Article Summary: 

This article discusses the difference between muntins and mullions, two architectural elements found in windows. Muntins are vertical and horizontal elements that divide the window glass into a grid and are used for decorative purposes. Mullions are vertical shafts located in between windows that offer structural support to the windows. Traditional muntins were necessary to hold together small pieces of glass, while traditional mullions were made of stone and provided structural support and stability for windows or doors. Modern muntins are added for decorative purposes and are either resting on the exterior surface of the window glass or in between glass panes. Modern mullions are made of fibreglass, steel, aluminum, wood, or uPVC and are needed to provide support for window units placed side by side. The article discusses the practical and aesthetic benefits of muntins and mullions and their contribution to home security.
