Transoms are a type of window located above a door, window, or other glazing materials. The most common type of transoms are those which are located above a door. Sizes of transoms mimic the size of the door. On a 36” wide door you will usually find a 36” transom that is 24” in height. A rule of thumb for a standard proportional transom height is to use one third of the door’s height. A large curtain wall can utilize a transom and will follow the bay divisions of the wall. At times, the transom can be cut to an arch shape for functional or aesthetic purposes.
A transom is typically fixed glass or operates like a hopper
window. A fixed transom has no operable parts. Its main
purpose is to let light into a room and provide
architectural appeal. An operable transom is hinged at the
bottom of the window. The transom will then open into a
room, preventing rain, wind, or snow from entering room
during inclement weather.
Often time’s transoms are adorned with grid work, especially
in traditional applications. When the building is in a
historic district or needs curb appeal, decorative items are
added. One of the most popular additions to a transom is a
Palladian arch. In this case a half round transom is
utilized and the exact number of radiuses is determined by
the client.
