GB/T 31433-2015General specification for building curtain walls, windows and doors (English PDF)

1 Scope

This standard specifies the performance classification and selection, requirements and tests of building curtain walls, doors and windows.

This standard applies to curtain walls, doors and windows, for civil buildings.

This standard does not apply to the external wall decoration systems, whose panels are directly pasted to the main structure AND the external wall dry hanging systems without supporting frame structures. It does not apply to special doors and windows, such as fire doors and windows, escape doors and windows, smoke exhaust windows, radiation shielding doors and windows.

The terms and definitions as defined in GB/T 5823 and GB/T 21086, as well as the following terms and definitions, apply to this document.

4 Performance classification and selection

The performance classification and selection of curtain walls, doors and windows shall meet the requirements of Table 1. standards.

5 Requirements

5.1.2 The design service life of main components, such as building curtain walls, door and window panels, profiles, etc. shall not be less than 25 years.

5.1.3 The fire and lightning protection requirements of the building curtain wall shall meet the requirements of GB 50016 and GB 50057.

5.1.4 The toughened glass used for building curtain walls shall meet the requirements of JG J102. The toughened glass used for doors and windows shall meet the requirements of GB 15763.4.

5.1.5 For exterior doors and windows with fire resistant integrity requirements, at least one layer of glass used shall meet the requirements of GB 15763.1. For the plastic exterior doors and windows, aluminum-plastic composite exterior doors and windows, steel-plastic co-extruded exterior doors and windows, aluminum-plastic co-extruded exterior doors and windows profiles, the reinforced steel or aluminum lining used shall be connected into a closed frame.

Meanwhile, it shall take measures, to prevent the glass from falling off, after being exposed to fire in the glass inlay slot.
