Exterior Steel Frame Glass Door Construction
Glass Divided Lites
The lites on a door refer to the piece of glass that is framed and separated by lines that form divisions, also called mullions. The divisions of the lites can be true divided or simulated divided.
True Divided Lites(TDL): The glass on the door is multiple pieces instead of one single pane. These pieces are separated by larger mullions going through them.
Simulated Divided Lites (SDL): Simulating divided glass, this is a large, single pane of glass with the mullions laid on top.
True Divided Lites - TDL
- Easily replaceable due to the separation of all of the pieces. Offers easy cleaning and replacement.
- Due to mullions stabilizing the glass, this construction is stronger
- Mullion width: 1-5.8"
Simulated Divided Lites - SDL
- Most budget friendly
- Provides design similar to true divided
- Allows for mullions as small as 3/4"
