Asbestos in Vermiculite and Zonolite Insulation

Asbestos contamination in vermiculite and vermiculite products has become a concern to many citizens throughout the country. Vermiculite contaminated with asbestos was used in the past as a poured-in insulation in attics. On its web site, EPA has updated information about Vermiculite and its uses, factsheets, Question and Answer documents, reports and links to EPA Regional vermiculite pages.
