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
Fire door testing facts
All our fire doors are certified and our door suppliers are able to provide proof of performance showing the door successfully completed a rigorous fire test to the BS 476 Part 22 standard or the European equivalent BS EN 1634.
All Building regulations specify the requirements for fire resisting doors to protect occupants for a minimum time which is expressed in minutes, either 20, 30, 60 minutes etc, most of the time tradesmen will use the term FD30 and FD60 which relates directly to 30 minute and 60 minute ratings.
The doors are tested as a complete assembly including door frames, intumescent seals and essential ironmongery and can 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.
detailed Construction of fire doors
FD30 (30 minutes) are usually 45mm thick, as opposed to the standard door thickness of 35 mm, there is absolutely no point if fitting a fire rated frame if you then fit a standard non fire door.
FD60 (60 minute) most commonly used in commercial settings are normally 54mm thick. Specially constructed fire doors can have a rating of 4 hours or more, this is very much dependent on fitting ALL of the correct materials.
Most fireproof doors 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, others have a lipping (5-20mm thick) around the core with a veneer on top and in some cases a plywood, veneer or MDF facing is glued on to the core without framing or lippings. There is no preferred or regulated construction method and no need for one as long as the desired fire rating is acheived.
They must be fitted with approved intumescent strips which play a crucial part in acheiving the rating if you wish to adhere strictly to acheiving the test results but our experience is that each planning authority accepts the fire door on its own in terms of compliance with planning when fitted retrospectively.
When subjected to heat, the intumescent strips expand and seal the gap between the door edge and the frame. Intumescent seals can be fitted within the door frame or grooved into the door edge. Advice on the intumescent strips can be obtained from the test evidence report, available from the door supplier or manufacturer
The material from which the door frame is constructed (e.g. softwood, hardwood or MDF), as well as its section sizes must comply with the required standards. Furthermore, essential hardware (ironmongery) must also have its’ own individual test evidence to show fitness for purpose.
Our Panel Fire Doors in these categories are suitable for use in both flats and houses and will suit a wide range of needs, whatever your home’s décor. It is important to us that these doors satisfy the most rigorous of fire regulations whilst also looking great.
Modern flatted properties are usually fitted with external fireproof doors as standard and most of these are Flush Fire Doors, this is due to our greater understanding of the importance of preventing and containing a blaze to allow the maximum time possible to vacate a burning building.
Please remember some planning authorities require intumescent fire and smoke seals to be fitted to the top and sides of any of this type of door, 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.
Our FD30 rated doors, including Fire Doors with Glass are as usually 45mm thick whilst those rated FD60 are 54mm thick, please make allowances for the correct frame when purchasing these doors and note that most doors are supplied in a range of materials including white primed, oak, cherry, ash, walnut and mahogany.
