  1. 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.
  2. For FD30s doors, Building Regulations ADB require compliance with BS 8214:2016 in terms of the threshold gap.
  3. Tom, A door lining is another name for a door frame often with planted stops, instead of rebated from the solid.
  4. 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.
  5. https://fdis.co.uk/ and https://fdis.co.uk/contact-us/ should provide the answers you need.
  6. 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
  7. 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?
  8. 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.
  9. 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
  10. 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.
  11. 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.
  12. It would be better to engage the services of a Certificated Fire Door Inspector.
  13. 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.
  14. 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.
