The isolated product view keeps the sash arrangement and operating geometry clear before the room-fit and installation questions begin.
How it operates
The short answer
Many transoms are fixed; operable configurations and hardware vary and may be difficult to reach.
Common uses
- Daylight above doors
- Architectural combinations above larger window units
Ventilation, view, and daylight
- Only operable transoms provide ventilation; safe access to controls should be considered.
- The elevated position can add daylight while preserving wall or door function below.
Cleaning and maintenance
- Height and adjacent assemblies affect cleaning and service access.
Installation and performance considerations
- Combined-unit support, flashing, trim, glass safety, and access require a documented scope.
- Compare the complete combined assembly and applicable glass requirements.

Both may be fixed, but a transom is defined by its position above another opening or element.
