Vermiculite is a mineral that once was commonly used in home attics as thermal insulation. Because it was such a popular building material from the 1920s until the late 1980s, it is still found in the ceiling joist cavities of many homes today.
Roughly 80 percent of the vermiculite used in US homes before 1990 was produced by a mine outside of Libby, MT. In 1990, when it was discovered that this mine was heavily contaminated with asbestos, builders began to look elsewhere for vermiculite supply.
There are different types of insulation that can be used for homes — vermiculite happens to be loose filled insulation that is mixed with small grade gravel nuggets. It has a texture that is soft and squeezable, similar to popcorn. It typically has different colors mixed together, like silver, dark brown, gold, light brown and gray.
