Nutec Fibratec* macromodule is a prefabricated insulation system, for use in high temperature industrial furnaces, laddle covers, kiln doors and others.

Nutec Fibratec*Macromodulos* is a prefabricated module, continuously shaped with ceramic fiber blanket folded and anchored to an expanded metal sheet.

  • Unbeatable fuel savings.
  • Monolithic integrity, no seams, no foil.
  • Attached to expanded metal.
  • No curing or dry-out time required.
  • More uniform heat distribution for improved product quality
  • Low thermal mass means faster heat up and cool down.
  • High resistance to thermal shock - no spilling.
  • Cooler ambient temperatures and low combustion noise provide a comfortable environment for personnel in the process area.
  • Sizes almost unlimited.
  • Shorter downtime - products arrive at your plant ready to install.

Typical Applications

Industrial Furnaces:
  • Walls
  • Roof
  • Doors
  • Ladle Cove

All data represents typical results of standard tests conducted under controlled conditions. As such, the information is intended only as a general guide for specifications and design estimates.

HP and HTZ are manufactured by the spun process. This process produces long fibers that give our products more strength.

RT & HT are manufactured by the blown process which produces a finer, softer blanket ideal for applications such as molding around investment casting forms.
