What Does Asbestos Insulation Look Like in the Attic?

Asbestos was a popular building material for many years due to its fire-resistant and insulating properties. However, it's now recognized as a dangerous health hazard, with prolonged exposure leading to serious respiratory illnesses like mesothelioma and lung cancer. If you have an older home, there's a good chance that it may contain asbestos insulation, especially in the attic.
