Older solid brick building insulation
I'm currently remodeling my kitchen which has one 2-wythe outside wall(about 18 feet long, 8 feet high). This is in Boston area. The wall previously haphazrdly covered(maybe 7-10 years ago) with some 1" foil backed fiberglass stuff, but it doesn't look like it caused any damage.
I have thoroughly studied building science corp materials, NPS preservation briefs and other materials on the subject of insulating older masonry walls. Sprayed foam is not an option, so it leaves me with two possibilities:
1) XPS panels glued to the wall, then a layer of sheetrock over metal studs. Since the room above is not being remodeled, it won't receive any insulation at this time. So no matter how well i fill all the haps, an unknown amount of interior air might leak from the top. Or is this not a concern since the air will just rise?
Another concern is that the wall is somewhat irregular and the foam panels will not be 100% flush with the wall.
2) Leave the wall as is - without any insulation and focus on air sealing. I'm really leaning toward this solution as I really don't want to cause any damage to already old masonry. So in this case I will just build a metal stud wall in front o the brick wall and cover it with sheetrock. Does that sound reasonable?
I will apreciate and comments/feedbacks on my ideas.
