I have 6 Identical large dinners; the latest building has FD30S double swing doors between the diner and kitchen the rest have FD60S. All were built to 2007 regs. The doors are now at the end of life, can I replace them with · The regulatory requirement is for a FD30 door to be installed. · An FD60 rated door (as installed in 5 of the diners) configure as an FD30 to provide a more robust solution. · All double doors are to installed with A back-check mechanism to stop the over extension of the hinge on opening. Automatic hold-open connected to the fire alarm system with a timed release so that the doors return to the closed position when the diner is unoccupied. · Door protection on both faces of the door to a height of 25mm above the height of the kitchen trollies. · The glazing with any associated beading shall not be installed within 25mm of the door protection. · Leading edge protection shall be installed.

It all depends where the door is located, if there is nothing within 1.8 metres and no door above it is doubtful that there is a requirement for the door be fire rated.

There is no requirement for third party accreditation for the door or installation (you can get Joe Bloggs to fit it), however, it may be prudent to do, so that you can prove that it was compliant at the time it installation.

You would need to interrogate the certificate for the construction of the door which will tell you what modification can be made to the door.

So long as there is no pressurisation present, the only statutory requirement is for head and jambs to resist the passage of cold smoke

the door should resist passages smoke to a given performance standard when pressurised from one side at “ambient” temperature to limit the amount of cold smoke passing from one side to the other. The requirements specifically exclude any performs for the threshold, the key point is that ADB only requires the head and jambs to have a performance form standard in respect to cold smoke leakage. When pressurisation is being used in a building as part of the active fire safety provisions then the requirement for smokes seals on the threshold of doors is increase and it is these conditions word threshold sealing would need to be considered So long as there is no pressurisation present, the only statutory requirement is for head and jambs to resist the passage of cold smoke

There is no requirement to fit intumescent packers on a FD30 door, however any packers fitted should be

Can you put an intumescent block in the hole

Under building regulations there is no leakage rate for smoke on the base of a door (head and jambs only)

Building regulations are not retrospective. If the inspector has failed the door purely because it is not to the latest standards then he it wrong

The addition of seals to the door is a modification to the door The door was designed and constructed to function without seals, by adding seals you have taken it away from the specification, either live with it or replace the doors. I would have thought that apart from cross corridors and stair wells there would not be many fire doors in the school

Its sleeping accommodation, I was hoping there was a percentage of failures that would mean that the regulations would tell me to replace all doors instead of making an induvial case to the building owners for each door. When you look after 1500 buildings with 45000 doors you need all the short cuts you get

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.
