The difference between clean room and regular room

The difference between a cleanroom-grade sandwich panel room and a standard sandwich panel room lies primarily in the following aspects: 

1. Cleanliness

• Cleanroom-grade: Cleanrooms must maintain extremely high levels of cleanliness, minimizing the introduction of dust, particulates, and microorganisms. The cleanliness of cleanrooms is classified according to ISO 14644-1, ranging from Class 1 to 9, with Class 1 being the most stringent.

• Standard Room: Standard sandwich panel rooms do not adhere to specific cleanliness standards. They are primarily designed to protect against external environmental factors, with no special control over dust or particulates.

2. Materials and Finishing

• Cleanroom-grade: Cleanroom sandwich panels use specially treated materials to ensure smooth surfaces that are easy to clean and resistant to dust and microorganisms. Antimicrobial coatings may be applied, and joints are minimized to reduce potential contamination sources.

• Standard Room: Standard sandwich panels use relatively inexpensive materials, and surface finishing is not as critical. There is less focus on cleanability or preventing microbial adhesion.

3. Air Tightness

• Cleanroom-grade: Air tightness is crucial in cleanrooms to prevent the ingress of external air and contaminants. High-quality sealing and advanced airtight technologies are used in panel connections, doors, and windows.

• Standard Room: Standard sandwich panel rooms do not require the same level of air tightness as cleanrooms. Air infiltration and leakage are less of a concern, and sealing is less rigorous.

4. HVAC System

• Cleanroom-grade: Cleanrooms use specially designed HVAC (Heating, Ventilation, and Air Conditioning) systems to strictly control airflow, temperature, and humidity. HEPA filters are used to remove airborne particles, and positive or negative pressure is maintained to prevent contamination.

• Standard Room: The HVAC system in a standard sandwich panel room is relatively simple, focusing on basic temperature and humidity control rather than air cleanliness or pressure maintenance.

5. Usage

• Cleanroom-grade: Cleanrooms are used in industries requiring highly controlled environments, such as semiconductor manufacturing, pharmaceuticals, biotechnology, and medical device production.

• Standard Room: Standard sandwich panel rooms are used in warehouses, factories, and commercial buildings, where insulation and structural stability are more important than cleanliness.

Due to these differences, cleanroom sandwich panels are more complex to design and construct, typically resulting in higher costs compared to standard sandwich panels.
