Curtain walls are primarily considered to be what type of structure?

Curtain walls are primarily considered to be non-structural components of a building. They serve as the outer skin of a building and are designed to cover and protect the building from external elements such as weather and provide aesthetic appeal. Unlike load-bearing walls, which support the weight of the structure above them, curtain walls are not involved in bearing loads other than their own weight. Instead, they are typically attached to the building’s structural frame and allow for greater flexibility in design, such as large windows or open spaces. This distinction is crucial in understanding building design and construction, as it influences the choice of materials, engineering considerations, and overall safety during a fire or structural failure.
