Window Muntins: What Are They?

Let’s start by exploring window muntins, which refer to the vertical dividers that separate glass panes in a window. Muntins are commonly associated with multi-pane glass assemblies, but they can also be found in other applications such as wood panels, furniture, and doors. These vertical pieces play a crucial role in providing structural support for the window. In fact, early builders used muntins because they were essential for distributing weight vertically, especially in the case of large windows like those found in Westminster Abbey.

Window Mullions: Explained

In contrast to muntins, window mullions are single vertical supports that divide two sides of a single window. They are typically heavier elements that help divide larger window frames and can create the illusion of multiple windows where only one exists. Mullions were commonly used to hold together smaller panes of glass before the advent of large sheets of plate glass. While mullions are no longer necessary for functionality in modern windows, they still serve a decorative purpose.

Grilles are decorative elements that mimic the look of muntins and mullions but are primarily used for aesthetic purposes. Stiles, on the other hand, are vertical or horizontal pieces that form the outer frame of a window. While these terms may seem confusing at first, they all contribute to the design and functionality of different window styles.
