What is Vermiculite?
Concerns about vermiculite insulation
A mine near Libby, Montana, was the source of over 70 percent of all vermiculite sold in the United States from 1919 to 1990. There was also a deposit of asbestos at that mine, so the vermiculite from Libby was contaminated with asbestos. 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, you should assume this material may be contaminated with asbestos and be aware of steps you can take to protect yourself and your family from exposure to asbestos.
If you have vermiculite insulation
- Full Containment
- Negative Air with HEPA Filters
- HEPA Vacuums
- Full 3 Chamber Decon.
- Personnel Protective Equipment on all employees when handling the materials as to prevent cross contamination to other areas.
- Final Visual and Air Clearance after the completion of each vermiculite project, to ensure all areas are safe and pass stringent EPA, State, and Federal Regulations.
