How to Choose the Right Cleanroom Materials
Selecting the right cleanroom materials is a critical step in ensuring the efficiency, safety, and reliability of your controlled environment. The choice of materials impacts contamination control, maintenance, durability, and overall compliance with ISO cleanroom standards. In this article, we provide practical guidance to help facility managers, engineers, and designers make informed decisions. Farclean offers expertise in cleanroom materials suitable for diverse industrial applications.
1. Understand Your Cleanroom Requirements
Before selecting materials, clearly define:
- The ISO cleanliness class required (ISO 5–ISO 8)
- Temperature and humidity control needs
- Chemical exposure in cleaning or production processes
- Mechanical stress or traffic in the space
These parameters will directly influence which wall panels, flooring, ceilings, doors, and windows are appropriate for your cleanroom.
2. Material Performance Considerations
Cleanliness and Particle Control
Materials must minimize particle shedding and be easy to clean. Options like non-porous wall panels, epoxy flooring, and stainless steel surfaces help maintain consistent ISO compliance.
Chemical Resistance
Disinfectants and solvents are widely used in cleanrooms. Materials must withstand substances such as IPA, hydrogen peroxide, and sodium hypochlorite without degradation.
Temperature and Humidity Stability
Some cleanrooms, including battery dry rooms or pharmaceutical production areas, require materials that resist expansion or contraction under temperature fluctuations or high humidity.
Mechanical Strength
Floors, walls, and doors should resist impacts, scratches, and operational wear to ensure long-term durability and reduce maintenance costs.
Fire Safety
Compliant materials with fire ratings (FM, UL, or EN standards) provide safety and meet regulatory requirements.
3. Common Cleanroom Materials
Wall and Ceiling Panels
- PU/PIR sandwich panels – lightweight, thermally stable
- Rockwool panels – fire-resistant, commonly used in pharmaceutical and electronics industries
- HPL panels – scratch-resistant, easy to sanitize
- Stainless steel panels – ideal for chemical-heavy environments
Flooring
- Epoxy – seamless, chemical-resistant, easy to clean
- PVC – economical, suitable for medium-class cleanrooms
- Anti-static – required for semiconductor and electronics applications
Doors and Windows
- Flush aluminum or steel doors
- Double-glazed windows for clean zones
- Hermetic sliding doors for sterile or critical zones
4. Industry-Specific Material Selection
- Electronics & Semiconductor: ISO 5–7, anti-static finishes, low VOC coatings
- Pharmaceutical & Biotech: GMP-compliant surfaces, antimicrobial coatings, disinfectant resistance
- Food & Beverage: Hygienic, corrosion-resistant, easy-clean materials
- Lithium Battery Manufacturing: Moisture-resistant cores, airtight joints, temperature/humidity-tolerant finishes
