Installation

How do I install a fire door?

Fire doors are an important element in the fire safety of a building, but too often everyone assumes that someone else will ensure their quality and performance. The installer’s job is simply to fit it!

A certificated half hour fire door which is incorrectly installed may only provide 5-10 minutes of fire resistance.

Before installation, check out:

  • The label on the door and frame – it is evidence that the door and frame is certified
  • 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
  • The gap between the door and the frame – is important and should be 3mm
  • CERTIFIRE approved and CE marked ironmongery – to ensure compatibility
  • Correct CERTIFIRE approved seals – must be installed with the fire door

The correct installation of fire door assemblies and doorsets is fundamental to their overall performance because it will ensure the fire door will remain reliable to its fire integrity rating in the event of a fire.

Incorrect installation defeats the purpose of certificated fire doors, certificated components and certificated hardware because in a fire, the smoke and gases it produces can easily travel through the gaps left by incorrect installation.

Checking fire door installations isn't always a straightforward exercise. We have a series of publications which will help you in this task.
Visit our "Publications" section for the latest guidance documents.
Our publication "Fire Doors - the burning issues" also contains a checklist to show you what to look for.

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.

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. Use our directory or search facility to find a company who is licensed to provide certificated doors with apertures.
