What To Consider When Choosing Walls For Your Cleanroom

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. They need to keep out airborne particles that may cause contamination and be designed to allow you to control temperature, humidity and air flow.

As cleanrooms can be used for a range of functions, from specialist manufacturing to medical and pharmaceutical or even the aerospace industry it’s also important to consider how your cleanroom will be used once it is installed.

In the past, traditional materials were used and then a coating, either made from PVC or epoxy paint was used. Composite panels are now a better alternative to this. Installing a cleanroom using composite wall panels can be more cost-effective, much quicker to install, produce less waste during installation and they are designed to have a lower permeability to water and air.

When deciding which panels are right for your cleanroom, you need to consider both the core and the panel finish.

Panel Core

The panel core will depend on your requirements:

  • The Puracore® Flush Cleanroom Aluminium Honeycomb system is suitable for any classification of cleanroom. The core is non-shedding, non-combustible and the system is certified to the highest Factory Mutual (FM) classification.
  • IPN-QuadCore is the first closed cell insulated panel core to be certified to FM 4882 for use in smoke sensitive occupancies, so is ideal for use in cleanroom environments.
  • Polyisocyanurate (PIR) is resistant to moisture ingress, preventing the growth of mould and fungi, and are free of harmful chemicals (CFC).
  • Mineral Fibre cored panels are an ideal choice for hygienic storage areas and where fire ratings are important. 

Panel Finish

Selecting the right panel finish for your cleanroom depends on a number of factors, including the humidity, cleaning process and application. If you are unsure about the options that would suit your cleanroom, then it’s best to speak to an expert.

The panel finish options are:

White Foodsafe Laminate
