Building Regulations and Guide:

Fire Door Installed

Fire door installed to meet fire regulations

  • Building regulations require a safe means of escape from a converted loft.
  • How fire will be inhibited is considered along the extent of the exit route.
  • Fire resistant doors and partitions (for open-plan designs) are one option to achieve this and if chosen are needed along this route. An alternative method is to install sufficient smoke alarms.
  • It is difficult to modify existing internal doors to meet the current fire safety specification as fire doors are insulated to protect from heat and fire.
  • This 'integrity' is specified in minutes eg 20 or 30 that the door needs to resist fire.
  • Different time limits are given for different types of property and the use property is put to.
  • Fire doors don't usually have to be self closing unless they are onto a garage, where smoke control is also required.
  • Door hinges need to have a melting point of at least 800 degrees Centigrade, i.e. have steel washers.
  • In most cases it is possible to retain the existing door frame.
  • Being thicker and heavier than existing doors the frames may need stops recessed or replaced, and fixings reinstalled.
  • The operating gap between frame and door needs to be kept to a minimum (3-4mm).
