Fire Rated Door Info The door panel and the door frame must pass the guidelines of a testing agency that provides the product listing. The door frame is composed of the fire or smoke seals, door hardware, and the structure that holds the fire door in place.

Some portions of the door may be destroyed by combustion during exposure to fire; this is acceptable as long as the door assembly passes the fire test criteria of limiting temperature on the non-fire side of the assembly. The goal of the fire door is to slow down the spread of fire from one compartment to another for a limited amount of time enough for occupants to evacuate. Fire doors create a protected route to safety, assist the fire brigade and withstand the attack of fire for a limited time. Nonetheless, occupants are not always protected from smoke and fire by the fire doors. Poorly maintained and incorrectly installed fire doors pose a great risk to the occupants of the building and may result in fatal injuries.
