Fire Rating Door

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 and smoke between separate compartments of a structure and to enable safe egress from a building or structure

Fire doors are an important part of a building’s passive fire protection system, and doors in a means of egress provide life safety by allowing people to exit quickly when necessary. Still, the requirements remain a mystery for many architects and specifiers.



Simply put, an opening protective in a fire or smoke barrier is required to be a fire door assembly, which includes the door, frame, hardware, and glazing. These components are not typically required to be supplied by the same manufacturer—in most cases, they can be separate products which are listed, labeled, or classified for use in a fire door assembly. Occasionally, an assembly will be made of components that have been tested together and must be used to maintain the rating.





National Fire Protection Association (NFPA) 80, Standard for Fire Doors and Other Opening Protective, is referenced by the International Building Code (IBC), International Fire Code (IFC), NFPA 101, Life Safety Code, and other codes and standards. NFPA 105, Standard for the Installation of Smoke Door Assemblies and Other Opening Protective, addresses smoke doors.

Fire doors can help compartmentalize a building, prevent the spread of smoke and flames, and protect egress

routes to allow for safe escape. However, they must be properly specified, installed, and maintained to provide the necessary protection.
