Curtain walling refers to a non-structural outer covering of a building’s facade that is designed to protect the interior from the elements. Unlike traditional walls, curtain walls are typically made of lightweight materials such as glass, aluminum, or steel, allowing them to span multiple floors. They are often used in modern architecture to create a visually appealing, transparent, and energy-efficient building envelope.
Curtain wall systems consist of a framework that supports the exterior cladding material, such as glass panels. The framing is attached to the building’s structure, but it does not carry the load of the building. Instead, the curtain wall transfers wind loads and its own weight to the building’s structure, making it an aesthetically pleasing and functional solution for large buildings with expansive glass exteriors.
