What is the difference between a timber fire door and a steel fire door?
Timber fire doors are made from timber or composite cores, offering excellent fire resistance and aesthetic appeal. Steel fire doors, on the other hand, are made from galvanised steel, providing higher durability and impact resistance, and are often preferred for industrial or high traffic environments.

How long can a fire door resist fire? Fire doors are tested and rated by time. Typically FD30 (30 minutes), FD60 (60 minutes), FD90, or FD120. This indicates how long the door can withstand fire before failing. The actual rating depends on the door’s design, materials, and hardware used.
Do fire doors need to be kept closed at all times? Yes. Fire doors are designed to prevent the spread of fire and smoke by compartmentalising a building. They should always remain closed or be fitted with an automatic closing device that activates during a fire alarm.
What components make up a certified fire door set? A certified fire door set comprises the door leaf, frame, intumescent seals, hinges, fire-rated hardware (including handles, locks, and closers), and any glazing or vision panels. All components must be tested and approved to work together as part of a certified system.
How often should fire doors be surveyed or maintained? Fire doors should be surveyed at least every 6 months, or more frequently in high-traffic areas. Regular maintenance ensures that seals, hinges, and closers remain in complete working order and compliant with fire safety regulations.
What are intumescent strips, and why are they important?
Intumescent strips expand when exposed to heat, sealing the gap between the door and frame to stop smoke and flames from passing through. They are an essential safety feature and must never be painted over or removed.
Can I install a fire door myself? It’s strongly recommended that a qualified professional install fire doors. Incorrect installation can compromise the door’s fire rating and void certification. Always use certified installers.
Are fire doors required in all buildings? Fire doors are needed in most commercial, public and multi-residential buildings as part of fire compartmentation design.
How can I tell if my fire door is certified? Certified fire doors will have a label, plug, or tag (usually on the top edge or hinge side of the door) indicating the manufacturer, fire rating, and certification number. If either of these is missing, the door’s fire performance cannot be guaranteed.
