I am hoping you can advise me regarding my wine cellar problem. I built my 6'x8' wine cellar last summer. I use a through-the-wall Wine Guardian cooling unit.
I installed a 6-mil plastic vapor barrier on all warm-side walls(2x6 construction with green board)and over the ceiling joists and sealed all seams. I installed R-30 fiberglass insulation between he ceiling joists and R-19 in walls. I covered the ceiling with non-porous plastic paneling.
I am getting pools of water on top of my plastic ceiling panels - in between the ceiling vapor barrier/insulation and the panels. I didn't want to put green board in the ceiling for this very reason, so I didn't. I just have the plastic paneling as my ceiling. I am assuming that I created a sealed environment where the moisture from humidity condenses in the ceiling and cannot escape from between the vapor barrier and the plastic paneling.
Is the plastic paneling the problem?
If so what would be a better solution for covering the ceiling to hide the insulation if I had to remove the plastic panels?
I don't want the excess moisture to lead to mold problems.
What would you recommend I do?
