Magnesium Oxide Board Uses
Six application paths. Three purpose-built MgO board systems.
Sulfycor magnesium oxysulfate boards are selected by their role in the assembly: non-woven finish for sheathing, ductwork and SIP; sanded boards for subfloor and underlayment; decorative panels for finished interior walls.
Applications
Each application has different surface, thickness, edge, fixing and documentation requirements. Start with the project layer, then review the corresponding product series.
Non-Woven Finish
Interior or exterior wall sheathing within a specified wall system.
Sanded Surface
Supporting board layers beneath the selected finished floor system.
Panel System
MgO-faced structural insulated panels for project-specific assemblies.
Non-Woven Finish
Board components for HVAC and smoke-exhaust duct systems requiring project review.
Multi-Layer Selection
Select different MgO board systems for sheathing, SIP, subfloor and finished walls.
Finished Interior Wall
Melamine-paper or HPL-faced MgO panels for interior and modular-house walls.
Selection Guide
The generic term “MgO board” does not identify the required surface, duty or complete assembly. Confirm the application first.
| Project need | Recommended series | Primary role |
|---|---|---|
| Sheathing, ductwork, SIP | Non-Woven Finish | Ready-faced construction board |
| Subfloor and underlayment | Sanded Board | Supporting board below the finished floor |
| Finished interior wall | Decorative Wall Board | Melamine-paper or HPL face |
Quality Evidence
Independent reports identify the tested Sulfycor board samples and measured results. Documentation is matched to the board type, thickness and intended application before quotation.
