Installation notes

  1. 1Joint with zircon-based mortar to maintain corrosion resistance at seams
  2. 2Use as bottom paving beneath AZS sidewalls in glass tanks
  3. 3Low thermal expansion allows tight joints, follow OEM heat-up curve
  4. 4Excellent for areas demanding dimensional stability under thermal cycling
