Insulating boards

Offer

The insulation boards are manufactured from aqueous suspensions of refractory fibers using the vacuum-forming method. The precisely selected layout of binders allows for the use of a minimal amount of (non-toxic) organic elements. They are removed during the first annealing, from the temperature of approximately 250 °C. As a result the board becomes completely odorless and returns to the white color. In terms of the classification temperature, we manufacture two types of boards: 1260 °C and 1430 °C.

With concern for our products, shipping of insulation boards is performed only on pallets.

 

Characteristics:

  • excellent homogeneity
  • good mechanical resistance
  • resistant to most chemicals
  • excellent volume stabilization
  • low apparent density
  • easy mechanical processing (cutting, drilling, milling)
  • stability in high temperatures
  • resistant to sudden temperature changes
  • can be used in direct contact with flames
  • low heat accumulation ratio

 

 

 Application:

  • lining of furnace vaults and walls
  • lining of combustion chambers in boilers
  • lining of boilers and water heaters
  • insulation of smelters and glass furnaces
  • dilatation, fire screens
  • general purpose thermal barrier
  • insulation of ceramic kiln cars
  • lining of heaters
  • repair and modernization of older types of furnaces
  • insulation of channels, ducts
  • insulation of the working part of hard ceramics, such as refractory bricks
  • thermal insulation in various branches of industry
