7 Common Faults That Lead to Fire Door Failure

Fire Door test shows just how quickly a fire door failure will occur if incorrectly specified and installed

As part of Fire Door Safety Week (25 September – 1 October), the BWF-Certifire Scheme has released a dramatic video of a fire door burn test.

The video compares two almost identical fire doors with the same fire rating – FD30, meaning the door should provide at least 30 minutes of protection. This is the most common integrity rating for UK fire doors.

The video shows a fire door failure long before the 30 minutes it should last, highlighting the importance of correct fire door installation and maintenance. Without the protection of intumescent interlayer and intumescent seals, the faulty door allows smoke to pour through the gaps after just four and a half minutes.


Don’t make the same mistakes…

One door is correctly specified and installed, but the other has a series of faults which are frequently identified in social housing:

There are excessive gaps between the side of the door and the frame. (The gaps around the door should be less than 4mm once the door is shut).
The door has a non-fire rated letter plate. (Letter plates must be suitable for use on the specific fire door and detailed on the fire door certificate as a compatible component. Letter plates must also be fitted in the correct location within the fire door leaf and fitted with the correct intumescent protection and fixings).
Intumescent edge protection is missing around the glazing bead.
