High-Performance Thermal Insulation and Energy Efficiency for Industrial Furnaces & Kilns
Engineered from high-purity spun alumina-silicate fibers with double-needle punching, our ceramic fiber blankets provide dependable, flexible, and lightweight refractory insulation[cite: 25, 26, 27]. Designed to prevent shell heat loss and optimize energy efficiency, they are supplied in various thicknesses, densities, and roll dimensions to suit diverse industrial applications[cite: 25, 27].
Key Advantages
- Low Thermal Conductivity: Significantly minimizes exterior furnace heat losses, delivering substantial fuel and electrical energy savings.
- Thermal Shock Resistance: Fully withstands severe heating and cooling cycles without structural cracking, flaking, or thermal fatigue.
- High Tensile Strength: Double-needling process prevents tearing, pulling, and deformation during unrolling and installation[cite: 26, 27].
- Easy Cutting and Quick Installation: Cuts cleanly with utility knives and secures firmly to roofs and walls with anchor studs[cite: 25].
- Chemical Stability: Completely inert to oils, moisture, and aggressive industrial furnace atmospheres.
Available Grades
- Standard Grade: Ideal for backup linings, general industrial furnace walls, and heat ducting.
- High-Purity Grade: Formulated for demanding thermal cycles requiring low impurities and high stability.
- Zirconia Grade: Enriched with zirconia for extreme applications demanding minimal linear shrinkage.
