So I have a question about insulated exterior and interior render in a old Cornish granite based house.
I have been advised in order to up the EPC rating to get the place rendered with an insulating render - insulation board with a render over the top (I guess that's what it is) on the outside and inside.
My first question is this the right thing to do? I would have thought it would lock damp into the solid walls. Is there another way to achieve the same insulation with something that breathes naturally?
I hope someone can help?
