Calcium silicate board has become a staple in modern construction due to its exceptional fire resistance, moisture resistance, and thermal insulation properties. However, selecting the wrong type can lead to project delays, safety hazards, and increased costs. This guide will help you make informed decisions based on your specific needs.
1. Understand Density ClassificationsCalcium silicate boards are available in various densities, each designed for specific applications:
2. Thickness Selection Guide
- 6-8mm: Ceiling applications, light partitions
- 10-12mm: Commercial wall partitions, interior cladding
- 15-20mm: Industrial insulation, exterior walls
- 25mm: High-temperature boiler insulation, heavy-duty fire protection
3. Application-Specific Recommendations
- Industrial insulation: Choose high-density (260kg/m³+) boards with 1000°C+ heat resistance
- Commercial buildings: Opt for medium-density (200kg/m³) boards with A1 fire rating
- Wet areas: Select water-resistant calcium silicate boards with special surface treatment
- Sound insulation: Combine with rock wool insulation for enhanced acoustic performance
4. Key Performance Parameters to Check
- Fire resistance: A1-class non-combustible (EN 13501-1)
- Moisture resistance: Water absorption ≤10% (ASTM C1185)
- Thermal conductivity: ≤0.07 W/m·K for insulation applications
- Flexural strength: ≥5MPa for structural applications
5. Case Study: Steel Mill Boiler InsulationA steel mill in Germany required insulation for their 800°C boiler system. By selecting our
260kg/m³ calcium silicate boards with 1050°C heat resistance, they achieved:
- 30% energy savings compared to traditional insulation
- 10-year service life with zero maintenance
- Compliance with EU industrial safety standards
