ArmorWool boards offer a wide variety of benefits, including high-temperature resistance and low shrinkage, resistance to erosion from high velocity gasses, excellent thermal insulation performance and thermal stability, and more.

They can be used in applications such as thermal insulation for furnace linings, lining combustion chambers for gas-fired boilers and heaters, as well as high-temperature back-up insulation, chemical-resistant liners in furnaces operating in reduced atmospheres and many additional applications.

ArmorWool boards have classification temperatures ranging from 2200°F to 2900°F, with continuous-use temperatures from 1950°F to 2700°F.


Standard Grade Boards

ArmorWool X

ArmorWool X Board is a general purpose refractory board based on our 2300°F-rated RCF ArmorWool X fiber with selected inorganic and organic fillers to deliver high strength and performance in industrial applications.

Data Sheet

ArmorWool HP

Using a unique chemical composition (standard ArmorWool HP fiber) has led to the development of the ArmorWool HP board which has a classification temperature of 2550°F without the use of zirconia.

Data Sheet

ArmorWool ZR

ArmorWool ZR Board, with a classification temperature of 2600°F, is a proven solution in applications operating up to temperatures of 2400°F.

Special Grade Boards

ArmorWool HT

ArmorWool HT Board is a blend of low shot, high temperature RCF and high performance alumina fibers (PCW). It has excellent dimensional stability, minimum shrinkage, and a classification temperature of 2700°F.

Data Sheet

ArmorWool 2900

ArmorWool 2900 is manufactured from a blend of low shot, Armorwool HA fiber and high performance alumina fibers (PCW). The result is a board which can be used in a continous temperature of 2700°F at virtually no shrinkage. The use of inorganic binders minimizes loss of strength and fumes at first firing.
