Ceramic Boards

Temp Grade: 2300°F

Duraboard LD Insulation

Duraboard LD insulation has the same density and temperature rating as Duraboard RG insulation, and is manufactured to tighter dimensional tolerances with an excellent finished surface.

Duraboard RG Insulation

Duraboard RG (Refractory Grade) insulation is a cost-effective insulating board manufactured with the specific requirements to provide a high modulus of rupture and compressive strength, as well as, high abrasion and hot gas erosion resistance.

Duraboard HD Insulation

Duraboard HD insulation is a high-density board product with the same high level of dimensional and surface uniformity as Duraboard LD insulation, enhanced compressive strength and a higher modulus of rupture.

Duraboard 350ES

Duraboard 350ES is manufactured with more than three times the strength of standard boards of similar densities and thicknesses.

Duraboard 500 ES

These products use a unique fiber formulation to obtain high strength and machinability not normally achieved in lightweight, ceramic fiber board products allowing for easier handling and fabrication.

Temp Grade: 3000-3272°F

Duraboard 3000 Insulation

Duraboard 3000 insulation, the highest temperature-rated board manufactured by Unifrax Corporation, provides maximum high-temperature stability and shrinkage resistance.

Fibermax Duraboard 1700 and 1800

Duraboard 1700 and Duraboard 1800 exhibit excellent thermal stability at very high operating temperatures.
