4th Generation Foam: The Key to Global Energy Reduction

By Ryan Spencer

Innovation has been an inherent attribute of the spray foam industry from the beginning, providing the global insulation market with cutting-edge, high-performance products that are constantly evolving to meet the needs of end users. Recently, those needs have focused on one major issue facing end users all over the globe: climate change. Of course, spray foam insulation plays a critical role in energy efficient building initiatives and has delivered tangible benefits in terms of reducing buildings’ energy needs. However, a comprehensive approach to maximizing SPF insulation’s role in combatting climate change involves not only the material’s real world performance, but also the composition of the spray foam itself. Indeed, industry leaders like Lapolla have spearheaded innovative efforts that mitigate the environmental impact of SPF’s constituent elements.


November 6, 2015 marked Lapolla’s one-year anniversary publishing their CCRR report for Foam-Lok 2000-4G, their 4th generation 2.0 lb. interior insulation foam featuring Solstice LBA (liquid blowing agent). Lapolla celebrated two years of hard work from development to the completion of full testing for code compliance with AC377.

The first year as a commercial product for the Foam-Lok 2000-4G was extremely successful. The customer response to the product has been reflected in the increase in sales and by reports of satisfaction with the performance of the material on every job in all types of applications.

Lapolla was also pleased to be included as part of the Presidential Climate Policy and Action Committee, and was twice recognized as meeting our goals for conversion of its product line to the new blowing agent.

“Lapolla continues to support this climate action policy as we continue our customer conversions to a more environmentally friendly blowing agent having an ODP or ‘0’ and a GWP of ‘1,’” commented Steve Williams, Technical Director at Lapolla.


Partnering with Whirlpool Corporation and Purdue University, Lapolla provided the new Foam-Lok 2000-4G system for wall insulation in the ReNEWW House project, which entailed retrofitting a house built in 1928 into a modern Net-Zero home.

The Foam-Lok 2000-4G insulation plays a key role in the home’s Net-Zero design by preventing air infiltration and leakage, which would otherwise contribute to wildly inconsistent indoor temperatures and excessive energy consumption. The ReNEWW House project is ongoing, with the post-construction phase involving extensive data collection to analyze the home’s energy performance.

Foam-Lok 2000-4G represents cutting edge technology that allows homeowners to reduce their carbon footprint and create an environmentally friendly home with the added bonus of decreasing heating and cooling costs. Spray foam insulation is at the top of the recommended product list for architects and builders.


President Obama launched his Climate Action Plan in 2014, invoking a “moral obligation to act on behalf of future generations.” The plan outlines three broad initiatives for addressing climate change, one of which focuses on cutting carbon pollution in the United States. One of the five carbon pollution-reducing strategies entails the reduction of greenhouse gas emissions, especially Hydrofluorocarbons (HFCs).

The Climate Action Plan put forth by the Obama Administration outlines three broad initiatives:

  • Cutting carbon pollution in the U.S.;
  • Preparing the U.S. for the impacts of climate change;
  • Leading international efforts to address global climate change.

On October 15, 2015, Lapolla CEO Doug Kramer was invited to participate in a roundtable discussion at the White House with other business leaders, as well as the U.S. Secretary of Energy Ernest Moniz and EPA Administrator Gina McCarthy, to discuss the private sector’s commitment to reduce the use and emissions of HFCs.

“In 2014, Lapolla made a commitment to the White House to transition all lines of technology by the end of 2016. We are significantly ahead of schedule; as of now, our entire product line of foam systems no longer uses high HFCs,” stated Doug Kramer, CEO of Lapolla Industries. “In fact, we are urging others in our industry to follow our lead and transition their products ahead of the EPA target date.” He further commented, “Now our goal is to transition the global markets to Next Generation 4G technology. Lapolla’s 4G already has approval in the United States, Europe, and other important regions of the world.”

For its part, Lapolla has been a leader in developing new insulation technologies that create more climate-friendly products, like Foam-Lok 2000-4G, that are less harmful to the environment. In fact, Lapolla has spray foam technology for both insulation and roofing systems and is in the process of converting all of its customers to this next generation technology.

“The impact of this new technology is profound,” said Kramer. “This is simply the best and most environmentally-friendly product in the marketplace, and we’re proud to be the first global supplier of an approved next generation wall foam system.” •
