THE IMPORTANCE OF FIRE DOORS

Fire doors play a critical role in protecting lives and property during a fire.

They are specially designed to slow the spread of flames and smoke, giving occupants valuable time to escape and helping emergency services respond more effectively.

When properly installed and maintained by an accredited installer, fire doors can significantly reduce fire damage and meet legal safety requirements.

They’re not just a building regulation, they’re a vital safety feature in any commercial, industrial, or residential property.

OUR FIRE DOOR INSTALLATION PROCESS

We follow a detailed installation process to make sure every fire door we fit is safe, compliant and ready for use. Here’s what that involves:

Frame Preparation: We securely fix the frame in place, using fire-rated sealants and packers to ensure a precise fit and prevent warping. This guarantees the door performs as intended in a fire.

Hanging the Door Leaf: The door leaf is mounted with fire-rated hinges, maintaining 2–4mm edge gaps to stop the spread of smoke and flames. For smoke-control doors, we meet BS 8214 standards, with every measurement checked and re-checked.

Ironmongery Installation: All hardware is installed using approved fixings, fully compliant with the door’s certification. Any adjustments are minimal and properly sealed to maintain fire resistance.

Intumescent Strips & Smoke Seals: We fit certified intumescent strips and smoke seals to the door edges. These expand in heat and must never obstruct closure, so every seal is thoroughly checked.

Linear Gap Sealing: Remaining gaps around the frame are filled with fire-rated materials (e.g. BS 476 or EN 1366-4 compliant foam). BS 8214:2016 guidance is followed when specific instructions are absent.

Self-Closing Device: We install and test a certified self-closing device suited to your door, ensuring smooth, consistent closure. For outward-opening doors, fire-rated angle brackets are fitted if needed.

FAQS

Who Can Install Fire Doors?
It is vital that fire door fitting should only be conducted by competent fire door installers with the necessary training and experience. This is because incorrectly installed fire doors will not provide adequate protection for occupants or the building. A competent person is someone who has professional experience in this field, understands the relevant fire door regulations, and is specifically trained to install fire doors.
Carpenters, joiners and builders are not necessarily trained in fire door safety, which is why you should only consider qualified fire door installers for this important task. If you require fire door installation for your building, we also recommend that you look for someone who is accredited by a third party for complete peace of mind, and proof that they demonstrate the capability, traceability and quality of work required. As fire safety experts, we’re fully accredited and qualified to help with all your fire door needs. Get in touch today.
How Often Should Fire Doors be Replaced
While there is no defined law on how long a fire door lasts before it needs replacing, the condition of every fire door should be checked at least every 6 months. This is to ensure they remain in good working order and preserve the fire compartmentation of your building. If your door is in a high-traffic area and therefore used more frequently, then the rule of thumb is that it should be checked more regularly.
How Long do Fire Doors Protect For?
At a minimum, a fire door must be able to resist fire for 30 minutes. However, some specialist fire doors can last even longer. Each door is given an “FD rating” which tells you how long it can keep the fire out. The different ratings you generally find are:
- FD30: Withstands fire for at least 30 minutes
- FD60: Withstands fire for at least 60 minutes
- FD90: Withstands fire for at least 90 minutes
- FD120: Withstands fire for at least 120 minutes
The specific type of fire door used depends on the type of building, location, and the individual fire strategy. Your passive fire protection specialists will advise accordingly.
What are the Most Common Fire Door Failures
The main reason that fire doors must be installed by a competent person is because a fire door is much more complex than a regular door. Fire door installation includes the door leaf, doorstop, frame, smoke seals, hinges, latches, closers, locks, and more. All of these components must be certified and correctly installed for the door to be fully effective. Any one of these parts, when poorly fitted, could render the door ineffective. Common fire door failures or faults include:
- Doors incorrectly installed or damaged
- Excessive gaps around the door
- Fire seals incorrect, damaged or missing
- Incorrect or unclear fire door signage
- Incorrect, faulty or poorly fitted hinges
- Faulty door closers
As well as proper fire door installation being crucial, maintaining a fire door is just as important. Properly functioning fire doors can be guaranteed with regular fire door surveys.
