A muntin in U.S. use is a strip of wood or metal separating and holding panes of glass in a window. Muntins are also called "muntin bars '', "glazing bars '', or "sash bars ''. Muntins can be found in doors, windows and furniture, typically in western styles of architecture. Muntins divide a single window sash or casement into a grid system of small panes of glass, called "lights '' or "lites ''.
