Excellent strength during handling/processing.


Hot strength

Thermal shock resistance & resistance to chemicals.



Low thermal conductivity & heat storage.


Our Ceramic Fibre Mat 1400°Cis a tightly needled insulation mat made from spun ceramic fibre high temperature wool. The extra long spun high temperature insulation wool, cross-needled together in a unique manufacturing process, creates a mat of exceptional strength for better handling/processing. Our Ceramic Fiber Mat 1400°C is based on Aluminum Silicate Wool/Refractory Ceramicfibre (ASW/RCF) fibers and features temperature resistance 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 provide an effective solution for a wide range of thermal insulation applications. They feature 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 1260 °C. Consisting of a mix of aluminium oxide (Al2O3) and silica (SiO 2)2), the fibers offer good chemical & mechanical properties in addition to high temperature resistance.

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