Can i replace 44mm internal doors with 35mm doors?

Anonymous user 28/02/2024 - 2.59 PM

I am looking at replacing 7 internal doors and although the doors we have at the moment are not fire doors they are 45mm thick. I am looking at replacing the bedroom doors with fire doors which are 44mm so no problems there but for the remaining doors really just want to buy the standard 35mm doors. Will this be possible or will it cause any issues with the current door frames?

Are you a tradesperson and able to answer this question?

Not really a big problem, to get a good finish you would just need to move the door jamb in a bit so there's no gaps when the door is shut. Sometimes the door jamb is integral to the frame in which case the easiest solution would be to add a 10mm bead to them.

Not a problem at all, I have encountered this many times, you just need to replace the door stop as well, or reuse the existing if you can get it off in one piece. The lock keep will obviously need relocating, but apart from that, it is a relatively straightforward job.

It’s dependent on if the frame’s/linings/casing are rebated or have a stop lath, if there stop lath you can fit the door and move the stop lath up to the door, if there rebated you could fit laths on top of the rebate but would look unsightly, and usually if your internal doors are 44-45mm that means they may be fire doors which would be worth looking into as could void insurance or go against regulations if the property is rented out.

Yes the guys are right it can be done.but make sure that you keep fire doors were regulations are such.As your insurance company might not pay out in case of a fire etc.Also if it is a fire door the frame will be all the one with no linings.So i think it might stand out a bit!!! Hope this helps Trevor

Agree with all comments here though I think one meant 'stop' instead of 'jamb'. You might find the smaller hinges leave a gap where the old ones were. Good point about checking regs for your insurance.

Like everyone else is saying it would be possible if you can easily move the slamming strips

Not a massive problem to get the best finish, I’d move the slamming strip and the keep on the frame to suit the new door

Not a big deal, simply can do anything with wood, in this case relocating door stop would be just fine, or adding 10mm wood strips on door stops.

That won’t be a problem at all you can either take the doorstops off and move to suit the door or if they are all in one with the frame and architrave like some I’ve come across you can add a plant of timber around the door stops say 8-10mm to suit. There’s always a solution somewhere again if you prefer remove old stops and get bigger size to cover old. Only thing is to check fire regs but as bedroom ones are still fire doors can’t see it being a problem.

Not a problem at all, you have two options. 1 would be to fit 10mm infill strip to the door frame on the top lat or rebate (would be the only way if the door frame is a rebate casing) or 2 you can simply move the stop lat to suit
