Fire Doors – What You Need To Know

What are Fire Doors? 

A fire door is a door with a fire-resistant rating which is used in passive fire protection systems to prevent fire and smoke spread between compartment and ensure a safe building escape.

What Qualifies as a Fire Door?

A fire door should comply with the requirements of BS 8214 with test evidence complying with either BS 476 or BS 1634-1, which will support the minimal requirements that fire doors must have at least three CE marked/Grade 13 hinges with a melting point above 800 degrees Celsius. Gaps between the door and frame should be between 2-4mm and the fire doors should be fully self-closing, engaging the latch into the keep every time, essentially closing the door on the fire.

Why are Fire Doors Important?

Fire doors are crucial for containing fire and smoke within a compartment to prevent the spread and ultimately protect life and property. In 2020, there were 64,066 primary fire incidents in dwellings and other buildings, increasing to 66,251 incidents in 2023. Following new regulations in January 2023, building owners must enhance their doors to comply with current fire safety standards, many building owners are unaware that this falls under their responsibility.

Different Types of Fire Doors Triangle Offer

  • FD30, Provides 30 minutes of fire resistance
  • FD60, Provides 60 minutes of fire resistance
  • FD90, Provides 90 minutes of fire resistance
  • FD120, Provides 120 minutes of fire resistance

FD30 doors are the most recommended type by fire safety standards as they provide a high protection and slow down the spread on fire along a route through compartmentalization.

Fire Door Requirements

  • Fire doors require intumescent seals to expand when exposed to heat, filling gaps between the door and frame to prevent smoke and fire spreading.
  • The gap between the door and the frame should be between 2-4mm.
  • Look for certification labelling, which confirms that the manufacturer belongs to an accredited and recognised third-party certification body. This indicates that the fire door has been produced in compliance with the safety standards listed above.
  • Fire doors should undergo periodic inspection per England’s Government Guidelines, which recommend inspections every six months, and more frequent for high traffic areas.
