Curtain wall is a non-structural outer covering of a building, typically made of glass, aluminum, or other lightweight materials. It is designed to protect the interior from weather elements while enhancing aesthetics and energy efficiency. Unlike load-bearing walls, curtain walls transfer their weight to the building’s structural framework. These systems provide insulation, reduce energy costs, and improve natural lighting. Commonly used in modern commercial and high-rise buildings, curtain walls create sleek, contemporary exteriors while ensuring durability and functionality.
