Insulating a northern brick house
I am in Winnipeg, MB and have a Eaton’s catalog house (1917) with a wall detail of an outside course of brick/small airgap/brick. As a character house I don’t want to lose the exterior brick work. To get some kind of insulation i was going to frame in. I had figured 1inch EPS foam, then studs against that layer then fill the studs with XPS and seal the foam as a vapour barrier. I will be having to redo windows trim anyway so not a big concern on wall thickness. Would this be the right approach? i figured with the air gap between brick courses i wouldnt have to worry about the brick not being able to expel water from any potential condensation.
Not easy to figure out what to do this north in terms of insulation without a massive exterior layer of insulation that would kill any exterior character brick work.
