papab,
I stand corrected on the fiberglass being hydrophobic, thanks- I won't spread that myth anymore. (EDIT I just reread my post and I didn't say fiberglass was not hydrophobic just that it fills with water and mats down- which it does. If pushed I would have not known it is hydrophobic... ah well.) My mistaken belief is from pulling wet matted insulation from the bottom of walls of a building and literally being able to wring moisture from them. The building was a high humidity structure with no internal vapor barrier and painted sheathing on the outside. The sheathing was mold filled, as was the fiberglass and the sill was rotted as was the sheathing and the internal sheet rock was soft, degraded and had surface stains. In the vehicle I removed it from it was slumped into the bottom of the sidewall, wet and rusty as was the drain channel due to its having matted and closed off the drains. These situations have no way for the fiberglass to dry in any reasonable time. You are doing due diligence, good for you.
