Gemcowool® Ceramic Fiber Insulation

FG21-108, FG21-109

MSDS | Technical Data Sheet

Versatile industrial insulating materials for 2100ºF applications

Gemcowool® products are formed using a composition of mineral wool fibers and include both inorganic and organic binders. Gemcowool® materials can be utilized in many of the same applications as refractory ceramic fiber materials, provided temperature does not exceed 1150°C (2100°F). They are also useful as backup material for other types of refractories.

Manufacturing capabilities

Gemcowool® can be formed as boards, sleeves, combustion chambers and any custom shape. In addition, Refractory Specialties has a wide range of machining capabilities for added details and tight tolerances. Insulation Boards may be surface treated to provide additional erosion or chemical resistance for use in hostile environments. Gemcowool® materials can have hardware molded or installed into them to provide easy installation.

Excellent Energy Conservation

Low thermal conductivity and heat storage make Gemcowool® materials an outstanding energy saver. Thermal shock resistance permits fast cycling without cracking or spalling.

Applications include:

  • Boiler and Water heater linings for combustion areas
  • Pipe insulation
  • Gasketing
  • Heat Shielding
  • Fire Protection
  • Kiln and Industrial furnace linings
  • Flue liners
  • Backup insulation for castables, brick, etc.
  • Burner assemblies, and nozzles
  • Usable anywhere high temperature insulation is required
