CareHomeDeskCareHomeDeskCE marking, hinges, closers, intumescent seals -- what you need on every fire door and why.
A fire door is not just the leaf -- it is the complete door set: leaf, frame, hinges, closer, intumescent strip, smoke seal, ironmongery and any glazing. All components must be appropriate for the fire rating required. Mixing components from different manufacturers, or replacing a component with a non-certified alternative, can void the fire certification of the entire set.
Hinges: minimum three per door, all CE-marked to EN 1935. Door closer: CE-marked to EN 1154, set to close and latch from any position. Intumescent strip: must be continuous around the full perimeter of the leaf. Smoke seal: required in corridors forming escape routes. Hold-open devices: must be linked to the fire alarm system and fail-safe (release on alarm).
The maximum gap between door leaf and frame is 3mm on the sides and top, 4mm at the bottom. Gaps larger than this compromise the fire and smoke resistance of the door. If gaps exceed tolerance, the door closer may need adjustment -- but if the frame or leaf is warped or damaged, replacement is required.
CareHomeDesk gives you compliance checklists, maintenance logs, and contractor management tools built around exactly this kind of knowledge.
