We are building a new house and are getting ready to install the drywall on the ceilings. We have installed a 6 mil plastic barrier on the underside of the rafters to act as an air & moisture barrier. The barrier will be sandwiched between the drywall and the rafters and under the blow-in insulation. I talked with another insulation guy that said he thinks it might trap moisture in the house and cause problems with the ceilings. He thinks we should tear out the plastic before we install the drywall ceilings.
Does anyone know if the plastic barrier will help or hurt us?
