Current GMP regulations and other applicable specifications clearly define how a cleanroom must be designed. In practice, client needs must also be considered when selecting the most appropriate solution during on-site implementation. Ronny Töpfer, Project Engineer at Glatt Ingenieurtechnik (Weimar, Germany) explains how to successfully install cleanroom ceilings.

What applies to the design of doors, glazing and walls in cleanrooms also plays a major role when it comes to ceilings: all planning issues must be carefully assessed and clarified with the customer before either a conversion or new construction project begins. As part of the process, issues relating to false ceiling installations, such as the lighting and air outlets, should be agreed at an early stage. It's crucial that every aspect is closely integrated into the planning process. Glatt Ingenieurtechnik, for example, relies on its own in-house specialists for elements such as HVAC, EI&C, black and clean media, etc. This means that everything can be co-ordinated with maximum efficiency. If external service providers are involved, they should be integrated as closely as possible into the project structure.

Ceiling Systems And Their Areas of Application

With cleanroom ceiling systems, there are three main categories: supporting grid, clamping cassette and panelled versions. They are generally used in cleanrooms of Class ISO 8 and similar. For lower-rated cleanroom areas, the use of a drywall scheme and compatible coatings is acceptable. As with the wall systems, tightness of fit must be ensured by minimising the number of joints.
