Why do you need them? A fire door is a door with a fire-resistance rating (sometimes referred to as a fire protection rating for closures) used as part of a passive fire protection system to reduce the spread of fire or smoke between compartments and to enable safe egress from a building or structure.
Both the door leaf (the swinging panel of the door) there and the door frame are required to meet the guidelines of the testing agency. The door frame includes the fire or smoke seals, door hardware, and the structure that holds the fire door assembly in place. Together, these components form an assembly, typically called a "doorset" which holds a numerical rating, quantified in hours of resistance to a test fire. All of the components of the fire door assembly must bear a listing agencies label (with the exception of ball bearing hinges which meet the basic build requirements of ANSI 156.2 and NFPA 80) to ensure the components have been tested to meet the fire rating requirements.
Door hardware includes, but is not limited to:
Automatic closing devices.
Ball bearing hinges.
Positive latching mechanism.
Edges of a fire door usually need to have fire rated seals which can be composed of:
An intumescent strip, which expands when exposed to heat
Neoprene weatherstripping
Gaskets to prevent the passage of smoke
When intumescent seals are used in the door design, use of the correct seal is crucial in the fire rating performance the door assembly. Seals may vary in chemical composition, expansion rate, expansion volume, and/or charring characteristics.
Windows (Vision Panels)
Some fire doors are equipped with internal windows which also have a rating, or have been incorporated at the time of the door test and be subject to the overall door's product certification. Fire-resistive windows must remain intact under fire conditions and hose stream impact resistance, and can include:
Wired, or clear Pyrodur glass.
