Ceramic Fiber Products

How Are Ceramic Fiber Products Made?

Ceramic fiber products use thin, yet strong, metallic fibers to create heat-resistant materials. In many industries, insulation and sealing play vital roles in high-temperature activities. Cloth and other materials provide flexibility and low weight for these applications. At McNeil, we offer a myriad of ceramic fiber products to meet your refractory needs.

Ceramic fiber products are considered refractory materials, and they consist of small alumina silicate fibers. Alumina silicate provides excellent thermal resistance and low conductivity, which makes it perfect for various high-temperature applications.

To make these thin fibers, aluminum and silicon are melted together in a furnace. Once they’ve melted together, the molten metal receives quick streams of air, which cool the metal and separate it into strands. These fibers are woven together to create heat resistant fabric.

As a soft refractory, ceramic fiber blankets have the same heat resistance and conductivity of hard refractories. Lightweight and robust, these products quickly adapt to a space and are prepared to handle many heat-based applications. Use ceramic fiber blankets for:

  • Boiler insulation
  • Commercial dryer insulation
  • Expansion joints
  • Gaskets and tube seals
  • Petrochemical industry
  • Duct and pipe insulation

Thinner than ceramic fiber blankets, felts are excellent for architectural applications and aerospace and petrochemical industries. Felts are easy to cut and shape to your specifications, making them ideal for close tolerances. Offering the same thermal resistance of other refractories, this ceramic fiber cloth works for:

  • Furnace insulation
  • Fire doors
  • Heating pipes
  • Expansion joints



For a more solid material than blankets or felts, ceramic fiber boards still offer reliable thermal resistance. While they provide more rigidity than fabrics, boards are still flexible and lightweight. They have a high volume weight for increased durability and resistance. Ceramic fiber board also resists oxidation. If a board gets wet with water, oil or steam, it will return to normal when it dries.

Applications for ceramic fiber boards include:

  • Heat shields
  • Furnace lining
  • Combustion chambers
  • Gaskets and seals



Ceramic fiber paper offers flexibility for many high-temperature applications. Extremely thin and lightweight, this material maintains heat-resistance, chemical stability and corrosion resistance. Applications include:

  • Mold wrap
  • Expansion joints
  • Die-cut parts
  • Gaskets
  • Insulation



We offer various other ceramic textile products like rope, braid, cloth and tape. Much like our other ceramic fiber products, these materials provide the heat and corrosion resistance you need for high-temperature projects. They’re also resistant to mechanical vibration. Find uses for these products in:

  • Insulation
  • Sealing
  • Gasketing
