Calcium silicate pipe insulation is a rigid, fire-resistant thermal insulation material specifically designed to wrap pipes, ducts, and other cylindrical surfaces. It’s engineered from a blend of calcium silicate (a compound formed from calcium oxide and silica), reinforcing fibers (often cellulose, mineral wool, or synthetic fibers), and binders. This combination creates a dense, durable material that excels in high-temperature environments while maintaining structural integrity.
