It's been very humid here for the last week and my problem is we now have moisture dripping down the inside of the vapor barrier. I'm getting all kinds of different and conflicting advise including the option of applying tar paper on the block wall before framing and insulating the wall. I also know that the residential building code in my area requires venting that runs from the wall cavity up to the attic but in this case trying to cut and run vents up through the flat roof of this old building into the roof cavity would be a massive undertaking. The way I look at it if the building still had a flat roof and venting was not possible there must be an accepable and code legal way of eliminating all the moisture build up.
Any help will be appreciated
Thanks in advance
