We supply and deliver most of our fire doors within 48-72 hours anywhere in the UK.
Fire safety is a huge concern for many of our customers, and installing fire doors can be an important requirement for landlords and business owners alike. But a fire door isn’t just a check in a box; they are fundamentally important in protecting buildings, livelihoods and, of course, lives.
We can help:
At Direct Doors, we know doors, and on this page we’ll help you understand the different types of fire rated doors available, and select the right ones for your situation.
Internal fire doors are primarily designed to restrict the spread of fire, and are required to perform three main functions:
- To protect all escape routes from the effects of fire (including smoke) so occupants can leave safely;
- To protect the contents and/or structure of the building by limiting the fire spread (an insurance requirement);
- To permit fire fighting to be carried out safely.
Each and every one of our fire doors - including glazed fire doors - are fully certified. Our door suppliers are able to provide proof of performance, showing that the door successfully completed a rigorous fire text to the BS 476 Part 22 standard, or the European equivalent BS EN 1634.
Fire door pairs are shown only as a visual indication as to how they might look in situ. However, the certification relates only to a single door, and you must double check with your planning and/or fire officer as to the requirements of compliance prior to ordering.
Regulations - Need to know:
Building regulations specify requirements for fitting fire doors, and the minimum time for protecting a building’s occupants is expressed in minutes. Typically this is 20, 30, or 60 minutes, and most tradesmen will use the terms FD30 and FD60, which relate to the 30 and 60 minute ratings.
Note: We have been asked on numerous occasions to source or supply 35mm fire doors. However, to date we have not been able to obtain any that would match or comply with the fire testing requirements that must be met or exceed during testing.
The fire doors included in our range are tested as a complete assembly, including the frames, intumescent seals, and essential ironmongery. They will only be guaranteed if the tested design is replicated with the correct, compatible components.
Please ask for a copy of the test evidence when fitting these doors. Read More: Why do I need to fit fire doors?
We currently stock two different fire-rated doors: FD30 and FD60.
Your budget and your situation will typically dictate the type of fire door you should install.
- FD30: Glass, panelled and flush are usually 44-45mm in thickness, as opposed to the standard door thickness of 35mm.
- FD60: The one hour fire-rated doors are normally 54mm. These are usually more expensive due to the restricted choice and the required construction methods. They are most commonly used in commercial settings.
Construction and Installation:
The material from which the fire door frames are constructed (for example, softwood, hardwood, or MDF), as well as its section sizes, must comply with the required standards. What’s more, essential hardware (ironmongery) must have its own individual test evidence to prove fitness for purpose.
Most fire-rated doors in the UK have a solid core construction which can include: particleboard, chipboard, flaxboard, and solid timber.
The assembly can vary greatly; some have a timber framing around the core with a laminated veneer, while others have a lipping (measuring 5 - 20mm thick) around the core, with a veneer on top. It’s important to note that there is no preferred, or indeed regulated construction method, and no need for one so long as the desired fire rating is achieved.
For a fire-rated door to be truly effective, it must be fitted with approved intumescent strips.
When subjected to heat, the intumescent strips expand, sealing the gap between the door edge and the frame. The strips can be fitted within the door frame, or grooved into the internal fire door’s edge.
Further advice on the intumescent strips can be obtained from the test evidence report, which is available from the door supplier or manufacturer.
Our panel fire doors are suitable for use in both flats and houses. In addition to satisfying the most rigorous of fire regulations, our internal and external fire doors have to look the part and will suit just about any décor.
Most doors are supplied in a range of materials, including white primed, oak, cherry, ash, walnut and mahogany.
Modern properties are usually fitted with external fire-rated doors as standard, and these are usually flush fire doors. This is due to our greater understanding of the importance of containing a blaze to allow the maximum time possible to vacate a burning building.
Note: Some planning authorities require intumescent fire and smoke seals to be fitted to the top and sides of internal fire doors. They may also want door stops to be 25mm thick, and some form of closer may be required. Hinges also have to measure up to suitable fire rated standards - there is no escape (no pun intended) if the wrong hinge is used.
