A fire door is a door capable of meeting specific requirements for fire resistance-namely stability, integrity, and thermal insulation-for a defined period. It serves as a fire-resistant barrier installed in locations such as boundaries between fire compartments, evacuation stairwells, and vertical shafts.
In addition to the functions of a standard door, a fire door acts to prevent the spread of fire and smoke; it can contain the fire for a certain duration, thereby ensuring the safe evacuation of occupants.
