Case Name

Zonolite Attic Insulation Trust

Case Summary

Zonolite Insulation is the trademarked name of a product mined in Libby, MT and sold as attic insulation between the 1940’s and mid-1980’s. 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. Unfortunately, “Libby vermiculite” or Zonolite, is known to have contained a small amount of hazardous asbestos. Although not all vermiculite is the Zonolite brand or contains asbestos, the EPA advises that you should assume that vermiculite contains asbestos. Zonolite attic insulation, or “ZAI,” may prove harmful to residents because it remains in many attics and homes across the United States and because it is considered “friable”, i.e, easily disturbed and distributed into the air. Pursuant to a legal settlement, W.R. Grace, which operated the Zonolite company from 1963-1990, has funded an independent Trust and claims facility from which eligible claimants may receive partial reimbursement of their cost to remove or contain ZAI in their homes. The Trust will operate for a minimum of 20 years educating the public about the existence of the Trust and the potential health effects associated with asbestos-containing Vermiculite/ZAI. Removing Zonolite as a do-it-yourself project should not be attempted because of the friable asbestos.

    I had this in my house that I lived in during the early 90’s in Metropolis,Illinois. I spent a week putting this into my home do to it being such a easy to handle insulation without having to fight with a big bulky thick insulation in my home at 407 West 7th Street, in Metropolis,Illinois.

  9. S L Frederiecks says:

    I just got my report from the lawyer: it’s findings are ambiguous, at best, and causes me to be suspect of the scheme. It said my sample was not tested for the prescence or non presence of asbestos but is consistent with vermiculite mined in Montana. This gross generalization makes the finding indeterminent. Lawyer speak? I can’t be sure.
