01 Dec 10 - 10:32 PM (#3044600) Subject: BS: Asbestos-vermiculite- Zonolite Insulation From: Janie This is not a new story, but it is news to me, and I thought it might be to others. Montana mined vermiculite with asbestos (Note: as with so many AOL articles, this one is written in lurid tabloid style, but further research backs up the facts pretty darn well.) I'm gonna be checking on the insulation in my attic, and try not to worry about all the potting soil mixes I have played around in for the past 20 years, both purchased and that I mixed myself from purchased ingredients, including vermiculite. I have no way of knowing, now, where the vermiculite I purchased came from. |

02 Dec 10 - 06:12 AM (#3044753) Subject: RE: BS: Asbestos tainted Zonolite Insulation From: Janie I can't seem to make a link that works to that first article, Ebbie. It is still one of the featured articles in the scrolling news box on AOL.com, but don't know how long it will be up. Here is information from the EPA http://www.epa.gov/asbestos/pubs/verm.html. The mines at LIbby provided 70% of the vermiculite sold in the USA between 1919 and 1990. and was in production for approximately 75 years. The Grace Company, owner of the Libby mine, stopped producing the Zonolite insulation in the early 1980's, "for economic reasons." Until then, it was widely used as attic insulation, and is thought to be in something like 35 million homes. |

Sure, it probably was "for economic reasons"--like the cost of litigation and almost-surely the burden of paying damages. The early 80s was, as I recall, just about the time that there began to be heavy and growing publicity about the dangers of asbestos. Dave Oesterreich |

02 Dec 10 - 08:39 AM (#3044852) Subject: RE: BS: Asbestos tainted Zonolite Insulation From: Charley Noble Vermiculite insulation can certainly be nasty stuff. I'd certainly have a professional inspect any such installation before trying to remove it. I also worry about the long term consequences of spraying fiberglass insulation into attics, and inhaling their fibers. I'm less worried about fiberglass installed in batts. Charley Noble |

Packages containing info and a form to join a class action lawsuit were sent to homes (all close to 50 years old) in my neighbourhood. These packages were delivered by mail. The deadline for claims was at 6PM on the day of delivery. That was last fall. Imagine that. |

Nobody ever even mentions asbestos in the UK any more. |
