If the doors need to be fire resisting doors but are of a non-standard size or shape, then you will need to buy custom made fire doors and door frames.

There is no mandatory requirement in terms of the Regulatory Reform (Fire Safety) Order 2005 for existing emergency exit / panic escape hardware to be CE or UKCA marked. However, Article 17 of the Order requires that they are maintained in good repair and in efficient working order.

Nominal fire doors can only ever be existing doors already installed in a building - one would never install a nominal fire door. Any new fire door that you purchase to install at the holiday property will have documentary evidence of fire performance. Therefore the door must be installed in accordance with the manufacturers certification. The frames and handles may be reused provided that they comply with the specification in the manufacturers certification, including where the door frame reverse face meets the surrounding wall construction.

Misalignment of the door leaf and door frame is a common issue. In terms of requirement of the installation to comply with product certification the door leaf must not stand proud of the door frame or if this is permitted there will be a very tight allowance, typically 1mm. As far as the door leaf being "off" the rebate stop, I have not yet encountered a limit for this issue and recommend where the stop is the planted type that it be moved to compensate for any twist in the door. For a frame with a rebate machined from the solid this would not be possible of course. To be correct, one should always check with the particular door manufacturer to see what is permitted in terms of tolerance for the door leaf to stop dimension.

So long as the specification of the existing door frame meets the requirements for the new door leaf, then yes. So you need to obtain the product data sheet for the new leaf and check that the existing frame meets the requirements therein.

Or if you do want to persevere with a timber door, try Strebord or Strecore here https://falcon-timber.com/downloads/

One more that could be worth a try. This guy knows his stuff https://www.solarwindows.co.uk/team/3/john-lewis

Be sure to check the technical manual for the timber fire door core or installation data sheet for a timber fire door leaf. That document will advise which ironmongery is permitted.

If that won't work because the door leaf closing edge is eased at the corner, you could use these instead:

Use flat intumescent strips (fire-only) but with batwing seals to deal with restricted smoke spread.

Yes, I agree its an issue for me too. I have some evidence of fire resistance performance for a cylinder rim night latch and it refers to fire resistance performance tests. In terms of compatibility, I would only install one where I can be certain the type of door is covered by the available test evidence including intumescent protection and location of the device. Even then I wouldn't recommend one due to issues with the self-closer often failing to overcome the resistance from the latch strike.

The building may have changed. "On the day" is important.

It would appear that the doors you describe are most likely not fire resisting doors. Has a fire risk assessment been carried out? Are these doors considered adequate for the purposes of fire protection?

Its not the installers job to advise exactly where fire doors are required, that is a job for the Fire Risk Assessor. There should be a Fire Risk Assessment document for the building. Consult that document for information and if there's no relevant information there discuss this with the Fire Risk Assessor via your client.

This looks like an edge seal of intumescent material. FD120 doors require a greater amount of intumescent edge sealing than lower rated fire doors. Is there any mark, label or plug on the door enabling traceability to the door manufacturer? If so it should be possible to answer your question by consulting them.

You will find that third party certificated fire door leaves specify that CE or UKCA hinges to BSEN1935 are a requirement and often certificated too. Doors fabricated from fire door blanks don't always specify TPC but might require CE or UKCA marking. Building Regulations Approved Document B (appendix C) requires hinges to have a minimum melting point of 800 deg C. https://www.gov.uk/government/publications/fire-safety-approved-document-b

From your comments I am unsure whether you are referring to the hardwood door lipping or the intumescent strip? The hardwood lipping should be prized away from the door leaf only by just enough so that Cascamite adhesive can be applied to the surfaces that are to be mated. Then use small panel pins to secure the lipping whilst the adhesive dries. You can then either remove the pins afterwards or you can bury the head of the pins into the hardwood lipping and fill over the heads. A loose intumescent strip can be secured to the edge of the door or the door frame reveal using small panel pins. https://www.ifsa.org.uk/

The slight damage near the mortice lock faceplate can be easily repaired, just as you would with a normal timber door. As you say, adjust the door position in its frame to achieve the 2mm to 4mm gaps.

Contact a suitably experienced and competent fire door inspector. They would be sufficiently confident in their decisions and be able to support their decisions with evidence or, in the case of a nominal or notional door, with valid reasoning.

Not a requirement but may be used. Looks much smarter when they are. The lock or latch must be suitable for the particular type of fire door in question.

Roller bolt type latches are not usually fitted to fire doors. Section 6 of the document 'Code of Practice: Hardware for Fire & Escape Doors' deals with latches and the many fire door related issues concerned with the different types. The document is available online at http://firecode.org.uk/Code_of_Practice_hardware_for_fire_and_escape_doors.pdf Below is particular commentary on Roller Bolt Latches

Hi Richard, This is a common problem, installers don't always realise that fire doors have strict trim allowances. If the door has already been trimmed to its max, there's little point in trimming it further just to add timber back again. If you can find a certification label on the door, that enables you to contact the door manufacturer for specific advice. We provide various types of fire door related training but not specifically Responsible Person training for fire safety generally. https://www.firedoorscomplete.com/
