Testing

Magboard is the most heavily tested MgO board on the market with performance results that are truly impressive.

• Intertek Listed as Non Combustible.
• Thoroughly tested for numerous applications and assemblies.
• Outperforms most sheathing products with a single 1/2" board.
• Exceeds building code requirements in common commercial or residential construction.
