Dugger: I was originally thinking of having one area for both making and storing. After thinking more about it, I plan on having seperate storage and making areas. I don't want to be working in a 55 deg. F. space, or have to worry about temp fluctuations because we're in there working. Therefore, the storage area will be temp and humidty controlled. My basement, as is, has no moisture problems. As far as creating moisure goes, it will be from whatever moisture is released from the winemaking process (right now from kits and fresh juice) So, my question regarding a vapor barrier in the ceiling stands-what's the best way to do that? To me, it still seems like if, in the ceiling or the walls, you have a vapor barrier against the warm space, then insulation then your green board or sheet rock, your gonna trap the 70% moisture in your storage room between the vapor barrier and the insulation. Won't that eventually destroy the insulation properties of fiberglass batting?
