Ceramic fibre board (also called ceramic fiber board) is a rigid, high-performance insulation material engineered from alumina-silica ceramic fibers (typically 70–90% alumina [Al₂O₃] and 10–30% silica [SiO₂]). Unlike soft, flexible ceramic fiber blankets, boards are pressed or extruded into dense, flat sheets, making them ideal for structural applications where shape retention and mechanical strength are critical.
