Vermiculite is common mineral used in the past and somewhat still today as an insulating material for household attics and businesses. While newer vermiculite insulation is generally safe, a large amount older vermiculite insulation still in existence is not.
Separating dangerous vermiculite insulation from the harmless variety is the trace presence of asbestos. Asbestos, a commonly known carcinogen, found it’s way into mined vermiculite during the 70’s and 80’s by mistake and is the primary reason why the booming vermiculite remediation industry exists today.
To get specific, vermiculite mined by one manufacturer, Zonolite, is the primary culprit for asbestos vermiculite contamination. Many lawsuits have disseminated since the news of what Zonolite has done and serves as a basis for understanding the dangers of asbestos contaminated vermiculite.
