Faqs

Q: When are fire doors required?
A: Basically wherever a fire might start, it is advisable to use a fire door. For example, doors leading from: a kitchen; a lounge with a fireplace & TV; or any room with electrical equipment or flammable items.

Building regulations for domestic properties stipulate when fire doors should be used and the key areas are:
  • If a 2 storey house has a door leading from an integral garage into the house it must be a fire door.
  • New build or renovated properties with 3 storeys or more, including loft conversions, must have FD30 fire doors to every habitable room off the stairwell.

Local councils issue planning permission and are responsible for policing building regulations through Building Control Officers. The architect who has specified the project is the best first point of call, regarding fire door requirements and regulations. Commercial property regulations are substantially different and it’s rare that a commercial building does not have some fire doors.


Q: How fire doors work?
A: A fire door must be fitted with approved intumescent strips which play a crucial part in achieving the fire door rating. When subjected to heat, the intumescent strips expand and seal the gap between the door edge and the frame. Intumescent seals can be fitted within the door frame or grooved into the door edge. Advice on the intumescent strips can be obtained from the test evidence report, which we can provide.

The material from which the door frame is constructed (e.g. softwood, hardwood or MDF), as well as its section sizes must comply with the required standards. Furthermore, essential hardware (ironmongery) must also have its’ own individual test evidence to show fitness for purpose.


Q: How is fire exit hardware different from panic hardware?
A: When panic hardware is used on fire doors, it must be fire exit hardware, which bears labels for both panic and fire resistance. A door with fire exit hardware will also have an additional label, indicating it is equipped with fire exit hardware. Fire exit hardware does not incorporate a mechanical dogging feature—the means to hold the latch retracted using a key, thumb turn, or Allen wrench. For fire doors where a ‘push/pull’ condition is desired, fire exit hardware with electric latch retraction may be used, as long as the latch projects automatically upon fire alarm, to secure the door.

Some vertical rod fire exit hardware for pairs of doors can be installed ‘less bottom rod’ (LBR). These devices use the top rod and latch only, with no bottom rod or latch. The advantage is there is no floor-mounted strike, and no bottom rod or latch to become damaged by carts or traffic. This configuration can sometimes cause a reduction in security, because it may be more easily defeated with only one latching point at the top of the door. In most cases, doors with LBR devices are required to have an auxiliary fire pin, which mounts in the edge of one door and projects into a hole in the edge of the other door if there is a fire.


Q: Do I need seals?
A:Yes, combined heat and smoke seals are designed to stop the spread of smoke and fire and to form a seal between your fire door and frame in a fire situation. As smoke is the leading cause of death in case of a fire the seals are an absolute must.
