Our fire doors come in a wide range of styles, sizes and configurations. From simple single-swing single leaf pedestrian doors – which are used extensively in flats, nursing homes, offices and hotels for example – through to large double-leaf, double swing doors – which are mainly used in commercial buildings, for example offices and hospitals.
All of these products have been designed and certified to meet standard times for fire resistance. The most common time periods for fire resistance are 30, 60, 90 and 120 minutes. Building Life (Fire Doors) Ltd manufactures its doors to the 30 and 60 minutes of fire resistance standard.
Our fire doors come in an extensive range of sizes, finishes and configurations with or without glazed apertures, and can be provided with a wide range of finishes from ply for paint / MDF for paint, laminate veneers / plain colour paints.
Fire door applications
In the UK, the use of fire doors is controlled by Building Regulations. These Regulations mainly cover life safety issues. However, it is not unusual for fire doors to be required by insurance providers or building users, either in additional locations or with fire resistance periods in excess of those recommended by Building Regulations for specific property-related purposes.
General areas of applications are:
- Internal doors within domestic dwellings over three storeys, e.g. Kitchens
- Entrance doors to residential flats (off common areas)
- Doors to protected shafts (in escape routes from medium / high rise flats / houses of multiple occupation)
- Doors providing compartmentation in buildings used by the public, such as in offices, hospitals, schools and hotels
- Protection of escape routes in public, commercial, retail industrial buildings
- Doors to service ducts / cupboards in communal areas of blocks of flats.
The No. 1 Golden Rule
The installation of fire doors is critical to their ultimate performance. Fire Doors should either be supplied as a finished doorset or as individual components that are clearly identified as relating to a competent installer who is certificated under a recognised third-party installer scheme, for example; FIRAS.
Factors that can affect performance
It is only practical for a manufacturer to fire test a limited number of door assembly variations. Ideally the scope of the resulting approval will be detailed in the manufacturer’s third-party certification or will be incorporated in an assessment issued by a testing organisation accredited by the United Kingdom Accreditation Service (UKAS), for example; Warringtonfire. This will show the limitations within which individual fire doors may be used. These limitations will encompass.
- Overall dimensions
- Configurations (pairs, singles, single-swing, double-swing, etc.)
- Style of door (glazed / part glazed, flush face, etc.)
- Fitting and type of acceptable hardware, including closers
- Acceptability of glazed openings
- Dimensions of glazed openings
- Types of acceptable glass
- Type and material of supporting structure i.e. the Frame
- Methods of fixing frames into openings
What to look for on-site
If you are inspecting fire doors on-site and need to verify the efficacy of a fire door installation, you should compare the following with the fire door certification specification:
- Evidence of correct use of components
- Correct fitting of components
- Correct fitting of fire door leaf and frame
- Correct intumescent seals
- Correct gaps and filling between frame and wall structure
- Correct brand of glass, size of glass and glazing method to achieve the designated fire performance for the assembly
- CE-marked hinges
- Evidence that other items of hardware fitted will not compromise the performance of the doorset in the event of fire.
Compare what is provided with the details of the certification and assessment OR for complete assurance, check that the fire doors have certification labels fitted of a recognised third-party product certification scheme, for example BWF-Certifire, and a third-party installation certification scheme, for example FIRAS.
