Thanks to state-of-the-art manufacturing technology and selection of the best raw materials our chimney inserts are distinguished with:

  • Resistance to high temperatures and temperature changes
  • Virtually unlimited lifespan
  • Resistance to combustion products and acid condensates
  • Low gas and water permeability
