Chuck; The keys are the direction the vapor travels and whether there is a condensing surface that is colder than the dew point in the path of travel. The second law of thermo-dynamics basically states that things move from more to less, from hot to cold, and from wet to dry ( learned this from...

Greetings Il Gattopard: For what it is worth: You are correct that the vapor retarder is to be placed between the warmer humid air (higher vapor pressure) and the cooler environment (lower vapor pressure); that does mean that the vapor retarder is to be on the warm side of the insulation. If...
