Glass magnesium board: the material page
Glass magnesium board is the material name for the magnesium-oxide board layer that appears in two places on this site: as a fire-resistant glass-magnesium board layer inside handmade panels, and as the hollow glass-magnesium board system that stands alone as a board product. This page is the material page for both, and it keeps the two roles distinct.

The board layer inside handmade panels
The handmade MgO rock wool panel lists its layer sequence in full: upper steel sheet, eco-friendly adhesive, upper fire-resistant glass-magnesium board, fire-resistant glass-magnesium keel, eco-friendly adhesive, fire-resistant rock wool, eco-friendly adhesive, ABS corner piece, galvanised keel, lower fire-resistant glass-magnesium board, eco-friendly adhesive, and lower steel sheet. The glass-magnesium board layer is doing fire-resistant work inside that sequence, and it is named as a layer, not as a standalone product, in that context.
That layer sequence matters for a buyer comparing handmade panels: the board layer, the keel, and the rock wool filling each have a named place, and the panel's fire, thermal, and sound-insulation selling points are stated for the panel as a whole on its model page, not assigned to the board layer alone.
The hollow glass-magnesium board system
As a standalone system, the hollow glass-magnesium board is the only independent board product on this site, and its page is the magnesium oxide board page. Its material composition, as listed, is magnesium oxide, glass-fibre mesh, perlite, and non-toxic additives, with a hollow core structure. Lairun lists its uses as cleanrooms, wall partitions, ceilings, floor bases, and prefabricated buildings.
The standalone board's specifications, as the product page lists them, are stated in the table below; the same table appears on the magnesium oxide board page.

Support wordings for this page include hollow glass magnesium panel and hollow glass magnesium sandwich panel as search wordings. They are vocabulary for this material page, not separate products, and the hollow-panel explainer in the blog explains the hollow board in the same limited terms.
