In modern industrial operations, achieving high-temperature insulation, energy efficiency, and reliable furnace performance is essential. Traditional refractory materials, such as fire bricks, castables, and standard fiber blankets, often fall short when facing higher production demands and stricter energy regulations. Ceramic fiber paper has emerged as a high-performance solution, offering flexible, lightweight, and durable insulation for industrial furnaces, kilns, boilers, and other high-temperature systems.
Highland Refractory provides premium ceramic fiber paper designed to meet the strict demands of global metallurgical, glass, ceramic, and heat treatment industries. With decades of expertise in refractory materials, we ensure our fiber paper delivers optimal insulation performance, safety, and long-term durability.
Ceramic fiber paper is a thin, flexible insulation material made from high-purity alumina and silica fibers, forming a lightweight sheet that can withstand extreme heat. Unlike ceramic fiber blankets, which are bulkier, the paper is thin, compressible, and easy to shape, making it ideal for applications where tight tolerances and thin insulation layers are required.
Key features:
High-temperature tolerance: 1260–1600°C (certain grades up to 1650°C)
Low thermal conductivity: Efficiently reduces heat loss
Lightweight and flexible: Easy to cut, bend, and layer
Chemical inertness: Resistant to acids, alkalis, and oxidation
Durable: Provides long-term thermal insulation under repeated heating cycles
Ceramic fiber paper serves a wide range of industrial applications due to its versatility, flexibility, and thermal efficiency. Highland Refractory’s ceramic fiber paper is widely used across steel, aluminum, glass, ceramic, and heat treatment industries.
One of the most common uses of ceramic fiber paper is lining high-temperature industrial furnaces. It can be applied as a thin insulation layer, complementing other refractory materials like fiber blankets or modules. Benefits include:
Reducing heat loss and increasing furnace efficiency
Maintaining uniform temperature inside the furnace
Reducing structural load due to lightweight design
Easy replacement or maintenance when layered insulation is needed
Typical applications:
Steel reheating furnaces
Aluminum melting furnaces
Glass kilns and melting furnaces
Ceramic kilns for pottery and tile production
Ceramic fiber paper can be used to seal gaps and joints in high-temperature industrial equipment. Its flexibility allows it to conform to uneven surfaces, making it ideal for:
Furnace doors and access ports
Expansion joints in kilns and pipes
Sealing flanges and equipment interfaces
The material’s high-temperature resistance ensures these gaskets maintain their properties under extreme heat, preventing energy loss and protecting furnace integrity.
In glass and ceramic production, thermal stability and uniform temperature are critical for product quality. Ceramic fiber paper provides:
Thin, highly insulating layers that protect the kiln shell
Efficient heat retention to reduce energy consumption
Easy customization to fit kiln geometries, corners, and curves
Highland Refractory’s fiber paper is often combined with modules or blankets to achieve multi-layer insulation for maximum efficiency.
In addition to furnaces and kilns, ceramic fiber paper is widely used in:
Boilers and heat exchangers
Thermal processing equipment for metallurgy and chemical processes
Secondary insulation layers where space is limited
By layering fiber paper sheets, engineers can adjust insulation thickness without increasing weight or reducing space for internal components.
Industrial equipment expands and contracts with heat. Ceramic fiber paper acts as a flexible insulation layer that accommodates thermal expansion, preventing damage to:
Kiln and furnace walls
Pipes and ducting systems
High-temperature equipment with repeated thermal cycling
Ceramic fiber paper can withstand temperatures from 1260°C up to 1600°C, with special grades reaching 1650°C. This makes it suitable for applications like:
Metal melting and forging furnaces
Glass fusing kilns
Ceramic sintering kilns
By reducing heat loss, ceramic fiber paper improves energy efficiency, lowering fuel costs and maintaining stable furnace temperatures. Its low thermal conductivity also reduces surface temperatures, improving operator safety.
Unlike refractory bricks or castables, ceramic fiber paper is thin, lightweight, and easy to handle. It can be:
Cut into sheets
Layered for desired insulation thickness
Rolled or compressed to fit complex geometries
The material is resistant to acids, alkalis, and oxidation, making it suitable for industrial environments with corrosive gases or chemicals.
Highland Refractory’s ceramic fiber paper maintains insulation properties over repeated heating cycles, offering a long service life with minimal maintenance.
Its flexibility allows for fast, labor-saving installation, reducing furnace downtime. Pre-cut sheets and custom sizes are available from Highland Refractory for complex industrial layouts.

Insight: Ceramic fiber paper excels in thin-layer insulation, fast installation, and energy efficiency, while castables and bricks are more suitable for structural linings.
To maximize performance:
Cutting: Use ceramic scissors or knives for precision.
Layering: Stack sheets for desired thickness; compress lightly to minimize gaps.
Anchoring: Secure using mechanical anchors, clips, or steel frames as needed.
Storage: Keep sheets dry and free from contamination.
Safety: Wear gloves and masks to prevent dust irritation.
