Millions of homes across North America have vermiculite insulation which may contain asbestos. A mine near Libby, Montana, was the source of over 70 percent of all vermiculite sold in the United States from 1919 to 1990. Unfortunately, the vermiculite from Libby was contaminated with asbestos that was associated with the deposit. 





Vermiculite from Libby was used in the majority of vermiculite insulation in the United States and was often sold under the brand name Zonolite.  

If you have vermiculite insulation in your home the EPA recommends that you treat it as if it were asbestos containing. For peace of mind or confirmation of the presence of asbestos, EMSL provides quick and affordable asbestos testing solutions. 

The only way to know for sure if vermiculite insulation in a home or building contains asbestos is to have it tested. If asbestos is found, then the proper procedures can be implemented to keep people safe from exposure.

If you would like a qualified professional to come and test your property, contact EMSL at 1-800-220-3675.
