Metals in an expanding variety of finishes and formats give architects a near-limitless palette for aesthetic expression—without compromising building performance. Here's a quick sampling of six great claddings. TECU Brass KME This CuZn15-grade copper and zinc alloy has been specially designed for use on façades. Weathering changes the original reddish-gold color of the surface, with each façade developing its own unique characteristics. After the initial matting, the surface takes on a greenish brown tone, which slowly turns grayish brown before evolving into a dark brown-anthracite color. On sloping surfaces, a patina typical of classical copper develops. The material offers outstanding mechanical abrasion resistance, extremely high corrosion resistance and durability, as well as excellent stability and material rigidity. It can be cold-shaped and soft-soldered. Alpolic/fr Fire-Retardant Core Alpolic Fire-retardant cladding is typically required in buildings that exceed a minimum height as specified by applicable codes. Offered in an extensive choice of options, this affordable material is a popular choice for external cladding. It is composed of a fire-retardant thermoplastic core sandwiched between two thin metal skins. Available in several finish options. Reynobond ACM Reynobond This aluminum panel features a polyethylene core that adds strength and rigidity to the coil-coated aluminum panels. This maximizes its flexibility and formability, while maintaining a light weight for easy installation. Also available with a fire-retardant mineral core. CWP 600 Wall Panel Englert The Englert CWP 600 is a sequentially installed, gasketed wall panel system that employs integral weather stripping and hidden fasteners. Like the 200 and 400 series, this wall panel system can accommodate intricate corners, curved walls, simple fascias, and various soffit and parapet conditions. All panels are assembled using proprietary internal extrusions that provide a rigid perimeter, producing a stiff panel that resists deflection and modulation. Eco 160 Electro Range Sapphire Aluminum Anodized aluminum is UV-resistant and will not peel, chip, flake, or blister. Because it is a translucent coating—not an opaque powder-coat—it maintains a deep metallic finish. Herringbone 3 GKD This flexible, stainless steel mesh can be used for walls, column covers, partitions, and more.

A room-filling parametric design makes its way from the classroom to Austin's famous music festival.When Kory Bieg and his students at The University of Texas at Austin School of Architecture began working on Caret 6, they had no idea that it would wind up at this year’s South by Southwest (SXSW) music and arts festival. But the rippling, room-filling installation soon took on a life of its own. Within months, Bieg’s undergraduates—who had little previous exposure to digital design—had designed and fabricated Caret 6, and assembled and disassembled it twice, first at the TEX-FAB SKIN: Digital Assemblies Symposium in February, and then at Austin’s most famous annual gathering in March. Caret 6 developed out of a research studio taught by Bieg, who is also associate director of the regional digital fabrication and parametric design network TEX-FAB. Selected to chair TEX-FAB’s annual design competition, Bieg knew that he would soon face a problem: how to display the winning entry in a gallery much larger than it. He put his students to work on a solution. “The idea was to create a kind of counterpoint to the winning entry. [We] needed to fill space,” said Bieg. At the same time, the studio would teach the fundamentals of digital fabrication. “It was really just an experimental exploration of what these tools could produce,” he said. Caret 6’s white and grey diamond-shaped cells cascade from a central catenary vault with three column bases. Two secondary vaults project from either side. The front face of the structure flows down to the floor. “The idea is, we didn’t actually know who the winner [of TEX-FAB: SKIN] would be,” said Bieg. “We wanted to design a ground surface that was modular so that we could replace some of the cells with bases for their models.” The 17 students enrolled in Bieg’s course first created individual study models of aggregations and weavings amenable to digital fabrication. In an internal competition, they narrowed the field to three. Bieg broke the studio into teams, each of which experimented with creating volumetric versions of the designs. In a departure from typical parametric installations, Bieg and his students decided to stay away from patterns that gradually expand and contrast. “Our interest was not [in] doing subtlety, but local variations that are quite abrupt, like going from a large cell to a small cell,” said Bieg. “So part of that was a result of the way we structured it. Instead of aggregating cells, we designed a series of ribs.” The primary ribs form the vaults’ seams, while the secondary and tertiary ribs divide the structure into asymmetrical pockets. Halfway through the semester, Bieg called Alpolic Materials, whose Aluminum Composite Material (ACM)—a thin polyethylene core sandwiched between two sheets of aluminum—he had worked with on an earlier project. Alpolic agreed to donate supplies for Caret 6, “so we refined the design according to the material we had,” said Bieg. He also drafted students from UT engineering to calibrate the structure’s thickness, scale, and cantilever distances. “It kind of just evolved from these different processes coming in,” said Bieg. Back in the studio, Bieg’s students used 3ds Max for form studies and Kangaroo, a Grasshopper plug-in, to fit the tessellated diamond pattern to the vaults. They also used Grasshopper to develop an assembly system of binder rings, bolts, and o-rings. Bieg and his team fabricated the installation using UT’s CNC mill. They cut the vault pieces out of Alpolic ACM. The elements closest to the floor are polypropylene, while the intermediary pieces are high-density polyethylene. The students assembled and disassembled Caret 6 manually. At first, they tried working with a QR-code system, scanning each component to determine its location. When this took too long, they projected a digital model of the form on a screen, then called out each piece by number. For SXSW, where they had only six hours for assembly, they subdivided the structure into sections that could be quickly recombined on site. Caret 6 travels to Houston in September, where it will rejoin the entire TEX-FAB: SKIN show. But while the installation has already moved beyond its original context, Bieg insists that it remains rooted in the SKIN competition brief, which focused on building envelopes leveraging metal fabrication systems. “[Caret 6 is] not really a program per se, but more of an experiment about the same concepts that were part of the exhibits at TEX-FAB,” he said.

A coffee stand prototype explores new possibilities for small-scale modular construction.As part of a push to get its products into the hands of young architects, the Alpolic division of Mitsubishi Plastics sponsored a spring design/build studio entitled “Rapid type” at the California College of the Arts (CCA). The goal was for 15 students, led by CCA adjunct architecture professors Andre Caradec and Kory Bieg, to explore new design uses and assembly techniques for Alpolic aluminum composite materials (ACM), which are most commonly used for exterior cladding and signage. The students had at their disposal not only the school’s resources, but also those of Bieg’s San Francisco-based design and fabrication firm OTA+ and Caradec’s Oakland-based design and fabrication firm, Studio Under Manufacture (SUM). Given the college’s location at the nexus of a burgeoning San Francisco food truck scene and students’ proclivity for caffeine, the team landed on design of a mobile coffee service unit as a means of testing Alpolic’s limits. The team envisioned a structure that was reliable and cost-effective while bringing a higher level of design and prefabrication to the food truck industry, which has received a boost in Northern California due to relaxed permitting and code requirements. After feasibility and marketing studies, the team began to design a rolling steel structure wrapped in a waffle grid of Alpolic. The cart would shade employees inside while incorporating a wraparound counter that would allow customers to linger or talk shop with the barista after placing their order. Though an encircling plywood base supports the grid structure overhead, the interior is floorless; employees stand on the ground at the same level as patrons. “It also makes cleanup easier,” jokes Caradec. The 9-by-11-by-8-foot structure sits on industrial casters, allowing it to be pulled into place by a vehicle or by hand. The team designed the cart’s waffle grid in Rhino, with each rib section connecting the corresponding perpendicular section with a long notch. After assembling a scale cardboard model, fabrication of 80 ribs from sheets of 62-by-196-inch Mist White Alpolic began in SUM’s shop using a three-axis CNC mill. Exterior plywood shear panels and ribs for the counter and service window structure were milled on the same machine. Those ribs were then wrapped in waterjet-cut 16-gauge mild steel to create the completed work surface. Once interior Alpolic milling was complete, exterior plywood was installed over the hollow steel frame and final measurements for exterior ribs were verified before milling. After interior and exterior structures were built, the countertop structure was put into place. The entire project was manufactured and assembled in less than a week—in time for the students’ final review, complete with coffee service. Caradec’s firm recently applied a similar concept to a prefabricated studio. The design is the workspace version of the coffee station, an 8-by-10-by-8-foot-high office for a writer who requested that the space allow him to recline, sit, and stand during the workday. Like the coffee station, the box is built with white Alpolic sheets, but these have been routed on one side, then folded to create a faceted shape. Because of the panels’ construction, they create a hermetic exterior even after folding. A 14-inch marine-grade teak window wraps the structure, creating visibility from any position. The coffee station prototype design has already received attention from investors interested in putting a line of prefabricated food service stations into production. And other iterations, like the writers studio, could create a new generation of prefabricated structures for a range of applications. “The design can be based on the environment it’s going into,” says Caradec.
