Vermiculite is a common attic insulation described as small, silver/black/white lightweight squares found in Zonalite and other insulation that contains small amounts of dangerous asbestos fibers.

The Environmental Protection Agency (EPA) is WARNING homeowners who may have Zonolite Attic Insulation in their homes to only disturb the insulation if they have hired professionals to perform the job. Zonolite Insulation was a do-it-yourself insulation material manufactured and sold between 1963 and 1984. It is brownish-silver and comes in accordion shaped chips. The EPA believes Zonolite may likely contain unsafe levels of asbestos. Approximately 940,000 U.S. homes contain this type of insulation. Asbestos should only be removed by trained professionals! If you think your home may contain this type of insulation, contact Healthy Homes for help!

DO NOT DISTURB IT! Any disturbance has the potential to release asbestos fibers in the air. Asbestos is a mineral fiber that has been used in a variety of household and building materials. It has been shown to cause lung and stomach cancer in people exposed to its microscopic fibers. When asbestos containing materials, such as vermiculite insulation are disturbed (i.e. remodeling, demolishing, or building a home), the fibers are easily inhaled and ingested. Once inhaled, the tiny fibers stay lodged inside your body tissue, increasing your chance of developing serious illnesses. If you plan on remodeling or have had roof damage, and have seen this Vermiculite Insulation in your attic or walls, hire a trained and certified professional to evaluate the environmental impact.
