Why Is Ceramic Fibre Blanket Ideal To Use When Working With Furnaces?

Ceramic fiber blankets are unique materials manufactured from sturdy spun ceramic fiber. The material has exceptional handling strength and is a well-known industry-grade material. The ceramic material is extensively used in various heat-processing applications to contain high temperatures. With their thermal and fire-resistant capabilities, ceramic fiber blankets are often used in furnaces to maximize the amount of heat. Most industries that deal with heat contention and moderation use a ceramic wool blanket.

Three Steps of Inserting A Ceramic Fiber Blanket Into A Furnace?

The three main steps include:

  • First, the furnace manufacturers cut a ceramic fiber blanket.
  • Then using a packing machine, many pieces are put together in a ceramic wool cutting module.
  • Finally, the module is fixed by using different anchoring parts.

Benefits of Using Ceramic Fiber Blanket In Furnaces

Now let us discuss the various advantages of ceramic fiber blankets.

  • Low density

The ceramic furnace lining is about 75% lighter than regular lightweight insulating fire bricks. The material is 90 to 95% lighter than any regular castable lining. Using a ceramic fiber product in a furnace can reduce the overall load of the steel structure. It can also extend the furnace’s lifespan.

  • Low heat capacity

The heat-storing capacity of ceramic fiber is about 1/10 of regular lightweight, heat-resistant lining and castable lining. The low heat capacity of the material plays a role in the startup and shutting down of the furnace. The material also has an energy-saving effect.

  • Low thermal conductivity

The furnace lining material has a low thermal conductivity, about 1/10 of the lightweight, heat-resistant lining.

  • No Oven

Once the furnace lining construction is done, you can easily use it without the oven process.

  • Good sound insulation

The ceramic fiber can lower frequencies less than 1,000 hertz when the sound wave exceeds 300 hertz. Sound insulation capacity is also essential in a furnace to reduce noise pollution.

  • Higher heat sensitivity

The heat sensitivity of the material is much better than the regular refractory bed material.Higher heat-sensitive ceramic fiber is ideal for an industrial furnace’s automatic control.

  • Great chemical stability

An aluminum silicate ceramic fiber material does not react with acidic materials. Weak acid, alkali, water, oil, and steam also do not affect the material. The material is neutral and has low acidity; it is the perfect lining material. It can also avoid corrosion of aluminum, lead, and copper.

  • Structural advantages

Nowadays, most industrial furnaces use ceramic fiber lining. The material ensures product quality and increases the yield of the furnace.

What Are Some Of The Other Uses Of Ceramic Fiber Blankets?

Ceramic Fiber Blanket manufacturers also develop the material for various other industrial purposes like:

  • They are used as lining of the stove, heating equipment, and high-temperature pipes
  • They are used for fireproofing and heat insulation of high building
  • Used as a protective layer for electric boilers and insulation for nuclear power.
  • Industries use them as heat insulation for furnace covers and doors.


Ceramic fiber blankets manufactured by Refmon Industries are widely used in various industries. The material has good thermal and heat insulation capabilities. These features make it the perfect choice for furnace lining. Most industries are trying to replace glass wool insulation with ceramic fiber lining due to its better insulation capacity.
