Fenestration (Window and Door) Terminology
Fenestration terminology refers to the specialized language used to describe the various elements of windows, doors, and other openings in a building’s exterior. It includes terms related to the design, structure, and function of these elements, such as frame, sash, mullion, glazing, and jamb. Understanding fenestration terminology is essential for architects, builders, and designers to effectively communicate and ensure the proper selection, installation, and performance of windows and doors in both residential and commercial projects.
