Fire doors are precision safety devices. Even small installation errors can render them non-compliant and ineffective in a fire. Here are the mistakes we see most often.

Common Installation Errors

• Incorrect Gap Sizes: The gap between the door and frame must be 2–4mm. Too large and smoke can pass through; too small and the door won’t close properly.
• Missing or Damaged Intumescent Strips: These strips expand when heated to seal gaps. If they’re missing, painted over, or damaged, the door won’t provide its rated protection.
• Wrong Number of Hinges: Fire doors require a minimum of three hinges. Using only two is a common shortcut that weakens the door’s performance.
• Non-Rated Hardware: Handles, locks, and letter plates must be fire-rated. Standard hardware can create weak points in the door’s fire resistance.
• Propping Doors Open: Fire doors must be self-closing. If they need to be held open, only approved electromagnetic hold-open devices linked to the fire alarm should be used.

The Importance of Certification

A properly installed fire door should have a visible certification label or plug on the top edge. This confirms the door has been tested and meets the required standard.
