ZAI Trust: get up to 55%
of your removal costs back.

What is Zonolite?

Zonolite is a brand of vermiculite attic insulation manufactured by W.R. Grace & Co. and sold widely from the 1940s through the 1980s. It looks like small, gray-brown pebbles or pellets and was poured loose into attic spaces.

The vermiculite used in Zonolite was mined primarily from the Libby, Montana mine — which was contaminated with naturally occurring asbestos. As a result, most Zonolite-brand vermiculite contains asbestos fibers.

Do you qualify?

Yes. The Zonolite Attic Insulation Trust became active in 2014 as part of W.R. Grace's bankruptcy settlement. The Trust is currently accepting claims. There is no announced end date for the program.

The Trust reimburses up to 55% of removal costs, capped at approximately $4,935. For a typical vermiculite removal project costing $6,000–$9,000, this means $3,300–$4,935 back in your pocket.

The Trust applies to vermiculite that is Zonolite brand or cannot be confirmed as a different brand. Since Zonolite was the dominant vermiculite insulation product in the US market, most vermiculite attic insulation qualifies. We document the brand identification as part of our inspection process.
