Fire Door Installation

Fire Door InstallationInstallation of fire doors is as life critical as the product specification itself and should only be carried out by someone who is competent, has been specifically trained to install fire doors and understands their responsibilities in getting it right (and ideally as part of a third party certificated process).  Fire doors that are incorrectly installed and fitted with incompatible components invalidate certification and will not provide adequate protection for occupants or the building.All fire doors supplied through the Fire Door Alliance are provided with installation instructions that are specific to the product. Installation methods and materials can change depending on a number of factors, including product type and installation environment and so it is vital that these are referred to and adhered to.

Key things to remember when installing a fire door:

  • Any individual fitting a fire door should be fully trained and competent to do so
  • Look for a label or a plug to show that the door is certificated and check the instructions/certificate supplied
  • Essential Ironmongery such as locks, latches, closers and hinges MUST be CE marked, firmly fixed with no missing screws and compatible with the door leaf’s certification.
  • The choice of frame/lining/casing and intumescent/smoke seals should also be compatible
  • The instructions on the door – they should be followed to ensure correct installation
  • The frame specification – should be correct for the door’s fire rating
  • The Building Regulations – are you following ALL of them correctly
  • Apertures ONLY from Licensed Converters – DO NOT cut apertures on site.  Cutting apertures for glazing and air transfer grilles will make certification VOID as will trimming the door more than is permitted or planing off certification markings
  • The gap between door and frame at the top and sides should be 2-4 mm and the threshold gap as per manufacturers instructions (typically around 8-10 mm) – the certificate will include details of this
  • Ensure any voids between door frame and wall are tightly packed with mineral wool
  • Check the certificate to ensure that you are only using compatible ironmongery (hinges, closers etc) and intumescent seals (in all the right places)
  • Once complete. check that the closer shuts the door onto the latch from any position

How do I fit glazed or non-glazed apertures in a fire door?

In some situations ‘glazed vision panels’ or ‘glazed apertures’ are required to be added to the door to allow for additional light or vision of the other side of the door.  Non-glazed apertures may be required in the case of louvre panels or air transfer grilles.

It is vital to remember that the addition of ANY apertures will seriously affect the performance of the door unless it is undertaken ONLY by companies that are licensed and approved to carry out this type of work to agreed procedures.  Cutting and glazing apertures must NEVER be undertaken on site and will negate the door’s test certificate.

You can use our BWF Fire Door Alliance Directory to find a company who is licensed to modify doors or provide certificated doors with apertures.
