Fire Door
 






Fire-rated doors are an extremely important part of a building’s overall passive fire protection system. A properly operating fire door and fire assembly is a key component in the compartmentalization of a building to stop the spread of deadly fire and smoke. The fire-resisted door assembly, which includes the frame and hardware, provides a specified degree of fire protection when the door is closed, and is composed of a surprisingly complex system of parts that allow the fire door to work properly in the event of a fire: the fire door, frame, fire exit hardware, door closers, hinges, locks, door bolts, and other door components.
