latest company case about Guangzhou Cleanroom Construction Co., Ltd. Certifications

Cleanroom construction plays a critical role in industries such as pharmaceuticals, biotechnology, semiconductors, and aerospace. A cleanroom is a controlled environment designed to minimize airborne particles, microbial contamination, and other pollutants. Choosing the right construction method ensures compliance with international standards, long-term efficiency, and safety.

In this blog, we will explore different types of cleanroom construction, compare their advantages, and help you select the best solution for your facility.

Conventional cleanroom construction uses materials like drywall, gypsum board, or brick walls. This method is highly customizable and offers strong structural stability.

Advantages:

• Flexible layouts for complex projects
• Solid and permanent structure
• Meets high regulatory requirements

Disadvantages:

• Long construction time
• Higher risk of contamination during building
• Cost-intensive compared to modular systems

Best for: Large-scale, long-term facilities with specific layout needs.

Modular cleanrooms are built using prefabricated wall panels, aluminum framing, and integrated systems. This method allows for fast installation, scalability, and easier maintenance.

Types of Modular Cleanrooms:

• Hardwall Modular Cleanrooms: Durable, rigid panels that provide excellent contamination control and can be easily expanded.
• Softwall Cleanrooms: Flexible PVC or vinyl curtains that allow cost-effective, rapid deployment for less critical applications.
• Hybrid Modular Solutions: Combining hardwall and softwall elements for both performance and flexibility.

Advantages:

• Short construction time
• Easy to expand, relocate, or upgrade
• Cleaner installation with minimal disruption
• Cost-effective in long-term operations

Best for: Pharmaceutical labs, biotechnology research, electronics, and industries requiring frequent modifications.

For facilities that already exist, cladding involves applying FRP, PVC, or aluminum composite panels to existing walls. This method is often used in renovation projects to upgrade an area to cleanroom standards.

Advantages:

• Lower cost than full rebuild
• Quick installation
• Ideal for upgrading existing facilities

Best for: Facilities needing ISO upgrades or partial cleanroom areas without full reconstruction.

When planning a cleanroom, consider:

• Cleanroom Classification: ISO 1–9 or GMP requirements.
• Industry Standards: cGMP, FDA, EU GMP, ISO standards.
• Scalability: Future expansions or reconfigurations.
• Budget & Timeline: Short-term vs long-term investment.
• Energy Efficiency & Maintenance: HVAC, airflow, and filtration costs.

With industries requiring faster deployment and flexible layouts, modular cleanrooms have become the preferred choice worldwide. They allow businesses to adapt quickly to new regulations, technologies, and market demands, while reducing downtime and operational costs.

Cleanroom construction is not a one-size-fits-all solution. From traditional builds to modular systems and retrofit upgrades, each method has its unique advantages. By carefully assessing your industry requirements, compliance needs, and long-term goals, you can select the most effective cleanroom construction approac.
