doorways

Doorways are architectural openings that provide passage between spaces. They are defined by a frame embedded in a wall and are typically closed by a door. Beyond enabling movement, doorways serve privacy, security, and weather control, and influence light, ventilation, and acoustics in a building.

A doorway comprises the frame (jambs on sides, a head at the top), and often a lintel above to bear loads. A threshold sits at the base, and a door leaf is hung on hinges within the frame. Trims or architraves may surround the opening to conceal rough wall edges and to provide decoration.

Doors come in many configurations: hinged doors are standard; sliding doors run along tracks; pocket doors slide into the wall; revolving doors rotate on a central axis; pivot doors rotate on a pivot. Doorways can be rectangular or arched; some openings are decorative or monumental (portals).

Materials vary: timber frames and doors, metal frames and steel doors, or masonry openings with stone or brick. Weatherstripping, seals, and insulation affect energy performance. Hardware includes hinges, handles or levers, latches, and locks. Fire-rated doors provide restricted air and flame passage and are required in many buildings.

Historically, doorways mark transitions and status; grand portals in temples and palaces emphasize entry. In many cultures a threshold is seen as a liminal boundary.

Modern doorways must meet building codes and accessibility standards; minimum clear width for accessible doors is commonly around 32 inches (81 cm); safety and security concerns shape design choices.
