When designing and planning a controlled environment such as a cleanroom, one of the most important things to think about is what materials you need for your cleanroom walls. It’s important to keep out airborne particles that may cause contamination and allow for an integrated design for control of temperature, humidity and air flow.
Each cleanroom and its application will be very unique, where containment laboratories within microbiology research will have different control requirements to that of R&D facilities within the aerospace industry. Therefore, the make-up of your cleanroom is vital in ensuring that it can be used for its intended purpose. Let’s consider the following aspects:
The use of the room – is it a lab, cleanroom or a containment laboratory?
Room classification – ISO 4-9, EU GMP A-D or CL2/CL3
Specification – does the facility require fire-rated, temperature-control or humidity control properties?
Once the factors above have been decided, the most suitable panel core and finish can be chosen.
In the past, traditional insulated materials followed by a PVC coating or Epoxy paint were used to achieve a suitable cleanroom finish. However, composite panels are now a better alternative to this, thanks to their cost efficiency, rapid install time, lower permeability to water and air and less waste produced during each build.
Panel Core
The panel core will depend on your requirements:
Selecting the right panel finish for your cleanroom depends on a number of factors, including the specification, cleaning process and application:
White Foodsafe Laminate
Commonly used in cleanroom environments as harsh chemicals are present, it’s easy to clean and mould resistant.
PET
PET is a robust panel finish that is suitable for environments dealing with the harshest chemicals and detergents.
Stainless Steel
Stainless Steel is a great choice for environments that contain a high moisture level.
Depending on the application, an appropriate choice of sealant should also be considered – silicone sealant, non-silicone-based sealant or vinyl welding.
Ancillaries
Once the requirements of your cleanroom have been considered and a panel core and finish have been chosen, additional details such as doors and vision panels should also be implemented into the design. Cleanroom ancillary options are available to ensure a fully flush or semi-flush specification.
