Frequently asked questions

A fire door is designed to resist the spread of fire when closed. The leaf, frame, seals, glazing and ironmongery need to work together. If smoke control is required, specify it separately.

They indicate 30, 60, 90 and 120 minutes of fire resistance under the relevant test conditions. The rating depends on the construction and the components covered by its evidence. See our fire door range.

Ask for documentation that supports the rating and configuration you need. Check that it covers the proposed size, frame, glazing, seals and hardware, as applicable. If the project specifies third-party certification, check the certificate scope for the product being supplied.

Our Q-Mark certification covers our certified flush fire door range. Panelled fire doors and glazed screens sit outside that scope and rely on separate test or assessment evidence where a fire rating is offered. See our Q-Mark page for the certificate and scope.

The requirement depends on the building, the location of the opening and the project’s fire strategy. Ask your building control body or fire safety adviser to confirm the required performance, then send us the specification so we can review the options.

Use a competent installer who can follow the manufacturer’s installation instructions and the specification for the door or doorset. The supporting evidence determines which frame, seals, ironmongery and installation details can be used.

There is no single interval for every building. Follow the building’s fire risk assessment, the applicable requirements and the manufacturer’s maintenance instructions. If you manage a building, confirm the inspection schedule with the responsible person or your fire safety adviser.

Send the existing frame details, leaf size, seals and hardware. If fire or acoustic performance is required, the proposed combination needs to be checked against the supporting evidence before ordering.

Yes. We manufacture to order for both private and trade customers, from a single replacement door to a full project.

Send your sizes and quantities, the finish and any glazing or hardware requirements. Include the required fire, smoke or acoustic performance if specified. You can attach drawings, photos or a door schedule on the Get a Quote page.

Yes. Use Design Your Door to sketch a flush or panelled door and download a drawing. Include it with your enquiry so we can review the design and the performance you need.
