There's just SO MUCH to read sometime I get lazy and ask.
So they vaccummed up some mold in old dirty fiberglass. It's the organic dirt that's supporting the mold growth, not the inorganic fibers. But that's just a technical quibble. In the real world, dirty fiberglass could certainly be an ugly mold habitat.
"In the real world, dirty fiberglass could certainly be an ugly mold habitat." ------ I have never found fiberglass insulation without dirt from moving air -- anywhere...... but that is only in attics, walls, and under-floor. And after 10 years (or less) the batts compress from 6" to 3", underfloor and attics, but walls take longer for gravity to effect because of the flanges. I did not install it, nor would I recommend fiberglass to anyone after my research. (I hate being duped....)
