Ceramic fiber insulation is known as a “refractory material” due to its high heat-resistance and stability at high temperatures. Ceramic fiber is largely made of aluminum silicate, which includes fiber made from various polycrystalline fibers and molten glass. This refractory material is lightweight, has low thermal conductivity and heat storage, and protects against corrosion. Ceramic fiber insulation comes in various forms including blanket, board, cement, paper, tape, and more. Temperature ratings will vary by product.
