Difference between glass curtain wall and aluminum alloy doors and windows
[China Aluminum Industry Network] 1. Conceptual Differences Within a long period of time, the concept of curtain walls and doors and windows has not been unified within the industry. Both of them belong to the same building maintenance structure and do not share the burden of the main structure. The boundary practice has made qualitative windows and doors or curtain walls become difficult problems. Many companies often use door and window materials to design curtain wall effects in order to ensure appearance and consider cost savings. To a certain extent, they not only cause troubles for construction acceptance, but also The maintenance structure produced also laid a hidden danger for safety. In order to avoid the continuation of this kind of situation, the concept of the glass curtain wall is clearly defined in the “Technical Specification for Glass Curtain Wall Engineering†(JGJ102-2003). It consists of a support structure system and a panel, and can have a certain displacement capacity with respect to the main structure. The external maintenance structure or decorative line structure that does not share the role of the main structure.

Here is a point: relative to the main structure has a certain displacement ability. Doors and windows, as the maintenance components of the support in the main structural hole, cannot meet the ability of the relative main structure to have a certain displacement. In the curtain wall design, the entire frame is suspended on the outside of the main structure, and the relative displacement can be ensured by designing expansion joints and other structural measures.
Second, the difference between the standard specification The country introduced "aluminum alloy doors and windows" (GBT8478-2008) as a relatively new national standard doors and windows, each province, region, have their own provincial (land) standard. For example, the "Technical Specification for Aluminum Alloy Doors and Windows Engineering" (DGJ32/J07-2005) and the "Guidelines for the Design, Construction, and Acceptance of Aluminum Alloy Doors and Windows Engineering" (DBJ15-30-2002) in Guangdong Province meet the requirements in the design of aluminum doors and windows. Under the premise of national standard requirements, it is necessary to try to meet the requirements of provincial standards in various regions and ensure that local acceptance is satisfactory. “GBT7106-2008†is a relatively new national standard for the performance testing and grading of doors and windows. "Glass Curtain Wall Engineering Specifications" (JGJ102-2003) has long been recognized as a leader in the curtain wall industry standard, and the national standard "Building Curtain Wall" GB/T21086-2007 provides a more comprehensive exposition and agreement on the curtain wall system. The "Building Curtain Wall" (GB/T21086-2007) and "Test Method for Airtightness, Watertightness, and Wind Pressure Resistance of Building Curtain Walls" (GB/T15227-2007) provide the basis and method for the performance testing and rating of curtain wall projects.
