What are the different types of clean room walls?
Created on 07.28
Clean rooms are critical in industries like pharmaceuticals, electronics manufacturing, biotechnology, and aerospace, where contamination control is essential. One of the most important components of a clean room is its walls, which must meet strict standards for durability, cleanliness, and airflow control.
In this blog, we’ll explore the different types of clean room walls, their materials, and their applications to help you choose the best option for your facility.
1. Modular Clean Room Wall Panels
Modular panels are the most common type of clean room walls due to their flexibility, ease of installation, and reconfigurability.
Types of Modular Wall Panels:
Sandwich Panels – Made with an insulating core (often polystyrene, polyurethane, or mineral wool) sandwiched between two metal or composite sheets.
Solid Aluminum Panels – Non-porous, durable, and easy to clean, ideal for high-cleanliness environments.
Stainless Steel Panels – Used in ultra-clean environments like semiconductor manufacturing and medical labs due to their corrosion resistance.
FRP (Fiberglass Reinforced Plastic) Panels – Lightweight, chemical-resistant, and non-shedding, making them suitable for pharmaceutical and food processing clean rooms.
Best for: Laboratories, medical device manufacturing, semiconductor facilities.
2. Hardwall Clean Rooms
Hardwall clean rooms are permanent structures built with rigid materials, offering superior durability and airtight sealing.
Common Materials:
Gypsum Board with Epoxy Coating – Cost-effective and smooth for easy cleaning.
Painted Steel or Aluminum – Used in environments requiring high structural integrity.
Glass Partitions – Provide visibility while maintaining cleanliness (often used in ISO Class 5-8 clean rooms).
Best for: Pharmaceutical production, aerospace, and long-term clean room installations.
3. Softwall Clean Rooms
Softwall clean rooms use flexible, lightweight materials like vinyl or PVC curtains, making them easy to assemble and relocate.
Features:
Transparent Vinyl Curtains – Allow visibility while maintaining contamination control.
Zippered Entryways – Help maintain air pressure differentials.
Portable & Cost-Effective – Ideal for temporary or small-scale clean room needs.
Best for: Small-scale manufacturing, research labs, temporary clean spaces.
4. Hybrid Clean Room Walls
Some clean rooms combine different wall types to optimize performance. For example:
Lower sections made of stainless steel (for durability and chemical resistance).
Upper sections with glass or acrylic (for visibility and natural light).
Best for: Custom clean room setups where flexibility and specific material properties are needed.
Key Factors in Choosing Clean Room Walls
When selecting clean room walls, consider:✔ Cleanliness Class (ISO Standard) – Higher-class clean rooms need smoother, non-porous materials.✔ Chemical & Corrosion Resistance – Important for labs handling solvents or acids.✔ Ease of Cleaning & Maintenance – Smooth, seamless surfaces reduce particle accumulation.✔ Modularity & Future Expansion – Industries with evolving needs benefit from reconfigurable walls.
Final Thoughts
The right clean room wall system depends on your industry, cleanliness requirements, and budget. Modular panels offer flexibility, hardwall structures provide permanence, and softwall solutions are great for temporary setups.
