About National Partitions

Since 1967 National Partitions™ has been the industry leader in the application of economical modular design techniques as used in the construction of prefabricated interior offices (in-plant offices) , manufacturing rooms, environmental rooms, clean rooms and industrial wall systems.
No one has built more prefabricated rooms than National... As the pioneers in industrial modular construction we conservatively estimate that we have produced over 60 million square feet of our products. This makes us the largest and most preferred manufacturer in the nation by far.

Many successful companies are discovering that construction is an area in which they can gain a competitive edge through increased efficiencies and lower costs. With modular construction from National Partitions™, you will be able to reduce your costs, improve your productivity and strengthen your control of overall operations costs. Our products are found in manufacturing plants, warehouse and distribution centers, on military bases and in educational systems, among other industries.

No project is too small or too large ... our individual project range is from a few thousand dollars to well over a million dollars.

At National Partitions™ our philosophy is "Better Products... Lower Prices", and when compared to all other building methods, we are... "FASTER". Find out for yourself why we are the leader in the modular construction industry. An area manager or local distributor can quickly provide a budgetary proposal tailored to your specific requirements.

HiWall Partitions

HiWall allows you to divide industrial plant areas economically.

Constructed of 26 gage, G90 hot-dip galvanized facings with baked-on acrylic enamel. Utilizing ThermalCore insulation with optional urethane insulation for higher R-values.

Modular Office Partitions

Fully fabricated wall panels mean construction times are a fraction of conventional methods with substantially reduced mess and plant disruptions. Designing to specific industrial requirements with superior manufacturing and materials allows National to meet tough sound control conditions, as well as fire ratings and insulation.

Environmental Rooms

Environmental Rooms for high quality manufacturing meet the rigorous standards of today's modern processes. These rooms are able to precisely control temperature, humidity and air particulate to exact required levels.

Clean Rooms

National Partitions' clean rooms solutions hold many advantages including:


Our wall systems can be constructed to meet your exact requirements or preferences using a multitude of surfaces including steel, fiberglass reinforced plastic, high pressure laminated finishes and more...

Our modular construction will provide your organization with cost savings in design, construction and maintenance. Further systems may qualify for the the accelerated depreciation of 7 years vs. 39.5 year for conventionally constructed facilities. Consult your accountant for qualifications.

Our designs typically reduced construction time by some 35% compared with other construction methods.

The nonprogressive, fully fabricated panelized wall system design allows the room to be modified, expanded or moved with minimal amount of manpower or facilities interruptions. This system coupled with our WirePak modular wiring (which can be utilized for all electrical wiring including FFU HEPA filters) offers the most flexible building system available.
