Advanced ceramic fiber blanket with improved strength and lower shot content for demanding applications.
Advanced blanket with improved fiber quality, lower shot content, better tensile strength, and more consistent density for superior insulation in critical high-temperature applications.
High-purity needled ceramic fiber blanket is a binder-free, resilient mat available in standard, high-purity and high-alumina grades, making it the default choice for furnace backup lining, expansion joints and module feedstock.

ceramic fibre blanket insulation — Lightweight and easy to cut on site, it lines boiler combustion chambers, kiln bodies and high-temperature furnace shells without adding meaningful structural load.
ceramic fiber tape for pipes — Flexible enough to follow small diameters and irregular fittings without lifting, making it practical for valves and flanges as well as straight runs.
rockwool insulation board — Rigid basalt stone wool slabs, Class A1 non-combustible, water repellent and sound absorbing, with the compressive strength exterior wall systems require.

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.
