Hi all, My workshop building is built into a hill on two sides. I have applied foam board to my block walls in my shop and then studded out the walls so I can apply fiberglass batts in the cavities. I went out today and noticed condensation on the foam. The foam has been installed for about a month now and I have not noticed this up to this point. It has been extremely wet out with all the rain we have had lately so I am wondering if this is the reason for the condensation? Also the outside temp has been the same for a while now. There were some cardboard boxes in my shop that also seemed damp? I am hoping once I get the fiberglass insulation in there the air will not get to the foam as much so it will not condensate. Any thoughts on this? Thanks in advanced.
