Bison Panel, also known as cement bonded particle board, is a versatile building material primarily composed of cement, wood, and water with some added chemicals. It’s known for its fire resistance, weather resistance, and termite/vermin resistance due to the mineralization of wood particles during manufacturing. Bison panels are available in various thicknesses and are used for both interior and exterior applications.
