Magnesium Oxysulfate Board Systems
Three purpose-built MgO board systems for sheathing, ductwork, SIP, structural flooring and interior wall finishes.
Sulfycor boards use a magnesium oxysulfate cement system formed from reactive magnesium oxide, magnesium sulfate and water. Choose the board by surface finish and end use—not by the generic “MgO board” name alone.
MOQ: 1 × 20GP container

Product Range
The surface finish defines how the board is installed and what comes next in the assembly.
01 · Ready-Faced Board
For wall sheathing, fire-rated ductwork and SIP panels.
02 · Sanded Surface
For subfloor, flooring, underlayment and single-layer structural floor systems.
03 · Finished Wall Panel
MgO substrate faced with melamine paper or HPL for interior and modular-house walls.
Selection Guide
Share the assembly, required thickness and dimensions, expected load or performance criteria, quantity, destination and applicable standard. We will match the product series before preparing samples or a quotation.
| Project need | Recommended series | Surface / next step |
|---|---|---|
| Sheathing, ductwork, SIP | Non-Woven Finish | Non-woven faced |
| Subfloor, underlayment, structural floor | Sanded Board | Sanded for flooring system |
| Interior or modular-house wall finish | Decorative Wall Board | Melamine paper or HPL faced |
Material System
Sulfycor magnesium oxide boards use a magnesium oxysulfate cement system formed from reactive magnesium oxide, magnesium sulfate and water.
Conventional magnesium oxychloride boards use a system formed from magnesium oxide, magnesium chloride and water. These are different reactive magnesium salt systems with different hydration products and formulation requirements.
