Frequently asked questions:
Q: How thick are your fire doors?
Our 30 minute fire doors (FD30) are 44mm thick
Our 60 minute fire doors (FD60) are 54mm thick
Q: How much can be removed from each edge of a fire door?
The amount that can be removed from the edges of a fire door differs from one door to the next and depends on several factors, including the exact materials used during construction and guidelines from the fire rating certificate. Accurate trimming information can only be provided by the manufacturer on a case-by-case basis after the door has been completed.
Q: How long do fire doors last?
There are no set rules that detail how long a fire door lasts before it needs to be replaced. The condition of the door should be monitored and checked at least every 6 months to ensure it is in good working order. Fire doors should comply with the latest fire door regulations and so it is important to keep up to date with any changes in regulations which may mean your doors are no longer fit for purpose.
Q: Do your fire doors satisfy disability regulations?
All our fire doors satisfy the DDA regulations.
Q: How do you calculate the weight of a fire door?
In order to calculate the weight of a fire door you will need to know the weight per square meter (kg/m2) of the doors core. This is determined using the thickness of the door as follows: 44mm = 55kg 54mm = 75kg The calculation below can be used to determine the approximate weight of the fire door. Please note that the calculation does not take glass weight into account. Width X height X thickness X kg/m2 of the door’s core = Weight of fire door. For example for a door that was 926x2040mm with a thickness of 44mm the following calculation would give an approximate weight: 0.926 X 2.040 X 0.44 X 55 = 45 KG.
Q: Can I update existing fire doors that have no seals to conform to regulations?
Yes, fire door seals can be fitted to either the door or the frame
Double doors or door and a half fire doors will need to have fire door seals fitted to the door to ensure that the gap between each leaf is taken into consideration.
Q: What are closing force ratings for fire door closers?
The closing force rating of fire door closers, also called “power size”, relates to the maximum width and weight of fire doors that the door closer can reliably close and hold closed.
Q: Can a fire door be fitted with self closing hinges?
Whilst it is possible to fit self closing hinges to a fire door, Safelincs does not recommend their use as they slam the door quickly.
Q: Can I wedge my fire door open?
Fire doors should never be propped or wedged open as the fire door would not be able to close in the event of a fire. A safe and legal solution to holding open fire doors is to install a fire door holder also known as a retainer. Fire door retainers can be easily installed onto existing doors and allow the door to be held open at any angle. They comply with regulations because when the fire alarm sounds, the door retainer releases the fire door to close, preventing the spread of fire. Fire doors should never be propped or wedged open to improve ventilation.
Q: Can I cut the bottom off my fire door to increase air circulation?
Cutting the bottom off a fire door could threaten the integrity of your fire door and could put lives at risk. If you need to increase air circulation in your building the best option is to hold your fire door open with a fire door holder or free-swing door closer. These are legal solutions that enable a fire door to be left open but will activate the automatic closing of the fire door on the sounding of fire alarm, preventing the spread of smoke and fire.
Q: Can you make alterations or drill holes in a fire door?
Yes, in some cases you can make alterations to your fire door, however these alterations can only be done if they remain within the scope of the fire door’s Certifire Approal documents. For example when a fire rated door viewer or intumescent letterbox / letter plate is required. This information should also be detailed in the installation and maintenance instructions supplied with each door leaf.
It is critical that any changes made to a fire door is done so following the manufacturer’s instructions, by a trained professional, and with certified hardware to ensure that the performance of the door, and it’s associated certification, is not compromised.
BWF-Certifire have created a guide on how to ensure you retain your Fire Door Certification when considering making alterations.
Q: Are intumescent strips required on fire doors?
Yes, intumescent fire seals are required on all fire doors. Newer doors and frames have a channel cut into them for rebated seals (if not supplied with seals already in place). For older doors, surface-mounted seals can be used instead.
Please note: some of our seals have brushes on them, which are designed to block the spread of smoke around the door before ambient heat has caused the intumescent seals to expand and fill any gaps – these are usually required on doors, so make sure a competent person has performed the appropriate fire risk assessments or fire door inspections before purchasing.
Q: Which rooms need fire doors?
Fire doors must be used in walls which form the compartmentation of the premises – specific areas within the building that are constructed to be fire-resistant. These may be individual rooms, but could also contain multiple rooms or might be vertical risers and lift shafts. Fire-rated doors are not required for walls not part of a compartment boundary.
Additional fire doors can be installed in place of normal doors, but they would provide minimal protection as the walls around them may not be constructed of especially fire-resistant materials and could burn through while the fire door remains intact. There is a risk of occupants gaining a false sense of security if fire doors are installed in non-compartment walls, so this should only be done under the guidance of a proper fire risk assessment conducted by a competent person.
Please consult the original building plans, if available, to determine where your premises’ fire compartments are, or otherwise have a competent person perform a fire risk assessment or fire door inspection.
Q: How do you stop fire doors slamming?
Regulations state that fire doors should self-close completely and reliably. They do not however need to bang or slam shut. The reason for the slamming is usually due to the fire door closer having an incorrect closing speed or power size. Many self-closing devices can be adjusted so that the door will close correctly without slamming shut. Other issues including a loss of fluid or improper fitting could be causing the issue. It is also possible to fit self-closing devices with a latching action which close the door quickly at first and then stop it from slamming by closing the last few inches slowly. It is advisable to have your fire door closer maintained and altered by a competent person.
