A » A mullion is a vertical architectural element that separates adjacent window units, providing structural support and stability. Often made from wood, aluminum, or steel, mullions help distribute loads and resist wind pressures, enhancing the strength and integrity of the window assembly. In addition to their functional role, mullions contribute aesthetically to the design of facades, creating rhythm and enhancing the visual appeal of buildings.
