Details:

Fire doors and frames play an important role in keeping people safe and minimizing property damage in the event of a fire. In fact, there has never been a person dying of a fire in a building where fire extinguishers were well installed and maintained.
Fire doors must meet the requirements of the International Fire Protection and International Buildings, as well as NFPA 80 Standard on Fireproof Doors and other door opening protection measures. Burning rates from 20 minutes to 3 hours. Hollow metal is the only spacious door material
available with 3-hour labels.
If the walls have a fire rating, then the frame and door must also have a fire rating. In the event of a fire, the heated door minimizes the transfer of heat to the fire-free side of the door so that people can safely exit the burning building. These doors are constructed with a specially designed core and are often found on the steps of a multi-story building.
