Custom-made ceramic fiber vacuum-formed shapes for specific industrial furnace and equipment geometries.
Custom-manufactured through vacuum forming to meet specific dimensional and geometric requirements for unique insulation applications, burner blocks, and custom furnace components.
Vacuum-formed ceramic fiber special shapes are custom-moulded rigid parts made from ceramic fibre slurry, used where a precise geometry — burner blocks, peep sights, kiln furniture — must survive high heat without cracking.

mullite fiber board — Built for laboratory furnaces, specialty glass and advanced materials processing where standard refractory fibre would already be failing.
ceramic fiber paper — Thin, uniform and flexible refractory paper for gaskets, expansion joints and sealing where every millimetre of thickness matters.
calsil board — The reference choice for kiln and furnace linings where a hard block must resist mechanical load, thermal cycling and direct flame contact at the same time.

Ceramic fiber insulation withstands temperatures from 1100°C to 1430°C, depending on the grade. Standard (ST) and High-Purity (HP) grades are rated for 1260°C, while High-Alumina (HA) handles 1360°C and Zirconia (HZ) reaches 1430°C. Always match the grade to your specific operating temperature.
The grades differ mainly in alumina (Al₂O₃) content and temperature rating. COM (1100°C) is the economy grade. ST (1260°C) is the standard industrial grade. HP (1260°C) offers higher purity with lower shot content. HA (1360°C) has higher alumina for superior thermal stability. HZ (1430°C) contains zirconia for the highest temperature resistance.
Yes. Our ceramic fiber products are 100% asbestos-free and manufactured to international safety standards. They are classified as non-carcinogenic under EU Directive 97/69/EC. We recommend standard PPE (gloves, dust mask) during handling, as with any fibrous insulation material.
Ceramic fiber blanket can be cut to size with a utility knife and secured using high-temperature anchors, pins, or stud welding. For furnace linings, a layered installation is recommended. For pipe insulation, wrap and secure with stainless steel bands. Full installation guidance and technical support are provided with every order.
Ceramic fiber is widely used in industrial furnaces, kilns, boilers, petrochemical heaters, power generation equipment, incinerators, and building fire protection systems. It is ideal for backup insulation, expansion joints, door seals, and high-temperature gaskets.
