Ceramic fiber insulation boards used in buildings come in several types, each with unique properties. These include: 1) Standard Ceramic Fiber Boards, which offer basic thermal insulation; 2) High-Temperature Ceramic Fiber Boards, designed for applications requiring resistance to higher temperatures; 3) Low Biopersistent Ceramic Fiber Boards, which reduce health risks by minimizing the release of fibers; 4) Alkaline Earth Silicate Boards, known for their excellent fire resistance and low thermal conductivity; and 5) Micro-Porous Silica Boards, which provide superior thermal insulation and are often used in high-temperature environments. Each type is selected based on specific application needs, such as temperature resistance, fire safety, and health considerations.
