Cerakwool Hard Board (Ceramic Board) / Custom Cut
Up to 1260°C
Main applications
precision cut to complete your furnace lining
Key Features
Dense rigid board construction
Formed at 180–500 kg/m³ — far better compressive and impact strength than blanket
1260°C heat resistance
RCF-based ceramic board — classified at 1260°C and stable long term in 1000–1100°C service
Precision custom cutting
CNC or manual cutting — machined 1:1 from your drawings, with complex shapes made without tolerance error
Low conductivity, high efficiency
One-tenth the weight of fire brick at equivalent temperature — less structural load with better insulation
Excellent thermal shock resistance
No cracking or failure through repeated rapid heating and cooling — ideal where kiln and furnace doors open frequently
