Magnesium oxide board: the hollow glass-magnesium board
Magnesium oxide board is the highest-volume term on this site, and this page is its board page. The standalone board product on this page is the hollow glass-magnesium board. No other standalone board type is presented as a product of this site on this page: board types that the source material does not list are not written up as products here, and no building-code certification is claimed for the board.

The board, and nothing else claimed for it
The source site lists the hollow glass-magnesium board as a standalone board product, distinct from a sandwich panel. Its material composition, as listed, is magnesium oxide, glass-fibre mesh, perlite, and non-toxic additives, with a hollow core structure that keeps the board light in weight. That composition and structure are the board facts stated on this page.
Lairun lists the following uses for the board: cleanrooms, wall partitions, ceilings, floor bases, and prefabricated buildings. Those uses are stated with that attribution, and they are uses of the board as listed, not a claim that every use suits every thickness or every project.
The board is not described here in any role beyond the listed uses, because the source material does not list it in any other role. Keeping the role list to the listed uses is deliberate: a board page that invents roles would mislead a buyer who is comparing board types.
Board and sandwich panel: how they relate
A sandwich panel is a composite: face sheets bonded to a core. A glass-magnesium board layer can serve as a face or core layer inside a sandwich panel, and the hollow glass-magnesium board can also stand alone as a board product. The two roles share a material family but they are not the same product, and this site keeps them on different pages: this page for the board, and the sandwich-panel pages for the composite panels.
When a buyer asks for a board, the questions are about the board itself: its composition, its hollow structure, and the use it is listed for. When a buyer asks for a sandwich panel, the questions move to the panel model: its width, thickness, joint, and core. The board-versus-sandwich-panel guide on this site explains that distinction in full.
Listed specifications
The product page lists the following specifications for the standalone hollow glass-magnesium board. Each figure below is stated exactly as the product page lists it, and each figure is for this standalone board only.
| Specification | Product page lists |
|---|---|
| Thickness | 49 / 74 / 99 mm |
| Size | 1200×2400 mm / 1220×2440 mm |
| Fire rating | A1 |
| Density | 700–950 kg/m³ |

No specification from the hollow magnesium sandwich panel is used in the table above, and no certification, humidity figure, price, or minimum order quantity figure is added here. Where a sandwich-panel model has its own listed specification, that specification stays on that model's own page with its own attribution.
How to use this page in an inquiry
State that you are asking about the standalone hollow glass-magnesium board, not about a sandwich panel, and state the use you have in mind from the listed uses: cleanroom, partition, ceiling, floor base, or prefabricated building. Then state the thickness and size from the listed specifications above that fit your project, and confirm the board size and quantity your project needs.
