Head-to-Head Comparison of Magnesium Oxide Board and Calcium Silicate Board
Fire Resistance and Passive Fire Protection
Both magnesium oxide boards and calcium silicate boards are excellent fireproofing materials. They meet fire protection requirements in various applications, including tunnel fire protection. However, magnesium oxide boards often outperform calcium silicate boards in fire resistance tests. These boards withstand higher temperatures and provide superior passive fire protection.
Magnesium oxide boards are non-combustible and resist temperatures up to 1200°F without releasing harmful fumes. This makes them a safer choice for areas with strict fire protection requirements. Calcium silicate boards also offer good fire resistance but may not match the performance of magnesium oxide boards in extreme conditions.
Tip: If fireproofing is your top priority, magnesium oxide boards are the better option for your ceiling needs.
Moisture Resistance
Both materials perform well in damp environments, making them suitable for kitchens, bathrooms, and other moisture-prone areas. Magnesium oxide boards, however, are often regarded as more water-resistant than calcium silicate boards. They resist water absorption more effectively, preventing damage and mold growth over time.
Material | Moisture Resistance Level | Notes |
|---|---|---|
Magnesium Oxide Board | Higher | Considered more water-resistant overall. |
Calcium Silicate Board | Moderate | Good water resistance, but less than MgO. |
If you need a ceiling material that can handle high humidity levels, magnesium oxide boards provide better long-term performance.
