Cerakwool Blanket 1100°C
Up to 1100°C
Main applications
- back-lining for heat-treatment furnaces
- industrial boilers and exhaust ducts
- with a practical balance of installability and thermal performance
Key Features
Classified at 1100°C
Stable in continuous service to around 900°C — the most sensible choice for general high-temperature industrial plant
Light, flexible blanket
Low heat storage allows fast heat-up and cool-down, and it installs freely over curves, corners and complex shapes
High efficiency from low conductivity
Effectively suppresses heat escape — cutting fuel cost and holding process temperature steady
Strong thermal shock resistance
No cracking or spalling through rapid temperature cycles — a reliable choice for equipment in repeated operation
Easy to work on site
Cut and shaped with a knife or shears — dramatically faster to install than conventional fire brick

Notes
- ※Where continuous service exceeds 1000°C, or alkali and moisture exposure is frequent, we recommend the 1260°C or 1430°C (HTZ) grade.
- ※Where surface strength or erosion resistance is needed, a rigidizer can be used alongside — technical consultation advised.
