What Are Asbestos and Cellulose Insulation?

Asbestos Insulation - Definition Asbestos is a naturally occurring mineral fiber used extensively as an insulating material until the late 20th century.

• Properties It is known for its durability, fire resistance, and insulating properties.

• Health Risks Asbestos fibers, when disturbed, can become airborne and inhaled, leading to severe health issues like asbestosis, lung cancer, and mesothelioma.

Cellulose Insulation - Definition Made from recycled paper products, cellulose insulation is considered an eco-friendly alternative.

• Properties It is treated with fire-retardant chemicals to improve safety.

• Safety Unlike asbestos, cellulose does not pose a cancer risk, making it a preferred choice for modern homes.
