Door
Door is a movable structure used to open and close off an entrance, typically consisting of a panel that swings on hinges or that slides or spins inside a space.
Construction and components[edit | edit source]
A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the portal of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. Doors are commonly made of wood or metal, but other materials such as glass are used.
Doorway[edit | edit source]
The doorway is the opening that a door closes. It is a passage through which one can enter a building, room, or vehicle. The size of the doorway must be enough to allow the passage of the largest object likely to need to pass through it.
Doorframe[edit | edit source]
The doorframe is the frame into which a door is fitted. The frame is usually made of wood or metal, and it is typically composed of two jambs, a header, and possibly a sill.
