W.R. Grace announces the Zonolite Attic Insulation Trust http://www.zonoliteatticinsulation.com W.R. Grace has started a trust fund to allow homeowners the opportunity to receive partial funding to have Zonolite vermiculite attic insulation removed from their home. Samples will be sent to the trust to be analyzed by labs employed by W.R. Grace. A proprietary method is used for analysis of the vermiculite by chemical means via ICP with barium as the signature cation. It identifies whether the vermiculite is from the Libby deposit, rather asbestos content. The FAQ section has all the basic facts.
