MgO sandwich panel: magnesium oxide sandwich panels, including the rock wool hybrid
MgO expands to magnesium oxide. This page is the abbreviated-form category page for magnesium oxide sandwich panels, and it is the home on this site for the glass-magnesium rock wool hybrid panels: the machine-made MgO rock wool panel and the handmade MgO rock wool panel, in which a glass-magnesium board is combined with rock wool filling.

The hybrid panels
The machine-made MgO rock wool panel (Type 50, 1150 type) is listed at a regular width of 1,150 mm and a thickness range of 50 to 150 mm, with rock wool density of 60 to 120 kg per cubic metre as required by the customer. Its selling point, as listed, is a hollow glass-magnesium board filled with rock wool, raising fire protection and sound insulation for projects with higher requirements in those two areas.
The handmade MgO rock wool panel (Type 50) lists its full layer sequence, from upper steel sheet through fire-resistant glass-magnesium board and rock wool to lower steel sheet, with length and width customisable, embedded conduits, and pre-cut openings. It is listed as suitable for purification plants with high fire-protection and high-cleanliness requirements, with easy installation and a neat appearance.
The source site's MGO rock wool panel wording states that the rock wool is A1-grade non-combustible material, that fire resistance exceeds 1,000 degrees, that the fire-protection time of a 50 mm thick panel is 74 minutes, and that sound insulation meets ISO 717 and UNI 18270/7 standards. That wording is quoted here as source-site product wording, and no test report is attached to it on this site, so it is not presented as a test conclusion.
What is not on this page
Pure rock wool panels are not products of this site and are not given product pages here. Rock wool appears on this page only as the filling inside a glass-magnesium hybrid panel, which is a magnesium-system product. A buyer who needs a pure rock wool panel should compare that panel on its own terms elsewhere, not from this page.
