    Question condensation between OSB and insulation

    I have condensation between the OSB and the unfaced insulation in my walkout wall of my basement. I have spray foamed the top and bottom plates and taken off the house wrap, but every time I put the insulation back up, I have condensation on the inside of the OSB. If I leave the insulation out, no condensation.

    Where was the house wrap installed ?
