usually 1½  pairs made of metal with melting point above 800°C.

Rising butt or spring hinges are NOT permitted.

What closers should I use?

Closers (on non-latched doors) MUST be CERTIFIRE Approved. There are two types:

  • Face-fixed overhead closers fixed to the face of the door or frame which automatically closes the leaf from fully open position
  • Concealed / spring closers which are concealed in the door leaf and use a spring to close door from open position.

What latches should I use?

Mortice or tubular mortice must comply with BS EN 12209. These may be lockable or un-lockable types depending on door requirements.

Yes you can, but they MUST be tested and CERTIFIRE Approved.
You must also check that the door has been certificated for use with letterplates / letterboxes.
Check the fire door manufacturer's instructions, or if in doubt, contact the door manufacturer.

(The aperture for a letter plate may be formed on site by NON-CERTIFIRE approved staff, however, the letter plates fitted MUST be CERTIFIRE approved for the appropriate application and fitted strictly in accordance with the specification detailed in the manufacturer's CERTIFIRE data sheet).
