Material Selection and Application in Cleanroom Construction

The choice of materials used in the construction of a Cleanroom has a direct impact on the cleanliness, durability and operational efficiency of the final environment. Whether used in the pharmaceutical, electronics manufacturing or biotechnology industries, the right materials will not only meet ISO Cleanroom standards, but also reduce long-term maintenance costs.

Why material selection is so critical?

Cleanrooms, especially ISO Cleanrooms that comply with ISO standards, have extremely stringent requirements for the cleanliness of their environments. Imagine a Cleanroom in an industry such as pharmaceuticals or electronic chip manufacturing, where even the tiniest particle of dust can cause serious problems. For example, in the pharmaceutical process, impurities may affect the quality and safety of drugs. In chip manufacturing, a particle of dust may lead to chip short-circuit scrap. The right material is the first line of defense for the Cleanroom environment. It should not only be able to reduce its own particles, but also have a good ability to resist contamination, so as to ensure that the cleanroom is always in a highly clean state, in line with the strict ISO Cleanroom standards.

Key materials and their applications

1. Wall and partition materials

In Clean Room Design, the following materials are usually used for walls:

• Color Steel Sheet (Sandwich Panel): Lightweight, fire resistant, easy to clean and suitable for most ISO Class 1-8 Cleanrooms.

• Stainless Steel Panels: Corrosion resistant and suitable for environments with high humidity or where frequent sterilization is required (e.g. pharmaceutical industry).

• Glass Wall: Provides good visibility while meeting sealing requirements, commonly used in laboratories or observation areas.

2. Floor Materials

Cleanroom floors must be anti-static, hard-wearing and seamless to minimize the risk of dust accumulation. Common choices include:

• Epoxy resin flooring: Seamless, chemical resistant and suitable for electronics manufacturing.

• PVC flooring: Superior anti-static properties, easy to clean, suitable for the pharmaceutical industry.

• Raised flooring: facilitates cabling while maintaining airflow organization, commonly used in high-level ISO Cleanrooms.

3. Cleanroom Ceiling system

• High efficiency filter (HEPA/ULPA) integrated ceiling: To ensure air filtration efficiency.

• Metal ceiling: Used with FFU (Fan Filtration Unit) to optimize airflow distribution.

4. Doors, windows and sealing materials

Cleanroom doors and windows must ensure airtightness, common designs include:

• Automatic door closers: Reduce the risk of contamination when people enter and exit.

• Double-glazed windows: Improve thermal and acoustic insulation while preventing condensation.

• Silicone seals: Ensure that there are no leaks at the seams and maintain a positive pressure environment.

Summary

When building a Cleanroom, the choice of each material is critical to the performance and operation of the entire cleanroom. From walls and ceilings to floors, doors and windows, every detail needs to be carefully considered. Only by choosing the right materials and installing and applying them according to strict standards can we create a quality cleanroom that meets ISO Cleanroom standards.
