What you can do within certification scope

Every component within a fire doorset or fire door assembly can have an effect on the fire performance. Making changes to any of these components, especially the door leaf, can have a significant effect on its fire performance.

Some alterations are allowable on a fire door provided they are within scope of the fire door’s ‘Certifire Approval’ documents (CF certificate and data sheet).

This information should also be contained in the installation and maintenance instructions supplied with each door leaf.
