An FD60 fire doorset provides a minimum of 60 minutes' fire resistance, evidenced by testing to BS 476-22 or BS EN 1634-1 and, on the European route, classified under BS EN 13501-2 (FD60 broadly corresponds to E60). FD60 is specified where a fire strategy or Approved Document B calls for more than the standard 30 minutes — typically doors protecting stairways in taller buildings, doors in compartment walls, plant rooms and other positions where longer containment is required.
Each FD60 doorset we supply will be manufactured as a complete certified unit under a third-party scheme: a thicker, denser leaf construction, a frame profile matched to the tested design, intumescent sealing specified for 60-minute performance, and ironmongery selected from within the certification's field of application. Because the whole assembly is tested together, the certificate covers the opening as installed — not just the leaf.
Where the specification calls for smoke control alongside fire resistance, the FD60s variant adds cold smoke seals. We will deliver every doorset with its certification evidence, installation instructions aligned to BS 8214, and the specification data needed for Regulation 38 handover and golden thread records on higher-risk buildings.

Frequently asked questions
When is FD60 required instead of FD30?
FD60 is specified where the building's fire strategy or Approved Document B requires 60 minutes of fire resistance rather than 30 — commonly doors protecting stairways in taller buildings, doors in compartment walls, and higher-hazard rooms such as plant and switch rooms. The correct rating for any opening comes from the fire strategy and risk assessment, not from a general rule.
Is FD60 the same as EI60?
No. FD60 broadly corresponds to E60 under BS EN 13501-2, which is an integrity classification. EI60 additionally requires insulation performance — limiting temperature rise on the unexposed face — and is a stricter criterion. If a specification calls for EI60, it needs a doorset with EI classification evidence, not simply an FD60 doorset.
How thick is an FD60 door?
FD60 door leaves are typically 54 mm thick, compared with the typical 44 mm of an FD30 leaf, although the governing document is always the certified design. Thickness alone does not make a fire door: the rating depends on the tested combination of core, frame, seals, glazing and ironmongery.
