It was the trademark name of vermiculite product used for attic insulation in U.S. Zonolite insulation was installed in the number of buildings in the United States between the 1940s and 1980s. It was popular within the construction industry due to properties like fire-resistant and lightweight.

Further, the vermiculite product mined in Libby contains some amount of asbestos, which cause harm to health.

The Role of W.R Grace in Zonolite
