   • Asbestos duct wrap is made of asbestos fibers, known for their durability and heat resistance, woven into a fabric-like structure.
   • Modern duct insulation typically consists of fiberglass, foam, or reflective foil, designed to be safer and more efficient.
2. Appearance and Texture:
   • Asbestos duct wrap is usually white or off-white, characterized by a rough, fibrous texture, often appearing fluffy or layered with a powdery surface.
   • In contrast, modern duct insulation tends to have a more uniform appearance. Fiberglass insulation is commonly yellow or pink with a consistent texture, while foam insulation is smooth and available in various colors, and reflective foil insulation features a shiny, metallic finish.
3. Health and Safety:
   • Inhaling asbestos fibers poses significant health risks, potentially leading to severe conditions such as asbestosis, lung cancer, and mesothelioma. Thus, identifying and handling asbestos duct wrap safely is imperative.
   • Modern insulation materials are engineered to minimize health risks. While fiberglass may cause skin irritation, it lacks the severe health concerns associated with asbestos. Foam and reflective foil insulations are generally safe when installed correctly.
4. Installation and Maintenance:
   • Due to its age and friability, asbestos duct wrap often requires professional removal and disposal, adhering to strict safety regulations to prevent fiber release.
   • Modern duct insulation is typically easier to install and maintain, allowing for standard tools to be used without requiring specialized removal procedures.

Recognizing the differences between asbestos duct wrap and modern duct insulation is crucial for ensuring safety and compliance. Here are some actionable tips:
