Minnesota basement remodel: Insulation questions
I am doing a basement remodel and am looking to upgrade the basement energy efficiency on this 1976 rambler as much as possible. Any suggestions are appreciated.
Added oversized gutters with raindrop gutter guards to move bulk water far away from the house.
Inspect existing sump pump system to verify continuous drain to the sump.
There is a sign of water in the past in one corner of the foundation, but I have not seen water there since I moved in in 2012.
-Add 2″ of XPS foam T&G glued to directly to concrete
-Add 2″ of XPS foam T&G glued to the floor
-3″ of medium density spray foam (R18) for rim joists
-Add 1/2″ T&G plywood glued to foam, screwed if necessary
-1-5/8″ steel studs for exterior walls with rock wool insulation between studs
I would like to start on adding the wall foam board in the very near future. Is there any downside to doing the walls first, then the floor?
