What are the main differences between ceramic fiber insulation and mineral wool insulation?

Ceramic fiber insulation and mineral wool insulation are both high-temperature insulation materials but have distinct characteristics. Ceramic fiber insulation is made from ceramic materials and has a higher temperature resistance, often used in extreme heat environments. It is lightweight, flexible, and has low thermal conductivity, but can be hazardous due to potential health risks from dust inhalation. Mineral wool insulation, primarily composed of rock or slag, is less resistant to high temperatures but offers good acoustic properties and is more environmentally friendly. It is denser and heavier than ceramic fiber, providing better sound insulation but with higher thermal conductivity.
