What it is: Loose pebble-like attic insulation that may contain asbestos (Zonolite).
Why it matters
Much vermiculite came from an asbestos-contaminated source and is hazardous if disturbed.
Why it's common in Bloomington
Possible in older Bloomington attics that were never re-insulated.
Signs to watch for
- gray-brown accordion-like pebbles in the attic
What we check during the inspection
