Q: Does Vermiculite Contain Asbestos?
A: No. The Vermiculite that we use in our product and the Micalite Boards is checked by an independent laboratory for the presence of Asbestos. Asbestos has never been detected in our product. Vermiculite is sometimes associated with Asbestos because of an incident that took place in Montana, USA. This particular mine has been closed now for many years and Dupré has never used vermiculite from this source. The asbestos found in the material from Montana was not due to the vermiculite but to the presence of another mineral.
