CERAMIC FIBER BOARD - SUPERWOOL HT B

Superwool® HT B Ceramic Fibre Board is a rigid, lightweight low biopersistent insulation board designed for high-temperature glass fusing, ceramics and craft applications. Thanks to its extremely low thermal conductivity and excellent heat resistance, it is ideal for building, repairing and upgrading kilns for glass, ceramics and artistic firing. Its relatively smooth surface also makes it suitable for mould and support fabrication in glass fusing. The organic and inorganic binders burn out during first firing at approximately 350°C.

Key features
