Certified fire doorsets, FD30 to FD120

A fire doorset is a complete tested assembly — leaf, frame, seals, glazing and ironmongery, manufactured and certified together. That is all we will supply: complete doorsets with their evidence.

In short

Fire-rated doors are graded FD30, FD60, FD90 and FD120 by how long the doorset resists fire: 30, 60, 90 or 120 minutes of integrity when tested to BS 476-22 or BS EN 1634-1. FD30 (broadly E30) is the everyday rating for flat entrances and escape routes; FD60 (E60) protects stairways and compartment lines; FD90 and FD120 are reserved for high-hazard compartmentation. The correct rating for any opening comes from the building's fire strategy and risk assessment, not from a general rule.

FD ratings describe integrity (E), not insulation (EI): an FD60 doorset is not the same as EI60. Leaf thicknesses are typical, not mandatory — the governing document is always the certified design. For the two most-specified ratings, see FD30 vs FD60: which rating do you need? or run the compliance checker.

What an FD rating certifiesIntegrity is held back at the door. Insulation is a separate test.
FIRE SIDEPROTECTED SIDE
Integrity (E) — holds back flame and hot gases. This is what every FD rating (FD30–FD120) certifies.Insulation (EI) — limits heat passing to the protected side. A separate test — an FD60 doorset is not EI60.

Compare any two ratings side by side — FD60 vs FD90, FD90 vs FD120, FD30 vs FD90, FD60 vs FD120, FD30 vs FD120.

Pick a rating to see the integrity it holds, a typical leaf thickness, and where it is usually specified — FD30 vs FD60 and beyond, at a glance.

Minutes of integrity E3030 minutes
0306090120 min
Fire resistance E30 — 30 minutes’ integrityResists the passage of flame and hot gases for 30 minutes. Integrity (E) only — it does not limit heat transfer.
Typical leaf thickness 44 mmTypical for a certified FD30 timber leaf; the certified design governs.
Where it’s specified Flat entrances & escape routesDwelling entrance doors, corridors and general escape routes in most homes and offices.

Illustrative selector — not a specification. Figures are fire integrity (E30–E120): resistance to flame and hot gases, not insulation (EI, which also limits heat transfer through the door). Leaf thicknesses are typical; the certified doorset design, hardware schedule and site inspection govern. Pre-launch.

Frequently asked questions

What is the difference between FD30, FD60, FD90 and FD120?

The number is the minutes of fire resistance the doorset gives — 30, 60, 90 or 120 minutes of integrity when tested to BS 476-22 or BS EN 1634-1. FD30 (broadly E30) is the everyday rating for flat entrances and escape routes; FD60 (E60) protects stairways and compartment lines; FD90 and FD120 are for high-hazard compartmentation.

Is a higher fire door rating always better?

No. The correct rating for an opening comes from the building's fire strategy and risk assessment, not the largest number. Specifying a higher rating than the strategy requires adds cost and weight without adding compliance — and above FD60 the design and glazing become more restricted.

Are FD ratings the same as insulation (EI)?

No. FD ratings describe integrity (E) — resisting flame and hot gases — not insulation (EI), which limits heat passing to the protected side and is tested separately. An FD60 doorset is not the same as EI60.

What is a fire doorset versus a fire door?

A fire doorset is the complete tested assembly — leaf, frame, seals, glazing and ironmongery, manufactured and certified together. A fire door often refers to just the leaf. The rating belongs to the whole doorset as tested, which is why we supply complete doorsets with their evidence.

Pre-launch note. Specifications shown are generic certified-doorset characteristics. Certificate numbers, scheme registrations and per-configuration datasheets will be published here when our supply agreements and certifications are granted — never before.
