vapor barriers in bathrooms

In reply to Where does a vapor barrier fit in? by Fred in TX on September 6th, 2000 03:40 PM [Go to top of thread]

We have developed mold or fungus in the drywall of our master bathroom in Vermont. To add to the confusion, there is significantly less insulation over the bathrooms. Upon removing the drywall, there was no evidence of fungus/mold on the attic side and the vapor barrier (plastic) was intact. Our attice has a layer of fiberglass batts which are then covered with blown-in 'stuff'. In order to fix this problem, should I remove the vapor barrier, thereby allowing the moisture to 'breathe' through the walls and into the attic OR simply replace the ceiling with blueboard and insulate over the bathroom better? I might add that the shower is ventilated and has no mildew on it at all. Thanks
