Cerablanket™ | Ceramic Fibre Mats


Ceramic fiber | Aluminum silicate wool


Mat (blanket)


SKU: N/A Category:


Excellent handling / processing strength.

Heat resistance

Resistance to temperature changes & resistance to chemicals.


Low thermal conductivity & heat storage.


Cerablanket™ has excellent chemical stability and is made from spun fibres called Cerafiber™ ceramic fibres. The blankets have excellent dimensional stability before and after temperature application. They have both excellent thermal insulation properties and very good acoustic insulation properties. The wide range of densities and thicknesses available allows for customised thermal insulation in almost all applications. Cerablanket™ is suitable for classification temperatures up to 1260°C.


  • Excellent thermal insulation properties
  • Resistant to most chemicals
  • Excellent thermal stability
  • Low heat storage
  • Firm and at the same time elastic mats
  • Resistance to thermal shock
  • Good sound absorption


Mats (blankets) made of high temperature wool are needled lightweight mats made of ceramic (ASW/RCF) high temperature wool (HTW) and provide an effective solution for a wide range of thermal insulation applications. They are characterized by excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and therefore do not generate smoke or fumes when exposed to heat. They are available in a wide range of densities and thickness combinations, making them one of the most versatile product groups on the market.


High temperature wool made of ceramic fibersalso known as ASW (Aluminum Silicate Wool) or RCF (Refractory Ceramic Fibre), have been used for years as the standard fibre type for insulation solutions up to 1425 °C.

Morgan Thermal Ceramics

Morgan's development of low biopersistence fibers has led to a revolution in the use of fibers for high temperature insulation applications over the last 20 years. Our patented Superwool products, manufactured using ISO 9002 certified processes, are made from alkaline earth silicate (AES) composition fibers uniquely engineered to provide benefits in high temperature insulation applications.

Roll goods

Fiber mats are sold as roll goods as standard. The roll length depends on the selected thickness. As a standard width, we have 610mm wide rolls from stock. Double widths are available on request.



We manufacture molded parts according to your specifications. The roll goods are made using

  • Water jet
  • Punching
  • Plotting

brought into the right shape for you.


Fiber modules

We manufacture fiber modules according to customer specifications that are designed for the insulation requirements of industrial ovens, kilns and heating devices.
