When a fire door fails, the door itself is rarely the problem.
Across residential, healthcare, education and commercial projects, fire doors are often specified correctly. They meet the required fire rating, satisfy regulations and, on paper, appear fully compliant.
Yet when fire compartmentation is compromised, investigations frequently uncover a different issue: the hardware attached to the door.
The lock. The cylinder. The hinges. The closer. The letterplate.
Individually, they may seem like small decisions. Collectively, they can determine whether a fire door performs as intended when it matters most.
Most specification issues don’t arise because the wrong fire door was selected. They happen because hardware decisions are treated as an afterthought.
Common mistakes include:
Under project pressures, hardware can become a value-engineering exercise. Substitutions are made, components are swapped, and products are selected on availability rather than suitability.
The result can be a door set that no longer reflects the original specification intent.
Just because a lock, cylinder, closer or letterplate is certified individually doesn’t mean it has been considered as part of a complete door system.
Fire doors perform as assemblies, not collections of unrelated components. Hardware should be selected with compatibility and proven performance in mind.
Locks and cylinders are often viewed purely through a security lens.
In reality, they play an important role in the overall integrity of the door set. Choosing appropriately tested solutions, including Fullex locks and compatible cylinders, helps support both security requirements and wider fire door performance.
The components that receive the least attention are often the most overlooked.
Hinges, closers, seals and letterplates may not attract the same focus as major hardware items, but they are essential to how a fire door functions day after day and during a fire event.
Door closers, for example, play a critical role in ensuring a fire door returns safely and reliably to the closed position. A fire door that cannot close correctly cannot effectively compartmentalise fire and smoke. Appropriately tested closers, including those certified to EN1634 and suitable for timber fire doors with up to 60 minutes of fire resistance, help ensure the door assembly performs as intended when it matters most.
Letterplates are another often-overlooked component. Any aperture introduced into a fire door must be carefully considered to ensure the integrity of the doorset is maintained. Fire-tested and Certifire-approved letterplates for FD30 and FD60 timber doorsets help preserve fire performance, while providing the practical functionality required in residential settings.
Building occupants don’t experience risk in isolation, and hardware shouldn’t be specified that way.
A door set needs to provide security against unauthorised access, reliable everyday operation, and effective performance under fire conditions.
Solutions meeting recognised standards, including TS008-accredited letterplates that help prevent fishing and manipulation attacks, address security requirements, while appropriately tested fire door hardware supports life-safety performance. The strongest specifications are those that deliver both security and fire protection without compromise.
For years, the conversation has centred on selecting the right fire door.
The better question is whether we’ve specified the right door system.
Because a compliant fire door fitted with poorly considered hardware is no longer just a door. It’s a potential point of failure.
When fire doors don’t perform as expected, the cause is often not the door itself.
It’s the hardware decisions behind it.
