Insulating Exterior Brick Wall in Bathroom
Hello and Thank you in advance,
I started demo on my first floor bathroom of my 1965 Zone 5 (Northwest NJ) House today. Behind the tile of the alcove for the tub I found a sad display or furig strips and thin polystyrene and a vapor barrier. There’s also a hole in there that yellow jackets had been living in. I’d noticed their entry hole from the outside in the summer and thankfully eradicated them.
Before I install a new tub and hang kerdi board and tile I would like to insulate the wall better.
I’m thinking poly iso sheets between some fresh reorganized furling strips and sealing with expanding foam all around. The poly iso would only be as thick as the furling strips so then I was thinking a vapor barrier over that. Followed then by kerdi board and ultimately tiling.
Does this make sense or do I need to frame out, lose some of the bathroom space and do something more expansive?
