Unhealthy Attic Insulation

Health Risks With Vermiculite? Maybe.

A homeowner wrote  to me about finding “Vermiculite Insulation Risk” in the attic and wanted to know if vermiculite posed a health risk:

  • “Does vermiculite contain asbestos?”
  • “Should this be cause of concern?”
  • “What should be done?”
