Why Are Ceramic Fiber Boards Ideal for Furnace Back-Up Insulation?

In high-temperature industrial systems, insulation materials must endure not only sustained heat but also frequent thermal cycling, structural loads, and maintenance challenges. CCEWOOL® Ceramic Fiber Board is engineered precisely for such demanding environments. As a high-performance refractory fiber board, it is widely used in backup insulation layers and structural zones of furnace linings.

Ceramic fiber board - CCEWOOL®

Key Features: Designed to Meet Core Refractory Demands

  • Excellent Thermal Shock Resistance: In systems with frequent startups, door openings, and rapid temperature fluctuations, insulation must resist thermal shock without cracking or delaminating. CCEWOOL® Ceramic Fiber Board uses a homogeneously blended fiber matrix and optimized forming process to enhance fiber bonding strength and significantly reduce the risk of cracking under thermal stress.
  • High Density with Low Thermal Conductivity: Automated forming technology controls board density, delivering high compressive strength while maintaining superior insulation performance. Its low thermal conductivity helps minimize heat loss and improves the overall energy efficiency of the furnace system.
  • Precise Dimensions and Strong Installation Compatibility: Tightly controlled dimensional tolerances ensure easy and accurate installation in structural areas such as furnace walls and doors. The board’s excellent machinability also supports customization for complex geometries.

Application Case: Backup Insulation in a Glass Furnace
In one glass manufacturing plant, CCEWOOL® Ceramic Fiber Boards replaced traditional brick linings in the backup areas behind the furnace doors and walls. After multiple operational cycles, the system showed significant performance improvements:

  • Improved structural stability of the furnace doors, which remained intact under frequent thermal shock, with no spalling or cracking.
  • Reduced thermal loss, leading to greater energy efficiency across the furnace system.
  • Extended maintenance intervals, enhancing the reliability and continuity of production.

This case highlights the structural support and thermal efficiency advantages of using CCEWOOL® ceramic fibre insulation board in high-temperature systems.

With outstanding thermal shock resistance, insulation performance, and structural adaptability, CCEWOOL® Ceramic Fiber Board has become a trusted choice in a wide range of industrial furnace systems.
For customers seeking energy efficiency, structural reliability, and maintenance optimization under harsh thermal conditions, this ceramic fiber insulation board continues to prove its value across diverse projects.
