Importance of Fire-rated Doors

Fire-rated doors help safeguard and secure your premises against potential fire hazards. They are specifically designed to slow down or help prevent the spread of fire and smoke. Fire-resistant doors are required by building code in any fire-rated partition and are needed to commission a building and to obtain insurance coverage:

  • Fire doors help slow or block the spread of flames and smoke.
  • Fire-rated doors are essential to comply with life safety standards and provide rescue teams the time needed to evacuate the building and safely fight any fire events.
  • Fire-rated doors help minimize the fire-related damage caused to the property and are an important component of your building's passive fire protection system.

Fire Door Ratings and Classified Openings

All the fire-rated doors must be self-closing, positive latching, and the frame and hardware must carry the appropriate fire label. The door you select will depend on the opening location and the wall it sits in. The site location is the primary factor in determining the requirement of the length of exposure based on the potential fire hazard. The table below is the opening classifications:

Door RatingWall RatingDescription
3 Hour (180 Minutes)4 Hour

These in-wall openings separate buildings or divide a single building into various fire areas.


1-1/2 Hour (90 Minutes)2 Hour

Often used in enclosures of vertical communication or egress through buildings, these types of openings include elevator shafts and stairwells. You can also expect them in boiler rooms or exterior walls with the potential for extreme fire exposure from the outside.


1 Hour (60 Minutes)1 Hour

The occupancies in a building are divided by these door and frame assemblies.


3/4 Hour (45 Minutes)1 Hour

These doors are used in a building with corridors or room partitions. They can be located in a building's exterior wall with the potential for moderate fire exposure from the outside.


1/3 Hour (20 Minutes)1 Hour

These openings are located in corridors requiring smoke and draft control.


*All the above fire-protection ratings are tested and classified by International Building Code.
