CASI Nano Insulation Bricks are developed using carefully selected Al₂O₃, SiO₂, and CaO raw materials, our proprietary nano-modification technology refines these into micro-nano lightweight aggregates, achieving an optimal balance of low thermal conductivity and high strength.
The CASI Nano Insulation Brick is the ideal solution for:
– Thermal furnaces & kilns requiring energy – efficient insulation
– Industrial heating equipment where weight reduction is critical
– High-precision thermal systems demanding uniform thermal performance
Used as backup insulation of many industrial furnaces such as roller hearth kiln, tunnel kiln, glass tank, hot blast stove, reheating furnace, aluminum smelter, carbon baking furnace, flue, hot wind duct, etc
By combining the high strength of traditional refractories with the ultra-low thermal conductivity of insulation wool, our product opens new possibilities for furnace design, energy savings, and structural optimization, providing a reliable material foundation for next-generation thermal engineering.
Applications: Insulation and working layers of roller kiln walls and floors
Replacement Products: Lightweight mullite bricks, lightweight fireclay bricks, ceramic fiber boards.
Advantages: Lower outer wall temperature, more energy-efficient, lighter thermal equipment, higher cost-effectiveness
Applications: Insulation layers of large hot air ducts
Replacement Products: Lightweight clay bricks, high alumina lightweight bricks
Advantages: Lower outer wall temperature, more energy-efficient, lighter thermal equipment, higher cost-effectiveness
