SES Foam Wall Insulation Products Use Honeywell’s Low Global-Warming Material

Honeywell has announced that SES Foam has transitioned to Honeywell’s low global-warming-potential (GWP) material for wall insulation, with roofing systems to follow.

SES has introduced a 2.0 closed-cell spray polyurethane foam (ccSPF) formulated with Honeywell’s Solstice Liquid Blowing Agent (LBA) for use in wall insulation applications. SES joins a list of companies that have switched from hydrofluorocarbon (HFC) foam blowing agents such as HFC-365mfc and HFC-245fa to Solstice LBA in ccSPF systems, well ahead of environmental regulations calling for a phaseout of HFCs due to their high GWPs. More than 190 countries recently agreed to an amendment to the Montreal Protocol that would phase down the use of HFCs beginning in 2019.

Solstice LBA, which is based on next-generation hydrofluoro-olefin (HFO) technology, complies with changing regulatory requirements aimed at reducing climate impact, while also providing improved foam performance compared to HFCs. Blowing agents are an important ingredient in closed-cell foam, allowing it to expand and enabling its insulating performance.

“SES is proud of its commitment to sustainable solutions and innovation,” said Charles Valentine, chief operating officer, SES Foam. “Having built our open-cell foam business around sucrose-based technology, we believe that adopting Honeywell’s Solstice LBA in our closed-cell foam aligns with our customers and environmental focus. Our expertise is unique in that many of our staff are former spray foam contractors, so they have insight into customers’ needs, and can provide the support and products they require to succeed.”

“Honeywell is committed to helping industry leaders like SES create solutions such as using Solstice LBA in its closed-cell foam,” said Laura Reinhard, global business manager for spray foam, Honeywell. “Not only does Solstice LBA provide SES with an environmental solution, it has helped their 2.0 product formulation deliver foam performance.”  

Solstice LBA has a low global-warming-potential of 1, which is 99.9 percent lower than HFCs and equal to carbon dioxide. It is nonflammable (ASTM E-681) and is not a volatile organic compound per the EPA. Solstice LBA is listed under the EPA’s Significant New Alternatives Policy (SNAP) program. In Europe, it is not listed in the Annex I of F-Gas regulation and thus not considered an F-Gas. It is also registered under the European Union’s REACH program.
 
Solstice LBA is used in a variety of rigid foam insulation applications, including spray foam insulation, residential and commercial refrigeration equipment, and insulated metal panels, as well as flexible foam applications, such as molded and slabstock foam, and integral skin.

XPSA Supports Montreal Protocol Amendment Accelerating HFC Phase-Out

The Extruded Polystyrene Foam Association (XPSA) , whose members include the major extruded polystyrene foam (XPS) insulation manufacturers in North America, has announced its support for the Montreal Protocol amendment hastening the global phase-down of hydrofluorocarbons (HFCs) to protect the stratospheric ozone and mitigate the effects of climate change.
 
XPSA has expressed support for both the Montreal Protocol and the Environmental Protection Agency’s (EPA’s) Significant New Alternatives Policy (SNAP) Program, under which XPS manufacturers are transitioning out of using HFC-134a. XPS manufacturers have met or exceeded the timelines set forth and will continue to do so based on science and environmental stewardship. XPSA’s members are committed to eliminating HFCs from their products by the EPA SNAP deadline of January 1, 2021.
 
“The phase-out of HFCs will be a milestone within the XPS industry’s stewardship and sustainability objectives and a progression of our ongoing search for technology improvements to better serve our customers and protect our environment,” said John Ferraro, executive director of XPSA.
 
Replacing HFC-134a requires a reconsideration of the entire chemical makeup of XPS insulation products. The EPA understands that XPS manufacturers need time to identify alternatives to HFC-134a; assess and address risks of alternative components; analyze capabilities and make modifications to equipment, facilities, manufacturing processes, and worker safety and training programs; work with suppliers on equipment and component needs; build and engage in pilot- and plant-scale trials; obtain permits, approvals, and financing; and address commercialization issues such as ensuring production capacity to meet global market demand.
 
XPS’s properties heighten a structure’s energy efficiency, which both the U.S. Department of Energy (DOE) and EPA acknowledge to be one of the greenhouse gas (GHG) emissions reduction strategies. In fact, ASHREA and XPS industry estimates indicate that homes using XPS insulation sheathing save enough energy in the first year to heat over 500,000 homes in the U.S. XPS reduces GHG emissions by lowering the energy consumption of a structure, which diminishes the amount of energy spent in the distribution of energy, the delivery of which requires 3.34 units of energy to send 1 unit to a building for user consumption. Environmental Product Declaration (EPD) data shows that the reduced energy consumption due to XPS foam pays back the embedded CO2 multiple times over the life of a building.
