The cleanroom

Both architectural and building services aspects are very important when designing a cleanroom.


Due to the need to capture airborne particulate matter and microorganisms, special attention must be paid to the architectural wall finish of a cleanroom. Through years of experience in building cleanrooms, Interflow has developed its own modular prefabricated wall system of high pressure laminate (HPL) that meets required guidelines: CleanWall. The unique concept of CleanWall is reflected in its components. CleanWall has been developed and constructed in such a way that the integrated return channels, smooth wall finish and fully integrated window and door frames all contribute to a wall system that can be optimally used in Interflow's cleanroom concept.


In addition to a smooth wall and ceiling finish, the floor used in a cleanroom plays an important role in the ‘finishes’ of the room and can have a positive impact on to the particle-free degree. The floor in the cleanroom should also be easy to clean, therefore Interflow uses a sanitary plinth finish. Depending on the application and your requirements, there are different types of floor finish available. Floor systems used can be both antistatic and conductive.


Depending on the classification and application, Interflow offers a ceiling system that meets the required guidelines: CleanCeiling

Advantages of CleanCeiling:

  • Modular ceiling system with a grid size of 1,200 x 2,400 mm and completely removable.
  • Walkable as standard (for service/ maintenance purposes).
  • Suitable for installing Fan Filter modules of 590 x 1,190 mm.
  • Easy to integrate air supply elements and lighting fixtures.
  • Hermetically sealed.
  • The ceiling system is prefabricated so that no machining and dust-producing operations take place on the construction site.
  • Fast installation time on site.

Interflow CleanWall and CleanCeiling
