Generally yes, OK to add hardwood lipping but not added to the existing lipping. Cut off the existing lipping and replace with a thicker one. Hardwood lipping should be minimum 6mm thick and maximum 18mm thick. Generally, the door frame rebate stop should be 12mm or more and intumescent fire seals are necessary. Updating your fire risk assessment will help in identifying which doors need to be fire doors.

The Fire Risk Assessment for the building should identify requirements for fire resisting doors and escape doors. https://www.gov.uk/government/publications/fire-safety-risk-assessment-offices-and-shops and https://www.asdma.com/knowledge-centre/#six may be useful

Fire doors and escape doors are fire safety devices and assuming you are in England or Wales the requirements of Article 17 of the Regulatory Reform (Fire Safety) Order 2005 must be met http://www.legislation.gov.uk/uksi/2005/1541/article/17/made If your fire doors are in good order, as you say they are, then its reasonable to expect they comply with the legal requirements. With regard to perimeter gaps, these should be between 2mm and 4mm. With regard to fire door-set (rather than fire door assembly) and certification labels, these are not legal requirements. On the subject of fire safety, I would recommend that you seek advice only from 'suitably competent persons'.

All fire door blanks have a Technical Manual or Global Fire Resistance Assessment. Consult the manufacturer to obtain the documentation and follow the information therein. Different types of fire door blanks have different sizing, cutting and lipping requirements.

The reference PLY INT FD 838 P would indicate that an 838mm x 1981mm fire door has been installed but the installation must be compliant and it would appear there are doubts that it is. I would recommend that you contact your landlord and suggest engaging an independent fire door inspector to check compliance.

So if restricted cold smoke spread is not a requirement for your design, FD30 doors may be used instead of FD30s doors. Many FD30 doors permit a 10mm gap at the threshold, check with the particular fire door manufacturer.

For FD30s doors, Building Regulations ADB require compliance with BS 8214:2016 in terms of the threshold gap.

Tom, A door lining is another name for a door frame often with planted stops, instead of rebated from the solid.

If the door leaf is new with installation instructions or an existing door leaf with a manufacturers label, you can check to find out the door frame sectional size and material requirements, hinge and hinge position requirements, intumescent seal requirements, fixing requirements (these should also be contained within the door frame kit) and fire stopping requirements. Smoke seals may likely be required too.

https://fdis.co.uk/ and https://fdis.co.uk/contact-us/ should provide the answers you need.

Try searching the internet for 'Fire Door Training'.

There are guidance documents for various types of building such as at https://www.gov.uk/workplace-fire-safety-your-responsibilities/fire-risk-assessments and https://www.gov.uk/government/publications/fire-safety-risk-assessment-sleeping-accommodation and https://www.gov.uk/government/publications/fire-safety-risk-assessment-factories-and-warehouses but where you are unsure you should consult a 'competent person' as referenced in the Fire Safety Order http://www.legislation.gov.uk/uksi/2005/1541/article/18/made

But the fire door may be suitable for use in a metal frame. What evidence is there that it isn't? Do the doors carry any markings at all, on the top edge or hanging edge perhaps?

There are timber based FD30 doors with fire performance test evidence when installed into metallic frames. You need to get hold of the door leaf manufacturer with regard to frame, hinge and intumescent seal requirements etc.

Hi Callum, Quite often buildings have doors designated as fire resisting doors when actually if they were to carry out a suitable fire risk assessment they would find that not so many doors need to be fire doors. A huge amount of money can be spent keeping fire doors in good working order, so its important to understand why they need to be fire resisting doors. Feel free to use content from my fire door blogs at www.firedoorscomplete.com

Composite fire resisting doors are required to be tested to the same standard as timber based fire doors, BS 476 part 22 and/or BS EN 1634-1. If the composite fire doors are new and you have a doubt about the installation contact the manufacturer for the product data sheet including installation instructions. Common faults, in my experience, are incorrect fixing positions (of fixing screws door-set to wall), inadequate fire stopping (BS 8214:2016) and excessive door leaf to frame gaps. Use of the correct intumescent gaskets to lock-sets, door-viewers and hinges is very important in regard to these types of fire door too.

The hinges for an 'existing' fire door need to be made from a suitable material with a high melting point, be of suitable dimensions, have the correct screw fixings, be of suitable durability (for such a door leaf) and be in good serviceable condition. You wouldn't necessarily change a hinge solely because it is not to the latest standard.

It would be better to engage the services of a Certificated Fire Door Inspector.

The Regulatory Reform (Fire Safety) Order 2005 applies to the buildings such as blocks of flats. Flat entrance doors are required to be fire resisting and therefore should be suitable for that purpose including having the correct hardware components.

Ask for a copy of the fire door inspection report. If the inspection has been carried out correctly, the report should detail all non-compliances separately for each door and describe the remedial works required. It could be that the door leaf to frame and door leaf to threshold perimeter gaps are incorrect.

Agreed. So long as the door leaf self-closes completely to the door stop and sits inside the door frame reveal, and the smoke seals are effective, then from a fire and smoke spread point of view the small gaps would be acceptable.

I would advise you to contact a Certificated Fire Door Inspector. A competent inspector would be able to come to site and inspect the fire doors and then recommend the exact method for the remedial works. There are a few methods that may be employed to reduce the perimeter gaps to within the necessary tolerances. They would also be able to provide the details you require in their inspection report. Once the works have been completed they could provide a second report and, if the door is by then compliant, to confirm compliance. Clearly though, where the inspector's inspection reveals any other issues, these would also require remedial works.
