When designing and constructing a cleanroom, selecting the appropriate wall system is crucial for maintaining hygiene and efficiency. Cleanroom wall panels not only provide structural support but also ensure adherence to stringent cleanliness and operational standards. Here, we delve into the various cleanroom wall system options available, highlighting their unique advantages.

Types of Modular Cleanroom Wall Panels

Insulated Metal Panels are one of the most commonly utilized materials in cleanroom design. These panels feature an insulating core encased in metal facings, delivering robust and durable walls suitable for partitions, external walls, and ceilings. Their impressive temperature control capabilities make them particularly effective for environments with specific thermal and humidity constraints.

Honeycomb Panels present a lightweight alternative without compromising on strength. Made with a honeycomb core of aluminum sandwiched between two metal skins, these panels boast an excellent strength-to-weight ratio, essential for cleanrooms with limited load-bearing capacities.

Liner Panels are an economical choice designed to modernize existing walls. Typically measuring ½ inch in thickness and made of steel or aluminum skins adhered to a honeycomb core, these panels are affixed to pre-existing structures to mimic the appearance and functionality of newly built walls.

Softwall vs. Rigid Wall Cleanrooms

Softwall cleanrooms utilize vinyl curtains and are ideal for areas that require moderate containment levels. These structures can also feature antistatic options to prevent electrostatic discharge.

On the other hand, rigid wall cleanrooms offer a variety of panel materials, including acrylic, static dissipative PVC, and polycarbonate, each with unique properties such as scratch and impact resistance tailored to meet specific cleanroom needs.

Drywall with Epoxy Coating or Cladding

For less stringent cleanroom areas, drywall coated with epoxy paint is an affordable alternative that provides substantial cleanliness and protection. This moisture-resistant coating results in a smooth and easily maintained surface. Hygienic cladding is another option that can be applied to drywall, ensuring a sealed finish through silicone caulking or heat sealing techniques.

Sealing Techniques for Cleanroom Panels

Panel seams are often secured using either silicone caulking or chemical cold welding. The latter method offers a continuous, smooth surface across the panel system, making it a preferred choice for stringent cleanroom environments. Meanwhile, silicone caulking allows for simpler installation and replacement of individual panels as required, providing more flexible options for future adjustments.

By carefully selecting and implementing the right cleanroom wall system, businesses can optimize their controlled environments for cleanliness and compliance with industry regulations.
