Vermiculate attic insulation looks like pebble-like usually light-brown/pink or gold in color. Expert reports claims that vermiculite attic insulation sold under the trade name “Zonolite” from 1940 to 1984 may be contaminated with asbestos. It is known that most of the world’s supply of vermiculate came from the mine near Libby, Montana. This mine has natural occurring asbestos mineral which resulted in the contamination of the raw vermiculate, according to media reports.
