Can wet uninstalled R-30 fiberglass rolls be dried & used?

Is there any way to dry and uncompress rolls of R-30 unfaced fiberglass that got wet?

I had some rolls covered on a tarp outdoors when heavy rains hit. Water collected on the tarp and soaked into the bottom of 5 rolls through some rips in the plastic.

I've removed the plastic from the wet rolls to let any soaked water drain. Unrolling one of them, I found that about 75% of the width is dry and expands to its normal thickness. Is there any way to dry out the portions that took on water, or are all these rolls a total loss?

You could dry it out. If any dirt (organic) got into the f.g. and it warms up and is still wet after install, it could mold; http://www.inspectapedia.com/sickhou...rglassMold.htm
