In industrial operations where high-temperature insulation, energy efficiency, and durability are essential, choosing the right refractory material is critical. Ceramic fiber board offers a lightweight, flexible, and high-performance solution for furnaces, kilns, and heat-treatment equipment.
Highland Refractory provides premium ceramic fiber board engineered to meet industrial demands worldwide. With exceptional thermal resistance, low heat conductivity, and easy installation, our ceramic fiber boards are ideal for multiple applications across metallurgy, glass, ceramics, and laboratory furnaces.
Ceramic fiber board is a thin, high-temperature insulation board made from high-purity alumina and silica fibers. Unlike ceramic fiber blankets, boards are rigid yet slightly flexible, making them suitable for structural insulation, high-temperature lining, and precise layering applications.
Key Features:
Operating temperature: 1260–1600°C, with specialty grades up to 1650°C
Lightweight and rigid structure for ease of installation
Low thermal conductivity for energy efficiency
Chemically inert, resistant to acids, alkalis, and oxidation
Can be cut, drilled, and shaped for complex industrial configurations
Ceramic fiber boards typically come in thicknesses of 3–25 mm, with standard sizes of 600×600 mm, and can be customized for specific furnace geometries.
Highland Refractory’s ceramic fiber boards are widely used across industries for applications requiring high-temperature insulation, energy conservation, and precise fitting.
Ceramic fiber boards provide an efficient insulation layer in high-temperature industrial furnaces. They help:
Maintain consistent process temperatures
Reduce heat loss
Protect furnace shells from thermal stress
Typical Applications:
Steel reheating and holding furnaces
Aluminum melting furnaces
Glass melting kilns
Ceramic firing kilns
Benefits:
High thermal resistance
Reduced operational costs through energy efficiency
Lightweight, minimizing load on furnace structures
Ceramic fiber boards are used as thermal barriers in:
Heat treatment furnaces
Boilers and heat exchangers
High-temperature pipelines
They provide uniform insulation, prevent heat damage, and reduce energy loss. Their rigid yet manageable structure allows for precise installation in confined or complex spaces.
The flexibility and compressibility of ceramic fiber boards make them ideal for high-temperature gaskets and expansion joints. Applications include:
Furnace doors and access panels
Kiln expansion joints
Flanges and ducting in metallurgical and chemical plants
The boards absorb thermal expansion while maintaining a durable, heat-resistant seal.
Ceramic fiber boards are often used as supplementary insulation in areas where space is limited or precise thickness control is required:
Layered over refractory bricks or castable linings
Applied to protect structural steel from radiant heat
Integrated with ceramic fiber modules or blankets for multi-layer insulation systems
Highland Refractory’s boards are ideal for:
Glass fusing kilns
Ceramic sintering equipment
Metallurgical holding furnaces
Laboratory furnaces and pilot plants
These applications benefit from lightweight, low-conductivity boards that can be cut, drilled, or layered for maximum efficiency.
Ceramic fiber boards withstand continuous operating temperatures from 1260°C to 1600°C, with specialty grades capable of up to 1650°C. This makes them suitable for most industrial furnaces, kilns, and heat-treatment equipment.
With a thermal conductivity of 0.15–0.35 W/m·K, ceramic fiber boards minimize heat loss, improve energy efficiency, and reduce surface temperatures, enhancing operator safety.
Boards are rigid yet relatively lightweight, allowing for:
Easy handling and cutting
Installation in vertical or horizontal positions without sagging
Layering for customized insulation thickness
Ceramic fiber boards are chemically inert, resistant to acidic and alkaline fumes, oxidation, and corrosion. This ensures long-term performance in harsh industrial environments.
Highland Refractory’s boards maintain insulation integrity over repeated heating cycles, ensuring minimal maintenance and consistent thermal performance.
Compared with heavy castables or bricks, ceramic fiber boards allow fast and precise installation. Pre-cut or custom-sized boards provided by Highland Refractory simplify installation, reduce downtime, and improve overall operational efficiency.
