You’ve probably heard about mullions and muntins when people talk about replacement windows. These two features are similar but they are also quite different from each other. More importantly, they can enhance your windows and your home’s exterior. Here’s a brief discussion on these two, straight from our window experts at Renewal by Andersen® of Central Illinois.
Mullions are vertical bars that go from the top edge of the frame to the bottom, dividing glass panes in the process. Mullions are usually made of the same material as the main edge of the frames. A window with mullions would have several vertical, rectangular glass panes instead of having one continuous pane.
Muntins are similar to mullions except they divide the window horizontally. A bay window will feature muntins to provide structural support to larger glass panes. Muntins are often seen with mullions (forming smaller rectangular panels), but unlike their vertical counterparts, they are rarely seen without them.
Better With Detail
One of the main purposes of mullions and muntins is to provide a layer of detail to the home’s exterior. Instead of a single continuous glass pane, the lines formed by both mullions and muntins make the home look more dynamic or intricate. This is why classic window designs favor windows with mullions and muntins and smaller glass panels over larger panels.
Stronger With Support
Mullions and muntins are also used for more functional purposes. As with the example made earlier with the bay window, larger window types have a better chance of resisting damage with both features supporting smaller individual panels. This also means damaged glass panels on double-hung windows can easily be replaced, since smaller glass panels are simpler to replace.
