Zonolite vermiculite attic insulation trust

W.R. Grace has funded the Zonolite Attic Insulation Trust to reimburse claimants for legitimate property damage claims associated with the removal, abatement, and/or containing the asbestos-contaminated vermiculite insulation.

Zonolite is the trademarked name of a naturally-occurring mineral vermiculite product mined in Libby, Montana, and was sold as attic insulation from the 1940s through the 1980s.

Popular within the construction industry because it was lightweight and fire-resistant, Zonolite insulation was installed in millions of homes throughout the United States. However, the vermiculite mined in Libby is known to contain a small amount of asbestos, which can be harmful if it is disturbed and particles are released into the air.

Grace, which operated the Zonolite company from 1963 to 1990, reached a settlement over the Zonolite asbestos insulation claims and funded an independent Zonolite trust and claims facility to allow claimants to seek partial reimbursement for the expenses associated with removal or containment of the Zonolite asbestos insulation.

Vermiculite is a natural, flaky mineral, according to the U.S Environmental Protection Agency (EPA). When heated to a high temperature, the flakes expand, making vermiculite a light-weight, fire-resistant, odorless material.

Zonolite-branded vermiculite accounts for about 75 percent of the used in homes, according to the trust website. Consumers who have vermiculite are advised not to assume it is the Zonolite brand.

In addition to funding an independent trust that will operate for at least 20 years, Grace will also educate the public about potential health effects that are associated with asbestos-containing vermiculite.

The Zonolite insulation trust is only for abatement claims. Those who suffered injury from personal exposure to Zononlite asbestos insulation or any other Grace asbestos products can obtain information about a separate fund by contacting Mark T.
