How Long Do Fire Doors Keep Fire Out & How Long Do They Last?

Fire doors play an integral role in the event of a fire, serving as a life-saving shield that protects occupants and valuable assets. The life expectancy and effectiveness of these doors depend on several factors, including their maintenance and overall quality. But how long do fire doors last? In this article, we’ll go over some key aspects of fire doors, including their longevity and learning how long fire doors can keep fire out.

Fire Resistant Doors: The Role Fire Doors Play in The Event of a Fire


Fire doors are an important part of a building’s passive fire protection system. They are designed to inhibit, mitigate or slow down the spread of fire and smoke, thus providing occupants with more time to evacuate safely. Fire doors are usually installed in stairwells, corridors, and other compartments that form part of the escape route in a building.


By creating a barrier between the fire and the escape routes, fire doors help reduce property damage and can save lives. They are manufactured from various materials such as steel, vermiculite boards, and gypsum, each having distinct fire-resistant properties.


How Long Do Fire Doors Keep Fire Out?


The ability of a fire door to resist a fire is measured in terms of fire resistance rating. Fire doors are typically rated to withstand fire for 20, 30, 60, 90, or 120 minutes. The actual duration a fire door can hold back a fire depends on its rating, the intensity of the fire, and the material used in its construction.


A door with a 20-minute rating is designed to resist a fire for a minimum of 20 minutes, while a 120-minute fire door is designed to withstand a fire for up to 2 hours. The choice of a fire door’s rating depends on the specific building regulations and the nature of the building where the door is installed.


How Long Do Fire Doors Last?


The longevity of fire doors varies widely depending on factors like the quality of the materials used, how well they are installed, and how regularly they are inspected and maintained. On average, a well-maintained fire door should last around 10 to 20 years.


However, the lifespan can be drastically reduced if the door is exposed to heavy traffic, physical damage, or harsh environmental conditions. Regular maintenance and repairs, like replacing worn-out components and re-painting, can help prolong the life of a fire door.


Signs You Need a New Fire Door


Like any piece of equipment, fire doors can degrade over time and may eventually need replacing. A damaged or defective fire door is much less capable of holding back fires, which makes it incredibly dangerous to rely on. So make sure that the fire doors are regularly inspected for any sign of damage or wear and tear. Signs that you may need a new fire door include:


  • Visible damage like cracks, warping, or gaps around the door.
  • The door is difficult to open or close, or it does not close fully.
  • The door’s seals are worn out or missing.
  • The door’s fire rating label is not visible or missing.


Fire Door Inspection Frequency


Regular inspections are crucial to ensure that your fire door will perform as expected in the event of a fire. The Fire Protection Association (FPA) recommends that fire doors should be inspected at least twice a year, with higher traffic areas inspected more frequently. This inspection should cover all parts of the door, including hinges, seals, door closers, latches, and locks. Any defects should be fixed immediately to maintain the door’s integrity.
