Ceramic fiber board is a rigid insulation panel made from alumina-silica fibers combined with inorganic binders and additives. Unlike flexible blankets or papers, these boards are dimensionally stable, load-bearing, and suitable for high-temperature furnace linings. They are widely used where high thermal efficiency, structural integrity, and long-term service are required.
