Calcium silicate board is a versatile material known for its thermal insulation, fire resistance, and durability. However, not all calcium silicate boards are the same—they are divided into high-temperature industrial use and general construction use. At Kerui Refractory, we specialize in high-performance calcium silicate boards designed for extreme heat and demanding industrial environments.
Understanding the differences between these two types—including their temperature resistance, applications, and material properties—will help you select the best solution for your needs.
Designed to withstand up to 1100°C, high-temperature calcium silicate boards are essential in industries where heat resistance and insulation are critical.
Key Applications:
✔ Industrial furnaces & kilns
✔ Petrochemical & power plants
✔ Steel ladles & refractory backup layers
✔ High-temperature pipe & duct insulation
Why Choose High-Temp Calcium Silicate Board?
✅ Extreme heat resistance (1000°C+)
✅ Low thermal conductivity for energy efficiency
✅ Custom shapes (pipes, curved panels, grooved blocks)
✅ Mechanical strength under thermal stress
At Kerui Refractory, we provide custom-cut calcium silicate boards for complex insulation needs, including kiln linings, pipe sections, and furnace insulation.
Used primarily in building interiors, these boards focus on fireproofing, moisture resistance, and easy installation rather than extreme heat insulation.
Common Uses:
✔ Fire-rated walls & ceilings
✔ HVAC duct enclosures
✔ Prefab building panels
✔ Moisture-resistant wall linings
Key Benefits:
✅ Fire resistance up to 650°C
✅ Lightweight & easy to install
✅ Paintable & smooth finish
✅ Mold & moisture resistant
Feature | High-Temp Use | Construction Use |
---|---|---|
Operating Temperature | 650°C–1100°C (some up to 1200°C) | Typically ≤300°C |
Density | Higher (200–1000 kg/m³) | Lower (150–400 kg/m³) |
Strength & Durability | Optimized for thermal shock | Lightweight for easy handling |
Shapes & Customization | Boards, pipe sections, elbows, curved panels, even complex shapes like kiln access blocks | Mostly flat boards and standard wall panels |
Typical Thickness | 25–100 mm | 6–20 mm |
Size Range | Industrial boards often 1000×500 mm, 1200×600 mm; pipe sections sized to match outer pipe diameters | Standard wall panel sizes (e.g., 2440×1220 mm) |
Shapes & Customization | Boards, pipe sections, elbows, curved panels, even complex shapes like kiln access blocks | Mostly flat boards and standard wall panels |
✔ For temperatures above 600°C, always choose high-temperature calcium silicate board.
✔ Need custom shapes? Industrial-grade boards can be molded into pipes, arches, and complex insulation blocks.
✔ For fireproof walls & ceilings, construction-grade boards are more cost-effective.
