Over the years, a wide variety of materials have been used to insulate homes and other buildings. Sawdust, corn cobs and straw are some naturally-occurring materials that have been used as insulation in the past. Vermiculite insulation also belongs in this category.
Vermiculite is a mineral that is light and shiny, like mica, with a similar flaky texture. When heated to high temperatures, vermiculite expands and gains the qualities that make it an effective insulator -- a lightweight, porous, fire-resistant material. Pieces of vermiculite insulation can be up to an inch long, but most are smaller pieces and particles.
Although vermiculite insulation is still available today, it's used more for specialized applications rather than for home insulation. Older houses may still contain vermiculite insulation, which resembles kitty litter in appearance.
