Modular Cleanroom Wall Panels: Types, Materials, and Applications

Created on 01.28
Modular cleanroom wall panels are a critical component of modular cleanroom systems, directly affecting cleanliness performance, structural stability, flexibility, and long-term operation. Compared with traditional masonry walls, modular cleanroom wall panels offer faster installation, better sealing performance, and greater adaptability to different cleanroom applications.
This article introduces the main types of modular cleanroom wall panels, common materials, and their typical applications across industries.

What Are Modular Cleanroom Wall Panels?

Modular cleanroom wall panels are prefabricated wall systems designed specifically for cleanroom environments. They are manufactured in standardized modules and assembled on-site using aluminum or stainless-steel framing systems.
These panels are engineered to:
Maintain controlled airflow and pressure
Minimize particle generation
Support fast installation and future reconfiguration
Integrate seamlessly with cleanroom ceilings, doors, and windows
Modular wall panels are widely used in ISO 5 to ISO 8 cleanrooms for laboratories, pharmaceutical facilities, electronics manufacturing, and medical environments.

Types of Modular Cleanroom Wall Panels

Different cleanroom applications require different wall panel configurations. The most common types include:

Softwall Cleanroom Panels

Softwall panels use flexible materials such as anti-static PVC curtains, suspended from a lightweight frame.
Key Features:
Cost-effective and fast to install
Ideal for temporary or flexible cleanroom spaces
Commonly used in FFU cleanroom systems
Typical ISO Class: ISO 6–ISO 8Applications: R&D labs, electronics assembly, temporary clean areas

Hardwall Cleanroom Panels

Hardwall cleanroom panels are rigid wall systems designed for long-term and regulated environments.
Key Features:
Strong structural stability
Better airtightness and pressure control
Suitable for GMP-compliant cleanrooms
Typical ISO Class: ISO 5–ISO 7Applications: Pharmaceutical cleanrooms, medical laboratories, hospital clean areas

Common Materials Used for Cleanroom Wall Panels

Tempered Glass Panels

Smooth, non-porous surface
Excellent visibility and aesthetics
Easy to clean and disinfect
Common Uses: Laboratories, hospital cleanrooms, inspection areas

Acrylic (PMMA) Panels

Lightweight and impact-resistant
Good transparency at a lower cost than glass
Suitable for modular and semi-permanent cleanrooms
Common Uses: Electronics cleanrooms, clean booths, R&D spaces

Sandwich Panels

Sandwich panels consist of a core material (PU, PIR, or rock wool) bonded between two metal sheets.
Advantages:
Thermal insulation
Sound reduction
Fire-resistant options available
Common Uses: Pharmaceutical and biopharma cleanrooms, industrial cleanrooms

Anti-static PVC Curtains

Flexible and lightweight
Anti-static treatment reduces particle attraction
Easy to replace and relocate
Common Uses: Softwall modular cleanrooms, FFU cleanroom enclosures

Key Performance Considerations for Cleanroom Wall Panels

When selecting modular cleanroom wall panels, several technical factors should be considered:
Airtightness: Prevents contamination and supports pressure control
Surface Smoothness: Reduces particle accumulation
Chemical Resistance: Withstands cleaning agents and disinfectants
Fire Resistance: Required in pharmaceutical and hospital projects
Compatibility: Seamless integration with ceilings, HVAC, and FFU systems
Proper wall panel selection directly impacts cleanroom performance and compliance with ISO 14644 and GMP standards.
