Hollow glass-magnesium panel explainer
A hollow glass-magnesium panel is a panel built around a hollow glass-magnesium core: a magnesium board system with a hollow core structure, used both as a standalone board and inside sandwich panels. This explainer describes the core, the structure, and the listed uses, and it states only specification figures verified against the product page for the standalone board.

Composition and structure, as listed
The board system's 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. The hollow structure is the defining feature: the board is not a solid slab, and its behaviour as a panel core follows from the hollow form, not from a solid-core assumption.
As a sandwich panel, the hollow core appears in two models: the handmade hollow glass-magnesium panel (Type 50), at 300 to 1,180 mm width and 50 mm regular thickness with 75 and 100 mm custom options, and the machine-made hollow glass-magnesium panel (Type 50, 1150 type), at the 1150-type module with 50 to 150 mm custom production. Those panel figures belong to the sandwich panels, and they are stated on the model pages, not on the board page as board figures.
Uses, and the board's listed specifications
Lairun lists the hollow board system's uses as cleanrooms, wall partitions, ceilings, floor bases, and prefabricated buildings. Those uses are stated with that attribution, and they frame the panel's room uses as well, with the room use stated explicitly at inquiry.
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. Before ordering, confirm the minimum order quantity and lead time for the model you select.
