　　A transom window is a horizontal window positioned directly above a door or another window, traditionally used to admit daylight and ventilation while maintaining privacy and security. Historically common in schools, offices, and row houses, modern transom windows are celebrated for their ability to brighten interior spaces without compromising wall space or sightlines.

　　Fixed or operable, transom windows can be crafted from wood, aluminum, or vinyl frames with clear, frosted, or stained glass. Operable versions often feature crank or push mechanisms for airflow control. In energy-efficient designs, they incorporate double glazing and low-emissivity coatings to minimize heat loss while maximizing solar gain.

　　Architecturally, transom windows add rhythm, proportion, and historical charm to fa?ades. They are integral to styles like Art Deco, Craftsman, and Colonial Revival. Today, they bridge classic aesthetics with contemporary needs for daylighting and passive design—proving that this centuries-old element still holds relevance in sustainable architecture.
