At the new 30-story McMaster Graduate Residence Tower in Hamilton, Ontario, Diamond Schmitt architects crafted 550 single-skin metal wall panels to create a dynamic aesthetic and revitalize the downtown core.
Inspired by the chevron floor plate façade design on the neighboring Hamilton City Hall, the angular, dimensional cladding begins at the podium level and extends vertically across all façades.
Winning a MCA 2025 Design Award in the Single-Skin Metal Wall Panel category, Judge Kevin Wagner, AIA, associate principal at Substance Architecture in Des Moines, remarked, “The folds of the metal, it’s really captivating—just thinking about what it took to fabricate because every piece is custom. It’s this totally unique, sculptural piece of art.”
“The closer you get, the more refined it gets,” observed Judge Rick Schneider, FAIA LEED, founder, ISTUDIO Architects, Washington, D.C. “There’s one gesture repeated at different scales in different materials.”
“Some of the paneling is perforated, so it’s even more intricate,” added Judge Dan Rodriguez, principal founder at Rodriguez Romero Design and Architecture in Los Angeles. “You almost couldn’t use any other cladding because of how intricate it was.”
To achieve the architect’s vision for the metal façade, PPG Duranar Sunstorm Aluminum Plate panels were selected. For fabricator Sobotec, the aluminum panels were an ideal material to create the varying geometric shapes comprising the modern, finned design. The fabricated panels can also be individually removed and repaired on a panel-by-panel basis, allowing any scrapes or dings to easily be fixed in the long term.
Duranar Sunstorm is a mica-effect, two-coat system which adds pearlescent mica flake to the color layer to create a metalescent look. The long-lasting, weather-resistant, aesthetic finish is achieved without aluminum flake or a third clear coat layer.
The angled panels, perforated metal and curtain wall — combined with an expansive public plaza — engage the surrounding community. A rooftop terrace with panoramic urban views, an integrated cycling path system and convenient access to public transit further enhance the student experience. Building amenities include a fitness center, outdoor rooftop running track, movie room, study spaces, music room, games room and a rooftop BBQ area.
The building is tracking LEED Gold and features a high-performance building envelope and operable windows for individualized comfort. The extensive green roof offset stormwater, reduces the heat island effect and supports biodiversity.
The high-rise houses 600 graduate students and their families and contributes to a vibrant, inclusive campus culture that enriches community life.
In sum, Wagner concluded, “The McMaster University tower is above and beyond. It deserves all the recognition.”
La Nube, meaning ‘the cloud’ in Spanish, is an innovative STEAM discovery center located in downtown El Paso, Texas. It offers visitors of all ages the chance to explore, play, create, and challenge the limits of innovation. True to its name, La Nube is a place where imaginations can reach as high as the clouds. The building is a 2025 MCA Design Award winner.
The building’s distinctive geometries make it stand out in the city’s skyline: the rectilinear base, encased in glass, offers interior views that attract passersby to enter the public lobby. Above, a series of rippling barrel vaults rise gracefully, culminating in a crown that resembles clouds.
To bring this creative vision to life, the design team used metal wall systems to shape the building’s “cloud-like” form. They employed modular aluminum wall panels—finished in Ascot White, Bone White, and a custom white—in different widths and lengths to create a bold, patterned façade. Arranged vertically, these panels form a flowing, cloud-inspired appearance that changes with light and perspective, reinforcing the building’s symbolic link to endless imagination.
The steel roof panels incorporate recycled materials and are entirely recyclable after their long lifespan. Moreover, the Titanium 70% PVDF roof color has an SRI (Solar Reflectance Index) of 68.60, reflecting sunlight, which reduces heat transfer into the building and decreases the need for air conditioning in hot environments. This also contributes to lowering the building’s operational carbon emissions.
The façade design surpasses simple aesthetics. Floor-to-ceiling windows are embedded in patterned panels, illuminated by the vibrant glow of the interactive exhibits within. Between the wall panels, subtle lighting elements create the illusion of a floating cloud, with small points of light resembling stars at night. These creative details demonstrate how modular wall systems can function both as structural components and as artistic features.
“The broad choice of ATAS modular wall and roof systems provided the design team with the flexibility to turn their vision into reality,” said Steve Minunni, Director of Modular Wall Systems at ATAS. “The wide range of profiles, colors, and support from a single source allowed the project to balance creativity and practicality.”
Now celebrating its first anniversary, La Nube joyfully continues to embody innovation and inclusivity in El Paso. It serves as a wonderful example of how carefully designed wall systems can transform a simple idea into a meaningful architectural and cultural icon.
Metal walls are increasingly being used in single-family and multi-family residential projects. Metal is a wall material of choice due to its resiliency to weather and fire, low maintenance, speed of build, and sustainability.

As wildfires rage across the American West, hurricanes intensify in the Southeast, and insurance markets tighten nationwide, the demand for fire-resilient, climate-ready buildings is no longer theoretical—it’s urgent. What was once seen as rare or exceptional is now becoming the new norm, both in the U.S. and globally. In the metal construction sector, leaders are taking note and taking action.

In a recent METALCON Online webinar, a high-caliber panel of experts came together to unpack the intersection of building science, climate policy, material innovation and insurance economics.
With METALCON 2025 on the horizon, the session was moderated by Frank A. Stasiowski, FAIA, CEO and founder of METALCON and PSMJ Resources. He was joined by Alan Scott, FAIA, director of sustainability at Intertek; Dick Davis, former fire engineer and technical specialist with FM Global; Brian Partyka, vice president of business development of Carlisle Companies; and Anoush Brangaccio, senior policy advisor at the Florida Office of Insurance Regulation.
From testing standards and code lag to community planning and insurance incentives, the discussion emphasized one central theme: metal has an integral role to play in the future of resilient construction.

Codes Are Catching Up—Too Slowly
Recent catastrophic fires and storms have revealed painful shortcomings in how the construction industry approaches resilience. Many buildings, especially older ones, were not designed to withstand the hazards resulting from today’s extreme climate events. While building codes are evolving, our panelists were unanimous in one critical point: they’re not keeping pace with the climate.
“The fact that there has been such disaster, it shows you cannot rely on the existing codes and standards,” said Dick Davis. “We have to look closely at the science and figure out what materials to use whether it is residential, commercial or industrial construction.”
Alan Scott added, “Recognize these hazardous events can happen anywhere. What happened in the past is not necessarily indicative of what will happen in future occurrences, so assessment is required.” Scott shared a sobering example of a California apartment building that highlighted the flaws in current fire risk mapping. Depending on which map you used, the building was shown in both a low-risk and high-risk zone—yet it ultimately burned to the ground in the recent wildfires. “Perhaps some preassessment to determine risks might have prompted some action to reduce those before hazard happened.”

Anoush Brangaccio explained the structural delays in the code-update process. “The building code is updated every three years,” she said, adding that some states lag even further. Not all states have uniform building codes, and if they don’t, it’s time they consider implementing one.
Davis confirmed that reality: “I’ve seen situations where some states were still using the 2003 code when the 2015 code came out. That’s how backlogged it can get. And people need to remember that code requirements are minimum requirements. There’s nothing wrong with exceeding those requirements.”
Climate Is the Driver—and It’s Changing the Game
“I would just add that climate change is really the key driver behind most of these tragedies,” said Brian Partyka, “including stronger storms, heavier rainfall, more intense winds, and worsening droughts in California.”
Frank Stasiowski asked whether these events are catalyzing innovation or constraining it. “It spawns innovation,” Partyka responded. “We’ve stopped talking about a metal roof and [started saying], ‘Let’s talk about a fire-resistant underlayment product with a two-hour burn rate.’”
Partyka pointed to multiple product innovations in development: “We have a two-hour fire-rated wall insulation product that’s made of denim jeans, old, recycled denim jeans. It’s pretty awesome to watch the innovation that happens as a result.”
Metal’s Edge in a Hazard-Rich World
While no single material can solve every risk, metal stands out as one of the most effective front-line defenses—especially in fire-prone regions.
“Metal roofing would be a wonderful solution for areas that are prone to fire, wind and hail,” said Partyka. “Will they dent in hail? For sure, they’ll dent in hail…but the metal roof is going to have a Class A fire rating.”
He noted that organizations like the Insurance Institute for Business & Home Safety (IBHS) are pushing for more rigorous standards. “There’s a wildfire prepared neighborhood program by IBHS… and metal roofs are mentioned in that as a non-combustible Class A fire rated [product].”
But Partyka was careful not to oversell. “It’s not the end-all be-all…I don’t want to say this is the cure, and everybody should have a metal roof. I think it will help to eliminate some of the possibilities of ignition.”
Davis explained why not all metals perform equally in fire scenarios: “The melting temperature of aluminum is about 900 to 1,200 degrees Fahrenheit; copper is approximately 2,000 degrees; and steel is north at 2,600 degrees. Actual flame temperatures vary from 1,000 to 2,000 degrees.”
Testing, Certification, and Insurance: The Approval Matrix
“I think one of the successes in Florida has been their Florida Product Approvals system,” said Partyka. “You don’t have that code approval or that number, then guess what? You’re not going to be able to sell your products in the state of Florida.”
Davis emphasized the importance of rigorous testing. “There is a requirement pretty much everywhere for testing exterior exposure, fire exposure roof covers…that test is ASTM E108 or UL790.” He warned that not all materials are held to the same standard: “Codes have more or less grandfathered or waived the tests for certain types of materials…but aluminum is not grandfathered.”
Scott added, “Generally, architects aren’t aware enough about resilience issues…there needs to be greater awareness among the design community about all the different standards and tests.”
From the insurance side, Brangaccio detailed how Florida incentivizes high-performance materials: “We do offer discounts…relating to the roof, roof coverings, connections.” She added, “We’ve even broken out metal roofs, and…metal roofs compared to some of the other roofs would get a higher credit for wind.”
Holistic Design and System Thinking
The consensus was clear: resilience isn’t about one product, one material or one code update—it’s about the system.
“Whether we’re talking about fire resistance or hurricanes or floods,” said Scott, “designing buildings that have overall greater sustainability like designing for passive house type standards…means you’re both resilient against those hazard events and…have a building that’s less expensive to operate, uses lower utilities and has a lower carbon emission.”
Davis drove the point home with a stark reminder: “If that fire gets inside the building, no matter how it gets in there, you could destroy the whole building.” He emphasized the need to consider the entire building envelope to protect the structure from wildfire exposure—the roof, the walls, the window systems, soffits, and even vent mesh. He commented that people often overlook the importance of the windows and should use fire-rated glass, which includes heat-blocking gel layers, or double-pane tempered glass, which withstands high heat better than standard glass. “Think of the window as a system, it’s got a window frame.” Steel is ideal, while vinyl should be avoided unless reinforced with steel due to its low melting point.
Global Perspectives, Local Urgency – How does the U.S. compare globally?
“I think that we’re ahead of most of the rest of the world regarding wind design,” said Davis, referencing his work with international clients during his time at FM Global. But in terms of fire design, “They use a lot of mineral wool insulation in Asia, which is good. It’s a better fire performer than a lot of the other insulations on the market.”
Still, differences in testing standards—ASTM in the U.S. vs. ISO elsewhere—pose challenges. “We don’t always agree on what’s the best test,” he admitted.
Where to Go from Here—and METALCON’s Role
As disasters evolve, who’s responsible for keeping the industry ahead?
“I don’t like to put too much reliance on waiting for the codes to change to solve all the problems,” said Davis. “If a celebrity in Southern California wants to build a $5, 10, $20 million house, I would tell him to first engage a fire protection engineer and a structural engineer to give him some guidance. If he’s going to spend that kind of money on a house, build something that’s actually going to last.”
Scott suggested a multi-layered approach: “It’s state and local policy and codes. It’s urban and regional planning and zoning… all of those layers have to fit together to create the complete package of resilience.”
Anoush Brangaccio added, “If we’re going to ask our consumers and our residents to do this, they need to get something back to help offset it.”
That’s where METALCON, the only global event dedicated to the application of metal in construction and design, comes in.
“We at METALCON have a role in this—and our role is to keep this communication going,” said moderator Frank Stasiowski in closing. “We need to make sure that the innovation happening in labs and factories is matched by awareness in the field—and that’s a communication challenge we’re ready to take on.”

Helping to bring architect Snøhetta and artist Jose Parlá’s vision to life for the expanded 18,000 square-foot Far Rockaway Library, prismatic metal composite panels in the shape of trapezoids decorate the library’s interior and exterior in Queens.
Prismatic Series ALPOLIC MCM panels wrap around the building’s corners and compliment a large A-shaped mural crafted by Parlá. The artist’s mural was digitized and encased in colored glass, presenting a “Style Writing” half architecture, half canvas facade. Parlá selected hues of yellow and orange to best represent the colors of sunrise off the Long Island coast.
Snøhetta specified the MCM panels in MRT Prismatic Red and SAW White finishes. The mica flakes in the prismatic panels present shifting colors depending on the time of day and the angle of viewing. The panels gel with the artwork on the mural, adding depth and texture to the exterior and mirror the mural’s dynamic nature. MCM was also installed on the baffle ceiling over the atrium.
The orange metal fins over the concrete staircase energize the space with a strong pop of color and blends with the yellow orange glazing and dichroic glass on the second floor perimeter which shifts the filtering sunlight into a cascade of colors. This second floor location also features an art installation titled “Feynman diagrams” written in a code based on the work of Far Rockaway-born physicist Richard Feynman.
Inverted pyramidal columns create an intriguing interior and help enhance daylighting bounced into the space.
In all, more than 10,000 square feet of 6mm fire-resistant Prismatic MCM were applied on the exterior and interior, and 2,500 square feet of the high gloss 6mm SAW White was designed for the interior walls, a portion of which is found behind the information desk.
The installation of glass and MCM required careful planning and execution to ensure that the panels fit perfectly, particularly at the building’s diagonally oriented corners.
“The diagonal, that was a bit of a challenge itself. To get everything perfect from the form to frame that so those corners worked – everything had to be perfectly plumb,” related Fred Slade, senior project manager, EDA Contractors, Bensalem, Penn.
To meet the unique requirements of the project, the design team had to select lightweight, workable materials to craft the various geometric spaces of the design. These requirements directed the team toward MCM as the optimal material for successfully bringing their design to life.
For example, the fabrication of the metal ceiling baffles was created in three large segments inside EDA’s shop and involved folding the MCM like origami.
“I remember thinking they look like a lunar module, and marveling at how these were going to be hung in the air,” recalls Slade.
Making this portion of the project even more complicated, the team worked hard to marry the drawings for the glass skylight, concrete ceiling and MCM baffles to create smooth transitions and a tight enclosure. This included pulling in actual field dimensions for the exact location of the metal panels.
The noteworthy LEED Gold project picked up a few awards including the Municipal Art Society of New York’s 2024 MASterworks Awards as Best New Building, an American Institute of Architects (AIA) NY Design Award Citation in Architecture, an Urban Land Institute Finalist citation for Excellence in Institutional Development and an Architect’s Newspaper Best of Design Award for Libraries.
