Composite Fire Doors

Fire doors don’t always need to be traditional, with a wide variety of styles and colours available it's easy to customise how your fire door looks.

The composite fire door range has been fire and smoke tested for up to 30 minutes (FD30s) by Warrington Exova and independently assessed by Certifire (CF5324). All fire doors have been tested to BS476 Part 22, and subject to the Q-Mark enhanced security scheme. Each fire door in the range is manufactured to a high level of security and complies with PAS023/PAS024 security accreditation as well as Secure by Design (SBD) requirements. Purchasing a third party certified door will provide total reassurance that it is a fully tested, uncompromised fire door.
