Fibretex 820

Fibretex 820 is a specialty purpose industrial insulation for use on high temperature furnace and hydrocracker insulation as well as for use in marine and building application for fire protection. It is a heavy duty thermal and acoustic insulation suitable for continuous operation up to 820
oC and exhibits minimal shrinkage.

Fibretex 820 Rockwool is a robust very high density insulation product for insulation in high temperature applications. It is manufactured by spinning a molten mixture of natural rock and recycled products into fine wool like fibres which are bonded together using a thermosetting resin. The product can be identified by its dark green/black appearance.

Applications

Fibretex 820 can be used in applications up to operating temperatures of 820
oC such as process temperature control, energy conservation, condensation prevention, acoustic absorption treatment and personnel protection from plant and equipment. Typical applications include:

  • lightweight furnace lining
  • fire rated bulkheads and deck-heads
  • boilers
  • eat exchangers
  • reactors
  • ovens
  • kilns
  • autoclaves
  • large diameter piping

Fibertex 820 is easily installed by impaling the batts or blankets on weld pins and securing with speed clips. Please note because of the semi-rigid nature of Fibertex 820, it does not easily conform to curved surfaces.

The un-faced surface of the Rockwool Batt or Blanket is to be applied to the hot surface to be insulated.
