Glass magnesium vs rock wool panels: a comparison guide
Glass magnesium panels and rock wool panels are often compared as if they were two versions of one product. They are not: glass magnesium is a magnesium board system, and rock wool is a mineral-wool filling material. This site's honest comparison is between the glass-magnesium system, the hybrid that combines the two, and the pure rock wool panel as a reference, not as a product.

The glass-magnesium side
The glass-magnesium side of this site is the hollow glass-magnesium board system — magnesium oxide, glass-fibre mesh, perlite, and non-toxic additives, with a hollow core structure — and the sandwich panels built around it, handmade and machine-made. Lairun lists the board system's uses as cleanrooms, wall partitions, ceilings, floor bases, and prefabricated buildings, and the handmade hollow panel is described in the brochure as a Class A fire material, with that attribution stated.
The standalone board's figures are stated on the magnesium oxide board page, as the product page lists them, and no raw-board figure is used in this comparison. The sandwich-panel figures that are stated belong to their own model pages, and they are not blended into a single 'glass magnesium performance' claim.
The rock wool side, as a reference
Rock wool, as a material, is described in the source material as a natural-ore, high-temperature-melted fibre material, non-combustible, with thermal and sound insulation properties. On this site, rock wool appears as the filling inside the glass-magnesium rock wool hybrid panels, at a density of 60 to 120 kg per cubic metre as required, and the source-site wording for the hybrid states A1-grade non-combustible rock wool, fire resistance above 1,000 degrees, a 50 mm fire-protection time of 74 minutes, and sound insulation meeting ISO 717 and UNI 18270/7 standards, with no test report attached.
A buyer who needs a pure rock wool panel should obtain that panel's own specification and compare it directly with the hybrid's listed construction, rather than relying on this guide's reference description. Before ordering, confirm the minimum order quantity and lead time for the model you select, and confirm the applicable humidity range for that model by inquiry.
