  • A well designed fire door will perform its duty in providing access around a building
  • In the event of fire it will stop the fire from spreading for a specified period, protecting egress routes
  • Doors fitted with smoke seals will prevent the spread of cold smoke
  • The correct installation of fire doors is necessary for the door to perform its duty
  • Evidence confirms that a maximum of 4 mm to the jambs and heads is essential to meet specified fire performance
  • Smoke leakage can be prevented without any sealing to the threshold but this dimension is 3 mm between the bottom of the door to the floor as defined under BS9999: 2008
