Machine-made MgO rock wool panel (Type 50, 1150 type)
The machine-made MgO rock wool panel is the machine-made glass-magnesium rock wool tongue-and-groove panel, Type 50, 1150 type. It is the hybrid panel of this site: a hollow glass-magnesium board filled with rock wool, combining the magnesium board system with a rock wool filling for higher fire-protection and sound-insulation requirements.

What this model is
The listed description for this model is short and precise: a hollow glass-magnesium board filled with rock wool, with fire protection and sound insulation raised, for projects with higher requirements in those two areas. The hybrid construction is the point: neither the board alone nor the rock wool alone is the product. The product is the combination, in a tongue-and-groove panel, at the machine-made module.
The source-site product wording for the MGO rock wool panel 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. A buyer who will rely on the 74-minute figure or the sound-insulation standards for a project should ask for the test documents for this model at inquiry, and should not treat this page as the test document.
The same source-site wording describes the rock wool fibres as perpendicular to the metal panel, with high-density strip rock wool staggered along the length of the board, giving the machine-made glass-magnesium rock wool panel good load-bearing capacity. That fibre description is also source-site product wording, and it explains why the hybrid is presented for higher-requirement projects rather than as a general-purpose panel.
Listed dimensions and specification
| Item | Listed value |
|---|---|
| Type | Type 50, machine-made, 1150 type |
| Core | Hollow glass-magnesium board filled with rock wool, as listed |
| Regular width | 1,150 mm |
| Thickness range | 50 to 150 mm |
| Length | By project |
| Rock wool density | 60 to 120 kg per cubic metre, as required by the customer |
| Joint | Tongue-and-groove installation |
| Fire and sound wording | Source-site product wording: A1-grade non-combustible rock wool; fire resistance above 1,000 degrees; 50 mm fire-protection time 74 minutes; sound insulation meets ISO 717 and UNI 18270/7 standards (no test report attached on this site) |
The rock wool density range is stated as a customer-requirement range, not as a single density. The inquiry must state the density required, or ask which density the supplier recommends for the room's fire and sound-insulation requirements, because a density at one end of the range is not the same panel as a density at the other end.
Length is by project, and thickness is a range, so the inquiry must state both. A 50 mm panel and a 150 mm panel in this model are not interchangeable, and the 74-minute fire-protection figure quoted above belongs to the 50 mm thickness in the source-site wording. It must not be copied onto other thicknesses.
Construction and site work
As a machine-made panel, this model is continuously roll-formed with colour-coated or stainless-steel face sheets, and it installs by tongue-and-groove joint at the 1150 mm module. That construction suits regular room layouts where installation speed matters, and it contrasts with the handmade MgO rock wool panel, which offers custom widths, embedded conduits, and pre-cut openings for irregular layouts.
For a room where the fire-protection or sound-insulation requirement is the deciding factor, the hybrid construction is the reason to select this model over a single-core magnesium panel. For a room where the deciding factor is width flexibility or planned openings, the handmade hybrid should be compared instead. The handmade-versus-machine-made guide sets out that comparison.
Where this model fits
This model fits projects with higher fire-protection and sound-insulation requirements, as its listed selling point states. The Guangzhou Quaker project, listed as using magnesium-oxide rock wool panels and hollow magnesium-oxide panels, is a project-listing example of the rock wool hybrid family in a chemical-industry project, and its project page states only the listed project facts.
Pure rock wool panels are not products of this site, and this hybrid page does not present them as such. A buyer comparing this hybrid with a pure rock wool panel should compare the hybrid's listed combination against the pure panel's own specification, on the pure panel's own terms, not from this page.
