Mullioned windows are windows which are divided into adjacent panes with the use of mullions, which are vertical elements used to break up a space. Mullions are especially associated with Gothic design, and some very fine examples of mullioned doors and windows can be seen in Gothic cathedrals and homes.arger mullioned windows may be used to illustrate a brief story or allegory, especially in church architecture. In this sense, the windows are more decorative than functional, since the stained glass obscures the flow of light into the building.
A window is an opening in a wall, door, roof or vehicle that allows the passage of light and, if not closed or sealed, air and sound. Modern windows are usually glazed or covered in some other transparent or translucent material. Windows are held in place by frames. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows often have a latch or similar mechanism to lock the window shut.
