Zonolite FAQ

Zonolite

Q: What is Zonolite?

A: Zonolite is a brand name of vermiculite attic insulation containing harmful minerals (asbestos and others) that was mined from the Libby Mine in Libby, Montana beginning in 1919. It was used in many construction materials including insulation.

Q: What is the Libby Mine?

A: Beginning in the 1920’s, The Libby Mine was the worlds largest supplier of vermiculite insulation. Products originating from this mine were used all over the United States, including in insulation and other construction materials. Citizens of Libby, Montana, often suffered from asbestos-related diseases such as mesothelioma from the high levels of toxic asbestos dust in the area.

Q: When did the Libby Mine discover that the product was dangerous?

A: W.R. Grace & Company took over the operation of the mine in 1963. Even though they knew the product contained asbestos and was harmful, they continued to mine it and failed to warn workers or citizens of Libby. Currently, more than 2000 residents of libby are suffering from asbestos-related illnesses.

Q: Is Zonolite dangerous?

A: Zonolite was made from minerals that were mined out of the Libby Mine. Because the Libby Mine contained large amounts of asbestos, Zonolite usually will test positive for asbestos as well. Zonolite should be considered dangerous to your health. Zonolite and vermiculite insulation often contain asbestos, which can cause a number of health problems including lung cancer. Never attempt to remove asbestos insulation yourself; always call a professional.
