, dimensional control, edge quality, breakage pattern and traceable inspection reports. |
| 8 | Insulating Glass Units | GB/T 11944-2012, Insulating Glass | Covers performance and testing requirements for insulating glass units used to improve thermal and acoustic properties. | Spacer selection, seal durability, gas filling control, cavity cleanliness, moisture resistance and production traceability. |
| 9 | Structural Silicone Glazing | GB 16776-2005, Structural Silicone Sealants for Building | Sets requirements for structural silicone sealants used in bonding and glazing applications in building envelopes. | Compatibility testing, adhesion testing, batch control, controlled factory application and documented curing conditions. |
| 10 | System Type and Installation Capability | Common high-rise delivery formats: unitized and stick-built curtain wall systems | Unitized systems are factory-assembled into panels; stick-built systems are assembled mainly on site. Selection depends on building geometry, programme, access and quality-control requirements. | Factory capacity, mock-up management, panel logistics, tolerance control, site supervision, installation safety and after-sales support. |
