Fire Doors and Shutters
Fire doors and shutters records whether openings between fire compartments are protected by self-closing, fire-rated doors, gates or shutters, as queried in property insurance proposal forms.

Typical proposal-form questions
- Are all openings between fire compartments (doors, gates, shutters, conveyor and duct penetrations) fitted with fire-rated closures matching the required fire resistance rating?
- Are fire doors and shutters self-closing or automatically closing on alarm, and are they kept free of obstructions and wedging?
- Are closures inspected and function-tested at the required intervals?
Evidence
- Compartmentation and fire-rated closure plan
- Product certification / fire resistance rating documentation
- Function test and inspection records
Why it matters for underwriting
Fire compartmentation only works if every penetration through a fire-rated wall or floor, whether a door, a loading gate or a duct opening, is closed with a matching fire-rated closure. A single door habitually wedged open, or a shutter with a lower rating than the wall it sits in, can undo the loss-limiting effect of an otherwise well-designed compartment layout, allowing a fire to spread far beyond the area it would otherwise have been confined to. Underwriters therefore treat closures as the practical test of whether compartmentation, as drawn on paper, actually functions on site.
Capturing the attribute and evidence
Proposal forms ask whether all compartment openings carry fire-rated closures matching the wall or floor rating, whether these are self-closing or close automatically on alarm, and whether they are kept clear of obstructions. Underwriters look at the compartmentation and closure plan, product certification confirming the fire resistance rating actually installed, and function test or inspection records, since closures that fail to latch or that are propped open during operations provide no protection despite being present.
Effect on coverage, premium and conditions
Fully rated, correctly functioning and unobstructed closures support the premium credit given for compartmentation generally and reduce the probable maximum loss assumed for a single fire event. Missing or mismatched ratings, doors regularly found open or wedged, or the absence of a testing regime typically lead to a condition requiring remediation or a formal no-obstruction policy, and can reduce the loss-limiting credit otherwise given to the compartment layout.
Mitigation measures
Where closures are missing, mismatched or poorly maintained, insurers and risk engineers typically recommend installing closures rated to match the surrounding construction, fitting self-closing or alarm-linked automatic closing mechanisms, enforcing a strict no-obstruction policy through staff instruction and signage, and including all closures in a regular function-testing programme.
