Is Your Door A Fire Door?
- Feb 28, 2019-
Older panel doors, especially if less then 44mm thick, are unlikely to be FD30. They could, however, have been upgraded or modified to achieve fire resisting standard. These days you might find certified paneled fire doors with wood surfaces to fit into traditional homes.
Hollow flush doors using egg box or similar construction will not be FD30. This can be detected by the weight of the door, because fire doors are much heavier than a hollow door. To check the weight of a door, instead of removing it, you can detach the self closer and swing the door between your thumb and index finger. This gives a good indication of the weight of the door. Hollow doors are reasonably easy to detect using this method.
Fire doors will have automatic closing devices (fire door closers) fitted. Spring-loaded self-closing hinges and concealed Perko door closers with chains might also be in evidence.
Because of the weight of a fire door and to prevent it warping, fire doors are usually fitted with three fire door hinges. The current BS EN standard does, however, allow two hinges in certain circumstances. There may be documentation that was supplied with a fire door giving you all the necessary information. Unfortunately, as there is no standard method of identifying fire doors other than the Q-Mark or the CERTIFIRE fire door schemes, insisting on written proof that a door meets all the necessary standards, for example a test certificate, might still be necessary.
