A bare shell is an opportunity to dry-line and incorporate as much
insulation as you can afford. Check out thermal conductivity; stone 1.3
to 2.3 W/mK, foam 0.02 to 0.035W/mK. So 50mm thick foam can be better
insulation than an astonishing 5 metres of stone. Stone buildings are
cool in summer and freezing in winter!

Stone buildings remain the temperature of the stone, which you can
alter with a lot of expence. So if you get your stone walls wharm in
winter, the house will remain wharm for a couple of days with the
heating off. But it takes 7 days to get the house wharm when it was
cold.
I am puting 120mm of kingspan on all my stone walls, except the ones
when I want to see stone.
Best to have the insulation on the outside of the walls so the thermal
mass
is usable.
I didn't see the original post. I have a flint wall barn with thick walls.
Flint
is a good conductor. We had an additional block wall built inside the
existing wall with a good layer of insulation in the cavity. The result is a
very
low rate of heat, judged by the bills and the size of the house. It is warm
in
winter and cool in summer.

Thats what I have done, but as I don't have windows in yet, I have no
isea if its gonna work - I have new confidence now.
