BY HENRY BURKE Brought to you by Little Things Mean a Lot Architects know as well as anyone that the smallest details can make or break a project. Whether in terms of performance or aesthetics, the big things and grand strokes of design all are built on a foundation of small details. Without strict attention to the so-called little things, a project can’t be expected to JULIE PAWUK reach its full potential. At CENTRIA, this is a concept we understand very well. Beyond our dedication to manufacturing excellence in the building components we produce, we also know that getting just the right finish, color, or profile on a panel can mean the difference between a building fulfilling its designers’ intent or coming up short. In “Sweating the Details” on page 12, CENTRIA Director of Marketing Rick Brow discusses this attention to the little things and how it drives our product development. Having a great individual panel is one thing, but ensuring they assemble correctly together as part of a system is one of those foundational details we focus on. We have always felt that open dialogue between all parts of the building team — architect, contractor, owner, and manufacturer — creates the best results. Listening to our end users is a pillar of the way CENTRIA operates. To help further that dialogue with the building community, we are proud to announce the launch of CENTRIA’s new blog, The Reveal. This new outlet is designed to leverage CENTRIA’s expertise with exterior metal building products and services to provide architects, owners, and contractors with relevant, engaging educational material. The blog is filled with eye-catching case studies, technical information, and much more. Be sure to check out The Reveal at blog.centriaperformance.com. As with everything else we do, we took time to focus on the details with The Reveal and we are proud of the resource we have built and excited to see where it goes. We encourage you to continue the dialogue with CENTRIA and share your project stories, aspirations, and ideas. For more information on CENTRIA, visit www.CENTRIAperformance.com/metalmag.

Bowen & Associates PRODUCT SPOTLIGHT 5 Changing Direction Formawall® Graphix SeriesTM with Directional Reveals Formawall Graphix Series with Directional Reveals changes the landscape of the insulated metal panel (IMP) by introducing the option to add horizontal, vertical, and diagonal reveals within a single panel for a superior level of customization. CENTRIA’s original Graphix Series offered an economical solution to create some of the most distinctive panel aesthetics on the market. The addition of Directional Reveals greatly expands the customization features of Formawall Graphix Series, creating the option for multiple horizontal or vertical reveals within a single panel, a combination of horizontal and vertical reveals within a single panel, or the new Sloped Reveal, which can be placed at nearly any angle along the face of the panel. From an aesthetic standpoint, the marquee attribute is the addition of Sloped Reveals. These reveals can be applied to both horizontal and vertical panels. The innovative reveal creates the appearance of two separate panels, divided at an angle the architect chooses. Sloped Reveals can be designed with various color and texture combinations, including smooth and embossed face textures and CENTRIA’s vast color palette. Of course, the Directional Reveals product line also includes standard horizontal and vertical reveals. The product’s most impressive feature is the ability to combine these reveals regardless of whether it’s a horizontal- or vertical-oriented panel. This allows architects to create the look of up to 24 separate panels within a single module. With any reveal composition, the panels can be designed with CENTRIA’s wide array of colors and coatings — including multiple colors on one panel — as well as smooth and embossed face textures. Panels are available from 10" to 40" wide and 4" to 20" long, with size limitations based on face texture. Thermal performance is at the core of Formawall Graphix Series panels. Formawall panels utilize a factory foamed-in-place polyisocyanurate foam core that reduces insulation gaps within the panel, while providing a thermal break between metal face and liner to eliminate heat/cold transference. The Formawall Graphix Series with Directional Reveals product line is available in 2", 2.5", and 3"-T thicknesses. Formawall panels have set the standard as far as performance with unique pressureequalized and vented dry seal joinery. The optional Formawall PE Vertical Seal Plate also adds multiple lines of defense against moisture intrusion at the vertical joint of a horizontal panel in the form of integral gaskets, a vented drain channel, and non-curing butyl seals. Formawall Graphix Series with Directional Reveals provides a significant reduction in opportunity for air and water infiltration. With the ability to reduce the number of actual joints on a project, Formawall Graphix Series is the best choice for any project that requires relatively small panels, Flemish bond patterns, or diagonal reveals.

Metalmag | Summer 2015 1 COVER STORY Cleveland Rocks Ohio’s Hard Rock Rocksino Northfield Park celebrates music, past and future. BY HENRY BURKE Around the world, there are few brands as well recognized as Hard Rock. The iconic logo immediately conjures a familiar atmosphere. Over time, Hard Rock International has grown far beyond its restaurants and popular T-shirts. In recent years, hotels and casinos have become a central part of the Hard Rock family of properties. For the first in a line of “Rocksinos” that would offer visitors a mix of gaming and music, Hard Rock went to the legendary home of the Rock and Roll Hall of Fame: Cleveland, Ohio. Built in nearby Northfield Park and opened in December 2013, the Hard Rock Rocksino was designed around an arena rock theme. While it clearly reflects the heritage of its surroundings in Ohio, the Hard Rock Rocksino Northfield Park also provides an atmospheric template for similar properties to come. “Hard Rock International is very specific with what they determine to be ‘the Hard Rock vibe,’” explains David Bowen, principal at Clevelandbased Richard L. Bowen & Associates, the architect of record on the Hard Rock Rocksino. “It’s a certain feeling. Their focus is delivering an aesthetic and creating that feeling you get when you go into a Hard Rock.” It’s a feeling that has evolved over time, says Michael Mangini, design director for Atlantic City– based SOSH Architects, the design 2 Summer 2015 | Metalmag architect and interior designer on the project. SOSH has a long-standing relationship with Hard Rock International and was brought on at the concept stage. “Hard Rock is a powerful brand, but it is not a brand that is stuck in the past,” Mangini says. “With the Hard Rock Rocksino project, we’re celebrating the continuation of that brand into the modern age.” aesthetic,” Bowen says. “The material, the glazing, the lighting, and everything else all worked together to give visitors the impression that they are walking into a special place with a rocking vibe.” Using metal in combination with other materials was key to achieving the design goals. “Basically, casinos can just be boxes, Culture of Cleveland Along with embodying the Hard Rock International brand, the new Hard Rock Rocksino also was intended to represent the local ethos. “We wanted to celebrate the local vernacular and culture of the location,” Mangini says. The design team began their work with extensive research on the Cleveland area and Ohio and the people who live there. “We tried to celebrate the history of music from the Cleveland perspective. There was a lot of local collaboration that influenced the design directly.” Materiality played a big role in achieving the modern, hip aesthetic of the Hard Rock Rocksino, and metal was a big part of the visual feel. The project utilizes CENTRIA’s MetalWrapTM Series insulated composite backup panels behind masonry, single-skin concealed fastener metal panels, and metal composite material (MCM) panels. “[Metal] was definitely a part of the and we didn’t want that. The changing of materials really adds to the interest. Coming down the processional to the porte cochere into the entrance of the building, you can feel the vibe out on the street.” Right on time Though the Hard Rock Rocksino had grand aesthetic goals, a fast-tracked schedule meant that the design and Metalmag | Summer 2015 3 Getting warmer Metal’s ability to take on color also proved to be a major advantage. “Brock Milstein (Chairman, Hard Rock Rocksino Northfield Park)” had a very specific attention to detail when it came to having the building have a certain warmth to it,” Mangini says. “We went through at least half a dozen full-scale metal panel mockups to really nail the color and texture from the blocked metal panel. Every detail was mocked up before we pulled the trigger.” CENTRIA’s innovative Allusion print coating system enabled the panels to achieve just the right finish. “It gave us a great outcome,” Bowen says. “It accomplished what we wanted to accomplish. Metal was a great material to work with and it gave us that Hard Rock vibe on the exterior of the building. And from an installation standpoint, it went up very fast.” In operation now for more than a year, the Hard Rock Rocksino has earned rave reviews from the owners and local residents. It remains a draw and has brought new vibrancy to the community. “I am proud of the property and what it means to the community there,” Mangini says. “Northfield is a great community and the partnership between Hard Rock and the town is an excellent one. It has sparked a lot of interest, a lot of employment opportunities, and the community has done a great job. I think it’s leading to conversations about a possible expansion. It was a thrill to work on this project and wonderful to see what it’s brought to the area.” Hard Rock Rocksino Northfield, Ohio Architect: Richard L.

Its ability to install quickly helped the design and construction team keep with the tight schedule. HIGH note University of Tennessee’s modern Natalie L. Haslam Music Center gestures to the future. BY HENRY BURKE With roots going back to 1794, the University of Tennessee is one of the oldest public universities in the country. The institution has a great deal of pride in its many academic programs, and the UT School of Music in the College of Arts and Sciences is no exception. The School of Music’s primary emphasis is the development of the skills, concepts, and sensitivity essential to the professional life of a musician, whether that’s as a performer, composer, scholar, or teacher. UT’s existing music facility was built in the 1960s and was beginning to show the stress of age. It could no longer serve the needs of a program looking to the future and needed to be replaced. For the new, upgraded facility, the university turned to the designers at BarberMcMurry architects, the firm that designed the original music building half a century ago. The design team was made up of BarberMcMurry’s vice president and director of design, Chad Boetger, and its senior vice president and principal in charge, Kelly Headden, in collaboration with Blankenship & Partners president and principal in charge, Bill Blankenship. “The joint venture of BMa and Blankenship divided project responsibilities, with BMa serving as the project designer and Blankenship producing the majority of the construction documents necessary to execute the design,” Boetger says. Once assembled, the team went to work establishing a vision for the new Natalie L. Haslam Music Center. “Working closely with the university and the director of the School of Music, Roger Stephens, we developed a design philosophy that would guide the creation of the facility,” Boetger recalls. “It was Roger’s vision that the new music center be a representation of the creative arts in built form. It should speak to college students and inspire them in their study of music.” The architects sought a design that would capture the physical embodiment of music and provide light-filled environments connected to the campus to encourage creativity. “Concepts of rhythm, pattern, and repetition are conveyed in the detailing throughout,” Boetger says. The building houses 40 faculty studios and 45 practice rooms, as well as classrooms; administrative offices; and choral, orchestra, percussion, and chamber music rehearsal rooms. It is organized around a 420-seat recital hall and large band Metalmag | Summer 2015 5 room, each of which is three levels tall. Taking advantage of natural light and views, the faculty studios, classrooms, rehearsal spaces, and individual practice rooms wrap the exterior. Replacing a building that had stood so long on campus required striking a chord between embodying the future while respecting the past and integrating the building into its surroundings. “The site places the music center adjacent to an existing Art + Architecture building,” Boetger explains. “It is a modern, cast-in-place concrete building within a neoGothic campus.” Given the adjacency, the new music center respects the contextual massing, setbacks, and precedents of the A+A building while combining the brick and limestone materiality of typical campus structures within the composition. “The overall design provides a bridge between the modern, creative class and the traditional campus architecture desired by UT administration,” Boetger says. Metal surfaced as a material choice because it fit the numerous aesthetic and performance goals the project required. “Our client wanted a building with a modern aesthetic,” Boetger says. “We endeavored to create a building with clean lines and visual interest. Material selections were required to be durable, low maintenance, and cost effective. In addition, the building envelope needed to provide a high insulating value demanded by energy codes and LEED goals.” Sustainability is part of the DNA of the Natalie L. Haslam Music Center, which has achieved LEED Silver certification from the U.S. Green Building Council. Along with the insulating value and high level of recycled content that metal panels provide, the building collects rainwater for irrigation, utilizes regional materials, and features daylight harvesting. Formawall® Dimension Series® metal wall panels from CENTRIA contribute to a strategy that decreases energy consumption with an efficient HVAC system working in concert with a tight building envelope. “Metal was a natural choice to achieve a modern aesthetic, and it also met the criteria of being durable and low maintenance,” Boetger says. “By selecting a metal panel with integral rigid insulation, we were able to simplify the exterior building envelope system and achieve a cost-effective, energy-efficient design.” The design team was able to achieve an impressive result while working within the parameters of a budget appropriate to a learning institution. Along with its flexibility, durability, look, and performance, the economy of metal was important as well. “Meeting budgeted construction costs is critical to success,” Boetger says. “We were careful to plan the building to maximize efficiencies and leverage them to produce an impactful design. Working with the client, we selected materials and systems that would meet their goals for function, cost, and aesthetics.” The finished product speaks for itself, and the University of Tennessee is proud of the recently Natalie L. Haslam Music Center. “The overall reaction has been positive,” Boetger says. “The faculty are very complimentary of the building and student enrollment has surged. In addition, this building is among the greenest on campus, which is a reflection of UT’s commitment to sustainability. Working with Roger Stephens and the University of Tennessee to produce this special facility was a delight. Great design requires great clients, and we were extremely privileged to work with a very dedicated team with an inspired vision.” Natalie L.

BY BETHANY DZIELSKI Today, Crown Corr is an industry-leading subcontractor specializing in metal panels, custom metal roofing, glass, and aluminum curtain wall. The firm serves customers across the United States and Puerto Rico. In 1960, however, Crown Corr was a startup housed in Joseph Pellar’s basement. Before starting the business, Joseph Pellar was an ironworker, doing siding work in the mills. He originally started Crown Corr Erection as a labor contractor. After being contracted for the construction of the Burns Harbor Steel Plant, Crown Corr gained name recognition and grew rapidly, expanding beyond the basement office. Today, Joseph Pellar’s son, Rich, is principal at Crown Corr and continues to help run the business that his father started more than 50 years ago. “I started working for the company full time when I was 22 years old, but I started working summers at the company when I was only 13, earning a dollar an hour,” the younger Pellar says. With headquarters in Gary, Indiana, and additional locations in Texas, Georgia, and Washington state, the company has seen incredible growth over the past several decades. In 1976, when Rich Pellar first started working at Crown Corr, it was a $5 million business. Today, the company’s sales exceed $125 million. “We’ve grown as the architectural market has grown,” Pellar says. “But I attribute our success to almost going bankrupt in 1983, during the last recession. It forced us to focus, develop a more profitable business, execute correctly, and go after the right projects.” Crown Corr prides itself on offering single-source responsibility for its customers, including design, engineering, shop fabrication, and complete installation of all products offered. “Just give us the steel frame and we’ll get the job done,” Pellar says. “We work with the architect and design consultants to understand the vision for the building, and then we can take it from there.” With its in-house capabilities, Crown Corr controls the entire scope of a job. “We don’t subcontract labor,” Pellar notes. “We control everything we do, and that makes it easier for us to provide flexibility and ensure excellence.” Crown Corr specializes in stadiums and arenas, airports, convention centers, commercial office buildings, and hospitals. “We’ve done over 60 sports stadiums,” Pellar says. “We will do any size project in our backyard—within 200 miles—but when we go outside we’re primarily contracted for large projects.” A win-win partnership Crown Corr has partnered with CENTRIA and its predecessors since Crown Corr’s founding. The partnership has proved to be beneficial for both companies and the customers they serve. “CENTRIA is the leader in the architectural market,” Pellar says. “They offer products that have capabilities few other products have. We put those products to the test on applications and push their limits.” CENTRIA truly develops relationships with its partners, seeking to understand their needs and the needs of their customers. “[Vice President of Sales] Joe Urso knows more about the distribution side of the metal panel business than anyone else,” Pellar says. “He really understands his dealer network and how to make us successful.” “It’s really a win-win for everyone. CENTRIA provides good products, allowing us to create something that we can point to proudly,” Pellar adds. Rich Pellar is also an original member of the Dealer Advisory Council, a group that meets with CENTRIA representatives to advise on new products and improvements. At these meetings and throughout the year, CENTRIA educates the dealers on the architectural wall systems as well as on new building codes. “When it comes to educating their dealers about changes in new building codes and ensuring that we know what we need, CENTRIA is head and shoulders above the competition,” Pellar says. The partnership between CENTRIA and Crown Corr has resulted in many successful projects throughout the years. Several recent ones include work done in the San Francisco 49ers’ Levi’s Stadium, University of Kentucky’s Commonwealth Stadium, Houston’s William P. Hobby Airport, the Denver VA Hospital, MGM Grand Garden Arena in Las Vegas, and a recently won contract for the new Atlanta Falcons stadium. One notable recent project is the Miami Marlins baseball stadium. This expansive project showcases more than 200,000 feet of CENTRIA product, including Formawall® Dimension Series® panels, Profile Series Exposed Fastener and IW Series panels and EcoScreen® perforated screenwall. The new Marlins Park was the first ballpark in major league baseball to achieve LEED Gold certification for new construction. This 928,000-square-foot facility is the pinnacle of modern and energy-efficient design, featuring a retractable roof and glass wall, as well as other modern enhancements. Numerous steps were taken throughout the construction and design process to utilize sustainable and energyefficient materials and products. Due to the nature of the project, it was necessary for the design teams to utilize ecoconscious and hurricane-resistant materials in the stadium. CENTRIA products offer both sustainability and superior performance compared to competitors, and many of the CENTRIA products used in the project contain pre- or post-consumer recycled waste. “CENTRIA’s products were chosen because of their hurricane testing. They had to pass the stringent approval process of Dade County,” Pellar says. On a football or baseball field, teamwork is vital to the achievements of an organization. The success of the hundreds of CENTRIA–Crown Corr collaborations are a testimony to the value of teamwork in the built environment, too. Crown Corr and CENTRIA collaborated on the LEED Gold Marlins Park, the most sustainable ballpark in major league baseball. 8 Summer 2015 | Metalmag Metalmag | Summer 2015 9 PERFORMANCE Tech Bulletin History and Use of AAMA 508 and AAMA 509 CENTRIA’s FormaBond aluminum composite material (ACM) panels provide the rain screen wall cladding system for the Baylor Charles A. Sammons Cancer Center (Perkins+Will). BY KEITH BOYER, CENTRIA DIRECTOR OF ARCHITECTURAL WALL TECHNOLOGY Get to know the consensus testing methods for two important types of cladding systems. The relatively new American Architectural Manufacturers Association (AAMA) 508 and 509 documents can help define the design of either a pressure-equalized rain screen (PERS) system or a drained and back-ventilated system for the building enclosure. The road to developing these documents began in 2003. At that time many aluminum composite material (ACM) fabricators and designers were touting their systems as PERS systems. Some suppliers realized there was no clear definition of, or test protocol for, a pressure-equalized rain screen system in the United States. They also realized that many cladding systems were being assembled over poor air barriers such as unsealed exterior 10 Summer 2015 | Metalmag gypsum sheathing. A task group of ACM suppliers and fabricators was formed and, over a period of nearly three years, they developed and adopted AAMA 508-05. AAMA 508 In 2007, minor revisions were made to the method of measuring or observing the amount of water contacting the air barrier, and the standard became AAMA 50807: Voluntary Test Method and Specification for Pressure-Equalized Rain Screen Wall Cladding Systems. The standard set forth testing procedures for PERS systems. The tested assembly must be 8' by 8' and have an exterior rain screen (cladding) assembled over an imperfect air barrier with a cavity in between. The air barrier imperfections used in the test were set at 0.12 cfm/sf, which is four times the commonly accepted value set by the Air Barrier Association of America (ABAA) of 0.03 cfm/ sf at 1.57 psf. The imperfections were set at this level as a worst-case assembly, simulating unsealed exterior sheathing, since it is harder to equalize pressure with an imperfect air barrier. For the test, rigid clear plastic is used as the air barrier, and the imperfections are designated as a series of 1/8" diameter holes drilled through the plastic. To pass the test, the assembly, which includes the exterior rain screen, cavity, and imperfect air barrier, has to demonstrate the ability to equalize pressure to the exterior through vents designed into the cladding joinery. Per ASTM E1233, the loads are 100 three-second cycles from 5 to 25 to 5 psf. Pressure in the cavity must equalize with the exterior in less than 0.08 seconds. Additionally, a series of static and dynamic water tests are to be conducted on the system per ASTM E331 and AAMA 501.1 at a minimum pressure of 6.24 psf. Note that if higher pressures are desired, the job specification needs to indicate the test pressure. During these water tests, no more than 5% of the area (3.2 sf in the 64-sf panel) of the air barrier can be misted without any water streaming on the air barrier. In summary, a PERS system, including the cladding, cavity, and air (imperfect) and water barriers, needs to be vented enough through the cladding to equalize pressure to the exterior within 0.08 sec for a 3-second load cycle from 5 to 25 to 5 psf and allow only a small amount of water that can mist (without streaming) a maximum of 3.2 sf of the air barrier in an 8' by 8' test. The system must also be compartmentalized, which requires the number and geometry of the vents to be designed so that the product performance is the same in any compartment. By passing AAMA 508-07 at the specified test pressures the wall cladding system meets the definition of a PressureEqualized Rain Screen. AAMA 509 Once the AAMA 508 document was in place for a few years, it became evident that there were few systems in the U.S. market that were using the AAMA 508 test protocol. Another AAMA task group was formed to develop a test protocol for drained and back-ventilated rain screen wall cladding systems, a category thought to encompass a larger sampling of cladding system designs. Many more companies were represented in the development of this standard. The group did not come to a consensus on pass-fail criteria. Instead, they agreed on a test and classification method in an effort to offer information to the building envelope designers: AAMA 509-09, Voluntary Test and Classification Method for Drained and Back-Ventilated Rain Screen Wall Cladding Systems. Like AAMA 508, the AAMA 509 test protocol uses an 8' by 8' assembly and a clear plastic air barrier into which holes were drilled to create imperfections. The main difference is that there is a gutter at the base of the wall to collect any water that contacts the air barrier and runs into the gutter. Mechanical provisions were also used to measure the amount of air flow through the cladding at 1.57 psf. Hence two main data points are reported: 1. The amount of air flow through the cladding (more is better to allow for drying). 2. The amount of water contacting the air barrier (less is better). Again, there was no consensus on pass-fail criteria for this protocol due to the multitude of cladding types represented in the task group. The results for the systems tested showed a wide range of data, especially in the amount of water collected. After four 15-minute water tests (static at 6.24 psf and 12 psf and dynamic at 6.24 psf and 12 psf), the amount of water that contacted the air and water barrier varied from several gallons down to a fraction of an ounce. The result is a system classification for vent potential, or “V” classification, and a number representing the water bypassing the cladding, or “W” classification. The higher the vent class, the better the drying potential, and the lower the water class, the less water on the water barrier seals. CENTRIA’s FormaBond II had significant venting at 7.85 cfm/sf through open yet protected joinery, while the water collected on the air/water barrier was only 0.01 oz/sf total in four water tests. This results in a V4/W1 classification. The results are intended to provide the design team with data to serve as a guide to the design of the air and water barrier and base drainage system, as well as design of the rain screen cladding. The job specifications should require that all bidders conduct this test so that the proper test performance data is available to the design team. This data can also be used to compare one system to another. Metalmag | Summer 2015 11 THE CENTRIA ADVANTAGE The Formawall IMV detail (left) provides an all-metal aesthetic versus typical gasket vertical joints, not to mention added thermal efficiency. Sweating the Details Details, details, details. They can make a product or project something special, or they can become a nuisance and develop into a long-term problem. BY RICK BROW, CENTRIA DIRECTOR OF MARKETING systems. This unique panel clip serves several functions. It helps with panel to panel registration; mechanically attaches the panel to the support system; and permits movement of the panel caused by thermal expansion and contraction or seismic situations. The same panel clip and joinery are used for both horizontal and vertical applied Concept Series and Cascade panel systems. This allows the various profiles (eight Concept Series profiles and seven Cascade profiles) of each panel to be interchanged. Without this type of clip attachment, concealed fastener panel designs may suffer from panel installation misalignment. Also, thermal stress on the panel can elongate the fastening hole, loosening the panel attachment, or introduce visual panel deformation, surface waves, or oil canning in the panel face. At CENTRIA, we pride ourselves in developing superior products and product details that meet the growing demands for performance, aesthetics, and sustainability. Sometimes, we all take for granted the simplest product detail and how it improves the appearance and performance of a product. Take, for instance, the Formawall® Dimension Series® panel joinery and panel end condition. While most pros who have used our panels understand how our pressure-equalized horizontal joint works and performs, many may not recognize the rather obscure transition between the sloped drain shelf and the panel trimless end. The trimless end actually is notched and bent to fit under the sloped drain shelf. This helps provide a tighter seam, eliminates gaps of foam exposure, and deters moisture entry behind the trimless end. Without this special attention to detail, there would be obvious aesthetic and performance issues. 12 Summer 2015 | Metalmag Advanced protection Providing thermally efficient detailing is among the many challenges presented when working with IMPs. It is often too easy to short-circuit the thermal efficiency of the panel in perimeter detailing because IMPs are one of the few building products that provide a single-component solution for air barrier, moisture barrier, vapor barrier, and thermal barrier along with an exterior wall surface. A simple window head detail with a buy out window can close off the bottom of a panel but result in thermal conductance by the closure flash or extrusion, leading to reduced thermal performance and, under certain circumstances, condensation behind the metal IMP. CENTRIA has developed a series of IMP details that we call advanced thermal and moisture protection (ATMP®) technology. The ATMP details are designed to improve the Staying in line Clever clip Another hidden detail gem is the panel clip that is used with our concealed fastened Concept Series® and Cascade™ metal panel inconsistent with the horizontal metal joinery, and CENTRIA’s research with architects and designers indicated that this detail should be improved. Recently, CENTRIA introduced a new detail for the Formawall Dimension Series and Formawall Graphix Series™ horizontally installed insulated metal panels. The Formawall IMV (insulated metal vertical) detail improves the aesthetics of the vertical joint by providing a reinforced metal spline that is installed between the panels. The metal spline is available to match the panels, or it can be provided in a complementary color. The reinforcing material is an EPDM foam adhered to the metal spline. Notches in the foam of the insulated metal panel (IMP) are placed in the factory and allow for field tolerance. As an added benefit, the IMV detail provides a slight improvement in thermal efficiency over the traditional gasket detail. CENTRIA’s Formawall Dimension Series panels feature trimless ends, which are notched and bent to fit under the sloped drain shelf for a tighter seam. For almost 20 years, the standard joinery between horizontally erected insulated metal panels was a returned edge (trimless end) at the panel end with an applied black gasket between adjacent panels. While this detail prevented moisture intrusion, it was aesthetically The concealed fastener panel clip, used with CENTRIA’s Concept Series and Cascade metal panel systems, permits movement of the panel due to thermal expansion or seismic activity. Window and wall integration is an important part of CENTRIA’s ATMP technology. performance of insulated metal panels at perimeter conditions and adjacent to other wall materials. Foam-insulated extrusions and continuity detailing are used to improve overall thermal performance, maintain a continuous air and vapor barrier, and preserve the weather integrity of the system. One example of this technology can be found in our Formavue FV600 window, which integrates with our Formawall Dimension Series insulated metal panel. The window head incorporates a large thermal break in the aluminum extrusion close to the center of the insulated glass unit. In addition, foam is factory installed in the extruded window frame, improving thermal performance. The window frame has joinery similar to the standard, panel-to-panel joinery of Formawall Dimension Series, so the air barrier and vapor barrier are connected continuously between the panel and window. Details can make or break the aesthetics, efficiency, or performance of a product or project. At CENTRIA we surround ourselves with engineers, architects, building scientists, and detailers that understand how to develop details that work. As you can see, at CENTRIA, we sweat the details. Metalmag | Summer 2015 13 PROJECT PROFILE life is Advanced water treatment plant gives water a public face with a modern design aesthetic. BY HENRY BURKE SECO Architectural Systems was an integral part of the build team behind the United Therapeutics facility in Research Triangle, N.C. 14 Spring 2015 | Metalmag “Water is life.” The proud slogan of DC Water, the District of Columbia Water and Sewage Facility, may seem fairly obvious at first. Everyone knows that water is a vital resource, but few take the time to appreciate just what that means. On a micro level, each of us needs clean, fresh water to survive. On a macro level, the delivery of clean water and evacuation and treatment of dirty water is one of the most important features of human society. In spite of its importance, water is a very easy thing to take for granted. When the tap is turned on, we expect water to come out. But as recent drought conditions in California have so clearly highlighted, water management isn’t simple. As populations grow and water resources become increasingly stretched, major metropolitan areas rely on complex systems to ensure safe water and sanitation for their citizens. Wastewater treatment plants are a big part of those strategies. In the nation’s capital, DC Water shoulders a big part of that water management strategy. It receives and treats wastewater collected from the Washington, D.C., sewer system, as well as from the Maryland and Virginia suburbs. More than 330 million gallons of raw sewage flow into DC Water’s Blue Plains Advanced Wastewater Treatment Plant from area jurisdictions each day. The plant discharges to the Potomac estuary, and DC Water is required to meet some of the most stringent National Pollutant Discharge Elimination System standards in the country. “The Blue Plains Advanced Wastewater Treatment Plant covers 150 acres on the bank of the Potomac River on the southernmost tip of the District of Columbia,” says Randy A. Morrison, project manager with Fairfax, Virginia–based Samaha, the design firm tasked with giving a facelift to the DC Water treatment plant. “This project was deemed a ‘gateway’ project by D.C. regulatory agencies due to its high visibility upon entry to the nation’s capital. Samaha worked closely with the U.S. Commission of Fine Arts and the D.C. Office of Planning during the design process.” There has been a smooth working relationship between Samaha and DC Water for quite some time, and that familiarity came through in this very collaborative project. “Samaha has been providing DC Water with architectural design services for more than ten years, at Blue Plains and other DC Water sites around the District,” Morrison says. While the facility’s main role is a very functional one and its primary focus is treating the District’s wastewater, Samaha was brought on to explore another dimension of the building’s expression. It needed to interact with the Metalmag | Summer 2015 15 community to better inform and educate local residents about the importance of the work that is done there. “One primary goal of the project was to represent the face of DC Water and Blue Plains to the public,” Morrison says. “The building serves as the primary entry point for all visitors to the plant. The visitor center includes interpretive exhibits that educate the public about water treatment and DC Water’s role as a steward of natural resources.” To help attract positive attention to the facility and public interest in what the organization does, the building needed to look the part. The building needed to reflect the aspirational spirit of DC Water, and metal helped achieve the desired look. The project utilized CENTRIA Formawall® Dimension Series® insulated core metal wall panels and Profile Series Exposed Fastener Profiles BR5-36. Custom colors were used on both products. “The custom color panels that CENTRIA was able to provide enabled the architecture to incorporate DC Water’s official branding color scheme,” Morrison explains. “The metal panels also provide a sleek, modern design aesthetic that contrasts successfully with the brick patterns we borrowed from some of the historic Art Deco buildings on the site. DC Water wanted this building to project an eye to the future with a nod to the past.” The Advanced Manufacturing Research Centre University of Sheffield , England | Bond Bryan Architects Blue Plains Advanced Wastewater Treatment Plant DC Water, Washington, D.C.

The highly recycled and recyclable nature of metal is part of the eco-friendly statement made by the building. “DC Water wanted this building to illustrate sustainability through architectural example,” Morrison explains. “The project incorporates a vegetated roof, solar panels, and other green design features.” One of the largest, most advanced wastewater treatment facilities in the world, the Blue Plains Advanced Wastewater Treatment Plant is a point of pride for the District. The design team is pleased that it has been so well received in the community. “We have received nothing but positive feedback on this project,” Morrison says. ® TM Wall + Window Wall Systems | Skyroof + Skylight Systems | Canopies + Walkways | Clearspan Systems Produce: soft, glare-free, diffused natural daylighting with superior thermal performance Promote: healthier, more comfortable and productive environments where people can excel Protect: by offering visual privacy to occupants and vandal, graffiti + high impact options Provide: durable, low maintenance construction that translates to lower life cycle costs Predict: proper lighting designs utilizing our complimentary daylight modeling services KALWALL ® For more information contact us at 16 Summer 2015 | Metalmag KALWALL.COM | 800 258 9777 high performance translucent building systems New Orleans East Hospital New Orleans, LA Eskew+Dumez+Ripple THE RIGHT FIT Building retrofits present a unique set of challenges, and no two projects are the same.
