Clean room wall panels combine polyurethane (PU) or polyisocyanurate (PIR) insulation cores with corrosion-resistant stainless steel or pre-painted galvanized steel cladding. The CFC-free foam cores deliver high thermal resistance while meeting international hygiene standards including EC and USDA requirements for food-safe environments. Panel construction resists moisture, chemicals, and bacterial growth for controlled environments demanding strict cleanliness.
Tongue and groove edge joints interlock seamlessly with adjacent panels, supplemented by integrated cam-lock mechanisms that create airtight seals. This design eliminates thermal bridging and prevents air infiltration, maintaining consistent temperatures while maximizing energy efficiency. The high-density foam core (40-45 kg/m³) provides compressive strength and impact resistance with low thermal conductivity.
The modular cam-lock system enables rapid installation without on-site cutting, supporting both vertical and horizontal orientations as well as direct mounting of process equipment. Thicknesses, surface profiles, and RAL colors are configurable to match the room classification.
Applications include pharmaceutical facilities, food processing plants, laboratories, and electronics manufacturing clean rooms where stringent temperature control and hygiene are essential for environmental protection and product preservation.
Global Supplier of Custom Clean Room Wall Panels
In a cleanroom, the wall system is the first line of defense against contamination. RaxPanel manufactures wall panels that help pharmaceutical, biotechnology, and electronics facilities meet ISO 14644 and GMP particle limits without sacrificing speed of assembly.
The defining feature of our cleanroom wall panels is the fully flush surface. Double-male-female aluminum profiles interlock with zero step between adjacent panels, leaving no ledges, gaps, or exposed fasteners where dust and microbes can collect. Smooth, non-porous steel or stainless steel faces — finished with anti-bacterial and optional anti-static (ESD) coatings — shed no particles and withstand repeated wipe-down with biocides and vaporized hydrogen peroxide.
We build wall systems for every classification, from general ISO 8 utility rooms to ISO 5 sterile filling suites and semiconductor fabs. Radius corner covings, flush-mount door and window frames, and concealed gasketing complete an enclosure that is straightforward to validate and to clean. Share your room classification, dimensions, and surface specification, and we will configure a wall system to suit it.

ISO 14644 & GMP Clean Room Panel System Guide
Cleanroom sandwich panels are specifically engineered for contamination-controlled environments in pharmaceutical manufacturing, semiconductor fabrication, biotechnology labs, and medical operating suites. Built with anti-static, anti-bacterial coated steel facings or Grade 304 stainless steel bonded to Rockwool or Aluminum Honeycomb cores, these panels comply with ISO 14644-4 Class 1 to Class 9 and EU GMP Annex 1 sterility mandates.
💡 Pro Tip: Flush Joint Aluminum Profiles & VHP Resistance
At RaxPanel, our cleanroom panels feature double-male-female aluminum keels that interlock completely flush with 0mm surface steps. Joints are sealed with medical-grade non-outgassing silicone, eliminating ledges where dust or microbes collect and standing up to daily Vaporized Hydrogen Peroxide (VHP) sterilization.

1. Why Are Anti-Static (ESD) and Anti-Bacterial Coatings Required?
Standard building steel paint attracts airborne dust through static charge. RaxPanel cleanroom coatings maintain surface resistivity of 10⁶ to 10⁹ Ω/sq to prevent Electrostatic Discharge (ESD) damage in microelectronics, while nano-copper/silver ion additives inhibit bacterial growth by > 99.9%.
2. What Core Options Fit Cleanroom Walls vs Walk-On Ceilings?
Cleanroom core selection governs structural deflection under differential air pressure (+50 Pa) and foot-traffic maintenance loads:
3. How Integrated Cleanroom Doors and Double-Glazed Windows Maintain Air Pressure
RaxPanel cleanroom doors install completely flush with adjacent wall panels on both sides. Windows feature double-glazed toughened safety glass filled with dry nitrogen gas and internal desiccant to prevent condensation fogging.
4. Chemical Washdown Immunity (VHP & 70% IPA)
🧪 Sterilization Chemical Resistance:
- Vaporized Hydrogen Peroxide (VHP): Special HDP/PVDF paint coatings withstand 35% concentration VHP decontamination cycles without surface blistering.
- Alcohol & Disinfectant Wipes: Resistant to continuous wiping with 70% Isopropyl Alcohol (IPA), sodium hypochlorite, and quaternary ammonium biocides.
5. Where Are Cleanroom Panel Systems Most Commonly Installed?
💊 Pharmaceutical Facilities & Sterile Filling Rooms
EU GMP Grade A/B/C/D compliant aseptic processing and packaging suites.
🔬 Semiconductor & Optoelectronics Fabs
ISO 5 / Class 100 anti-static ESD safe wafer fabrication and laser labs.
6. Aluminum Radius Coving for 90° Wall-to-Floor Junctions
To comply with GMP sanitation, all 90° internal wall-to-wall and wall-to-floor corners are fitted with clip-in concave aluminum coving profiles (R50mm), ensuring rounded, easy-to-wipe corner transitions.
Frequently Asked Questions (FAQS)
1. What ISO cleanroom classifications do RaxPanel cleanroom panels satisfy?
Our cleanroom panel systems comply with ISO 14644-4 Class 1 through Class 9 specifications, as well as EU GMP Annex 1 Grade A, B, C, and D aseptic manufacturing standards.
2. Why is a flush-joint system mandatory for pharmaceutical cleanrooms?
Flush joints eliminate steps, gaps, and exposed screw heads where dust, bacteria, or spores can hide, allowing thorough wiping and biocide disinfection.
3. What core material is recommended for walk-on cleanroom ceiling systems?
Aluminum Honeycomb core is recommended for walk-on ceilings due to its high stiffness-to-weight ratio, structural flatness, and support for HVAC maintenance personnel.
4. Are RaxPanel cleanroom coatings resistant to Vaporized Hydrogen Peroxide (VHP)?
Yes. Our specialized PVDF and HDP cleanroom steel coatings withstand continuous 35% VHP vapor decontamination cycles without paint peeling or discoloration.
5. How do anti-static ESD cleanroom panels work?
ESD coatings maintain a surface resistivity of 10⁶ to 10⁹ Ω/sq, safely bleeding off static charges to ground and preventing micro-particle static attraction.
6. Are cleanroom doors and windows pre-engineered to fit the panel thickness?
Yes. RaxPanel cleanroom doors and double-glazed nitrogen-filled windows are manufactured to match the exact panel thickness (50mm / 75mm / 100mm) for double-sided flush installation.
7. What aluminum profile accessories are supplied with cleanroom panel packages?
Packages include aluminum floor channels, internal concave corner covings, external 3-way corner caps, ceiling suspension T-bars, and medical silicone sealants.
