Framing Systems
The first step in configuring a modular office is to identify the best framing system for your application. The OmniFlex Plus system is ideal for most applications as it combines an attractive appearance with a high level of functionality, but Portafab offers a number of different systems specific applications.

Wall Panels
Once a framing system has been identified, the next step is to determine what type of wall panels you want for the office or enclosure. Portafab’s line of Fire & Sound panels are ideal for the majority of inplant office and enclosure applications because they meet most building codes and provide excellent sound reduction and thermal insulation. Hardboard panels, steel, and fiberglass panels are also available and there are a number of different finishes and core options within each line.

Roof & Ceiling Systems
Most offices will utilize a 22 gauge corrugated “B” deck painted and cut to length that supports a drop ceiling of 2′ x 4′ mineral fiber board ceiling tiles on a white steel grid system. Optional ceiling tiles, insulation, and support beams are available as required by the application.

With the structure in place, one can turn to specifying the type of door they need and how many entrances are needed. Standard doors are 20 gauge 3070 and 6070 models with or without glass. Stock options include door closers, aluminum thresholds, knob or lever locksets, door louvers, and kickplates. Of course, offices and enclosures can be outfitted with everything from aluminum storefront models to impact or roll up doors.

Most offices can then be outfitted with our standard 1/4″ thick tempered safety glass windows in either 4′ or 2′ widths and 3′ heights. Utilizing 6′ tall windows has also proven to be popular for team and meeting rooms and we also offer sliding windows and a variety of glazing options.

Electrical & Lighting
With Portafab’s modular wiring package, your inplant office will be outfitted with everything it needs for simple installation. You will need an electrician to bring power to the circuit breaker box and make the conversion from hardwire to modular loop, but otherwise the set up is easy. Simply specify the number of outlets, switches, and lights that you need and we’ll do the rest.

Climate Control
To complete your office or enclosure, we offer a variety of HVAC units, air conditioning units, and baseboard heaters. Wall panels can be modified before shipment to include a framed opening for these units.

The following steps outline the design considerations that go into a typical modular office or enclosure. Customized solutions, however, can be created to meet all types of requirements. From offices built on forkliftable bases to those suspended on a second story mezzanine, Portafab can create a solution for your needs.
