I have an interior wall with an attic space on the outward side. The wall is 2x6 with fiberglass insulation with a paper vaper barrier. Our builder installed Thermo-Ply on the attic side which covers the raw fiberglass. I am finding a great deal of moisture between the inside of the Thermo-Ply and the fiberglass. How can this happen? The attic is well ventilated. Thanks, Dave
