First usage of Honeywell's Solstice LBA in a spray foam system for wall insulation

[image_0]The blowing agent, which causes closed-cell spray foam insulation to expand and provides the majority of the foam's good insulating properties, was used to retrofit a residential home in West Lafayette, IN, USA. According to Honeywell, it marked the first application of the new blowing agent in spray foam wall insulation. Solstice LBA is already used to insulate high-efficiency refrigerators.[image_1_right] Whirlpool Corp. and Purdue University are transforming the 2,800 square-foot home, built in 1928, into a net-zero energy, water and waste structure that will house a world-class research laboratory. They selected Solstice LBA to increase the home's energy efficiency. "Closed-cell spray foam insulation (ccSPF) seals gaps, cracks and holes as it is applied, making it one of the most energy-efficient insulation products available today,” said Laura Reinhard, global business manager for Honeywell's spray foam business. "Solstice LBA has 99.9 % lower global warming potential than traditional hydrofluorocarbon (HFC) foam blowing agents, yet provides higher insulating performance than HFC blowing agents.”[image_2] According to Lapolla Industries, the Houston-based company that manufactured the foam, spray foam systems formulated with Solstice LBA demonstrate about 8 - 10 % better thermal performance compared to the systems formulated with HFC blowing agents. The spray foam installer on the project, ThermaSeal/Lakeside, a branch of Installed Building Products Company, also reported the additional benefit of a 10 % higher foam yield compared with previous systems. "We chose to partner with Honeywell because of the success we experienced using Solstice LBA in our refrigerator insulation,” said Ron Voglewede, global sustainability lead at Whirlpool Corp. "Since we knew Solstice LBA is also used in spray foam insulation, we thought it would be a perfect fit.” Whirlpool announced in January 2014 that all its U.S.-based refrigerator manufacturing would use Solstice LBA for insulation by the end of the year. According to Honeywell, the use of Solstice LBA allows spray foam manufacturers such as Lapolla to cost-effectively meet current and future energy efficiency and environmental regulations. Solstice LBA is a next-generation blowing agent with a global warming potential of 1, significantly lower than previous-generation HFC blowing agents such as HFC-245fa, which has a global warming potential of 858. Solstice LBA is non-flammable, has received EPA approval under the Significant New Alternatives Policy (SNAP) Program, and is VOC-exempt per EPA. Some of the benefits of the Solstice-enhanced ccSPF wall system included: Ease of sprayability8 - 10 % better thermal performance [1]10 % higher foam yield [2]Ultra-low global warming potential(GWP) of 1 (99.9 % reduction compared to HFC alternatives)Won't shrink or settle in wall cavities over timeSmooth foam surface finishApplied over a wide temperature rangeHelps prevent moisture and air infiltration In addition, Solstice LBA is: Non-flammable (ASTM E-681)Non-ozone depletingCommercially available VOC-exempt (U.S. EPA)Listed on TSCA inventory In addition to Solstice LBA, Honeywell's family of Solstice-branded products includes refrigerants for stationary refrigeration and air conditioning applications and automotive air conditioning, gaseous blowing agents, propellants, and solvents based on Honeywell's new hydrofluoro-olefin technology that helps customers lower their carbon footprint without sacrificing end-product performance. The products have been developed and are being commercialised by Honeywell's Fluorine Products business, a leader in the manufacture and supply of non-ozone-depleting refrigerants used by top air-conditioning and refrigeration makers worldwide, and blowing agents for energy-efficient foam insulation, as well as hydrofluoric acid and precursors for nuclear fuel.
