How Metal is Shaping Resilient Building Design in a Climate of Crisis

By Fiona Maguire-O’Shea, METALCON staff writer

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.”

New Study Verifies Steel Roofs Can Last As Long As The Buildings They Cover: Typically 60 Years Or More.

Low-Slope-Galvalume Roof

By: John Ryan, Metal Construction Association

The cost of replacing a roof can be one of the most significant maintenance expenses in the life of a building. USGBC’s Leadership in Energy and Environmental Design building rating program (version 4) assumes a building service life of 60 years. With most types of roofing, building owners can expect to replace the roof once or twice in that amount of time, incurring significant expense to do so.

Many buildings are The Metal Construction Association (MCA) is proud to announce a new study that verifies that coated steel roofs can last as long as the buildings they cover. The research study concluded that the expected service life of an unpainted 55% Al-Zn coated steel standing seam roof constructed today in a wide range of environments using best practices can be expected to be in excess of 60 years.

AIA Economist Bullish on Nonresidential Construction Activity

By: Jane Martinsons, Metal Construction Association

Kermit Baker, AIAKermit Baker, chief economist for the American Institute of Architects in Washington, DC, told attendees at the recent MCA Annual Meeting in Clearwater Beach, FL, that although nonresidential construction has been slow to recover from a steep downturn in 2013, several emerging signs point to increased activity throughout 2014.

As a guest speaker at the January meeting, Baker noted several leading economic indicators that point to an improving economy, including that housing starts have accelerated in recent months and that house prices, which continue to recover, have gained back more than 40% of their losses. He also said that net household growth has been dominated by renters in recent years, pushing down the rate of ownership.

“The housing recovery is well underway, but production levels are still below long-term potential,” Baker said, adding that a rate of 1.6–1.8 million housing starts per year is still years away.

Despite the positive market fundamentals, there have been modest gains in spending on nonresidential buildings, Baker said. He noted that the nonresidential construction sector faces several challenges and opportunities, including that recovery to date remains modest, with little improvement over past year; commercial property values are recovering “nicely”; and real estate market fundamentals, such as vacancies and rents, remain positive for most commercial market segments.

Meanwhile, architecture billings point to emerging upturn in nonresidential building activity. “Even with slowdown toward the end of last year architecture billings are in the midst of an upturn, with the strongest growth since the recession began,” Baker said.

Baker added that construction spending should see solid single-digit growth in 2014, with recovery continuing into 2015.

Plans for the MCA Summer Meeting, set for June 23–25 at the Westin O’Hare in Rosemont, IL, are underway. Online hotel reservations and a preliminary program schedule are now available. For more information, visit the Events page on the MCA website.

New Environmental Product Declaration for IMPs

By: Jane Martinsons, Metal Construction Association

An Environmental Product Declaration (EPD) for insulated metal panels (IMPs) is now available from MCA.

EPDs provide life-cycle assessment information and details about the product’s environmental impact (i.e., raw-material extraction, transportation, packaging, and disposal).  As such, EPDs assist purchasers and users in making informed comparisons among products.

“With the recent approval of LEED v4 rating system, we expect to see more members of the design community looking for EPDs as part of an overall emphasis on transparency,” notes MCA Technical Director Scott Kriner.  “The EPD for IMPs is based on the life-cycle assessment of this product category. It is a major step forward for the metal construction industry in reporting the environmental impact of IMPs.”

IMPs are composed  of rigid foam that is sandwiched between two sheets of coated metal. Their steel or aluminum panel facings create a vapor, air, and moisture barrier that provide long-term thermal stability. According to MCA-member manufacturers, IMPs

  • offer long-term durability
  • come in a multitude of colors and finishes
  • offer cost-competitive construction advantages and long-term high performance to help lower operating costs for building owners in any construction market.

Metal Construction in Atlanta: Portman Family Middle School

Portman Family Middle School, Atlanta, GA

Editor’s Note: As we gear up for METALCON International, Oct 1-3 in Atlanta, we’re highlighting some of our favorite Atlanta metal construction projects. We hope to see you next week in Atlanta!

Sports arenas, event centers and skyscrapers generate the most buzz around their construction. Other buildings, such as schools, may not enjoy the limelight, but they’re no less important. In fact, one could argue the design, planning and function of a school building affects the future of more people than any other building type.

As you tour Atlanta during the upcoming METALCON, Oct 1-3, you can’t miss metal’s contributions to the city’s famous buildings. But get off the beaten path a bit, and take note of some of the less known, yet highly influential ones.

Atlanta-based Portman Family Middle School is a prime example of design done well, and metal products contribute to the middle school’s educational and green attributes. A LEED Gold-certified building, construction of the middle school was made possible by a generous $10 million donation by Jan and John Portman.

Designed by architecture firm Shepley Bulfinch, the 75,000 sq.-ft. building was completed in 2009. Some of the “green” features of the design include:

• a garden roof used as an interactive learning space with native plants fed by a rainwater-fed runnel carrying water through the garden to a cistern below
• low-flow faucets, waterless urinals, and dual flush toilets
• daylight sensors, solar hot water, and a high-performance exterior envelope

ALPOLIC aluminum composite panels are central to the high-performance exterior envelope. The metal panels were chosen for their versatility, durability, modern appearance and energy efficiency.

As an energy-efficient green building, the middle school not only saves tens of thousands of dollars annually, it also educates hundreds of children about the importance of sustainable living.

Metal’s use as a green construction material will no doubt be a hot topic at METALCON this year. For a prime example of metal’s green attributes in action, check out Portman Family Middle School, too.

The Mighty Georgia Dome–Only Steps Away from METALCON

Georgia Dome, Atlanta, GA; Centria

Step outside the Georgia World Congress Center when you attend METALCON International in Atlanta next month, and you can’t miss noticing a prime example of metal’s strength and beauty in building design.

Located across the park plaza from the convention center, the Georgia Dome stands mighty as the largest cable-supported domed stadium in the world. The 290-ft.-high roof is composed of 130 Teflon-coated fiberglass panels covering 8.6 acres. The roof’s supporting cable totals 11.1 miles, and the Dome is as tall as a 27-story building, according to the Georgia Dome website.

Of note to MCA members, the Georgia Dome features CENTRIA’s Formawall Dimension Series and Profile Series Exposed Fastener Panels.

Opened in 1992, the Georgia Dome took center stage at the 1996 Olympic games as the setting for gymnastics and basketball events. Home to the NFL’s Atlanta Falcons and Georgia State Panthers football teams, the Georgia Dome also recently hosted the NCAA Men’s Final Four basketball tournament in April this year.

METALCON will be take place Oct. 1-3. For a look at the Georgia Dome in action, book your METALCON travel to Atlanta a few days early. The Falcons play the New England Patriots September 29th in this awe-inspiring stadium. The Dome also offers individual and group tours if you don’t have time for a game.

Arced and Ready for Football

The John & Mary Brock Football Facility, Georgia Institute of Technology, Atlanta, GA

By:  Jane Martinsons, Metal Construction Association

Although the credit of Georgia Tech’s 63-21 win over Western Carolina last weekend belongs to the team and coaches of the Atlanta-based institute, maybe, just maybe, metal roofing played a role in the win? Okay it’s a stretch, but consider this: Georgia Tech players began practicing in the school’s new indoor practice facility in August, and that facility has a metal roof that is designed to arc like a perfectly thrown pass and provide maximum space inside. If the roof “played a role in a winning football formula,” says Bill Croucher, director of engineering at Lancaster-PA-based Fabral, then “Fabral is happy to be part of it.”

It sounds like a win-win to us.

Croucher says that metal is a top choice for curved roofs on stadiums and practice facilities because it provides a choice of color, profiles, and paint and substrates; has a high-recycled content; and is 100% recyclable when the useful life of the roof is over. Moreover, Fabral’s structural standing-seam metal roof offers superior wind-uplift resistance and is Class A fire rated.

Joseph A. Knight, AIA, Knight Architects, Inc., Atlanta, points out that the metal roof panels stretch the full width of the 80,000-square-foot building, without any end-seams. The 24-gauge Galvalume panels are 245-feet long and 16-inches wide. “The metal shines and contrasts nicely with the adjacent brick buildings, as well as the brick at the base of the practice facility itself,” Knight says. “There is really no other material we could have used that would have presented such an aesthetically and economically strong solution.”

Know What to Look for When Inspecting MCM Panels

MCM PanelBy: Jane Martinsons, Metal Construction Association

Wondering about a possible defect in the Metal Composite Material (MCM) panels you’re installing, such as a deflection or bow, a surface imperfection, or a problem with the finish or color? While these instances may be rare, a new white paper by the Metal Construction Association  (MCA), available at no charge, can help you determine whether a MCM panel or system is not meeting current code and industry standards.

It’s vital that installers, architects and designers know acceptance criteria for painted metal surfaces. However, “questions concerning visual appearance often arise during the architectural walk-through on a project,” says Andy Williams, MCA’s director of codes and standards. “This white paper highlights many real-life situations so that architects and designers can understand what to expect. More knowledge at the beginning of a project prevents problems from developing later in the process.”

MCA brings together a diverse industry for the purpose of expanding the use of metal in construction through marketing, research, and technology and education. Please join us at MCA’s 2014 Annual Meeting on January 26–28, 2014, at the Sandpearl Resort in Clearwater Beach, FL.  For more information on the conference and the 3-page white paper, Visual Acceptance Parameters for Metal Composite Material (MCM) Panels and Panel Systems, visit www.metalconstruction.org.

Metal Construction in Denver: Sports Authority Field at Mile High Stadium

Sports Authority FieldBy: John Ryan, Metal Construction Association

We promised to share some of our favorite examples of metal construction in Denver as we get closer to the AIA National Convention from June 20-22 at the Colorado Convention Center. Here’s our first:

Sports Authority Field at Mile High Stadium

Sports Authority Field at Mile High Stadium opened in September, 2001, and features insulated metal panels (IMP) from Centria, as well as Reynobond aluminum metal composite material panels (MCM) from Alcoa.

Best known as the home of the NFL’s Denver Broncos, Mile High Stadium has been home to the likes of Peyton Manning and Tim Tebow. The metal stadium also was the venue for the 2008 Democratic National Convention, as well as concerts from bands including U2 and the Eagles.

Formerly known as Invesco Field at Mile High Stadium, Sports Authority signed a 25-year agreement for the naming rights in 2011. That should be a safe investment because the metal wall panels on that stadium will be looking great and performing well for many years to come.
