Deiiang MGO rock wool composite panels are engineered exclusively for cleanroom construction. Magnesium oxide with rock wool cores form one solid wall system that is purpose‑built for controlled environments.
This single structure reaches Class A fireproof grade, resists moisture, and provides dependable thermal and acoustic insulation at the same time. Standard sizing covers an effective 1150mm usable width with thickness from 50mm to 100mm and rock wool density options from 80kg/m³ up to 140kg/m³, plus custom panel lengths on request.
Contractors rely on these panels for GMP pharma plants, electronics workshops, food factories and medical device lines. The interlocking tongue‑and‑groove design cuts air leakage, speeds installation, and keeps zones stable over years of operation, helping projects pass ISO and GMP audits more easily.

Deiiang MGO RockWool Panel Quality Control Flowchart
MGO RockWool Panels are custom-made for walls and ceilings inside cleanrooms.
We offer steel sheets of different thickness and materials as outer faces, with the core made of magnesium oxide mixed with rock wool to boost fire safety.
Rock wool works well to block noise and maintain stable temperature, and MGO can stop fire spread, as well as fend off water, damp and mold.
We produce all MGO rock wool cleanroom panels under standardized factory procedures rather than building walls on location.
Every panel is molded with precise tongue-and-groove connections in advance, so workers do not need extra cutting or trimming once the goods arrive.
You may put these panels together directly at your site. The finished wall surface stays smooth and nearly gap-free, leaving few spots where dust could build up.
MGO RockWool Panels bring many practical strengths when deployed in cleanrooms compared with standard panels.
These panels resist fire well and maintain steady indoor temperature while blocking excess noise. Their sleek surfaces are simple to wipe down, and closely fitted seams stop dust from gathering in gaps.
Our panels can be adjusted to meet both local and European criteria. They pass fire safety tests and satisfy the particulate control standards laid out in ISO 14644 and GMP.
The thickness and density are mainly determined based on the customer's sound and heat insulation needs, fire protection standards, and the intended use of the wall.
Standard cleanrooms use 50mm thick MGO RockWool Panels. For higher requirements in sound and heat insulation, 75mm–100mm thick boards can be selected. Standard cleanroom boards have a density of 70kg/m³. For higher requirements in wall structure and fire resistance, high-density boards (140kg/m³) can be selected.
In actual selection, the best suitable board material needs to be customized based on specific circumstances.
Yes, MGO RockWool Panels have excellent fire resistance. Both magnesium oxide and the rock wool core are non-combustible materials, resulting in a high overall fire rating for the composite board.
The panels produced by our factory are designed and tested according to GB and EN fire resistance standards and can be used for cleanroom walls and ceilings.
Magnesium oxide rock wool panels are ideal for clean corridors, aseptic storage areas, and evacuation routes because they comply with fire safety regulations and meet the requirements for cleanroom use.
Polyurethane and polystyrene foam boards are widely used in cold storage and simple workshops, but they are flammable. For many GMP-compliant cleanroom, pharmaceutical, and semiconductor projects, designers are now increasingly favoring non-combustible materials such as magnesium oxide rock wool panels.
Magnesium oxide rock wool panels for cleanrooms offer superior fire resistance, higher temperature stability, and better sound insulation. While the initial cost is typically slightly higher than polyurethane or polystyrene foam boards, the risk is lower, and long-term compliance is better.
If you are comparing quotes, in addition to board thickness and price, you should also check the core material, fire rating, and included cleanroom accessories of the magnesium oxide rock wool panel system.
Deiiang MGO RockWool Panels are widely used in pharmaceutical and biotechnology cleanrooms, medical device factories, hospital clean areas, electronics and semiconductor manufacturing plants, and food and cosmetic production.
In many industries, these panels are used not only for cleanroom walls but also for clean corridors, technical mezzanines, walkable ceilings, and fireproof equipment rooms around core clean areas.
When you send us your layout plan, we typically indicate which areas can use standard magnesium oxide rock wool panels and which areas require upgrades to magnesium oxide rock wool panels with higher fire resistance, greater density, or stainless steel.
Customers can fully customize Deiiang’s MGO rock wool panels for cleanrooms and match them with our supporting cleanroom doors and windows.
We adjust panel dimensions, thickness, joint forms and outer steel facings (either coated steel or 304 stainless steel) in factory production to fit door and window modules perfectly.
Our team arranges wall layouts and door window openings together at the design stage, so aluminum extrusions and seams line up neatly on site. For international projects, send us your URS and basic layout drawings, and our engineers will deliver a full solution with corner fittings and wall connection details.
The cleanroom panels you choose should match your process risks, regulatory expectations, and building conditions – not just price or a generic “cleanroom” label. Here is a concise checklist:
1. Industry, Process Risk & Regulatory Class
Map each room’s process (weighing, filling, packaging, assembly, testing) to its risk level and required ISO / GMP class so panel performance matches real audit needs.
High‑risk pharma and biotech areas usually need non‑combustible, low‑particle panels with documented fire and hygiene performance.
Electronics, semiconductor and battery lines may add ESD and particle control requirements on top of cleanability.
2. Fire Rating, Core Material & Safety Proof
Prioritize non‑combustible cores (MGO + rock wool) for zones with strict fire zoning, evacuation routes or large people/equipment loads.
Ask for third‑party fire test reports (e.g., Class A or equivalent) and clear declarations of core density, panel thickness and fire rating so your safety team and local authority can verify compliance.
3. Thermal, Acoustic & Moisture Performance
In temperature‑ or humidity‑controlled cleanrooms, panel thickness (50–100mm) and rock wool density must support your insulation targets to reduce HVAC energy use.
Where noise is critical (equipment rooms, labs beside offices), specify densities that improve sound insulation between clean and technical areas.
Review moisture resistance and dimensional stability data to avoid panel warping, gaps or mold growth in humid or wash‑down zones.
4. Surface Finish, Joints & Cleanability
Choose smooth, crack‑free, chemically resistant finishes that are compatible with your disinfectants and cleaning SOPs.
Check joint designs (enterprise splicing), sealants and corner details to prevent particle traps and air leaks, and to support easy wiping and visual inspection.
For higher ISO / GMP grades, prioritize panel systems with minimal exposed fixtures and validated cleanability to simplify qualification and routine audits.
