A fire-rated wood door is a timber-faced leaf with a solid, fire-resisting core, hung in a timber frame and tested with its seals, glazing and hardware to hold back fire and smoke for a set time. In British practice these doors are often described as FD30 or FD60, meaning 30 or 60 minutes in a furnace test to BS 476-22. Under EN 1634-1 the same idea is classified with letters and minutes, for example EI 30 or EI 60. As with all fire rated doors, the rating belongs to the complete assembly, not to the leaf on its own.

Timber fire doors are chosen where appearance matters as much as separation: hotel corridors, office floors, apartment entrances, hospital wards and classrooms. A veneered, laminated or painted leaf can match the joinery around it while meeting the rating set by the fire strategy. On most projects they sit in the same door schedule as steel fire doors, security doors and emergency exit doors, and each opening should be matched to the rating its wall requires.

Timber is not the right answer everywhere. In stair cores, plant rooms, car parks and loading areas, where impact and trolleys are constant, a steel fire door will last longer. Timber doors are also more sensitive to humidity and to how they are stored on site. They should be kept flat, dry and off the floor, delivered close to installation, and hung within the gap tolerances given by the manufacturer.

Key benefits

  • A finish that suits the interior

    Veneer, high-pressure laminate or paint finishes let a fire door match the surrounding joinery in hotels, offices and residences.

  • Rated as a complete door set

    Leaf, frame, intumescent seals, glazing and hardware are specified together, so the installed door matches the construction that was tested.

  • Solid fire-resisting core

    A solid core, rather than a hollow one, gives the leaf its fire resistance and a firm, quiet feel in daily use.

  • Seals at the edges

    Intumescent strips expand in heat to close the gap between leaf and frame, and smoke seals limit cold smoke before that happens.

  • Protected edges

    Hardwood lippings on the leaf edges take the knocks of everyday use and give a durable edge for seals and hardware.

Frequently asked questions

What is the difference between FD30, FD60 and EI 30?

FD30 and FD60 come from British testing to BS 476-22 and mean the door kept its integrity for 30 or 60 minutes. A suffix S, as in FD30S, means the door also has smoke seals. EN 1634-1 results are classified with letters: E for integrity and I for insulation, so EI 30 means 30 minutes of both. The rating you need comes from the building's fire strategy.

Should we choose a wood or a steel fire door?

Both are available in common ratings such as 30 and 60 minutes, so the choice is about use and appearance. Timber suits hotels, offices, residential corridors and wards, where finish matters and traffic is moderate. Steel is better in stair cores, plant rooms, car parks and service corridors, where impact and heavy use would damage a timber leaf. Many projects use both, chosen opening by opening.

Can a timber fire door have glass?

Yes, using fire-rated glass in a tested glazing system. The glass, beads, intumescent glazing seals and fixings are all part of the rating, and the glazed area and its position in the leaf must stay within what was tested for that door. If you need a large vision panel, send us the size and we will check it against the test evidence.

Why do installation gaps matter so much?

The gaps between leaf, frame and floor are part of what was tested. If they are too wide, intumescent seals may not close them in a fire and smoke passes through. If they are too tight, the door binds and fails to close. The frame must also be fixed and sealed to the wall as tested, and gaps should be checked at handover.

Do timber fire doors need regular inspection?

Yes. Fire doors should be inspected at least once a year, and more often in busy buildings. Check that the door closes and latches on its own, that seals are intact and not painted over, that gaps are within limits, that glazing and beads are undamaged, and that no hardware has been swapped for non-rated parts. Damaged lippings or faces should be repaired by a competent person.
