We are looking at installing IWI in our detached brick built victorian house. I have been told 2 sets of conflicting advice. Remedial surveyor suggests using stud work (as opposed to dot and dab) and installing a membrane (of the egg carton type stuff used to tank cellars) in between the wall and insulation. But conventional wisdom suggests this would limit the breathability. I'm also concerned about the 'thermal mass' issue. Has anyone any experience with installing IWI on an old building, how has the brickwork faired? And I'd so how did you do it? Should I consider using a membrane? The remedial surveyor also suggested using the membrane on the chimney breasts to prevent the salts leaching out into the plaster.
Thanks in advance!
