What Is a Magnesium Oxide Rock Wool Cleanroom Panel?
A magnesium oxide rock wool cleanroom panel uses rigid MgO sulfate boards around a high-density mineral wool core. The inorganic construction combines A1 fire performance, anti-sag strength, moisture resistance, insulation and acoustic control in one cleanroom panel.
Mineral-based facing and core resist rust, mould, moisture and daily disinfection. This makes the panel suitable for fire compartments, GMP suites, laboratories and wash-down areas within Wonclean's cleanroom wall systems.
As an experienced cleanroom panel manufacturer, Wonclean produces every board on a high-precision automated line and can supply matching ceiling panels, doors and windows for a fully sealed, flush-finish enclosure.

Panel Core Comparison — Choose the Right Core
| Core type | Fire class | Thermal / acoustic | Best for |
|---|---|---|---|
| MgO + Rock wool (this panel) | A1 facing / A-grade core | Excellent fire, very good acoustic, moisture-proof | Fire compartments, GMP, wash-down rooms |
| Steel + Rock wool | A-grade | Strong fire & acoustic, metal facing | General cleanroom walls |
| PIR / PU | B1 | Best thermal insulation, lighter | Cold rooms, temperature control |
| EPS | B1 / B2 | Economical, lightweight | Budget / low-risk areas |
| Aluminum honeycomb | A-grade | Very flat & light, high rigidity | Ceilings, high-grade flush walls |
MgO Facing vs Color-Steel Facing
| Feature | MgO Rock Wool Panel | Color-Steel Rock Wool Panel |
|---|---|---|
| Facing combustibility | A1 non-combustible mineral board | Non-combustible steel + organic paint |
| Corrosion / rust | Will not rust — fully inorganic | Can corrode if coating is scratched |
| Humidity / mould | Mould-proof, zero swelling | Good, surface-coating dependent |
| Surface finish options | Coated MgO, HPL, PVC or painted | Pre-painted steel colors |
Where MgO Rock Wool Panels Are Used
From Spec to Site — 4 Steps
Expert FAQ on MgO Rock Wool Panels
How is this better than a standard color-steel rock wool panel?
Both use an A-grade rock wool core. The A1 MgO facing adds rust, mould and moisture resistance for fire-rated, GMP and wet areas, with HPL, PVC or painted finish options.
What fire rating do you offer, and can you provide certificates?
The MgO facing and rock wool core are non-combustible. Fire resistance can reach 1–2 hours by thickness, with third-party reports available.
Can the panel be used as a walkable ceiling?
Yes. With suitable framing, the reinforced panel can form an accessible ceiling. Share the span and load for sizing.
How do you keep panels flat and prevent deformation in transit?
Panels meet a ≤ 2 mm/2 m flatness target and ship film-wrapped with edge protection and plywood crating.
Which surface finishes and colors are available?
Coated MgO, HPL, PVC film and painted finishes are available in RAL or custom colors, with batch control for consistency.
What are the lead time and minimum order?
Typical lead time is 10–15 days for samples or small orders and 20–25 days for a full container, subject to specification.
