What is a Fire Door ?
Definition of Fire Door in Construction The term fire door refers to the ability of a door to resist fire. A door that is fire resistant and carries a fire label can be tested as a one, to three hour door. There are special fire doors that are capable of resisting fire for over 3 hours, however, these are specialized doors and are normally custom designed and built. The fire door is a predetermined and tested assembly that has been subjected to rigid tests and inspections. These tests are regulated by a standard testing agency and will determine if the door can be rated and the extent of the rating. Fire doors are required wherever there is a code requirement for a fire rated door. Areas that typically require fire rated doors are garage to home, stairwells, electrical and mechanical rooms, special kitchen applications, etc.
