Insulation Boards

Insulation Boards

High temperature insulating Fibre Boards and Shapes are typically used for thermal management and the customization options are broad. We offer standard formulations, sizes and shapes typically found and required in the market.  In addition, we have the capability to make custom forms to precise requirements.

Our range comprises three fibre grades:

  • Alkaline Earth Silicate Fibre (AES) boards and shapes made from our unique low bio-persistence Superwool® fibre
  • Refractory Ceramic Fibre (RCF) also known as Alumino Silicate Wool (ASW) boards and shapes made from Kaowool®, Cerafibre®, Cerachem®  and Cerachrome®
  • Polycrystalline Fibre (PCW) boards and shapes made from Alphawool®

AES (Superwool)

Our Superwool Fibre Boards and shapes can be designed to be rigid, self-supporting insulation or manufactured into a flexible solution, with both providing exceptional performance-to-weight ratio and are resistant to most chemical attacks. Superwool Fibre Boards and Shapes offer a potential for space savings of up to 50% thickness when replacing insulating firebricks or castables. 


All our RCF Fibre Boards and Shapes can be machined to tight tolerances to create standard shapes or custom designs to meet individual needs. 

Kaowool Fibre Boards and Shapes feature low thermal conductivity, excellent thermal shock resistance and low heat storage for effective energy savings.

These Fibre Boards and Shapes are mechanically strong and dimensionally stable up to 1649°C. 


Our PCW fibres are ideal for high temperature and chemically aggressive applications. These fibres are manufactured by sol-gel technology using processes specifically designed to produce fibres of defined dimensions. 

Alphawool and Denka boards and shapes are more resistant to acid and alkaline solutions than conventional alumino-silicate fibre products and have exceptionally good thermal insulation characteristics. They are classified to 1600°C. They are both offered as rigid or flexible products.
