A » A mullion is a vertical or horizontal structural element that divides adjacent window panes or panels. It provides support and stability to the window structure and can be made from various materials like wood, metal, or stone. Mullions create a grid-like pattern, enhancing the aesthetic appeal while allowing for individual window sections to be operable or fixed, thereby optimizing both design and functionality in architectural spaces.
