Transom Windows

There are certain features of homes that are just as pleasant, attractive, and useful today as when they were first introduced into home construction years ago.

I strongly feel that ‘Transom Windows’ fall into this category.

A transom window is a window – typically rectangular or semi-circular – that is designed to sit directly above a door or other window.

Contrary to what some may realize, a transom window can absolutely be located above another window vs. a door, though many envision a transom window traditionally being located solely above doors.

A transom window can let in extra light and help with airflow.

Back in the day, before air conditioning, transom windows were especially useful for keeping a house cool because they could let hot air escape.

Today, they’re often used for style too, adding a nice touch to a doorway or room.

Transom windows can be both active (where they are able to be opened to help with air flow) or non-active (where they serve a purely decorative purpose).

Some of the more famous examples of transom windows are found in residential homes located in the historic brownstone buildings in places like New York City and Boston. These buildings often feature elegant entryways with transom windows above the doors, adding both charm and functionality.

Many older Victorian-style homes also incorporate transom windows above the main entrance or in other areas of the house.

Transom windows in these examples contribute to the overall architectural character of the homes and many would offer that they are key pieces to the overall architectural design elements, not necessarily meant to be the focal point, but providing that little extra ‘oomph’ which contributes to what in many cases are truly impressive designs to begin with.

Transom windows, though rooted in historical architecture, offer several benefits in modern homes as well, making them a popular design choice for both aesthetic and functional reasons.

As reviewed above, transom windows enhance natural light and ventilation. By placing them strategically above doors or other windows, they allow sunlight to penetrate deeper into the interior space, brightening up rooms that might otherwise be dimly lit. This natural light not only reduces the need for artificial lighting during the day but also creates a more open and inviting atmosphere. Moreover, transom windows can be opened to facilitate airflow, promoting cross-ventilation and helping to regulate indoor temperature and humidity levels – even in homes that have central air where allowing more natural air to occasionally circulate may be the desire of a more modern homeowner.

Transom windows contribute to energy efficiency. By harnessing natural light, homeowners can reduce their reliance on artificial lighting, thereby lowering electricity bills and environmental impact. When properly positioned and equipped with operable mechanisms, transom windows facilitate passive cooling and reduce the need for mechanical ventilation systems, further decreasing energy consumption and its associated costs.

Transom windows offer design versatility and aesthetic appeal. They come in various shapes, sizes, and styles, allowing homeowners to customize their appearance to complement the architectural style and interior decor of their homes.


Whether traditional or contemporary, transom windows can add visual interest, character, and charm to living spaces, serving as focal points or enhancing elements.

Transom windows provide privacy without sacrificing natural light. By positioning them higher up on walls, homeowners can maintain privacy while still benefiting from daylighting. Frosted or textured glass options offer additional privacy while diffusing sunlight, creating a softer, more diffused glow within the room.

Transom windows offer modern homeowners a combination of natural light, ventilation, energy efficiency, design flexibility, and privacy, making them a valuable addition to residential spaces. Whether renovating an older home or designing a new one, incorporating transom windows can enhance both the functionality and beauty of the living environment.

Both owners of older homes and those of more contemporary ones can benefit in various ways from this unique component of door and window design that is a feature which many may not ordinarily even think about when first delving into the way their home is designed or how it may be able to be improved.
