Fire door compliance

Fire doors are an important part of the fire control measures of most buildings, acting not only as a barrier to contain the spread of fire but also protecting evacuation routes and access for emergency services.

Everyone in the supply chain has a responsibility to comply with fire control regulations. In England and Wales, these obligations are set out in Approved Document B of UK building regulations

Fire Door Construction

Our fire doors are designed to resist smoke and flames for a specified minimum length of time. Denleigh supply doors which are FD30 and FD60 fire rated. FD30 doors are a typically 45mm thick and FD60 doors 54mm thick and as a result they are also heavier than a standard door. Our fire doors are typically supplied as a certified doorset, complete with frames and ironmongery.

Glazed fire doors

Fire doors are also available with glazed panels. Glazed doors are popular in corridors, communal areas and on escape routes in apartment buildings reasons of forward visibility. All glazed doors are available with FD30 certification and some designs in FD60 – Contact our specialist doors team to check availability of your chosen door design.

Are bespoke fire doors sizes available?

Fire doors can be supplied in a wide range of standard and bespoke sizes up to a maximum of 2,400mm high x 1,200mm wide. Oversized fire rated doors and double doors for grand entrances make a great first impression whilst helping to protect key areas of the property.


To help ensure correct specification and installation, Denleigh provide guidance on installation. Fire doors should be installed with fire resistant parts, such as door frames, intumescent seals and fire door compatible hardware, all of which we can supply. It is essential to install fire doors in accordance with the guidance to ensure compliance to regulations.

Safe use of fire doors

Only when doors are shut can fire doors slow the spread of fire throughout a building allowing emergency services time to respond. Denleigh supply a range of self-closing devices that ensure doors return to their closed position after use or in the event of a fire alarm being triggered.
