Excellent handling / processing strength.


Heat resistance

Resistance to temperature changes & resistance to chemicals.



Low thermal conductivity & heat storage.


Our ceramic fiber mat 1400 ° C is a firmly needled insulation mat made from spun ceramic fiber high-temperature wool. The extra long spun high-temperature insulating wool, which is needled crosswise in a unique manufacturing process, creates a mat of exceptional strength for better handling / processing. Our ceramic fiber mat 1400 ° C is based on fibers made of aluminum silicate wool / Refractory Ceramicfibre (ASW / RCF) and is characterized by a temperature resistance of up to 1260 ° C.


  • Low thermal conductivity & heat storage
  • High tensile strength & elasticity
  • Thermal shock resistance & durability
        to chemicals
  • Good sound absorption


Mats (blankets) made of high temperature wool are needled lightweight mats made of ceramic (ASW / RCF) or biosoluble (AES) high temperature wool (HTW) and represent 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 no smoke or vapors are generated 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 from ceramic fibers, also known as ASW (aluminum silicate wool) or RCF (Refractory Ceramic Fiber), have been used for years as the standard fiber type for insulation solutions up to 1260 ° C. Consisting of a mix of aluminum oxide (Al2O3) and silicon dioxide (SiO2), the fibers offer not only high temperature resistance but also good chemical and mechanical properties.

By further refining the fiber with zirconium oxide (ZiO2) a temperature resistance of up to 1400 ° C can be achieved.
