To prepare for adding convenience stores in southern Florida, Cumberland Farms commissioned Building Envelope Systems to design a structure that was functional and could be quickly built.

To prepare for adding convenience stores in southern Florida, Cumberland Farms commissioned Building Envelope Systems to design a structure that was functional and could be quickly built. The primary objective was to standardize a building that could be reproduced quickly and efficiently. Additionally, a stable, airtight internal environment that performs economically was required for the model store.

Building Envelope Systems created a structural steel frame store enclosed with insulated metal panel assemblies manufactured by Kingspan Insulated Panels. The rainscreen design is a dry fit that prevents weather from penetrating the joints. Structural steel was cut to dimension off-site and the wall panels were sized during the manufacturing process.

In a single pass, Kingspan's KarrierPanel metal wall panels become the mounting for the exterior façade and the finished interior wall. This enabled the building crew to enclose the job sooner and allowed work to begin on the interior installation of refrigeration and wiring.

One wall system contains the interior wall, insulation, moisture and air barrier system and exterior cladding. It took four days after the steel was erected to enclose the job, a 4,000-square-foot building exterior. Off-site manufactured systems benefit from tight seals at the joints and hidden fasteners. The Polyiso foam core inside the KarrierPanels improves energy efficiency and provides a high R-value.

Brett Miller, of Building Envelope Systems, says his company designed the building for construction speed. "KarrierPanel is easy to put up for a fast enclosure," he says. "It's roof ready and you can really put anything you want over it."
