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...
Be careful not to confuse a 10% solution of Kmeta for a 10% solution of SO2. Kmeta is about 57% (plus or minus) SO2 with the other 43% being Potassium. So to make a 10% solution of SO2 add 175 grams SO2 and add water for a total of 100 ml.
BTW this is my first post on the site although I have...
