Fiberfrax Duraboard products are manufactured from Fiberfrax refractory ceramic fibres, blended with specially selected inorganic and organic binders to give rigid boards with exceptional characteristics.
Fiberfrax Duraboard 1500 & 1600 are produced from a blend of Fiberfrax and high alumina polycrystalline fibres. This combination increases the continuous operating temperature capability, provides very low shrinkage at elevated temperatures, whilst maintaining excellent insulating properties. Fiberfrax Duraboard products are available in a wide range of sizes and thicknesses.
