Modular Hardwall Cleanrooms

Hardwall cleanrooms provide a clean, protected, and well-structured environment. With decades of experience, we offer a range of modular cleanrooms to meet your cleanliness specifications. Our cleanroom components are prefabricated and completely modular, allowing for a flexible solution in your cleanroom processes. Cleanrooms by United takes pride in providing solutions for all aspects of your project, including installation, which the end user or a factory-trained crew can complete.

Benefits of Hardwall Cleanrooms

Our factory-prefabricated hardwall cleanrooms offer a variety of benefits to improve your overall cleanroom needs, some of which include:

Flexibility
Future expansion and upgrades
Easy relocation capabilities
Permitting available in all 50 states
Less expensive than standard sheetrock
Less disruptive to day-to-day operations
Quick expert installation, usually in just a few days (if needed)
Environmental control system implementation (existing HVAC systems can be incorporated in some cases)

In addition, our hardwall modular cleanroom systems come factory supplied with pre-wired, UL-classified raceways. These built-in raceways provide a flush interior surface for electrical outlets and phone/data wiring. This eliminates the mess of cutting and sanding drywall onsite and minimizes construction time and facility disruption. Our raceway extrusion can also be used as a service chase for water, compressed air, etc.

Modular Hardwall Cleanroom Construction

CBU provides a wide variety of material and finish options for your hardwall cleanroom needs. These options are based on a 4” thick panelized wall system supported by clear anodized aluminum extrusions. The standard panels for our modular hardwall cleanrooms are double-faced vinyl wrapped with gypsum on both sides. Panel sizes are nominal 4’ wide with heights of 8’ and higher. Some of the material and finish options available for our hardwall cleanrooms include:

Standard Vinyl: Our standard vinyl is non-shedding, easy to clean, and ideal for most hardwall modular cleanrooms.
FRP (fiberglass reinforced plastic): A chemical-resistant FRP finish is better suited for pharmaceutical modular cleanroom applications or other environments where microbes may be present.
Aluminum Clad: Aluminum-clad wall finishes are perfect for hardwall modular cleanroom applications involving human tissues or implantable medical devices due to aluminum’s natural ability to reduce microorganisms' presence and growth.
Heavy-Duty Ceiling & Roof: Made of heavy-duty steel, modular hardwall cleanrooms feature a T-grid to house filters, light fixtures, and tiles. Our ceiling and roof system is supported by a corrugated steel deck, panel roof, or structural steel supports.
Filtration Systems: We offer various cleanroom airflow designs to meet ISO 14644-1 requirements using single-pass or recirculating systems with unidirectional or non-directional airflow.

Our modular cleanroom doors and windows are pre-hung for quick and easy installation. For improved look and performance, our return air cutouts are framed in aluminum extrusions. All electrical wiring is concealed inside wall post cavities for outlets, light switches, conduits, etc.
