  1. Refer to BS 8214: 2016 Timber-based Fire Door Assemblies - Code of practice. This guidance documents states that gaps should be 2mm min to 4mm max for optimum fire resistance performance. You don't say whether these doors require smoke protection, in which case this type of seal may provide a solution. Unsealed contact of the door leaf with the rebate stop of the door frame is insufficient in terms of optimum fire performance and restricted smoke spread.
  2. Yes it can but you need to repair the door and frame, back to its factory state, before you install. Make sure the door leaf is solid core, not Tubeboard or panelled.
  3. The door hardware needs to be compatible with the fire door leaf but not always necessarilly fire rated. Check the available evidence of fire performance for the door leaf for the hardware specification.
  4. If you require an FD30 door there's no problem using a 54mm thick (potentialy FD60) door leaf. If single leaf door, the seals should usually be central. Can't say more without seeing the door in the flesh.
  5. Surely the floor of the garage is at a level considerably lower than the bottom edge of the door and I would expect the door frame to already have a flush cill? If you can identify the fire door to it's manufacturer or it's certification you will be able to find out the requirements for the threshold and Section 12.3 of BS 8214: 2016 Timber-based Fire Door assemblies - Code of Practice provides guidance about smoke sealing at the threshold.
  6. See Approved Document B for the current building regulations at https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1124733/Approved_Document_B__fire_safety__volume_1_-_Dwellings__2019_edition_incorporating_2020_and_2022_amendments.pdf Table C1 Page 139 It seems the question would be 'does your conservatory form part of the house?'
  7. That depends what the certification data sheet or other fire performance related documentation requires. Is any available?
  8. FDIS have a code of conduct. You will likely have your inspection criteria?
  9. If the door leaf can be identified to the manufacturer or it's fire resistance performance certification it should be possible to check the lock requirements. Maybe the door leaf has been over-morticed at the keyhole and lock-case? Surprised at the use of spring hinges on such a critical fire door, usually a controlled self-closer would be used meeting the requirements of EN1154 minimum power size 3 . At the very least, I would check that the door self-closes reliably to the door frame rebate stop completely from any opening position in a safe and controlled closing action.
  10. 1) Contact the door leaf manufacturer for advice. 2) How critical is the fire door to life safety? Would replacement provide an improvement commensurate with risk? 3) Are there alternatives to replacement in mitigating the risks around the non-compliance issue? (given that the door will need to be repaired to accept a smaller lock)
  11. Astra installation video https://www.google.com/search?q=astra+3003+installation+manual&rlz=1C1GCEA_enGB952GB952&oq=astra+3003+installation+&aqs=chrome.1.69i57j33i160l3.12004j0j7&sourceid=chrome&ie=UTF-8#fpstate=ive&vld=cid:86d85776,vid:mdAPp0WP0tI Fire test report to EN 1634 gives installation position data http://www.astradoorcontrols.com/products/3000-series/
  12. Todays fire regulations are https://www.legislation.gov.uk/uksi/2005/1541/contents/made Contact DHF for more information about metal fire doors https://www.dhfonline.org.uk/pg/metal-doorsets/346.htm and https://www.dhfonline.org.uk/pg/regular-door-maintenance-requirements/483.htm
  13. Possibly. Do you have a picture?
  14. Start with the Responsible Person at the building. They should be aware of the fire strategy, by taking advice from a competent Fire Risk Assessor where necessary, which doors need to be fire rated and which of those should provide restricted cold smoke spread. Naturally, some doors will be more critical to fire safety than others and the RP should be aware of this. If they are not aware they should seek advice from a Competent Person.
  15. Some, not all, timber fire door leaves have evidence of fire resistance performance for use in metal frames. Do you have reason to believe the doors are unsuitable? and how critical are the doors to the fire strategy at the building? are the sort of questions you should ask. If you have concerns over the safety of the doors you could contact a professional fire door inspector at https://afdi.org.uk/category/find-a-fire-door-inspector/ for advice.
