Faux Muntins & Mullions
In the past, mullions and muntins (or glazing bars in the UK) separated and held panes of glass in traditional multi-pane windows. After WWII, larger expanses glass with tempered were made available. Today, they're only used as a decorative feature in a few older homes.
Sometimes just a small or a single group of these wooden supports could be damaged by wind or rain leaving cracks in the window. The good part is that you can repair most of these rotting or brittle components.
