Nothing But the Best for the Big Ten: Terra Cotta Rainscreen Wall System With Continuous Insulation on New Headquarters Provides Style and Performance

Posted By Nathan Pobre, Tuesday, February 19, 2019
Updated: Tuesday, February 19, 2019
Since its inception in 1895, the Big Ten Conference has pioneered standards of excellence for intercollegiate sports. It should be no surprise then that the design of its headquarters building in Rosemont, Illinois features the construction industry’s highest performing products. In the Midwest, where temperatures can swing 100 degrees between winter and summer, the effectiveness of a building’s envelope, in particular, is a major factor on interior comfort, energy efficiency, and building durability.

Echoing the red brick buildings on the college campuses the Big Ten represents, designers chose a terra cotta rainscreen wall system that creates a striking façade for the 50,000-square-foot building. The tiles themselves are 12 x 48-inch panels with a bright red-orange color and a smooth finish. Their distinctive color is created using a single-clay composition, but there is a range of natural variations that enhance visual interest. The panels weren’t chosen just for their looks though. Each piece incorporates self-supporting extruded clay cleats that eliminate the need for metal support clips during the installation process—reducing costs and install time.

The terra cotta tiles are only the most exterior of the layers that wrap the Big Ten headquarters’ building envelope. These layers, called an open-joint rainscreen system, allow pressure to be equalized in the space between two exterior wall components so weather elements don’t reach the inner wall (rainscreen), which contains the moisture barrier and other critical components. This makes the building mold and mildew resistant—a huge bonus in an area known for its summer humidity. The panels are attached to exterior cold-formed metal framing, which supports the rainscreen system to resist the wind and snow loads for the Chicago area.

Behind the framing is the workhorse of the wall assembly, a commercial-grade insulation from Portland, ME-based Hunter Panels. The continuous insulation system used was manufactured at the local Hunter plant in Chicago. Continuous insulation, as its name suggests, covers the entire wall surface, with the obvious exception of windows, doors, and fasteners, minimizing heat loss and thermal bridging that is inevitable in systems that only insulate between the studs. Hunter’s Polyiso foam-board insulation with foil facers on both sides offers R-values from 6.3 to 19.5 in a single layer—a marked improvement over other insulation options. Since the insulation panels incorporate the moisture barrier required to protect the building, they also eliminate a step from the installation process.

Even though the construction team was unfamiliar with some of the wall system’s elements before this job, they were able to quickly master the installation techniques. The entire exterior took only six months to install and the Big Ten will be reaping benefits of such a maintenance-free and energy-efficient system for decades to come.

Newest Shiloh House in Colorado Uses Polyiso Wall Boards for Superior Thermal and Weather Barrier

Posted By Administration, Thursday, February 7, 2019
Updated: Wednesday, February 6, 2019

When Colorado architects from the Davis Partnership were designing a new building for the non-profit Shiloh House, they were thrilled to find a product that would protect the building envelope from exposure to fire, water, and wind while integrating a continuous insulation system that would provide long-term thermal efficiency. The polyiso wall insulation solution from Rmax gave them flexibility to use a variety of external claddings for visual interest without compromising on protection from the elements and energy savings. Even better, with the help of Rmax’s in-house architect and field team, they were able to design a wall system with smooth, on-time installation that meet the rigorous NFPA 285 requirements.

Shiloh House has five locations across Colorado that offer nurturing, therapeutic and educational services aimed to help youth and families to overcome the impact of abuse, neglect and trauma. They helped over 1,000 youth last year alone.

This new facility in Centennial is situated on a 1.54-acre property and includes on-site parking, outdoor courtyards, and the spaces and amenities that support the group’s programming to promote family stability and help families achieve their goals, while ensuring continued access to community resources once Shiloh House services have been successfully completed.

For an organization with such lofty goals, every dollar saved in building operations is another resource that can be used to serve its mission. The Rmax polyiso wall boards provide continuous insulation—eliminating heat lost that could occur through the studs when insulating with traditional products that are installed only in the wall cavities—and have reinforced aluminum foil facers that offer enhanced durability, dimensional stability and greater radiant heat protection. They make it easier and less expensive to keep the building comfortable, no matter the weather conditions outside.

“When we’re designing a building, we try to meet the highest standards because we care about protecting the environment and saving our client money over the whole life of their building by maximizing energy efficiency,” the architects explained. “With a reliable weather barrier and superior insulative properties, the polyiso continuous insulation system really gives your building the best protection while actually saving time and hassle on installation since it includes multiple protective layers in a single product.”

And the finished product speaks for itself:

National Insulation Fly-In Day a Success

Posted By Nathan Pobre, Thursday, May 31, 2018

More than 130 insulation industry professionals recently gathered in Washington, DC for the second-annual Insulation Industry National Policy Forum. They met with 82 Congressional offices and Members of Congress – including Senator Rob Portman (Ohio) who has introduced a bill that would strengthen the nation’s commitment to energy efficiency – S. 385 The Energy Savings and Industrial Competitiveness Act. In addition, leaders from the Department of Energy, White House and U.S. Congress addressed the industry – including Representative Adam Kinzinger (IL), a leader on energy efficiency issues in Congress.  This year’s event included nearly 50 percent more attendees when compared to 2017 attendance numbers.

PIMA was a lead organizer of the fly-in event and some of the key points the association and it members made to lawmakers included:

  • The insulation industry employs more than 529,000 people and creates over $30 billion in annual payrolls.
  • The insulation manufacturing sector employs 37,000 Americans in 42 states with the largest number of manufacturing jobs located in Ohio.
  • Building energy codes – a driver for the use of insulation – are projected to save the US economy $126 billion in energy cost savings between 2010 and 2040.
  • Federal investments to resilient buildings provides a positive ROI for taxpayer dollars – a recent study demonstrates that exceeding the 2015 International Building Codes can save the nation $4 for every $1 spent. The insulation industry produces technology that contributes toward the value of these mitigation efforts.

The fly-in, and events like it, provide opportunities to ensure elected officials hear from and understand the importance of both the roofing and insulation industries to the overall U.S. economy. During our meetings on Capitol Hill with key lawmakers we also discussed workforce issues, funding for Department of Energy programs that support building energy efficiency, and buildings as key components of a resilient national infrastructure.

Understanding NFPA 285: Harmonizing Fire Performance and Energy Efficiency in Exterior Wall Assemblies

Posted By Nathan Pobre, Wednesday, May 23, 2018

Commercial building codes have been modified to require the construction of more energy-efficient buildings. Improvements to the building envelope, using continuous insulation solutions incorporating polyisocyanurate (or Polyiso) insulation, have played a major role in mainstreaming high-performance construction practices. To meet the demands of today’s buildings, architectural and design professionals must balance energy efficiency with whole building performance considerations, including fire safety. All construction materials, including foam plastics materials such as polyiso insulation, must provide a suitable margin of fire safety. The National Fire Protection Association (NFPA) 285 fire test is a large-scale wall assembly test used to determine the potential for flame spread from one story of a building to another through the exterior wall. With respect to wall assemblies in Type I-IV Construction, understanding and properly implementing NFPA 285 is a critical component for designing a compliant, high-performance building envelope.  

To learn more about NFPA 285, check out this free webinar which can help you:
1.    Understand the development history of the NFPA 285 standard fire test procedure for exterior wall assemblies containing combustible materials.
2.    Identify the NFPA 285 related requirements in the 2012 and 2015 editions of the International Building Code.
3.    Explain how engineering analysis of NFPA 285 test assemblies may be used to specify alternative materials.  
4.    Determine how Polyiso insulation can be used as an integral component of NFPA 285 tested and compliant wall assemblies.
