Watched a Building Science video by Belinda Carr where she demonstrated that Mineral wool is water-resistant and fiberglass easily absorbs water.
I took a couple of small pieces of insulation and applied water droplets to it and the insulation soaked up the water like a cotton ball.
My question is, does mineral wool have the same water-resistant quality in loose-fill form as its dense-form? Does its water-resistant quality fade over time?
