The non-corrosive nature of premium MgO subfloor panels relies entirely on their chemical matrix:
Magnesium Sulfate Formulation (): By replacing Magnesium Chloride () with Magnesium Sulfate, the manufacturing process eliminates free chloride ions.
Zero Leaching: Sulfate-based boards do not exhibit hygroscopic (moisture-attracting) pulling of ambient water in high-humidity zones. Because the board stays dry internally and lacks chlorides, it will not degrade or corrode steel joists, light-gauge steel framing, or subfloor fasteners.
Acoustic & Structural Integrity: The resulting matrix is ...
