The Importance of a Fire Door Label

Third-party certification gives specifiers, local authorities, construction companies and building owners confidence that their fire doors /doorsets will perform as designed in the event of a fire. Certification also provides added benefits such as visibility and traceability of the door’s pathway through the construction supply chain.

When a fire door is manufactured or modified by a BWF Fire Door Alliance member, a label, or labels with unique numbers is placed on the top edge of the door. For Fire Doorsets, the labels may be placed in the frame. The purpose of the number(s) is to provide access to additional information including the fire door manufacturer and, where relevant, the Licensed Processor, as well as any certifications related to its specification and production records.

This allows the original fire door certificate and specification to be sourced, enabling on-site checks to be carried out against the door’s original standards. If this process highlights that any components need replacing, the documents will also outline the parts compatible with the original certification and test requirements to ensure compliance is maintained.

Different Types of Fire Door Labels

The BWF-CERTIFIRE label and new Fire Door Alliance Label provides traceability through the supply chain, ensuring the manufacturer can be contacted if further information on the fire door is required.

The Scheme has a variety of labels to suit the ratings and requirements of different door or doorset configurations. Labels should NEVER be removed from the door.

The label displays the member’s name and phone number, and, where applicable, the certification number, a unique serial number and the door’s fire rating.

Here are some example labels:

Replacement Labels

Although the label should not be removed, accidents may happen.

There are strict rules for the issuing of replacement labels which MUST match the original information.

You MUST provide evidence that the original door has been supplied by the manufacturer or converter, such as the original CF and unique number (if known) and / or invoices from the supplier which enables the manufacture to verify the information. The manufacturer or converter may wish to have a representative visit the site to confirm the information is correct. Please note, there may be a charge for this service.
