Can anyone help? I have an integral garage, and the joining wall with the house is unrendered breeze block. I would like to insulate it and would like to know which is better, spray foam or something like celotex boards.
If Celotex boards then how do I fix them to the wall? Do I need to batten the wall first? I am trying not to lose too much of the width in the garage so spray foam seems good, but does it have the same thermal properties as the Celotex?
Any advice would be welcome.
