Insulating Steel Columns in a Basement
I am starting a project to frame and finish my basement with 2×4, 2″ XPS foam board in zone 5. I am trying to plan on how I will insulate the support I-beams that one wall has previously had installed.
There is essentially no gap between the beam and the concrete so I’m thinking the only solution is to go around the beams with the XPS board I have or to put the board on the concrete wall and use some kind of spray foam on the beams with the spray foam meeting the boards.
I’m also curious if anyone has recommendations on if I should add batts of insulation in addition to the 2″ XPS.
Any suggestions? I attached images to illustrate this.
Appreciate you guys
