Ultratemp-I (600ºF Fiber Reinforced Cement Board)

Ultra Temp I is a noncombustible, asbestos-tree, high density board. It is engineered to handle higher temperatures, loads, and electrical conditions with less shrinkage ancell nameegradation compared to previous non-asbestos formulas.

Ultra Temp I can accommodate 600ºF after initial heat conditioning. Ultra Temp I may be used in a wide variety of applications where a combination of high strength thermal stability, electrical insulation or machinability is required.
