Cleanroom Windows

Several cleanroom window options are available, ranging from the conventional fully flush rectangular shape window to the semi-flush round corner window.

Kwang manufactures a number of standard cleanroom window units that integrate seamlessly with its modular wall and ceiling systems. Windows can be hermetically sealed while insulated glass units or double flush glazing can be easily incorporated into most designs. Cleanroom windows can also be integrated into return air walls to minimize any air flow disruption. 

Available window sizes will depend on the wall system being utilized, but various sizes are available and easy to integrate into most applications.


Viewing panels design and location within a clean room impacts workers’ comfort and operational efficiency. With viewing panels strategically positioned in between two separate rooms, operators in each room can have visual contact and communicate without leaving their respective location. Windows are often located in visiting and inspection halls for aesthetic reasons but also to enable supervision of tasks without disrupting operations and strict protocols for admittance into control areas.

Our glass is tempered therefore in the event of breakage, it shatters in rough pieces, with no sharp fragments. Laminated glass or polycarbonate is used when there is any risk of impact. Windows can also be coated to filter wave lengths in areas where decontamination is performed using ultraviolet light (for example in optics).

Another reason why doors and windows are critical features of a cleanroom is because contaminating particles can collect on frames, sills and fasteners, thus complicating cleaning processes. Depending of your needs, windows can be completely flush or semi-flushed against the wall panel.



Fully flush windows are flat against the modular wall. The absence of edges makes them easy to clean, since there are no corners to collect dust particles and micro-organisms.


The most economical solution for cleanrooms with less stringent classification applications. The semi flush window has a small rubber edge that does not attract particles and is easy to clean.
