High-Density 750kg/m³ Calcium Silicate Board (1220×2440×50mm): Industrial-Grade Thermal Insulation Solution
In demanding industrial environments where fire resistance, thermal insulation, and structural strength are critical, high-density calcium silicate boards stand out as a reliable solution. The 750kg/m³ calcium silicate board in large size 1220×2440×50mm is specifically engineered for heavy-duty applications requiring durability and long-term performance.
What Is 750kg/m³ Calcium Silicate Board?
Calcium silicate board (CaSi board) is an advanced insulation material made from silica, lime, and reinforcing fibers, processed under high temperature and pressure. With a density of 750kg/m³, this board offers an optimal balance between:
Mechanical strength
Thermal insulation performance
Fire resistance
Compared to lower-density boards, the 750kg/m³ variant provides enhanced load-bearing capacity while maintaining excellent insulation properties.
Key Specifications
Density: 750 kg/m³
Size: 1220 × 2440 mm (standard large panel)
Thickness: 50 mm
Temperature Resistance: Up to 1000°C (depending on grade)
Thermal Conductivity: Low, ensuring efficient insulation
Fire Rating: Non-combustible (A1 class)
Advantages of Large Size (1220×2440mm)
The large panel format offers several installation and cost advantages:
Reduced joints, improving thermal efficiency
Faster installation, saving labor costs
Better structural integrity for large surfaces
Cleaner finish in visible applications
This makes it ideal for industrial insulation systems, ductwork, and fireproof panels.
Applications
The 750kg/m³ calcium silicate board is widely used in:
🔥 Fireproofing Systems
Fire-rated walls and partitions
Fire doors and escape routes
Cable tunnel protection
🏭 Industrial Insulation
Furnace linings
Kilns and boilers
Petrochemical equipment
🌬️ HVAC & Duct Systems
Self-supporting air ducts
Smoke exhaust systems
High-temperature ventilation
⚡ Energy & Power Sector
Power plant insulation
Battery energy storage system (BESS) fire protection
Electrical equipment backing boards
Why Choose 750kg/m³ Over 600kg or 1000kg?
Choosing the right density is critical:
600kg/m³: Better insulation, lower strength
750kg/m³: Balanced performance (most versatile) ✅
1000kg/m³+: High strength, higher cost, less insulation
For most industrial and fireproof applications, 750kg/m³ is the optimal choice.
Performance Benefits
✅ Excellent thermal insulation
✅ Superior fire resistance (non-combustible)
✅ High compressive strength
✅ Moisture and corrosion resistant
✅ Long service life with minimal maintenance
Installation & Handling
Can be cut, drilled, and machined easily
Compatible with steel framing systems
Suitable for both horizontal and vertical installation
Recommended to use mechanical fixing or adhesive bonding
Conclusion
The 750kg/m³ calcium silicate board (1220×2440×50mm) is a high-performance, cost-effective solution for industries requiring reliable fireproofing and insulation. Its large size, durability, and balanced properties make it a preferred material for engineers, contractors, and industrial designers worldwide.
