If the existing glazed door in question is suitable to be used as a fire resisting door, then the existing non-FR glass could most likely be replaced with a fire rated glazing system. But be sure to use, or at least consult, a competent specialist in regard to this work to ensure compliance.

First image: The smoke seal to the door bottom edge should extend as far as the full width of the door leaf. Ideally the vertical smoke seal would be fitted to the door frame (rather than the door leaf) and therefore would seal the gap you have highlighted. Mastic is unsuitable. Second image: That gap should be 4mm max in accordance with BS 8214: 2016 and the smoke seal fitted to the vertical edge of the door leaf or door frame should seal that gap when the door is closed. Mastic is unsuitable

According to Health Technical Memorandum 05-02: Firecode Guidance in support of functional provisions (Fire safety in the design of healthcare premises): Door closers Generally all fire doors should be fitted with an automatic self-closing device complying with BS EN 1154 or BS EN 1634-1, with the following exceptions: • fire doors to patients’ bedrooms in facilities providing in-patient mental health services; • fire doors to bedrooms in in-patient accommodation for people with learning disabilities; and • fire doors which are kept locked shut

Approved Document B to the Building Regulations only requires them as follows: Vision panels are needed where doors on escape routes sub-divide corridors, or where any doors are hung to swing both ways. Note also the provision in Approved Document M Access to and Use of buildings, concerning vision panels in doors across accessible corridors.

Hi, Are door closers required in rooms in a mental health hospital or is this something a fire risk assessment should specify?

Is it a legal requirement to have a vision panel in fire doors. A commercial multi occupied building with unit doors onto communal corridors which is a fire escape route - can they be solid or need vision panel?

Hi Neil, Thanks for looking over this, my concern is the very bottom between the start of the fire excluder and side of the door. I am concerned adding fire mastic sealant in that area ( I have highlighted with a circle) is not appropriate for fire safety? I have also highlighted an area with a rectangle shape, and querying if fire mastic should be added there, in regards to fire safety? If any more info needed, please let me know. Thank you Steph

I have a customer who wants a loft conversion. Hallway doors are original and 44mm solid wood. They have a glazed panel. Can that panel be replaced with fire regulated glass and still meet regulation

The inch/25mm rebate/stop harks back to before intumescent seals existed so as Neil says no need to make a frame up to that on a newer door set

It's a door that is required to resist fire and/or smoke for a defined period to protect the escape route and failure of that door could endanger relevant persons - it requires inspection, I fail to see why the authorities are unsure, it's very straightforward! Remember the quarterly checks are intended to be basic checks by the RP and not a specialist contractor so there should be no major cost implications, could be done whilst on site for an emergency light test visit

"Propose to fit new intumescent strip / smoke seal to an existing d30 fire door, if a gap of 4mm between frame and door is evident on one side of door viewed from inside.Is it necessary to remove door , architrave and increase frame or can you alternatively plant a new lining on the outside frame to increase the rebate to 25mm.( al so still fitting the strip / smoke seals ?) and will this method be Certified as acceptable practice". There appears to be an intumescent strip already fitted and if the door to frame gap is already 4mm, then it complies with BS 8214: 2016. Why not just fit a smoke seal to the push side on rebate stop? Why do you require a 25mm rebate? This is unnecessary. The products you purchase for this task should carry product certification.

Guest "Sas" (and anyone else who reads this) It is never a good idea on any forum to reply to an old post (Look at the date the post was made) 🤐 The reason is that you ask a question in good faith waiting for an answer, as you do not get an answer within a few days you think little of the forum you asked on, so you move on feeling sour,🤮 but as is often the case the original poster (The OP) has moved on before you asked the question, so the OP will never reply to you. In this case, Rob64 last posted in December 2024, he last visited January 5th 2025, 4 months before you dug up the post. 😔

Looking again at the photo, do you mean the hole or perhaps the gap under the door frame jamb? If so, these may be filled with suitable timber.

Hello Neil, Thank you for the feedback. Steph

Hi, I am looking at some steel flat fire doors in a high rise that have excessive perimeter gaps. I don't have the manufacturer's original specification. How can the gaps be reduced? Is the only option replacement?

Hi Everyone Looking for a viewpoint on the following if anyone can assist please. Threshold gaps to fire doors should obviously be kept to within permissable limits and if a door performs a smoke stopping function then 3mm is regarded as the accepted threshold gap. To reduce such gaps where threshold gaps are becoming excessive then an accepted practice would be to add a hardwood strip with a minimum of 6mm to the bottom of the door by glueing and screwing. Question: Is there a maximum size put on any timber hardwood addition to reduce a threshold gap at the bottom of a door? Thankyou for any help in this department.

Hardwood does have a degree of natural fire resistance due to it's density and it can be further treated to give more measurable fire resistance. Spare linen in a cupboard that opened onto the stair would be acceptable if there was a fire door on it - by extension if the sideboard was of suitable fire resistance and not an obstruction you could argue it would be OK - that's the point of risk assessment (That doesn't mean it would be accepted depending on the opinions of the individual fire safety inspecting officer).

The "certification" would most likely take the form of a letter or inspection report confirming compliance with BS 8214: 2016. A competent fire door repairer or inspector should be able to provide that service.

To comply with the current standard BS 8214: 2016 it would be necessary to reduce the door to frame gap to 4mm maximum and ensure that the threshold seal, when engaged, closes the threshold gap along its length. Mastic would be unsuitable for remediating this defect.

In the light of this information, I would suggest you contact the fire door inspector for the details of compliant letter plates. You would then be able to contact the letter plate supplier(s) for evidence of performance, price and availability. Then check compliance again with the fire door inspector before placing any orders.

Follow up post re cupboard housing 5x electric meters / 1 consumer unit) in communal area of Victorian conversion over 11m in height. Requirement is for annual inspection of doors to flats and quarterly inspection of “fire doors” in communal areas. There are no traditional fire doors in the communal areas (one single staircase) but there is a cupboard housing the electric meters. Is this classified as a “fire door” under 2022 regulation and requires quarterly testing? Spoken to FB and K&C Borough council and can’t get a definitive answer. Thank you. I can attach a picture of the electric cupboard doors which were retrofitted with inner fire protection several years ago, if this would help.

Hello Neil, Thanks for the reply, as requested please see image attached, the door looks in bad shape as repair work have been carried out to fix gaps,(still not fixed) and I have been recommended the gap between the drop down seal/fire excluder and door frame/jamb can be sealed by adding fireproof mastic at the bottom, due to its position I am querying if ok to do? Thanks, Steph

I dare sayBC will want a more detailed specification to achieve 60min REI than just another layer of plasterboard. For example, look at the British Gypsum White Book and it soon becomes clear that joist size, spacing, screw placement, plasterboard type and thickness etc, are essential components in any claim for fire resistance. Also be aware that there will be a need to consider sound attenuation. Probably cheaper to remove existing suspended ceiling and get an architect to specify.
