A glass curtain wall is a non-structural building exterior—typically using lightweight aluminum frames to hold glass panels. Instead of supporting floor loads, it hangs from the building's structural frame, maximizing natural light, improving weather resistance, and offering sleek aesthetics for modern commercial and institutional buildings
Structure: They are independent of the building's load-bearing frame and span multiple stories.
Materials: Frames are usually extruded aluminum with thermal breaks for energy efficiency. Glass options range from tempered and laminated to insulated glass units (IGUs).
Spandrel Panels: Opaque areas used to conceal floor slabs, insulation, and mechanical services between floors.
Benefits: Provides excellent acoustic insulation, reduces dead building weight, and allows deep penetration of natural daylight.
