Abating Zonolite Insulation



1290630547014Years Produced: 1940 – 1980

Zonolite Insulation is the trademarked name of a product sold as attic insulation between the 1940s and 1990s. Consisting of the naturally occurring mineral vermiculite, Zonolite

was used for decades to insulate millions of American homes. This attic insulation was typically gray-brown or silver-gold in color, consisting of a pebble-like texture. Part of its popularity within the construction industry stemmed from the fact it was lightweight and fire-resistant. Although all vermiculite does not consist of asbestos, Zonolite insulation was tainted with asbestos. Zonolite may prove harmful to residents because it remains in many attics and homes across the United States and the world. Removing Zonolite as a do-it-yourself project should not be attempted because the material contains high amounts of asbestos.

Fast Fact: Between 1919 and 1990, 70 percent of the world’s supply of vermiculite came from the asbestos-contaminated Libby mine, according to the U.S. Environmental Protection Agency.
