What is a fire door??

Wether you are planning on having a loft extension or you’re a landlord and you want make sure that your property meets the regulations, fire doos have become compulsory in the rental properties and the workplace. Knowing how to identify and check a fire door may just save your life and fortunately, a fire door is relatively easy to identify thanks to certain signs. In the event of a fire, knowing that you can count on a minimum of 30 minutes of fire resistance delivers peace of mind allowing you to put together a fire escape plan

We would often get calls or emails asking “can we replace a door and fit a fire door“ Unfortunately, every borough has different requirement and we always recommend checking with building control prior to installation. When it comes to installing fire doors, linings, frames and ironmongery I’ve given a small guide that will help you to check if the doors in your home or business doors meet the current regulations.




The fire door check guide



Use your phone’s camera to check for certification labels or plugs. These are usually located on the top of the door, or occasionally to the side. If you can’t find any labels, check the status of the doors with the manufacturer.

Intumescent papers

All hinges, locks and latches should be fitted with intumescent papers. These will expand to block any gap in the event of a fire. 


An intumescent strip is made from material that conducts heat poorly and will swell on contact with heat. This provides an exceptionally secure seal against smoke and flames which can’t pass through any cracks in the door. If no seal is visible or you can detect seals but they’re damaged, take appropriate action to have them made safe.



There should be at least three hinges, all firmly screwed into place. If screws are missing or broken then the hinges may malfunction and stop the door from functioning effectively. A poorly maintained fire door is also more likely to fail in the event of fire.



Now open the door a few inches and let go. It should close by itself and latch firmly. Check whether it sticks or scrapes on the floor or the door frame. Fire doors that are wedged open or won’t close securely are useless in the event of a fire so make sure that every part of the closing mechanism is in good working order.

Fire foam

Fire-rated expanding foam is an essential item to have when fitting a fire door. The expanding foam will fill gaps around your door frame to prevent the passage of smoke and fire. 

Door Frames and linings

All frames and linings used with a fire door should be fire-rated and should match the same certification, so for an FD30 rated fire door, you will need an FD30 rated frame, lining and casing. Each fire door is rated based on the lowest rated element.
