Have you ever spotted a window atop a door? if yes, then you've seen a transom window. So, what are transom windows and what purpose do they serve? Read on to find out more.
What is a Transom Window?
Most of us have probably seen transom windows a countless number of times without knowing what they are. A transom window is a type of window that rests on the horizontal beam above a main door or window. They are usually small and rectangular in shape. These windows are named transom because they rest on top of a window's or door's transom. A transom is a structural beam that separates a door from a window above it.
The use of transom windows dates back to gothic times. From time immemorial, transom windows serve no structural purpose. They are installed for purely aesthetic reasons. Most transom windows are definite, many-sided, and fancy. People love transom windows because they expand their view and brighten up their rooms even though they are small.
In terms of design, most transom windows are fan-shaped. Some designs allow transom windows to be opened and closed while in other designs the windows are fixed.
The History of Transom Windows
Transom windows were first used in Europe in the 14 th Century. When they became popular during the gothic times, they were mainly used for ventilation purposes. In modern houses, they still serve the same purpose as seen in townhouses that lack central air.
Transom windows are popular in historical row houses. Row houses were attached to each other by the walls on one side. Row houses also had narrow floor plans with windows only at the front and back. These houses were designed for workers during the second industrial revolution in America. Their architectural design did not have a provision for air conditioning as they were long and narrow
Because row houses for workers lacked windows, transom windows stimulated airflow throughout the structures. They also allowed passage of air and light between rooms when the rooms were shut.
With the advent of air conditioning technology, the need for transom windows has become limited. The fashion of transom windows became outdated in the 1970s. In modern times transom windows are fixed, they do not open at all. These windows are only used for decorative purposes.
You will value transom windows because of their flexibility in design. Their height ranges from a few inches to a couple of feet. With this flexibility in design, transom windows offer a number of appealing possibilities.
What Purpose Do Transom Windows Serve?
Compared to interior transom windows, exterior transom windows are easy to install. Exterior transom windows are manufactured as one sealed unit to offer extra weather protection. Operable exterior transom windows are less operable thanks to insects and weather concerns. As a response to this concern, operable transom models are now motorized. They can be opened and closed through a mounted control panel. In fancy units you will find moisture sensors which automatically closes the window if it starts to rain.
Transom windows can be installed both on exterior and interior walls. Before air conditioning was invented, transom windows were opened and closed to allow for ventilation from outside to the inside and from room within the house. Even with a garden window installed, the door underneath can still be shut therefore retaining privacy and security.
Transom windows are installed in a way that they can be opened to a 30-degree angle. This angle allows for airflow without making the window hard to open or close.
If you are looking to buy a transom window you can choose from stock options in home improvement stores or you can have it custom made to suit your needs.

Custom transom windows are also expensive than stock transom windows.
Are Transom Windows Only Used on Exterior Doors and Windows?
From the time transom windows first appeared, they have not been restricted to exterior doors. In cases where transom windows are installed to serve a ventilation purpose, they are usually installed inside a building to help increase the airflow between buildings. They also increase the amount of light that reaches the inside rooms.
Modern transom windows not only increase the amount of light that penetrates inside but also make the rooms appear more open and bigger.
How Are Transom Windows Installed?
There are cases where transom windows are included in the original plans when a house is being constructed. As the home owner, you can request your architect to include the transoms in the plans or it may be his own idea to include them.
It is more complicated to add a transom window to an existing building. Remember it is difficult but not impossible. Engage the services of a structural engineer to help install the transom window. The structural engineer will cut away a section of the wall to create space for the window.
The last and more affordable option is to have the transom window installed as a part of a set with a door that includes a transom window in the frame.
How Do You Choose the Right Transom Window?
Like in any other purchase decision, the first step is to establish whether it is feasible to install the transom window either internally or externally. The second step is usually to consider how the transom will look. It is a proven fact that internal transom windows are suited for buildings with higher ceilings. Here, they give you that feeling of openness. These windows do not work well with homes with low ceilings.
After you've made the decision on which type to buy, guided by the two factors above, engage the services of a professional to have the window installed in the correct way. If not properly installed, transom windows can interfere with the structural integrity of your house.
Transom Window Installations- What You Should Know
Structure and style are two important factors that you should put into consideration before installing a transom window. The transom window to be installed has to suit your home structurally. High ceilings are more suitable for transom windows than standard ceilings.
Simple glass transoms are popular styles but you can still choose from a number of sophisticated leaded glass patterns.
Tips for Restoring Transom Windows
Transom windows that have been painted over can be restored to their former glory. This only requires the right tools and knowledge. If the window is made of one large piece of glass, remove the trim around the glass first then replace the old glass panel with a new one.
If the window is made up of multiple glass panels, first find out which glass panels need to be replaced. Remove the glass panels that you feel need replacement by prying away the glazing around that panel. Once you have replaced the panel, reapply the glazing material to hold it in place.
