Pannello sandwich per camere bianche in lana di roccia, realizzato a mano

Product Overview

The customized hand-made rockwool clean room sandwich wall panel is a non-combustible partition and ceiling panel engineered for controlled environments where fire safety, cleanability, and dimensional accuracy cannot be compromised. Each panel is built around a mineral rockwool core that is cut into strips, rotated so the fibers run perpendicular to the panel face, and hand-laid into a cold-rolled steel frame. This hand-made construction method — rather than continuous-line lamination — allows every panel to be produced to the exact width, length, thickness, and facing specification your clean room layout requires.

GloStar supplies these panels to pharmaceutical plants, hospitals, electronics fabs, food processing facilities, and laboratories that must satisfy ISO 14644 cleanliness classes and GMP requirements while also meeting strict national fire codes. Because the panel is fully customized, there are no wasted offcuts on site, no field-cut edges exposing raw rockwool, and no compromise between the drawing and what actually gets installed.

Why Choose a Hand-Made Rockwool Panel Instead of a Machine-Made Panel

Machine-made (continuous line) panels are efficient for large-volume, standard-profile production, but they lock you into fixed thicknesses, fixed facings, and fixed joint profiles. A hand-made rockwool clean room sandwich wall panel gives you flexibility that a production line cannot:

• Free choice of panel thickness, typically 50 mm, 75 mm, 100 mm, or 150 mm, without retooling.
• Mixed facing materials — for example, stainless steel on the clean side and pre-painted steel on the technical corridor side.
• Reinforced, fully enclosed edges with a steel or aluminum frame on all four sides, so no rockwool fiber is exposed at the joint.
• Panel lengths cut to the exact floor-to-ceiling dimension of your project, reducing horizontal joints that collect particles.
• Double tongue-and-groove or camlock joint profiles selected to suit the wall system, ceiling system, or return-air chase design.
• Custom cut-outs for view windows, pass boxes, doors, HEPA terminal boxes, sockets, and service penetrations, executed in the factory rather than on site.

Fire Performance and Core Material

Rockwool is the reason this panel is specified where PU, PIR, or EPS cores are not permitted. The basalt mineral core is inorganic and classified as A-grade non-combustible, with a melting point above 1000°C. It does not contribute fuel to a fire, does not drip, and generates negligible smoke and toxic gas.

• Fire classification: Class A / A1 non-combustible core in accordance with GB 8624; fire resistance integrity and insulation commonly tested to EI 60 and EI 90 depending on thickness and joint detail.
• Core density: 100–120 kg/m³ standard, with 80 kg/m³ and 140 kg/m³ available on request.
• Fiber orientation: vertical (perpendicular to the facing) for higher compressive and delamination resistance.
• Thermal conductivity: approximately 0.043 W/(m·K), supporting HVAC energy efficiency in conditioned clean spaces.
• Acoustic performance: sound reduction typically 28–36 dB depending on panel thickness and facing gauge, which is valuable in hospitals, laboratories, and equipment-adjacent clean corridors.

Rockwool is also hydrophobic-treated, moisture-resistant, dimensionally stable, and will not support mold, bacterial growth, or vermin — all direct requirements in GMP cleanroom design.

Facing Options and Surface Finishes

The clean room surface is where hygiene performance is actually delivered, so GloStar offers a full range of steel facings and coatings:

• Pre-painted galvanized steel (PPGI), 0.4–0.8 mm, with PE, HDP, or PVDF coating.
• Hot-dip galvanized steel for technical zones and chases.
• Stainless steel 304 or 316 for high-corrosion, washdown, or aseptic areas.
• Antibacterial coating options for pharmaceutical, biotech, hospital operating theatre, and food-grade applications.
• Standard clean room white and RAL 9003 / RAL 9010 finishes, with custom RAL colors available.
• Optional anti-static and chemical-resistant treatments for electronics and semiconductor environments.

All facings are flat, seamless, and non-shedding, with no ledges or open profiles that trap particles, making the wall surface fast to wipe down and compatible with routine disinfection protocols.

Technical Specifications

Specifications can be adjusted to match your project drawings, local code requirements, or existing panel system on site.

Typical Applications

• Pharmaceutical and biopharmaceutical production suites built to GMP standards
• Hospital operating theatres, ICUs, sterile supply departments, and laboratories
• Electronics, semiconductor, PCB, and optical assembly clean rooms
• Food and beverage processing, dairy plants, and cold-chain packing rooms
• Cosmetics, medical device, and diagnostic reagent manufacturing
• Research laboratories, animal facilities, and BSL-rated containment areas

In each of these environments, the panel is used for partition walls, ceiling systems, return-air chases, and machine-room enclosures, and it integrates with clean room doors, view windows, coved aluminum profiles, pass-through boxes, and FFU ceiling grids.

Clean Room System Compatibility

A wall panel only performs as well as the system around it. GloStar supplies the hand-made rockwool panel together with matching accessories so the finished envelope is airtight and cleanable: coved floor and ceiling profiles that eliminate 90-degree dust corners, aluminum alloy connecting profiles, sealed corner pieces, flush-mounted clean room doors, double-glazed flush view windows, and silicone sealing for every joint. This system approach helps projects achieve the required air-tightness for ISO Class 5 through Class 9 rooms and simplifies validation.

Customization and Ordering Process

1. Send your drawings, room layout, or bill of quantities, including required cleanliness class and fire rating.
2. Our engineering team confirms panel thickness, facing, joint type, module width, and accessory list.
3. You receive a detailed quotation with a shop drawing and panel schedule.
4. Panels are hand-produced to the confirmed cutting list, individually protected with PE film, and packaged for export.
5. Installation guidance, on-site technical support, and supervision are available for overseas projects.

Minimum order quantity, lead time, and export packing details are confirmed at quotation stage. OEM and ODM production is accepted.

Quality Assurance

GloStar operates its own hand-made clean roompanel production lines with in-house steel forming, rockwool cutting, and frame assembly. Panels are produced under ISO 9001 quality management, with raw material inspection, dimensional checks on every batch, and fire and thermal performance backed by third-party test reports. CE-compliant documentation and test certificates can be provided for export projects.

Domande frequenti

What is the difference between a hand-made rockwool panel and a machine-made rockwool panel?

Hand-made panels are assembled by inserting pre-cut rockwool strips into a steel frame, which allows fully customized dimensions, mixed facings, four-sided reinforced edges, and non-standard thicknesses. Machine-made panels are produced on a continuous line with fixed profiles and are better suited to large quantities of standard panels.

What fire rating does the rockwool clean room panel achieve?

The rockwool core is A-grade non-combustible. Depending on thickness, facing gauge, and joint detail, wall assemblies are commonly tested to EI 60 or EI 90 fire resistance. Test reports are available on request.

Can the panel size be fully customized?

Yes. Thickness, effective width, and length are made to your project drawings, and factory cut-outs for doors, windows, and service penetrations can be included in the panel schedule.

Is the panel suitable for GMP pharmaceutical clean rooms?

Yes. The flat, non-shedding, cleanable steel surface, sealed joints, coved profiles, and mold-resistant inorganic core meet the requirements of GMP and ISO 14644 clean room construction.

Which panel thickness should I choose?

50 mm is common for internal partitions in general clean rooms, 75 mm and 100 mm are used where higher fire resistance, thermal insulation, or wall height requires added rigidity, and 150 mm is selected for cold-side or fire-compartment walls. Our engineers can recommend a thickness based on your wall height and code requirements.

Do you supply clean room accessories as well as panels?

Yes. Doors, view windows, aluminum profiles, coving, and sealing systems are supplied as a complete package so the clean room envelope is installed as one coordinated system.
