What is the difference between a glass curtain wall and aluminum alloy doors and windows?

【China Aluminum Network】 aluminum alloy doors and windows, refers to the use of aluminum alloy extruded profiles for the frame, concrete, fan materials, doors and windows made of aluminum alloy doors and windows, referred to as aluminum doors and windows. Including the use of aluminum alloy as a rod (to withstand and transfer the weight of the rod) substrate and wood, plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows.

The difference between concepts

For a long period of time, the concept of the curtain wall and doors and windows has not been unified within the industry. Both belong to the building maintenance structure and do not share the burden of the main structure. Certain boundary practices make qualitative windows or curtain walls become difficult problems. In order to ensure the appearance and consider the cost savings, many companies often use door and window materials to design curtain wall effects. To a certain extent, not only does construction inconvenience cause trouble, but the resulting maintenance structure also poses a hidden danger to safety. . In order to avoid the continuation of this kind of situation, the concept of the glass curtain wall is clearly defined in the “Standard Specification for Glass Curtain Wall Engineering”: it is composed of a supporting structural system and a panel, and has a certain displacement capacity relative to the main structure, and does not share the main structure. The structure of the external maintenance structure or the decorative line structure affected.

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.

The difference between the two standard specifications

The country launched "aluminum alloy doors and windows" (GBT8478-2008) as a relatively new national standard for doors and windows. Each province and region has its 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 curtain wall industry standards, and the national standard "Building Curtain Wall" (GB/T21086-2007) has more fully elaborated and agreed 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.
