So it is required by the code in my town that I have to have a vapor barrier between the sheetrock and insulation. BUT, everyone I talk to tells me that vapor barriers are bad and they don't let the house breath, if I install it I will have nothing but problems. SO my question is, who is right? What steps do I need to take to make sure I don't get problems since it is required by code or is it an old wives tale? Thanks!
