Five Key Differences Explained
1. Material and Structural Differences
Gypsum Board: Gypsum core + paper facing
Calcium Silicate Board: Homogeneous silicon-calcium material
2. Fire Performance Comparison
Gypsum board chars when exposed to fire
Calcium silicate board withstands 1000℃ without burning
No toxic gas emission during fires
3. Moisture Resistance and Durability
Gypsum board easily molds and warps when damp
Calcium silicate board suitable for wet areas like bathrooms
Passes 50 freeze-thaw cycles without damage
4. Installation Characteristics
Gypsum board easier to cut and process
Calcium silicate board requires special tools
Similar installation methods for both
5. Economic Analysis
Calcium silicate board 30-50% higher initial cost
But lower lifecycle costs
Maintenance-free features reduce long-term expenses
