How long do fire doors last?

Fire doors and their frames are usually tested to hold back fire for 20 minutes (FD30) to 180 minutes (FD60). Their ability to withstand fire is dependent on them being properly installed with the correct seals and fire rated hardware including fire door closers. The condition of a fire door, especially one that’s in regular use could deteriorate over time. Check your fire doors regularly and ensure any fire door maintenance is attended to promptly. Fire door inspections can help to identify non-compliant fire doors. Fire doors can have a rating greater than 60 minutes but these are not required in most situations.
