What are cleanroom walls made of?

Cleanroom walls are made of materials that are specifically designed to minimize particle generation, control static electricity, and resist chemicals. The choice of materials depends on the level of cleanliness required in the cleanroom and the specific industry standards that need to be met. Here are some common materials used for cleanroom walls:

1.Smooth, Non-Porous Surfaces: Cleanroom walls are typically smooth and non-porous to prevent the accumulation of dust and particles. Common materials include stainless steel, fiberglass-reinforced plastic (FRP), and epoxy-coated surfaces.

2.High-Pressure Laminates (HPL): HPL panels are made by impregnating multiple layers of kraft paper with phenolic resin and topping it with a decorative layer. These panels are durable, easy to clean, and resistant to chemicals, making them suitable for cleanroom walls.

3.Vinyl or PVC Panels: Vinyl or PVC panels are often used in cleanrooms because they are easy to clean, resistant to chemicals, and provide a smooth surface that discourages particle accumulation.

4.Aluminum or Steel Panels: Aluminum or steel panels with a baked enamel finish are used in some cleanroom applications. These panels are sturdy, resistant to corrosion, and can be easily cleaned to maintain cleanliness.

5.Acrylic or Glass: Cleanroom walls may incorporate acrylic or glass windows to allow visibility into the cleanroom. These materials are smooth and can be cleaned easily.

6.Seamless Wall Systems: Cleanroom walls are often designed with seamless construction to eliminate cracks and crevices where particles can accumulate. Seamless wall systems can be made from various materials, including fiberglass, stainless steel, or composite panels.

It’s important to note that cleanroom in Oman construction involves careful sealing and detailing to ensure that there are no gaps or openings where contaminants could enter. The choice of materials and construction methods depends on the specific requirements of the cleanroom environment, such as the level of cleanliness (measured in terms of ISO classes) and the industry standards that apply.
