Choose Your Panel

PBI’s versatility allows you a choice of wall panel designs and finishes. Our modular walls can be expanded polystyrene. We also offer a one hour fire rated core safety barrier made of steel studs and mineral wool.

At the panel joints, you can utilize our exclusive 1” wide vinyl divider strip or a conventional aluminum extruded binder post.

Our surfaces are limitless. Our most popular 1/2” vinyl covered drywall is great for fire, sound and cost. We also utilize aluminum, steel, hardboard, fiberglass reinforced plastic (FRP) porcelainized steel, plywood and virtually any type of surface you can laminate.

Our system is the most versatile. While we are happy to supply you with a standard “off the shelf” 8’ x 10’ structure, we have the capability to make any size structure to within a 1/4” tolerance.

The decision to go with Panel Built resulted in a flexible (floor plan) office addition and reduced the loss of floor space to almost nothing; while allowing an expansion that we needed.
