A transom is a horizontal structural element found in buildings, typically located above a door or window. It serves both functional and decorative purposes, allowing light and air to flow between spaces while also enhancing the architectural design. Transoms can be made of various materials, including wood, glass, or metal. In addition to their aesthetic appeal, transoms can improve ventilation and provide additional security. They are often seen in traditional architecture, such as Victorian or Georgian styles, but can also be incorporated into modern designs. Transoms are an important feature in both residential and commercial buildings.
