ALSITHERM®

ADVANTAGES

  • Lightweight and flexible
  • Low thermal conductivity, low heat transition and low stored heat
  • Extremely thermal shock resistant
  • Resisant to high flue gas velocities
  • Easy to assemble lining systems
  • Jointless layers
  • Low shrinkage through precompression
  • Reduction of repair and downtimes

Modular systems

ALSITHERM® are lightweight construction lining systems, specially developed by Promat from ALSIFLEX® high temperature wool. They are used as an economical solution to various plant-specific factors of influence.

The systems consist of folded or cut fibre mat strips whose main fibre direction is perpendicular to the lining surface. With this arrangement, combined with precompression, high flue-gas velocities are resisted and fibre shrinkage is limited. The fixing elements are located on the cold side and their special design results in high mechanical stability.
