Not all vermiculite contains asbestos. It is important to get vermiculite testing prior to removing or disturbing it. An indoor environmental professional will know where and how to take proper samples, which will allow the lab to determine whether the vermiculite is asbestos-containing.
Asbestos-containing vermiculite insulation carries a higher risk potential for exposure due to its friability, in comparison to non-friable asbestos materials (such as vinyl floor tile, for example).
