A Groundbreaking Venture with the Potential to Revolutionize Construction Practices

May 2024
In a groundbreaking collaboration, Citizen Robotics and Insulspan® have unveiled Detroit's first 3D printed house, a pioneering venture set to transform the construction industry. The project, located in Detroit, Michigan, marks a significant milestone in the evolution of construction technology. Using cutting-edge 3D printing techniques, Citizen Robotics and Insulspan have demonstrated the feasibility of constructing a home in a fraction of the time and cost associated with traditional methods.

At the heart of this innovation is 3D printing technology. Instead of traditional construction methods that involve assembling materials piece by piece, a large-scale 3D printer extrudes a specialized concrete mixture layer by layer, gradually building up the walls of the house. This method not only streamlines the construction process but also allows for intricate designs and customization.

Specializing in forward-thinking construction methods, Citizen Robotics sought out Insulspan® to partner with because of the versatility and superior energy efficiency of the company’s Structural Insulated Panels (SIPs). SIPs are quickly becoming the future of construction, with their ease and speed of installation catching the attention of builders worldwide.

Forward-Thinking SIPs Hold the Keys to Energy-Efficient Structures - Roofing Magazine

March/April 2024
High-performance, energy-efficient buildings are a critical component of the global transition plan to a lower-carbon future. This puts enormous responsibility on the shoulders of building industry professionals who are challenged to adopt advanced building materials and progressive building envelope construction methods.

Building teams can meet this challenge by turning to structural insulated panels (SIPs), which can be used in roofs and walls of residential, multifamily and light commercial projects. A straightforward building system, the engineered panels are made by sandwiching the core of rigid foam insulation between two structural facings. Manufactured under factory-controlled conditions, SIPs can be customized to meet exact project specifications. The result is a nearly air impermeable building system. In turn, project designers can optimize energy consumption to meet the criteria of a high-performance structure: energy-efficient, low carbon and airtight for healthier indoor air quality.

Designing Energy Efficient Building Envelopes with SIPs - Building Enclosures e-magazine

Spring 2024
Building operations are responsible for 30 percent of global final energy consumption and 26 percent of global energy-related emissions, according to the latest findings from the International Energy Agency (IEA).

This puts responsibility on the shoulders of architects and designers to deliver high-performance, energy-efficient structures that can contribute to global sustainability targets. To meet this moment, project teams are carefully examining the building envelope, paying close attention to the selection of advanced materials and construction methods. As the physical and thermal barrier between the external environment and interior conditioned spaces, the building envelope has a very close relationship with a structure’s energy transfer and consumption. Consequently, the building envelope plays a critical role when it comes to designing an energy-efficient structure.  

One proven way that design teams can deliver a virtually airtight, low-embodied building envelope is by integrating structural insulated panels (SIPs) during the planning stages of a project. Read the full article here.

ACC Contributions of Insulation to the U.S. Economy 2022


  • The use of insulation in U.S. homes and businesses saves energy by reducing the heating and cooling loads of buildings, and therefore, reducing heating and cooling costs for home and business owners. In addition, by saving energy, the use of insulation helps reduce greenhouse gas emissions otherwise associated with the heating and cooling of buildings.
  • Beyond the benefits of the use of insulation, the insulation industry—including the manufacture, distribution, and installation of insulation—supports more than 1.8 million jobs in the U.S. and nearly $97 billion in payrolls that support families and local communities around the country.
  • Insulation materials manufacturing is a $24.9 billion business, and directly employs more than 40,000 people across 45 states. Further downstream, more than 6,000 jobs are supported through the manufacturing of accessories and fabricated insulation panels.
  • Indirectly, through its purchases of supplies, raw materials, equipment, and services, insulation manufacturing supports an additional 73,000 jobs in supplychain industries. Through the household spending of the wages and salaries paid to workers in insulation manufacturing and its suppliers, an additional 74,800 payroll-induced jobs are supported.
  • The combined direct and indirect economic activity from U.S. insulation materials manufacturing supports more than 188,000 jobs. These jobs generate payrolls of $13.9 billion. In addition, the combined economic activity supported by insulation materials manufacturing contributes $2.4 billion to state and local governments and $3.3 billion in federal tax revenues.

Green Builder Magazine, September/October 2022 - TC Legend Homes & Mariposa Meadows

October 2022
Green Builder Media's September/October 2022 Magazine highlighted two SIP projects and busts the myth that green buildings are unattainable for average American families and only for the wealthy.

TC Legend Homes has developed a tried and true homebuilding recipe to continuously meet zero energy performance scores of 10 or 20 below HERS net zero. This project’s walls consist of 6.5-inch SIPs that use a graphite-enhanced expanded polystyrene core wrapped with OSB. The roof is constructed of 10.25-inch graphite-enhanced SIPs topped with underlayment and asphalt shingles. Clifton chose a thicker, stronger roof panel to allow for foam inter-panel connection splines saving money on the lumber of I-joists splines, which have inherent thermal bridging heat losses. Read more on pages 32-35.

Meet Mariposa Meadows in the San Juan Mountains of Colorado near Telluride. This three-structure project uses insulated concrete form (ICF) foundations and SIPs for the walls and roofs. Since the project’s location is almost 20 miles away from the nearest grid, self-sufficiency was key. The structures incorporate a photovoltaic solar system, battery storage and a generator.

DOE Awards $32 Million to Accelerate Next-Generation Building Upgrades

14 March 2022
Meet VacRIPs - a nailbased retrofit panel solution with vacuum insulated modules installed. The Department of Energy announced mid-March a huge investment in next-generation building retrofit projects that will dramatically improve affordable housing technologies. Seven awardees will test renovation techniques that reduce disruption to tenants while upgrading the energy and environmental performance of buildings more quickly, affordably and effectively.

The SIPA collaboration team led by NAHB’s Home Innovation Labs & Oak Ridge National Labs will test an innovative wall system with VacRIPs in three residential, multi-family public housing buildings in Albany, NY. VacRIPs are a new retrofit insulation technology that will improve the energy performance of older buildings via the thermal envelope without displacing tenants. Here are the project highlights:

  • 3 multifamily 1980's apartment buildings with a total of 48 units will get a building envelope and mechanical retrofit to save about 70% energy from their current usage.
  • Over 50% of the energy savings will come from the thermal envelope improvements of a new, approximately 3" nailbase retrofit insulated EPS panel with embedded Kingspan vacuum insulated modules to provide an R-40 performance.
  • About $2M of the $4.5 M grant is directed to the direct retrofit construction costs of the structures (i.e. installation and purchase of materials & equipment). $900K goes to ORNL for all the testing and modeling and development of the updated SIP/RIP Installation Guide.  Another retrofit installation guide will be published with the completion of the study. Download the current 2015 RIP Installation Guide.
  • This project will include both the walls and roof of the building envelope enhancements with the new RIPs/nailbase.
  • Phase II of the project will take about 3 years to plan, install, and monitor results (including the 1-year energy monitoring phase).
