Doors & windows

Doors, windows, and gates: the framed openings.

• DoorA hinged or sliding panel that closes a wall opening, hung in a frame fitted to both the opening and the door with fine clearances.
• WindowAn opening in a wall fitted with a frame holding one or more openable glazed sashes that let in light and air.
• GateA hinged frame set into a fence, wall or hedge, built like a light door but braced harder because one edge hangs unsupported on hinges.
