Ceramic Insulation is the best solution for your high temperature insulation. The mixture of refractory fibers and binders, which have low organic content is vacuum processed into high temperature ceramic fiber board that imparts good mechanical strength even after heating. Ceramic Board is a refractory board which has low thermal conductivity and high tensile strength and excellent resistance against thermal shock and chemical attack.
