According to the article, if the trend continues, architecture firms will need to hire new design teams—welcome news for working architects, whose numbers declined to 153,000 in 2011 from 214,000 in 2007. “Rising billings also are viewed as a gauge of future construction activity because real-estate developers tend to break ground on new projects 9–12 months after they hire design firms,” it reads. And with that, 2013 is looking promising for metal construction as well.
More often than not, architects and designers choose Insulated Metal Panels (IMPs) for a combination of reasons, not the least of which is aesthetics given that they come in a variety of styles, sizes, colors, finishes, and textures and can be installed both horizontally and vertically. Metl-Span’s Tuff Wall® IMPs, for example, provide a stucco-like appearance to the new corporate-headquarter addition to the Hitchiner Manufacturing facility, Milford, NH, a casting supplier to manufacturers in the aerospace gas turbine engine industry. But according to Dennis Mires, PA, of The Architects in Manchester, NH, IMPs also met insurance requirements, stayed within the owner’s budget, and provided a high-tech look for the company.
With that in mind, what are top reasons for choosing IMPs? Industry experts say that the metal panels:
are energy-efficient. IMPs have two metal skins, an interior and an exterior, which are bonded to a foam polyisocyanurate insulation core, making them highly energy efficient, said Brian Jaks of Green Span Profiles, Waller, TX, a manufacturer of IMPs. Initially used on cold-storage facilities, the panels have R values as high as 8 per inch, compared to 3.7–4.3 per inch for batt insulation, and range in thickness from 2–6 inches.
have thermal performance. According to Ken Buchinger of Metal Building Components, Inc., who recently spoke at METALCON, IMPs provide continuous insulation and consistent R values across walls, and have concealed fastener systems that prevent thermal bridging between the exterior and interior skins. He further noted that IMPs tend to hold their R value over time and do not have significant thermal drift.
allow for fast installation. IMPs’ one-piece construction makes for faster installation, Buchinger said. Faster installation helps lower construction costs and interim financing costs. Moreover, he said, the steel skins are resistant to abuse and, compared to conventional building envelope materials, are not as affected by adverse weather conditions such as high winds.
are suitable for green building. IMPs were used on the new LEED-gold-certified “Bartholomew Building” addition to William Allen High School in Allentown, PA, for their simplicity of design. “The [system] just goes together,” said Mitch Miller, associate and director of specifications of USA Architects, Easton, PA. “You’re installing the insulation and the finished panel at the same time.” Furthermore, the metal in a panel’s skin often has a high content of recycled steel or aluminum, and, when IMPs are removed from a wall, they can be recycled or re-used on another project, saving them from the landfill.
offer unsurpassed design flexibility. “People like the panel because it has a flat appearance,” Jaks said. “It doesn’t necessarily have corrugation and architects like that.” He added that IMPs are available in a variety of textures, including smooth, embossed, and heavy embossed. They also come in wide range of colors, and can be customized to match any color palette. IMPs’ design flexibility allows the ability to achieve almost any look and increase curb appeal.
are well suited for roof applications. More than 130,000 sq. ft. of IMPs was used to reroof the eight-building Haughton Middle School complex in Haughton, LA. According to Lauren Marchive, project architect with Newman Marchive Carlisle, Inc., Shreveport, LA, the local school board chose IMPs for their thermal performance and because the roof system was available in red, which matched the school’s original design. Even more vital was the speed and ease of installation, and that the roof could be installed during the school year on sections of buildings that were not in use.
Choosing between metal construction materials and systems can be complex—each project has a number of factors that need to be considered. But IMPs offer a host of benefits to make them an attractive choice for a wide variety of projects.
Today, it doesn’t make any difference whether you’re planning to build or remodel a tall skyscraper in Manhattan or a rustic vacation getaway outside of Albuquerque, the stakes are high when it comes to product selection.
The first step to specifying products that will lead to a successful project is to determine your criteria. What are the key things you’d like to achieve? Once you determine your criteria, you have benchmarks to weigh competing products against and determine what it will take to create the building of your dreams.
In determining your criteria, there are several keys areas to consider. Let’s take a look at them.
