Ceramic & Alumino-Silicate Fibre Boards – Hub for High-Temperature Insulating Boards up to 1650 °C
High-temperature insulating boards from 1200 to 1650 °C – vacuum-formed from ceramic fibre (RCF), AES or polycrystalline fibre. Duraboard®, Kaowool®, Superwool® and more.
SENN Gruppe supplies the complete range of refractory insulating boards made from ceramic fibre (RCF), aluminosilicate wool (ASW), low-biopersistent AES wool and polycrystalline fibre – from Alkegen® (formerly Unifrax®) and Morgan Thermal Ceramics. Vacuum-formed boards cover classification temperatures from 1100 °C (Morgan Superwool® HT LB, flexible) through 1200 °C (Superwool® Plus Board, AES / REACH-friendly), 1260 °C (Fiberfrax® Duraboard® RG/LD/HD, Kaowool® 1260, Ceraboard® 1260), 1425 °C (Ceraboard® 1425) up to 1649 °C (Duraboard® 3000) and 1650 °C (Kaowool® 1650 MD). For even higher temperatures and without organic binders we carry the Morgan Inorganic I-Boards (I-A5 up to 1621 °C).
