Handmade hollow glass-magnesium panel (Type 50)
The handmade hollow glass-magnesium panel is the handmade composite panel built around the hollow glass-magnesium core, Type 50. It is a sandwich panel, not the standalone raw board: the raw board has its own page, and its figures are stated there, on the magnesium oxide board page, as the product page lists them — not on this model page, so that no board figure is copied onto a sandwich-panel page.

What this model is
This panel takes the hollow glass-magnesium system — magnesium oxide, glass-fibre mesh, perlite, and non-toxic additives, with a hollow core structure — and builds it into a handmade sandwich panel with steel face sheets and a keel-frame construction. The hollow core is the point of the panel: it keeps the panel light while giving the panel its hollow-core behaviour, and it is the same core system that the standalone board page describes as a board.
The brochure describes this panel as a Class A fire material. That description is stated here as brochure wording for this sandwich panel model. It is not a raw-board fire rating, and it is not transferred to the standalone board page, where the fire rating is stated as the product page lists it (A1). Keeping the two statements separate is essential: a sandwich panel's brochure fire description and a raw board's verified fire rating are different documents.
The brochure also presents the magnesium sulfate glass-magnesium panel as an alternative to the oxychloride glass-magnesium panel, addressing the steel corrosion and moisture-absorption problems that the brochure attributes to chloride-ion release from oxychloride boards. That alternative framing is stated here with its brochure attribution. It is a statement about the sulfate-based glass-magnesium panel family, and it is not extended into a chloride claim for the standalone hollow board, for which no such claim is made on this site.

| Fire description | Brochure describes this sandwich panel model as a Class A fire material |
The width range matches the handmade route: 300 to 1,180 mm, with length by project, so a room with non-standard widths or planned openings can be addressed in the handmade route. The thickness options are 50 mm regular, with 75 and 100 mm custom options, the same handmade thickness set as the handmade MOS panel and the handmade MgO rock wool panel.
No other specification figure is stated for this model on this page. In particular, no density, moisture-absorption, strength, thermal-conductivity, or sound-insulation figure is stated for this sandwich panel, because the source material lists those figures only for the standalone raw board, and those figures are stated on the magnesium oxide board page, as the product page lists them. Copying a raw-board figure onto a sandwich-panel page would misattribute the figure, so it is not done.
Construction, openings, and site work
As a handmade panel, this model supports the handmade route's embedded conduits and pre-cut openings, with a keel-frame construction and easy disassembly. For a cosmetics plant or a laboratory that needs services planned into the wall, that construction route is the practical reason to choose the handmade version over the machine-made hollow panel, which is built for a uniform module and fast tongue-and-groove installation.
The joint choice — tongue-and-groove or middle-aluminium connection — should be stated in the inquiry, together with the width, thickness, and length. The joint-methods page lists the handmade joint facts without drawing dimensions, and the site team should confirm the joint detail for the room before ordering, not after delivery.
Where this model fits
The source material's customer-advice wording favours hollow magnesium panels for cosmetics plants, citing fire protection, dust protection, and seamless joints that are easy to clean, as customer advice. That advice is stated with its attribution on the cosmetics-plant application page, and it is the application context for this handmade hollow model as well as for the machine-made hollow model.
Lairun lists the hollow board system's uses as cleanrooms, wall partitions, ceilings, floor bases, and prefabricated buildings. Those listed uses frame the sandwich panel's room uses as well, but the panel selection still depends on the room: a ceiling use, a partition use, and a floor-base use impose different requirements, and the inquiry should state the use, not just the panel name.
