Internal Fire Doors

Have you ever thought about adding fire doors to your home?

We answer some of the common questions asked about internal fire doors and the benefits of adding them to your home.

What is a fire door?

A fire door manufactured, and when fitted properly with the correct ironmongery and fittings by an experienced joiner – will withstand flames and smoke for a specific period. A fire door is one of the most important elements when it comes to passive fire protection, containing the spread of fire and smoke allowing time for occupants of a building to be safely rescued or evacuated.

How are fire doors different to standard doors?

Fire doors are manufactured to withstand the spread of fire for a given period of time, normally a minimum of 30 minutes. This allows time for inhabitants of a building to escape. Fire doors may be of solid construction or made with a special core, often flax board or a wood composite material that is slow to burn. They are also made with special seals, fitted into either the door or frame, which seal the door on impact with heat, to stop the spread of fire and/or smoke around the edges of the door.

Do I need fire doors in my home?

If you are undertaking a large extension, renovation or conversion your architect will specify internal fire doors if they are required for your project. However, fire doors are essential in the following circumstances:

  • If you have a door leading from a garage to the main house in a two-storey building.
  • If you are building or renovating a home with three or more storeys (including loft conversions).
  • If you have a loft conversion all doors within your home must be fire doors. Building regulations state that you need to create a safe corridor from the loft to the external door, ensuring that if there is a fire anywhere in the house those in the loft conversion can make a safe exit.

It’s always best to consult with your architect or building control if you are unsure.

None of the above requirements apply to me - do I need to replace all the doors in my home with fire doors?

No. If you don't already have internal fire doors in your home, standard doors are fine.

However, adding fire doors to your home can be a great addition. The additional safety measures can keep you and your family safe in emergency situations.
