Glostar Hollow Glass-Magnesium Clean Room Panel — Wall & Ceiling Application
Product Overview
What Is a Hollow Glass-Magnesium Clean Room Panel?
Glostar hollow glass-magnesium clean room panels are a precision-engineered sandwich panel system designed specifically for controlled environments. Each panel features a pre-painted galvanized steel outer facing, a structural hollow glass-magnesium (MgO) core grid, a galvanized steel internal keel frame, and an inner steel facing — bonded together under heat and pressure using a thermosetting adhesive.
The MgO core is produced from magnesium oxide, magnesium chloride, and water, reinforced with medium-alkali glass fiber mesh and filled with lightweight aggregate. This combination delivers Class A1 non-combustible performance, outstanding moisture resistance (hydrophobicity ≥ 97.5%), zero formaldehyde or benzene emissions, and a high-rigidity hollow structure that provides both sound insulation (≥ 44 dB) and thermal stability — making it the cleanroom panel of choice for pharmaceutical GMP facilities, ISO-classified electronics labs, hospital operating theatres, and food processing plants worldwide.
Key Advantages
7 Reasons Cleanroom Engineers Specify Glostar MgO Panels
01 · FIRE SAFETY Class A1 Non-CombustibleMagnesium oxide is inherently non-combustible, achieving the highest possible fire classification — Class A1 per EN 13501-1. Fire resistance exceeds 70 minutes. The core releases no toxic smoke or harmful gases when exposed to high temperatures, protecting building occupants and sensitive processes alike. |
02 · SOUND INSULATION ≥44 dB Acoustic PerformanceThe regular hollow-grid structure of the MgO core creates a highly effective acoustic barrier. At ≥ 44 dB sound reduction, Glostar panels are widely used to isolate mechanical equipment rooms, grinding rooms, and vibration-sensitive laboratory spaces from adjacent production or office areas. |
03 · MOISTURE RESISTANCE ≥97.5% HydrophobicityThe MgO board core achieves ≥ 97.5% hydrophobicity — resisting moisture absorption, warping, swelling, and mold growth even in high-humidity production environments such as beverage plants, food processing areas, and tropical-climate facilities. |
04 · HYGIENE & CLEANABILITY Zero Toxic EmissionsPanels contain no asbestos, formaldehyde, or benzene. The smooth pre-painted steel surface is non-porous, easy to wipe down with disinfectant, and resistant to microbial adhesion — essential for pharmaceutical GMP compliance and food-grade hygienic zoning. |
05 · STRUCTURAL STRENGTH Lightweight Yet LoadbearingDespite its hollow-core lightweight design, the reinforced MgO grid delivers high compressive and flexural strength. Ceiling panels are walkable and support a live load of approximately 150 kg/m² — equivalent to 2 persons per square meter — making maintenance access safe and straightforward. |
06 · AIRTIGHT JOINTS Contamination-Free SealingThe tongue-and-groove joint system creates a continuous airtight seal between panels, eliminating particle-trapping gaps and preventing cross-contamination between cleanroom zones. Compatible with concealed "+" aluminum profile ceiling hanger systems for seamless clean-room aesthetics. |
07 · INSTALLATION SPEED
Modular Design — Fast On-Site Assembly
Panels ship in pre-cut, factory-dimensioned modules. The interlocking pull-and-fit joint system requires no specialist tools — wall panels can be installed vertically or horizontally, and ceiling panels suspended from concealed "+" aluminum profiles at 1m hanger spacing. Pre-wired conduit channels can be embedded in panels during factory production, eliminating secondary penetration work on site and reducing the risk of particle generation in operational facilities.

Production Types
Handmade vs. Machine-Made: Which Should You Specify?
HANDMADE · Premium Finish
Hand-Pressed Production LineEach panel is hand-assembled with the galvanized steel keel, MgO core, and steel facings, then hot-pressed and adhesive-cured. The handmade process produces a flatter surface finish and higher dimensional accuracy than standard machine-made — making it the preferred choice for pharmaceutical GMP facilities and hospital operating theatres where surface planarity is critical.
|
MACHINE-MADE · High Output
Continuous Production LinePanels are produced on an automated continuous foaming and pressing line for high-volume output with consistent dimensional tolerances. Machine-made panels offer excellent value for large-scale industrial cleanroom, food processing, and logistics facility projects where production speed and cost efficiency are prioritized alongside quality.

FAQ
Frequently Asked Questions
What is the difference between hollow glass-magnesium panels and rock wool cleanroom panels?
Both achieve Class A fire ratings, but they serve different priorities. Rock wool panels offer superior thermal and acoustic insulation (STC 45–55 dB) and are preferred for high fire-risk environments such as chemical plants and data centers. Hollow glass-magnesium panels are lighter, easier to cut and install, offer excellent moisture resistance (≥ 97.5% hydrophobicity), and produce a harder, more impact-resistant interior surface — making them the dominant choice for pharmaceutical, hospital, and food-processing cleanrooms globally.
Can hollow glass-magnesium panels be used as cleanroom ceiling panels?
Yes — and it is one of their most common applications. Ceiling panels are suspended from concealed "+" aluminum profiles with hanger fittings at 1m centers. The panels are walkable and support approximately 150 kg/m² (≈ 2 persons/m²). A minimum plenum height of 1.2m above the ceiling is recommended to allow for HEPA filter, air duct, and lighting installation. Maximum recommended ceiling span is 3m.
Are these panels compliant with GMP pharmaceutical standards?
Yes. Glostar hollow glass-magnesium panels meet GMP cleanroom construction requirements: Class A1 non-combustible core, smooth pre-painted steel surfaces that are non-porous and chemical-disinfectant resistant, zero formaldehyde / benzene emissions, and airtight tongue-and-groove joints that prevent particle accumulation. For pharmaceutical clients, we recommend the handmade production variant for superior surface flatness, and can supply matching GMP-grade cleanroom doors and windows from the same product system.
Can openings be cut into panels for lights, HEPA filters, and air conditioning units?
Yes. Openings can be made on site to accommodate HEPA filters, LED ceiling lights, air conditioning diffusers, and pass-through ports. For pharmaceutical and electronics projects, conduit channels and junction boxes can be factory-embedded into panels during production, eliminating the need for secondary penetration work on site and reducing contamination risk during construction.
What is the minimum order quantity and how long does production take?
MOQ is 500 m². Standard production lead time is 15–25 days after deposit, depending on thickness and customization. Size, color, coating type, and surface material (color steel or stainless steel) can all be customized without significant impact on lead time for most orders.
