Yes, Kelly Doors offer a wide variety of 30 minute and 60 minute fire-resisting door-sets designed for internal use.  Working closely with Chiltern Fire we can also design and manufacture project-specific high specification doors, allowing specifiers to use bespoke designs and still meet all the relevant regulatory requirements..

Correct specification alone is not enough to ensure fire-resisting performance.  Failure to install fire door products to the correct standards could compromise your contractual obligation and, more seriously, put property and lives at risk.

 The correct installation of the door assembly (door leaf, door frame, ironmongery and seals) is critical to ensure that the door set meets the required performance.  Document B also makes reference to BS 8214: Code of practice for Fire door assemblies with non-metallic leaves and this document details recommendation for the construction, installation and maintenance of fire-door assemblies. The use of incorrect glazing, ironmongery, leaf re-sizing, frame specification and intumescent products can easily invalidate fire test evidence, it is imperative that the Kelly Doors’ installation instructions are followed.  If any variations are required you must seek the opinion of Kelly Doors or Chiltern International Fire. Kelly Doors can supply fire-doors as complete pre-hung door sets, achieving the recommended gaps between door and frame and ensuring the fire-resistance of the assembly is not compromised by the on-site addition of hardware.  In addition Kelly Doors offer an installation service, by using our trained and Chiltern certified fitters you can be assured that all fire-doors are installed to the correct standard.

Yes, all fire doors should check on a 6-monthly basis to ensure that the components, ironmongery and fixings have not deteriorated.

Fire seals should be checked to ensure that they are still intact and complete.  Any missing or damaged sections should be replaced like for like immediately.  Seal should be fitted in accordance with the manufacturer’s instructions. The seals can be butt-jointed against each other, seal any cut edges with water-proof mastic.  Smoke seals should only be replaced in a continuous length and should not be butt-jointed. Timber doors may shrink and it is important to ensure that the gaps do not exceed 5mm.  In the event of a fire gaps greater than 5mm may cause premature degradation of the expanded in tumescent.  If the gap is greater than 5mm the in tumescent manufacturer should be contacted to determine if the seal is suitable for the gap size.  Gaps >5mm can be reduced by gluing (use a thermally resistant adhesive) a >/= 6mm timber strip of equal density timber to either the doorframe or the door edge.  It may be necessary to trim the door leaf in order to be able to apply a minimum of 6mm to the door or frame. The other extreme is that the door may have swollen due to moisture intake this may impede the opening/closing action of the door.  If this swelling is permanent the door should be trimmed to give a 4mm clearance. Off-square ness may be caused by loose fixings and this should be rectified immediately.

If the door leaf is damaged in any way it may require replacing or repair.  Damaged lipping and facings can result in a serious loss of fire integrity.  Any repairs should only be undertaken in consultation with Kelly Doors, as material and glue selection is paramount in achieving fire integrity. Glazing is the most fragile component of a fire door and is most likely to be damaged.  All glass replacement should be in consultation with Kelly Doors as we offer a wide variety of glass for the use in fire-doors and there are specific proprietary glazing systems to ensure fire integrity. The most common and cheapest type of glazing is 6mm Georgian wired glass, which is suitable for use in fire-doors up to 60mins.  It is the wires in this glass that provides the integrity by holding the glass together; therefore a crack in Georgian wired glass is not a fire risk.  However, if there are any small holes the glass should be replaced immediately. 

Any clear fire glass should be replaced immediately if damaged.  The aperture should be glazed temporarily with wired glass if the clear glass cannot be sourced immediately.  All in tumescent, fixings and beadings play a vital part in ensuring fire integrity and should all be replaced like for like.All ironmongery; hinges, latches, bolts, self-closing devices, automatic release mechanisms, handles, face-fixed plates and letter plates should all be inspected at 6-monthly intervals to ensure that they are intact, operational and not causing any damage to facings etc.
