Do other insulations manage moisture?

No insulation manages moisture as well as wool.

NO! Cotton absorbs water and is treated with chemicals to be temporarily hydrophobic. Fiberglass acts like a sponge and then turns into a moldy science project gone bad. Cellulose is paper, attracts moisture and this too will become a moldy disaster waiting to happen. Rock Wool is laden with chemical binders and uses an absurd amount of energy to create the product while emitting particulate and harmful chemicals into our fresh air as part of the process. And it does nothing to manage moisture. Thinsulate do not absorb water, but then where does the water go? It collects in the bottom of the cavity. Foam will not absorb water either but instead forces the water into the cavity to collect and corrode. Wool absorbs and releases moisture – absorbing too much when it is present and releasing it back into your space when dry.
