Fire Doors Explained

Over the years many people have approached us asking us for clarification on fire doors, so we thought that lets make a blog on this to provide further clarification on fire doors.

What is a fire door?

A fire door is a door that has a fire resistant rating that is used to help reduce the spread of fire or smoke between areas. Fire doors are required to maintain a different fire rating level. When looking at sole occupancy units the rating required is 1 hour and looking a fire doors for common property areas the fire rating level required is 2 hours. Fire doors are essential and have known to inhibit fire and save numerous lives.

What is a fire resistance level?

Fire doors are required to have a fire resistance level this level lets you know how long the door is rated for with a fire for example a fire resistance level can be 120/120/60 this means the following:

  • Structural Adequacy: Meaning the wall will remain vertical and support the load for at least 120 minutes.
  • Integrity: The wall will inhibit flames passing through the wall for at least 120 minutes.
  • Insulation: The door will provide insulation so the other side of the door does not increase in temperature for at least 60 minutes.

Another example of a fire rating level is -/60/30. The dash represents that the structural adequacy is a non-load bearing door however the fire door provides integrity and insulation.

All fire door installations require the fire door to be fitted with a compliance tag to the fire door and door jam, this tag will display the following information:

  • Number of performance (Australian standard)
  • Fire Resistance Level
  • Year of Manufacture
  • Serial Number
  • Name of Manufacturer
