How does a curtain wall typically function in a building structure?

A curtain wall functions primarily as an aesthetic feature in a building structure. This means that its main purpose is to enhance the visual appeal of the building while allowing for large expanses of glass or other materials that contribute to a modern and sleek architectural style. Curtain walls are designed to be non-structural; they do not bear the weight of the building in the same way that load-bearing walls do. Instead, they are supported by the building's frame and serve to provide enclosures that can significantly influence the building's overall look and feel without adding structural loads.

While curtain walls can indeed contribute to performance characteristics like weather resistance, thermal efficiency, and sound control, their primary function is to offer a visually striking outer layer that complements the overall architectural design. The design allows for the incorporation of various materials, maximizes natural light, and often reflects the environment, providing a unique visual identity for the structure.
