Vermiculite is a hydrous, silicate mineral that is classified as a phyllosilicate. There you go…

Seriously though, this natural mineral is commonly used in hundreds of everyday commercial products. It is important to note that the real danger is Asbestos. Although not all Vermiculite contains Asbestos, many products made with Vermiculite contained Asbestos until the early 1990’s. Since, Vermiculite is vigorously tested to ensure that no Asbestos is present.

In the home our primary concerns are that Vermiculite was used to manufacture high-temperature or refractory insulation, as well as roof and floor screeds and insulating concretes. If your home has it or the home your looking at does, then there’s a problem.

The Libby mine in Montana produced approximately 80% of the world’s Vermiculite until the early 1990’s, when it was shut down for Asbestos contamination. That means that if Vermiculite is found in the home, there is a very good chance that there is Asbestos contamination.

Unfortunately, Asbestos has been directly linked to Cancer and the only way to ensure protection is to ensure that your home is Vermiculite free. That’s one of the benefits of having a trained and certified Home Inspector on the hunt!
