Product overview
Engineered for demanding thermal environments.
Ceramic fiber board is a rigid insulation product formed from high-purity alumina-silicate fibers with inorganic and organic binders selected for the required grade. Its low thermal conductivity and machinability make it suitable for linings, backup insulation and fabricated high-temperature components.
Refractory ceramic fiber (RCF) identifies the alumina-silicate fiber family used in these products. Confirm the selected grade’s composition, service limits and safety data for your application.
Available specifications are confirmed for each enquiry according to application, quantity and required delivery schedule.

Ceramic Fiber Board for industrial insulation
Ceramic fiber board provides rigid, low-heat-storage insulation for industrial equipment that needs a self-supporting panel or a precisely fabricated thermal component. Compared with flexible blanket, board offers greater dimensional stability and can be cut or machined to suit furnace panels, baffles, heat shields, gaskets and backup-lining details.
Ranipa coordinates ceramic fiber board export supply from India across 1100°C, 1260°C and 1425°C classifications, including standard, high-density and high-strength formulations. Standard density configurations range from 280 to 480 kg/m³, while specialist high-strength options are available above 720 kg/m³ and above 800 kg/m³. Density, hardness, thickness and dimensions vary by grade, so mechanical duty should be considered alongside thermal performance.
Organic binder can burn out during initial heating and may produce temporary smoke or odour. Installation and commissioning procedures should therefore account for ventilation, heating rate and the equipment manufacturer’s safety requirements. Where hot-face exposure, erosion or load-bearing duty is involved, the complete lining design must be reviewed rather than selecting by temperature alone.
International buyers can specify full boards or fabricated dimensions up to the available 100 mm thickness range. Ranipa aligns technical information, order quantity, packing configuration and shipment documentation with the final commercial requirement. A drawing or dimensional schedule helps define tolerances, edge condition and inspection criteria before production.

Selection guidance
Before specifying ceramic fiber board
A complete enquiry helps align the product configuration with the service environment and export requirement.
Density and strength
Standard, high-density and high-strength boards serve different mechanical duties. Load, vibration, machining and handling requirements should be stated.
Dimensions and tolerances
Provide thickness, length, width, quantity and any critical tolerances. Fabricated shapes require a drawing and agreement on inspection criteria.
Commissioning conditions
Binder burnout, ventilation and first-heat procedure must be considered by the installer and equipment engineer before the board enters service.
Buyer questions
Ceramic Fiber Board FAQ
Which ceramic fiber board grades does Ranipa supply?
The current range covers 1100°C, 1260°C and 1425°C classifications, with standard, high-density and high-strength options subject to thickness and dimension availability.
Can ceramic fiber board be cut or machined?
Yes. Board is commonly cut and machined into panels, gaskets and fabricated insulation parts. Final tolerances and edge condition should be agreed before production.
What information is required for a board quotation?
Provide classification or operating temperature, density or strength requirement, thickness, length, width, quantity, application, destination and any drawing, packing or inspection requirement.
Is ceramic fiber board suitable as a structural component?
It is an insulation product and should not be assumed to carry structural loads. Any mechanical or load-bearing duty must be assessed and approved by the responsible design engineer.
