Zonolite Vermiculite Attic Insulation Trust
Settlement Deadline: February 23, 2023

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 insulation. Zonolite is the trademarked name of a naturally-occurring mineral vermiculite product that is mined in Libby, Mt., 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.

If Zonolite attic insulation was installed in a structure that you currently own or rent, or that you previously owned or rented, and you incurred expenses associated with the removal, abatement, reinsulation or containing the insulation, you are eligible to submit a claim for reimbursement.

The Trust applies to both residential and commercial buildings.

Up to $4,125. The Trust may provide up to 55 percent of the abatement cost for eligible claimants, up to a maximum of $4,125. The Trust does not provide compensation for diminution of property value or economic loss.
