What is a Transom Window?

A transom window is a rectangular, angled or fan-shaped horizontal accent window above or below another window or door. Since they are mainly added for appearance, they are very commonly seen about front doors or large windows on the front of the house. Transom windows are good for ventilation and for bringing additional light into a space as well as enhance the appearance of your home.

Window Transoms Add Architectural Style

After being utilized in certain spaces where a sophisticated shape or particular style door came together with another oblique architectural feature, transoms began to grow in popularity. They often serve as a conduit between a door and the eaves overhead.

Traditionally, transom windows are widely known as being shaped like a fan. They’re often beautifully showcased in custom Mediterranean style homes. Not only are they a visual feast to look at, but also let you see more of the beautiful scenery just outside.

Architects will generally tell you that transom windows are very purposeful in dividing the framing of a window from the framing of a door. While this is certainly true, they’re also works of art from a modern point of view.

Still, in most cases transom windows are primarily decorative. Transoms are often seen in Craftsman style homes. Structurally speaking, they’re not necessary. But, from a visual design perspective, they make the house a home and add to the overall ambiance of the space.

Bring Added Light into Your Home

One of the biggest benefits of transom windows is that they help bring added light into a space. This is particularly nice in a room that doesn’t have too many windows around the door. Transom windows add light to a dark entryway making it easier to see your door and the space around it during the day when you aren’t using interior lights.

Transom windows don’t just help bring light into a room above an exterior door, they can be used to transfer light from one of your exterior rooms, to one that’s farther into the interior of your home. Imagine that you have a room in your home with no exterior windows. Adding a couple transom windows to the walls of that room can create a sort of light bridge between the two rooms sharing their light and brightening them up substantially throughout the day.

Another major benefit of transom windows is allowing light into a space during times of the day when the sun is higher in the sky. When there isn’t as much direct sunlight coming into your home, a transom window can offer a solid source of light after other windows stop being useful. By extending your windows up higher you can enjoy a brighter room longer into the day.

Serve as an Architectural Accent

The most common reason that transom windows are used is for architectural accents. They are often fan-shaped, or given an unique angle shape to go along with the framed architecture around them. The windows serve to accent the door and add a bit of interest to exterior of your home. Architects make use of the windows when they want to break up a space, or effectively frame a door.

Added Ventilation

Most transoms are for decorative purposes, or to let light into a room, but they can also serve as ventilation when installed or modified properly. Standard transom windows don’t open or close, but there are some windows that serve like awning windows, meaning that they swing out and up. They create a mini canopy over the hole above your door and air can flow into the room. They’re good for letting in just a bit of air when you don’t want to open up all the other windows in the room, or for letting more airflow around a room that doesn’t have enough ventilation.

Many old plantation homes make use of transom windows to keep air moving and cooling the home throughout the day. High transoms are opened on the sunny side of the home to let hot air to escape, and low transoms are opened on the shady side of the home to let cool air in.

Not only do these windows allow ventilation throughout the day, they serve as a more secure form of ventilation when you’re not home. The windows are usually small enough or high enough that no one can climb into them, but they still let air flow in freely.

A transom window can really brighten up a space while giving it a distinguished traditional appearance. They make a huge difference when installed properly, just consider whether you want to use yours for ventilation or not before having it installed. The transom windows that open and close can be purchased and put in just as easily as the stationary windows, so it’s important to know whether you want a window that can open before ordering your window and having it installed.
