What is Vermiculite Made of and Is It In My Home?

Updated: Jan 6

According to multiple State Department of Healths’ including IDPH, houses that used vermiculite were built in the 50’s, 60’s, and potentially the 70’s. “Vermiculite has been used in building insulation, potting soil and fertilizer. Unfortunately, the vermiculite contains naturally-occurring asbestos called tremolite-actinolite.”

What Does It Look Like

Vermiculite resembles gold kitty litter. They are brownish-gold and are about ½ inch in size. Pieces look like they are made of several layers.

How Does Vermiculite Affect My Health?

“Most people exposed to small amounts of asbestos will not experience adverse health effects. A person must generally be exposed to asbestos for a long period of time (10 or more years) before health effects occur.

Illnesses caused by long-term asbestos exposure include –

  • asbestosis, a lung disease caused by breathing in asbestos fibers causing irritation and scarring of lung tissues

  • mesothelioma, a form of cancer in the lining of the lungs, chest, abdomen and heart caused by exposure to asbestos

  • lung cancer, tumors of the lung that are linked to asbestos exposure as well as other sources of exposure such as cigarette smoking.”
