A bare shell is an opportunity to dry-line and incorporate as much

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.
