Fire Doors and Accessories

I am a mechanical design engineer and was wondering what is the maximum distance a fire door can be undercut by. I have contacted building control and have been informed that this is 4mm, but have been told by other engineers that they have previously been told that it is 20mm. Please could you confirm the actual dimension as i do not seem to be able to find anything with the Building Regulations either.

Hi if a school was built in 1980's and the fire doors do not have intumescent strips do we have to fit them to the existing doors to meets reg's now.

I have recently moved into a new home which I am decorating and have realised that the doors are the original old doors but have a layer of MDF/ chipboard over them. I was wondering if this would have been done by the previous owner for fire safety? And if I am required to keep them as is as I would love to be able to return them to their original state.

Hi, I own a flat in a purpose built block, with a total of 6 other flats. Recently we had a fire safety assessment which pointed out a problem with the Glazing in the front door on several properties. The building is about 28 years old, all of the flat doors are std hardwood entrance doors with 9 small glass panels in the upper half. Aparantly when they were built there was a secondary fire retardant glazing panel fitted inside, this is no longer there and therefore the recommendation is to retrofit for 30min safety. my question is what exactly do I need and where can I buy the materials Required. I’m fully capable to do the work but need to be certain th…

We are about to have a couple of 35mm FD30 doors fitted. By virtue of its size I guess its ok to have 3*3inch hinges(fire rated)fitted as opposed to the 4in hinges for 44mm doors please?

Hi all, I need some help please, can a fire door have a lip cut at the top of the door for the instalation of a concealed door closer so as the arm does not bind on the door?The closer part is fitted to the underside of the door frame and arm is fixed to the top of the door, i hope this makes sence Thanks

What is the recommended gap for a notional FD30S timber doorset at the door to floor, there are fire and smoke seal on the leading edge,top and hinge side but nothing at the bottom. The gap at the bottom is 12mm, what is the regulation on this type of door.

Hi, On a new install of a FD30 door set, would you expect intumescent packers to be fitted on the hinges? FD60 i would say yes, however on a FD30 i'm unsure, and all the information i can find states refer to the manufactors instruction. Any help would be useful. Thanks

I'd like some advise on whether screwing a door sign into a fire door stops it being functioning fire door. Please advise. Thanks a lot for your help, Angharad

We have a fire door survey contract in place and majority of the doors are composites. The building are sheltered housing, shared housing , high rise buildings. The client holds certification on some sites for composites but majority they don’t hold any evidence of certification. With the MOH detailing on GRP composites test data where several composite doors manufactures failed, i wounded where we stand if the client can’t provide any certification and is there any guidance on this matter.

The double leaf fire doors to the services cupboard in the communal corridor of a residential block of flats displays the mandatory blue "Fire door keep locked". Both door leaves are fitted with concealed door closers. One leaf is secured using a top and bottom door bolt fitted inside the cupboard, and the other leaf is secured to its mate with a FB mortice lock. Residents need to access the cupboard to read their gas meter and access the water stopcocks. The FB key to unlock the door is made available in an unsecured lockbox located adjacent to the services cupboard. The security of any door secured with a FB lock is illusionary given the keys are availa…

Good afternoon Could you please advise on the following: A Firedoor/set can be made by any joinery company using a fire door blanks(certified with Global Assessment)providing that the door is manufactured in strict accordance with the Global Assessment. They do not have by law to belong to either the BWF or TRADA "Q" mark to do this Bill

I've recently purchased a townhouse which is split over 4 floors (ground floor, 1st floor, 2nd floor and a loft conversion). The building survey has recommended that fire doors are installed in the property (it looks as though the previous owner had these removed at some point and installed with cheaper doors) which we're looking in to at the moment. The survey has recommended that FD60 fire doors are installed but when trying to scout out our door options, these seem to be more common in commercial properties. Would FD30 fire doors be sufficient?

I am hoping that you can assist.I am a building manager in a commercial property, which was constructed in 2003.The building had FD60 fire doors installed at the time of constrution, which complied with all the then regulations.Site recently had a fire door survey carried out, and the report stated that all the fire doors should be replaced to the current regulations.My question is, as the fire doors were compliant in 2003, is there a legal requirement to replace all the doors, to current regulations?

I am currently scoping a lifecycle project to replace some defective/none conforming fire doors. At the moment I'm up to 23 (59%) of the doors failing inspection, at what point should I just call it a day and replace all the of the doors in the building. To make matters worse it is grade 2 listed.

I have just moved into a new build house. The integral garage door does not close properly and is draughty from all sides of the door . Is this a fire and car fume hazard?

Wondering if any of the experts on this forum can help with a question linked to the specification/design of a new mechanism. I'm unsure if the requirements for a successful fire test of a door handle/latch mechanism require that the mechanism still works at the end? By that i appreciate the latch must keep the door closed but should it be possible to still open the latch from tested side - I assume perhaps not but wasn't 100% hence the question. Tied into this query is material choice, does the door handle/mechanism on the test side have to be non-combustible? Or is ok to melt as long as the door remains closed (Actual latch material doesn't melt, continues to …

1) My existing Flat Entrance door is 60 minute fire rated but, I would like to know if the doors within the Flat require to be fire rated (i.e Kitchen door, gas cupboard door, etc.) 2) Can you refer me to any Legislation? (I live in Scotland)

Hi Folks, I've recently had a 30 minute fire door installed in my flat. Does this need a special intumescent varnish on top of it, or will a normal varnish do as the door is already fire rated? My concern is that putting the wrong varnish on my actually make the door more flammable and counteract it being a fire door. Cheers, Tom

Evening All, I have been handed a job to route out a riser cupboard door and fit a intumescent brush seal, however there is an intumescent seal built into the frame. I was led to believe when I did my fire door training that you cannot have both. Is this correct or should I just remove seal in the frame and replace with intumescent brush seal. Look forward to replies.

Hi. I own an apartment in a block of flats that is accessed via an external balcony. I replaced the front with a standard UPVC double-glazed unit. However the management company have stated that it must be an FD30S fire door. Various glaziers have told me that this type of fire door is typically used internally, not externally. In your experience, please can you confirm if this is also your general understanding. I'm aware that you are not in a position to comment on this specific case but I would value your opinion. Many thanks, Jonathan

Hi Can you increase the width of an old fire door by adding a hard wood lipping to close up gaps? is that legal?

Hello advice on closers please, got a council building, 3 floors high, each with lots of offices as you can imagine being a council, each corridor has fire doors on self closers at each end, however, the corridors themselves have about 6 offices in each corridor, the doors to each office are approx 45mm thick, got 3 hinges and have brown strips in them, although no badges saying Fire Door Keep Shut, Should ALL these doors have a self closer or are the ones at entrance / exit from corridor enough ? Thanks

I own a 2 storey maisonette over a seperate flat below. Each of us has our own separate entrance . Leading from my front door is the stairs to my accommodation. I have fire doors throughout, fitted by the previous owner but wondered if it is possible to fit a fire door either at the bottom or preferably the top of the stairs,the stairs come up the middle with rooms either side ,as Im always concerned about visitors falling if unsure or the layout.

Hi, The client has a nominal door & half leaf FD30(S) installed into a timber framed glazed panel system approx 3m X 3m. There is no information on the construction of the door set or glazed system although the glazed panels do display kite marks. The timber framed glazed system is in a good condition. The client wishes to replace the leaf and half door set only and install a new set into the timber glazed panel system. What are your thoughts on this? I.e new door set into existing glazed timber panel system. Also the client wishes the new door set to be double swing but underfloor heating is installed and concealed floor mounted closing devices are the…
