What Is A Fire Rated Door

A fire-rated door is a door with a fire-resistance rating (sometimes referred to as a fire rating or fire door rating) used as part of a passive fire protection system to reduce the spread of fire and smoke between separate compartments of a building and to enable safe egress from a building or structure in the event of a fire.

In the United States fire-rated doors are classified by the time that they are able to withstand a standard fire test as determined by the Underwriters Laboratories (UL). The classification system is as follows:

-Class A: Doors that are able to withstand up to three hours of fire exposure.

-Class B: Doors that are able to withstand up to four hours of fire exposure.

-Class C: Doors that are able to withstand up to six hours of fire exposure.

-Class E: Doors that are able to withstand up to 12 hours of fire exposure.

-Class F: Doors that are able to withstand up to 16 hours of fire exposure.

Fire-rated doors are usually made of steel or reinforced gypsum board and are usually equipped with automatic closing devices such as fire-rated door closers that are activated by heat or smoke detectors.

Fire-rated doors are an important part of any building’s fire safety system and are required by code in many commercial and industrial applications.
