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.”

WHAT’S HOT FROM THE SUMMER MEETING: International Zinc Association Advocacy Effort

MCA is part of a Zinc Coalition that was formed by IZA in the aftermath of the Washington Department of Ecology rainwater runoff project that was concluded in 2014. Misuse of the information related to zinc from the runoff report is influencing the Governor’s office and the legislative bodies.

Letter-writing advocacy, with guidance from IZA, is showing positive impacts. Several meetings have been scheduled with IZA and Coalition members to discuss the shortcomings in the runoff report and the outdated clean water regulations. MCA members that have facilities in Washington were asked to get involved in the effort. Similar issues are being seen in California, the Great Lakes region and in Canada.

WHAT’S HOT FROM THE SUMMER MEETING: Air Permeability

MCA is conducting research at the University of Florida to evaluate the performance of discontinuous metal panels, such as modular metal panels and snap-together standing seam.  From that evaluation we will be investigating how to characterize the air permeability of these types of roof panels in order to develop a new test method to more realistically reflect the wind uplift that these systems can withstand.  The main test to be utilized for the work is the UL 1897 in static and dynamic mode.  Wind tunnel testing and variations to existing industry test methods will be used.  An industry Advisory Panel has been created and a literature search has been summarized.  Recently the Experimental Research Plan was shared with the Advisory Panel for their input.  Test materials are being collected and shipped to the University of Florida for testing to commence in July.  This is a significant research project, and is being conducted over three calendar years.

A look at, and beyond, HPDs

By: Jane Martinsons, Metal Construction Association

Jim HoffIn a recent webinar, Dr. Jim Hoff of the Center for Environmental Innovation in Roofing noted several benefits and limitations of the Health Product Declaration (HPD), and even looked beyond it to newer alternative documents.

Hoff said that on the upside, the HPD document itself is relatively simple and straightforward— “it looks like a Material Safety Data Sheet (SDS),” —and is inexpensive, especially compared to Environmental Product Declarations. Still, he noted the HPD

  • uses little or no formal consensus review. “As a building envelope researcher and a longtime participant in standards processes throughout the world, I believe it certainly is a limitation to have a development process that is an ad-hoc process, developed outside a recognized consensus standard,” he said. “The development process does not include all stakeholders that are typically included in ANSI and ASTM processes. For example, building material manufacturers are not included in specific decision-making committees,” he said.
  • identifies hazard without assessing risk.
  • identifies chemicals of concern using many different sources with varying thresholds. Hoff cited examples of hazard warnings, such as the U.S Environmental Protection Agency’s (EPA) list of known or likely carcinogen, but also pointed to what he considers “less authoritative” warnings. For example, “California Proposition 65 includes many chemicals hazardous only as precursors or during manufacturing,” he said.  “When you’re looking at materials that are key ingredients in many common roofing materials [i.e., titanium dioxide, carbon black, wood dust, and bitumen], they are not generally considered to be hazardous in their finished form.”

Other newer alternative documents may offer better information, he said. “There is a whole new generation of MSDSs that are starting in 2014 that are based on a very, very rigorous, globally harmonized system, now endorsed through international treaties and endorsed and integrated by  the U.S. EPA.” The new SDSs offer hazard information in a very similar methodology to HPDs and will be available much more rapidly, he said.

Another new product is the Product Transparency Declaration (PTD), which addresses risk as well as hazard assessment. “PTDs take a look at threshold levels and paths for exposure that are important in many products,” he said. Developed by the Resilient Floor Covering Institute and submitted  to become an ASTM standard, the PTD could be available to a wide variety of products, Hoff said.

Meanwhile, Hoff stressed that HPDs are included in LEED v4 and are likely to be proposed for next version of International Green Construction Code. As such, he calls on material suppliers to

  • be proactive and engaged.
  • develop a uniform approach and promote industry-wide initiatives to develop consistent reporting.
  • use the Notes section of HPDs to explain or tell the whole story of their products.
  • promote alternatives to HPDs that include risk assessment in addition to hazard identification.

How EPDs Will Impact the Building Envelope

MCA's Insulated Metal Panel EPD

By: Jane Martinsons, Metal Construction Association

Transparency is a common theme in design and construction these days, and product disclosure is quickly becoming a key issue for the building materials industry. Increasingly, Environmental Product Declarations (EPDs) are being required by designers and specifiers, and the findings of these reports are playing a more prominent role in how materials are chosen for projects.

Earlier this week, Dr. Jim Hoff of the Center for Environmental Innovation in Roofing discussed several tools for product disclosure, including EPDs, in a webinar featured by Architectural Roofing & Waterproofing magazine.

Speaking primarily to material manufacturers and building designers, Hoff noted that the concept of product disclosure is moving very rapidly into the construction marketplace and is being driven by several market forces, including the green-building press, green data aggregators, and by leading architecture-engineering firms that are participating in a disclosure campaign.

Product disclosure continues to emerge in building standards and codes as well, including LEED, ASHRAE 189.1, and the International Green Construction Code. “Although the concept of disclosure is relatively new, material disclosure has or will be adopted in every major green building standard and code, and it is being introduced at almost at an unprecedented pace,” he said. Hoff explained that EPDs help disclose well known environmental impacts (i.e., global warming and ozone depletion) using established metrics and standardized processes. “It’s a very quantifiable process based on good science,” he said. He further emphasized that EPDs use a well vetted, standardized format based on global ISO consensus standards and a scientific approach over the entire product life cycle. They also provide quantitative measures of key environmental impacts.

“Of course these benefits come at a certain price,” he said. “In fact, price itself is a primary limitation of EPDs today. In my consulting practice, I’ve been involved in the development of several Life Cycle Assessments and EPDs. The order of magnitude for a typical roofing material could easily be in the six figures by the time all is said and done.” He further noted that EPDs

  • are complicated.
  • pose difficulties in integrating products with varying service lives.
  • fail to address energy efficiency contributions. “When you’re looking at the environment impacts of thermal insulation or a cool roofing membrane, you [may] not be looking at environment contributions of those products, which could offset many of those impacts.”
  • fail to address health impacts. “EPDs today primarily address measurements of environment burden, but they do not specifically and are currently not designed to address the potential for health and safety burdens of materials.”

There are also challenges with limited underlying data, which may lead different practitioners to obtain different results.

Hoff encourages material suppliers to consider jointly developing generic EPDs for key industry product segments. “I think there’s a real value in that,” he said. “First, you’ll learn a lot more about the process yourself and, secondly, you’ll be able to provide much broader information that can be very helpful in the marketplace.” Then, he said, get the information to data integrators, but first make sure you are using the best information available.

The Metal Construction Association (MCA) recently compiled data from multiple manufacturers to publish an EPD for insulated metal panels (the full report and an executive summary are available on MCA’s website). MCA is putting the finishing touches on EPDs for single skin panels as well as metal composite panels.

Overall, “increased product transparency is good because it provides a better understanding of ingredients and supply chain impacts and a strong incentive for continuous improvement,” Hoff said. But, he adds, comparisons among products will remain difficult and unpredictable. Risks include overlooking important factors and trade-offs, and arbitrarily excluding excellent products and suppliers.

Hoff’s comments on Health Product Declarations will be featured in an upcoming blog. For questions on EPDs, contact Dr. Hoff at jhoff@roofingcenter.org.

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.
