Timber Door
In order to gain CERTIFIRE approval, the following instructions shall be complied with in their entirety. Failure to do so will invalidate the approval and may jeopardise the fire performance of the door. The supplied doorset shall not be altered or modified in any way nor should the supplied hardware be changed, removed or additional items (not specified) fitted. To do this may invalidate the certification.
General Requirements for CERTIFIRE certificated timber doors
All essential hardware items, including closing devices and intumescent edge seals, shall be CERTIFIRE approved or otherwise as specified in the data sheet specific to the doorset as should all glasses and glazing materials.
The doorsets shall be mechanically fixed to wall constructions having a fire resistance of at least equivalent to that intended for the doorset.
Door assemblies supplied pre-fitted with components by the certificate holder may be considered to meet the requirements in respect of those items.
The approval may be applicable to both complete doorsets and door leaves. Where the door is not supplied in a completely fitted form it is a condition of the approval that an agreed data sheet accompanies the product and the requirements are complied with in their entirety.
The leaf carries a prefixed label on the top or hanging edge of the door leaf, issued under the terms of the CERTIFIRE scheme. This label uniquely identifies the door leaf, the manufacture of which complies with BS: ISO 9001 for quality systems and is subject to on-going surveillance. This label shall not be removed. Labels will reference manufacturer,CERTIFIRE,CERTIFIRE Ref. No. and intended fire resistance performance.
Glazed apertures and apertures for non edge mounted hardware items (ATG/Louvres etc)
Apertures should not be cut from the door leaf on site. This type of activity will invalidate the certificate. Only apertures factory cut by the door leaf producer or by licenced modifiers certificated by CERTIFIRE are acceptable means of cutting apertures within the leaf. These modifiers are listed in the Door Modifiers on the left side of this web page.
Supporting Construction
In general the door assemblies are approved to be installed in brick, block, masonry, or timber stud of minimum thickness 70 mm, providing at least 30 minutes fire resistance.
Installation
Door leaves may be trimmed to fi t the frame by the following maximum amounts:
- Stiles (each) 3 mm
- Top 3 mm
- Bottom 5 mm
Hinges
Hinges shall be CE marked in accordance with EN 1935 for use on fire resisting timber doors.
Latches
Latches are not required to be fitted when an appropriate closing device is used although where fitted the latch shall be CERTIFIRE approved for use on fire resisting timber doors.
Self Closing Devices
All unlatched doorsets shall be fi tted with a suitable door closing device. A self-closing device is normally required to be fitted to satisfy fire regulations and if fitted shall be a CERTIFIRE approved product. Note: closers with mechanical hold-open mechanisms are not permitted to be used.
