Hi Everyone
This is the first of probably many future questions on a project I have going on here in France.
I am taking down an old French farmhouse over here that is pretty knackered and create a new house on a larger footprint.
Our major demands it must be clad in the traditional sandstone random stonework to blend in.
My question is which has the greater insulatory properties:
A conventional cavity wall with 50mm of polystyrene or 300mm aireated concrete block with no cavity.
The clading will be 200mm thick.
Cheers
Frank
