There are two types of divided lites: True Divided Lites (TDL) and Simulated Divided Lites (SDL). Doors with TDLs feature individual pieces of glass divided by muntin bars. They can utilize either single pane or double pane glass. Doors with SDLs are a single piece of double pane glass with bars applied to the glass surface. Many doors that utilize SDL Bars will also have a spacer bar in between for a more authentic look.
