i use 50mm kingspan fixed on with Everbuild Pink grip dry fix foam, then with plasterboard fixed with same foam. All joins on insulated board sealed with insulation tape to help stop moisture getting through.
You can also mechanically fix (some say to do this in case of fire ... but I don't bother - if a fire is so hot they melt, then the room will need redoing anyway! - makes sense in corridors in flats etc for access).

You can use any thickness board, the thicker, the warmer. But some people say that if you put too much insulation on internal walls, the stone walls get too cold and you will get problems with more damp / moisture in the walls - the idea is that it is not perfect, some heat still gets through as old walls "designed" to breath etc.

Here's the pics, was a full refurb. Removal of chimney, insulating under floors, rewiring electrics etc. First time doing something like this for me (my background is office work!).

Wow that room looks amazing - wish mine looked like that.
So am I right in thinking Kingspan then plasterboard. Obviously the walls would have to be plastered on top of boards again wouldnt they. So would you suggest a 50mm board would be enough? Also what would the thickness be of all the extra so thats kingspan and plasterboard. Just wondering how much I am going to lose of an already quite small room.

well, it's only the outside wall/s you need to do. You will lost < 65mm - 50mm kingspan, some foam, 9.5mm plasterboard, some more foam, plaster skim about 2mm?

Tears would add to the condensation.

Deal with the cause, not the symptoms.

Insulate, check your heating patterns, and deal what is producing the moisture - include extracting at source in the kitchen and bathroom.

If all this fails, consider fitting a positive pressure fan - Drimaster or similar.

You still haven't said what windows you have

Take any existing plaster back to brick. then look at celotex PL4000

...or you could insulate with lime-hemp or lime cork plaster - expensive unless you do it yourself

Sorry have double glazed windows - the ones without the air vents unfortunately.

Thanks for all your advice - really appreciate it.

No doubt in my mind its condensation. Insulation is the solution, I am sure it will make an enormous difference. I also live in an old stone house with 24 inch walls and did insulate upstairs when I moved in and the walls are just as they would be in a modern house. Seriously regret not doing the same downstairs, would do it in a heartbeat but my wife will not allow it. Too much disruption, nowhere to put furniture etc.

I think you should employ a glazer or builder to retrofit trickle vents into the windows. That is essential and I'm shocked that nobody here has mentioned it other than me. It's the first thing you should do before any other work.

Lol. Clueless.

Trickles will make little difference. The OP need only crack a window to discover that. Insulation will make the greatest difference to any cold surface related issues.

I'm shocked you are even commenting on building work.

Mike when we bought house many many years ago we built a new bathroom/kitchen extension and that part of the house is cosy as walls were insulated just wish we had had the sense to insulate other walls. Would have made life far easier. Looks like we are going down the route of insulating boards.

Many thanks for comments and advice. We have decided to use insulating boards (not till after Christmas though

Hope you all have a great Christmas and New Year.
Thanks

Disagree, moisture will dissipate with better airflow.

Better than what? The difference will be marginal and won't prevent cold surface related issues which the OP has. They are better off spending their money on insulation rather than butchering the windows. As I said, for what its worth, they may as well crack open a window.
