Exported to Europe, the United States, and many other regions, our boards are trusted for their quality, consistency, and proven reliability in demanding industrial environments.

What is Ceramic Fiber Board?

Ceramic fiber board, sometimes referred to as refractory ceramic slab, fireproof ceramic board, or high-temperature resistant ceramic panel, is a lightweight, rigid insulation product manufactured from high-purity ceramic fibers. It is designed for applications where both thermal stability and mechanical strength are required. With low thermal conductivity and high resistance to heat, ceramic fiber board is widely used to reduce energy loss and protect equipment operating at extreme temperatures.
