vapor barrier for wine cellar question

13 years ago

Hi, I'm building a passive wine cellar in my basement in Ontario, Canada. I've read how the vapor barrier needs to go on the warm side, but in my case it's not that simple.

I don't heat or cool my basement, so the main space is warm in summer and cold in winter. The wine cellar, if I build it right, will moderate the worst of this, so that in winter it will be a little warmer than the rest of the basement (no drafts, etc., plus constant temperature from the tile on concrete floor) and in summer it should be cooler. In other words, where the warm side is depends on the season.

So . . . what do I do for the vapor barrier?
