The table below summarizes the main customization options buyers can discuss with a custom fire door manufacturer.

Frequently Asked Questions
1. Why choose a custom fire door instead of a standard fire door?
A custom fire door can be manufactured around non-standard opening dimensions, specific finishes, glazing requirements, frame conditions, hardware requirements and project specifications. This is particularly useful in refurbishment, heritage, apartment, commercial and architectural projects where standard off-the-shelf sizes may not fit the existing opening.
2. Can custom fire doors include acoustic performance?
Yes. Some UK manufacturers combine fire and acoustic performance within the same doorset. This is particularly useful for hotels, apartments, healthcare buildings, offices, schools and residential developments where a door may need to control both fire and sound transmission. The required acoustic rating should be specified together with the fire rating at the quotation stage.
3. Can UK manufacturers make FD30 and FD60 fire doors in non-standard sizes?
Yes. Bespoke FD30 and FD60 fire doors are available from several UK manufacturers, although the permitted dimensions depend on the manufacturer's tested or certified scope. Buyers should provide the exact structural opening, door leaf dimensions and doorset requirements before ordering rather than assuming that any fire-rated door can simply be resized.
4. Can I order a bespoke FD90 or FD120 fire door in the UK?
Yes. Some specialist manufacturers offer higher-rated bespoke doorsets, including FD90 and FD120 solutions. Enfield Doors, C W Fields & Son and Hanson & Beards all have product or certification information covering higher fire-resistance levels. The exact maximum dimensions and configuration must be confirmed with the manufacturer for the required application.
5. Can custom fire doors include glass or vision panels?
Yes, but the glazing must be compatible with the tested or certified fire door configuration. The glass type, dimensions, frame, glazing system and installation method can affect the fire performance. Custom glazed fire doors and fire-rated glazed screens are available from specialist manufacturers, but buyers should not add a standard glass panel to a certified fire door without confirming that the complete configuration remains compliant.
