Does wet insulation need to be removed? The short answer is yes (most of the time.) If you're wondering why, here is some information that may help to educate you about the process:
Cellulose insulation is paper based, but it is also treated with chemicals (borates) that suppress mold growth. Fiberglass does not support mold growth, but it gets dirty, and the dirt grows mold, and it is often paper faced and this paper grows mold.
Fully saturated insulation should always be removed to prevent mold growth. Wet insulation can be dried depending on the category of water that affects it. If it is clean water, drying should be attempted before removing and replacing the insulation. Typically the insulation takes a long time to dry and doesn't fully return to its original dry standard.
