Cleanroom Design and Constuction

CZT I - Hardwall Cleanroom

The CZT I hardwall cleanroom is pre-engineered to join ceiling, floor and mechanical components to provide complete control of critical environmental conditions. The system can be designed to your specific configuration and cleanlinessrange from ISO Class 5(Class 100) to ISO Class 8 (Class 100,000) With upgrades such as raised floor, ULPA filters, flush mounted window and door frames and your selection of surface finishes you will easily be able to achieve ISO Class 4 (Class 10). The hardwall cleanroom wall panels are press fitted into an aluminum or steel stud to form an airtight sealthat providetemperature, humidity and particulate control. The standard system is able to accommodate wall heights up to16’ and the standard 3" thick wall system offers loadbearing capabilities. The non-progressive design makes it quick and easy to expand, modify or move finished cleanrooms.

The standardsmooth hardwall cleanroom wall panel construction starts with an outer skin of conductive aluminum, painted steel, fiber reinforced plastic (FRP) or smooth Vinyl. Next comes a layer of polystyrene and the cleanroom wall panel is finished with one of the above mentioned outer skins. Add a layer of ½” gypsum between the outer skin and the polystyrene and you have a “Fire and Sound wall system certified to meet a certified Class A structure. If you have additional sound dampening requirements we can add an additional layer of sound dampening panels between the outer skin and the gypsum. Standard colors are white, champagne and grey. We can offer optional specialized colors.  We have been called upon to provide a flat black finish on all interior surfaces for one of our Aerospace customers and were also able to provide a black surface on interior of the cleanroom panel and a white surface on the exterior. All factory finishes offer the same cleanliness and cleanability as is required for all cleanroom surfaces.


To meet the critical needs of the microelectronic industry we offer aluminum composite wall panels that are non-outgassing, non-particle shedding and anti-static. The panels are either ¼” or ½” thick with an aluminum honeycomb core. This system also has a non-progressive design for easy modification.


With the ever increasing regulations of the biomedical, pharmaceutical, and life science industries the requirement for an aseptic cleanroom are becoming more critical. We offer a hardwall cleanroom where the architectural finishes are designed to be smooth, easy to clean, have minimal ledges and joints and be installed with radius corners for ease of cleaning. The wall panels are made with aluminum honeycomb cores and skins that are non-hygroscopic and are corrosion resistant. The surfaces withstand repeated cleaning and sanitization with various chemicals and are resistant to sustaining microbial and fungal growth. Special features are seamless panelized ceiling, flush mounted windows and doors.


We also offer seismic design with drawings Wet Stamped to your location. All of our cleanroom components are custom fabricated for ease of installation. You no longer have to put up with sheetrock dust and major construction contamination when building your cleanroom.  Our knowledgeable installation crew will have you operating in a cleanroom as quickly and efficiently as possible with the minimum of disturbance to existing processes. We install clean-rooms throughout the U.S. and Internationally.
