Jamb is a vertical architectural element that forms the side support or post of a door, window, fireplace, or other structural opening in a building. This fundamental architectural component, dating back to ancient construction methods, serves both functional and decorative purposes in architectural design. In its most basic form, a jamb provides essential structural support by transferring the load from the header or lintel above the opening to the foundation below, while also creating a clean, finished edge for the opening. The design and execution of jambs have evolved significantly throughout architectural history, from simple wooden posts in vernacular architecture to elaborately carved stone pieces in classical and gothic structures. In contemporary architecture and interior design, jambs continue to play a crucial role in both residential and commercial spaces, often incorporating modern materials such as aluminum, steel, or composite materials while maintaining their essential structural function. The aesthetic treatment of jambs can significantly influence the overall design character of a space, whether through minimalist contemporary approaches or ornate traditional styling. These elements are particularly important in sustainable and energy-efficient design, as they often house weather stripping and other insulation components that contribute to a building's thermal performance. The A' Design Award competition frequently recognizes innovative architectural projects where jamb design plays a crucial role in both functionality and aesthetic appeal, particularly in categories related to architectural design and building components.

Jamb is a term used in architecture and construction to refer to the vertical side member of a door frame or window frame. It is the fixed, vertical component that runs from the floor to the top of the frame, forming the sides of the opening. Jambs are crucial structural elements that support the weight of the door or window and provide a surface for hinges, locks, and other hardware to be attached. In door frames, there are two jambs, one on each side, while in window frames, there can be two or more jambs depending on the window's design. Jambs are typically made of wood, metal, or composite materials and are designed to seamlessly integrate with the surrounding wall, ensuring a secure and aesthetically pleasing installation. The term jamb can also refer to the similar vertical components found in fireplace openings and other architectural features. The proper installation and sealing of jambs are essential for maintaining the energy efficiency, security, and overall functionality of doors and windows in a building

Architectural historians and historians alike have long studied the concept of a jamb. In architecture, a jamb is the side or vertical surface of a doorway, window or fireplace. It is most commonly made of stone or brick, though it can also be composed of wood, plaster or other materials. Historically, the jamb served to support the architrave, lintel or cornice above the opening. It also provided a bearing surface to support the weight of the upper structure and, in some cases, to help prevent the opening from spreading. In some instances, it was also used to support a lintel or architrave, providing a decorative frame around the opening. During the Middle Ages, it was common for jamb stones to be decorated with carvings or inscriptions.
