Ceramic Fiber Insulation is a lightweight insulating product. It has low thermal mass which means that it does not retain heat, has low thermal conductivity, and is an extremely effective insulation material. Its high thermal shock resistance makes it suitable for applications where traditional refractories cannot be used. The insulation is manufactured from high-temperature synthetic wool capable of withstanding consistent temperatures exceeding 1200 degree Celcius (2192 Fahrenheit ). The use of ceramic fiber is localized and found in different areas of a boiler. Ceramic Fiber Insulation is very useful.
