Cut Energy Costs. Protect Your Equipment. Run Hotter for Longer.
If you operate furnaces, kilns, boilers, or any high-temperature process, you know that insulation is not a commodity—it is a critical engineering decision. The wrong board fails early. It cracks. It loses thermal efficiency. It forces unscheduled shutdowns that cost thousands per hour.
Our Ceramic Fiber Board is manufactured to solve these problems at the source. It delivers low thermal conductivity, excellent thermal shock resistance, and stable mechanical strength at continuous operating temperatures up to 1430°C. It is not a resold generic product. We are the factory, and every Ceramic Fiber Board we ship is produced under strict ISO 9001 quality control.
Whether you need standard boards for furnace linings or custom-machined shapes for complex hot-face applications, we supply Ceramic Fiber Board that meets your exact specification—batch after batch, shipment after shipment.
Why Your Operation Needs Our Ceramic Fiber Board
Lower Energy Consumption
The primary job of any Ceramic Fiber Board is to keep heat where it belongs. Our boards have a thermal conductivity as low as 0.08 W/m·K at 400°C, dramatically reducing heat loss through furnace walls, doors, and roofs. The result: lower fuel or electricity costs, faster heat-up cycles, and a more stable process temperature.
Survives Thermal Cycling Without Cracking
Repeated heating and cooling destroys rigid insulation materials. Our Ceramic Fiber Board is made from high-purity alumina-silicate fibers that resist thermal shock. It does not spall or crack when temperatures swing rapidly, making it ideal for batch furnaces, kiln cars, and emergency access doors.
Lightweight and Easy to Install
Compared to refractory brick or castable, Ceramic Fiber Board is up to 75% lighter. One worker can handle and cut a full-size board with simple hand tools. Installation time drops from days to hours, and the reduced structural load allows lighter furnace steelwork.
Chemically Stable in Hostile Atmospheres
This Ceramic Fiber Board resists attack from most acids, alkalis, and reducing atmospheres. It does not outgas or contaminate the products being heated, which is critical for food processing, ceramics, and precision heat treatment.
Multiple Temperature Grades for the Right Cost-Performance Balance
We manufacture Ceramic Fiber Board in standard grades rated at 1260°C, 1360°C, and 1430°C. You do not pay for a higher grade than your process requires, and you never risk under-specifying a critical lining.

Where Our Ceramic Fiber Board Is Used Every Day
Industrial Furnaces & Kilns
Backup insulation for brick linings, hot-face linings for low-mass kilns, and complete linings for heat treatment furnaces. Ceramic Fiber Board reduces heat-up time by up to 40% compared to refractory brick.
Boilers and Combustion Chambers
Used as door linings, access panel insulation, and expansion joint filler. The Ceramic Fiber Board withstands direct flame impingement in gas and oil-fired boilers while protecting the outer steel shell.
Petrochemical and Power Generation
High-temperature pipe supports, reactor insulation, and turbine exhaust systems rely on Ceramic Fiber Board for stable performance under continuous thermal load.
Glass and Ceramic Manufacturing
Kiln car tops, setter plates, and backup insulation in glass annealing lehrs. The Ceramic Fiber Board resists glass spatter and provides a clean, non-contaminating surface.
Foundries and Metal Processing
Ladle covers, tundish insulation, and heat shields for continuous casting. Our Ceramic Fiber Board handles direct contact with molten metal splash without degrading.
Appliance and Fire Protection
Backing insulation for ovens, fire doors, and high-temperature gaskets. The Ceramic Fiber Board is also used as a passive fire barrier in building and marine applications.
Custom Machining and Fabrication
One size does not fit all. That is why we offer in-house CNC machining and fabrication for Ceramic Fiber Board:
-
Cut-to-size panels — precision tolerances of ±0.5 mm
-
Holes, slots, and complex contours — machined to your CAD drawing
-
Laminated boards — bonded layers for extra thickness or density gradients
-
Surface hardening — rigidized surfaces for improved erosion resistance
-
Metal foil or mesh facing — added for mechanical protection or reflectivity
Send us your drawing or sketch. We will return a quote within 24 hours with a recommended board grade and delivery schedule.
Quality Control That Protects Your Production
Every batch of Ceramic Fiber Board is tested before release:
-
Bulk density check (ASTM C134)
-
Thermal conductivity measurement (ASTM C177)
-
Linear shrinkage at rated temperature (ASTM C356)
-
Visual inspection for cracks, delamination, and surface defects
-
Dimensional verification with calibrated instruments
We provide material certificates and test reports with every shipment. Your quality assurance team can audit our records at any time.
Packaging and Global Shipping
Ceramic Fiber Board requires careful handling to prevent edge damage and moisture absorption:
-
Boards are stacked with protective interleaving paper
-
Wrapped in moisture-barrier film
-
Packed in heavy-duty export cartons or wooden crates with edge protectors
-
Palletized and shrink-wrapped for container loading
-
Full documentation including packing list, CO, and test reports
We ship worldwide by sea, air, or express courier. Standard sizes are stocked for immediate dispatch. Custom-machined Ceramic Fiber Board typically ships within 10–15 working days.
Answers to Common B2B Questions
Q: What is the difference between 1260°C and 1430°C ceramic fiber board?
A: The higher the classification temperature, the greater the alumina content and the lower the shrinkage at extreme heat. A 1430°C Ceramic Fiber Board uses high-purity fiber that maintains strength and stability longer at elevated temperatures. Choose based on your peak operating temperature plus a safety margin.
Q: Can ceramic fiber board be used in contact with molten aluminum?
A: Standard Ceramic Fiber Board is not recommended for direct contact with molten aluminum, as the metal can react with silica in the fiber. We offer special non-wetting grades for aluminum contact applications. Please specify your exact service conditions.
Q: Does ceramic fiber board absorb moisture?
A: Yes, the porous structure of Ceramic Fiber Board can absorb moisture if exposed to high humidity or water. Store in a dry environment. If moisture is absorbed, the board can be dried gradually at 200–300°C before returning to service.
Q: Is ceramic fiber board a health hazard?
A: Like all refractory ceramic fibers, Ceramic Fiber Board can release respirable fibers if cut or abraded. We supply safety data sheets and recommend standard PPE during cutting. Bio-soluble fiber grades are available on request for applications where exposure is a concern.
Q: Do you provide samples for evaluation?
A: Yes. We offer free standard samples of Ceramic Fiber Board to qualified B2B buyers. Custom grades or machined samples may require a setup fee, refundable on your first production order.
