​Ceilings for Clean Rooms

Control contamination in clean rooms by maintaining control over the environment

​Clean Room ceilings help control contamination and maintain performance standards in clean room applications.

Control contamination in clean rooms by maintaining control over the environment. Washable, scrubbable and soil resistant clean room ceiling tiles are engineered to achieve performance goals for food processing areas, laboratory, data center, electronics, and clean room assemblies. These ceiling tiles offer a high level of performance, including no sag performance, durability, and fire resistance. Used with Clean Room grid, they create a reliable system to help control contamination.

What is a clean room?

A clean room is an enclosed space employing environmental control over atmospheric contamination, temperature, humidity, and pressure. The cleanliness of the space is defined by ISO Standard 14644-1, which replaced Federal Standard 209E.

This standard (ISO 14644-1) is a document defining the number and size of the particles in a clean room environment. The specification looks at a clean room as a total system. It does not classify the individual components that make up the clean room.

How are cleanliness levels maintained?

Airborne particles, because of their small sizes, are measured in microns (0.00003937 in.). A micron is very small… putting this in perspective, there are 25,445 microns in one inch. Clean rooms are typically concerned with particles of 0.5 microns (0.000019685 in.) to 100 microns (0.003937008 in.).

The cleanliness level is controlled by laminar flow, constantly flowing the air along a parallel path, usually from the ceiling to the floor. The air is cleaned by passing it through high efficiency particulate air (HEPA) filters. In order to maintain the desired level of cleanliness, the room must be free of materials that will release particles. A positive pressure is always maintained in the higher class clean room; e.g., a Class 5 clean room will be maintained at a higher pressure than the Class 6 anteroom, which will be at a higher pressure than the outside hallway.

Resistance to Popular Disinfectants

Some Armstrong ceilings such as  Bioguard paint has enhanced resistance to disinfectants including Hydrogen Peroxide and Chlorine. Thus product can be used in areas with popular cleaning-disinfection operation.
