I need to change all my existing internal doors with FD30 fire rated doors. I need traditional looking doors in keeping with the property.

They all seem to state that a maximum of 6mm can be trimmed off the top and bottom before you void the warranty and potentially void the fire rating.

The doors seem to be 1981mm in height only but I need a few to be 1950mm and one that needs to be 1920mm!

You can get bespoke doors made but they will not only cost a fortune but also only come in modern designs not traditional.

Any suggestions?

Make the door frame bigger ???

Speak to a joinery company who also make / alter doors it - or speak to a specialist door company who make their own as then will warranty them.

you can trim as much as you want of a fire door as it is fire rated through the whole door,you will have to fix the door edgings back on with the appropriate rebates to take any intumescent strip but this is usually on the door frame anyway,you only put it on the meeting stiles of double doors,we get 1220x2440 fire doors at work and we cut them to size and edge up as we do a lot of oversize doors and double doors

Ding, speak to the door seller and state the problem. Let's see what they say. Needless to say that if they agree for you to trim more than 6mm, you obtain that agreement in writing.

If they don't budge, altering the frames is an option, as shytorque suggests. Getting a custom made ones made with warrantee is another option, as Paul suggests, but you've already said that this is going to cost a fortune. You may have to go for getting them made, if nothing else.

You can go ahead and trim them, and void that warrantee.

Just pay for the custom ones even though they are expensive. We all know that is what you are going to do and how you are going to tell us all about it

Thanks Swati.

Paul, I haven't tried a joiners etc but I'm assuming it will cost a lot and I'm trying to find a cost effective solution.

Scooby 1994, what do you mean by 'need to fix the door edgings back on'? I'm not that bothered by the warranty tbh, I'm concerned that some uptight building control officer will not sign my building works off because he feels the fire rating has been compromised.

These are the doors I'm after. Do you think I can trim off as much as I need to without any issues? Thanks.

Dingdongler

Sorry mate, these are the doors!

I've just had the head of South Wales fire out to one of our properties which falls under HMO.

The current doors that are there are like yours and all to **** on sizes. The ones that were very odd sized and I couldn't get away with keeping I changed the frames on. The ones I didn't have to change the frames we cut the doors and by more than a few mm. As said above a fire door is rated 30/60/90 etc through the entirety of the door so cutting one is not usually a problem ( done it many times personally in many different properties of ours which fall under HMO )

The fire Marshall and the councils HMO department have both passes them and was more than happy with what and how we achieved it. I was lucky as the doors there on the ground floor were solid oak so we routed the doors and added the intumescent strips and cold seal to the doors and they were checked off.

You can have up to an inch from the bottom of your door to the floor gap as well if you didn't know. Reason being is smoke rises and before the room got to the point of it belting out smoke and flames from below the door, then the room at that point will be an inferno.

I also had to change glass panes throughout the final exit routes to pyro glass so it complied with the FD30 they placed upon the route.

At the risk of pointing out the obvious, have you tried doing exactly what it says on the supplier's website and spoken to one of their Door Experts "for further information regarding the trimming of fire doors"?

Dingdongler

Thanks mate, that is very helpful. Scooby 1994 has pmed me and stated similar to you.

Btw, in what capacity do you deal with HMOs?

Cheers

Dingdongler

Yes I did. They are not very helpful, they just repeat the sentence 'trimming off more than 6mm will void the warranty and MAY compromise fire rating'

If you ask for details they just repeat the same sentence over and over.

However it seems on good advice from SN members that the latter is not true.

I run domiciliary care homes, they fall under normal tenancies. The houses are of 3 or more people of different families so it falls under HMO regulations.

Don't know if you know this but it's recently been made mandatory that sprinkler systems be fitted as part of certain HMO categories, mine is one of the buggers so that's gonna be something new to tackle

Can you not just paint the existing doors with Timonox fire retarding paint?
Or do you have to have intumescent strips fitted too?

Dingdongler

I need intumescent strips regardless as the stoppers won't meet regs. The problem is there are some thin panels on the door which would need 'reinforcing' with some kind of fire retardant card, the paint alone won't suffice on the sections with these thin panels.

Seemed like a lot of hassle and I don't know how they'd end up looking.

zip106

Ah ok.

Timonox looks $hit anyway ....
