Can blown insulation cause mold? in general, blown-in cellulose insulation, surprisingly, is not found moldy.” Both fiberglass and rockwool insulation (inorganic materials) have been tested. In the rockwool insulation tests showed enough nutrients to keep mold spores alive, probably from dust in the mineral fibers.
How do I know if my insulation has mold? Place a magnifying glass close to the insulation to observe dirt particles or mold spores that might be forming on your insulation sheets. Take note of any brown, black, green, pink, orange or yellow particles. Insulation sheets are a solid color such as white, which will make the dirt and mold easy to spot.
