Milt, question for you:

In situations like this, people often use blown-in insulation. I have always wondered why they can do so without a vapor barrier. What are the long-term effects of having insulation w/o a vapor barrier?

At my wife's family cottage (built about 1910) , they used blown-in about 20 yrs ago. Now, years later we are having tons of trouble with moisture. Paint peeling & plaster is coming loose from the lathe.
