Honeywell Solstice® Liquid Blowing Agent:
The Challenge: Provide an insulation solution to meet aggressive energy goals for a 2800 sq. ft. home, built in 1928 in West Lafayette, Ind. The home is being transformed into a net-zero energy, waste and water home, sponsored by Whirlpool Corporation and Purdue University.
The Solution: A new closed-cell spray polyurethane foam (ccSPF) system for wall insulation developed by Lapolla Industries, formulated with Honeywell Solstice® Liquid Blowing Agent (LBA).
Closed-cell Spray Foam Insulation: An Easy Choice
Even with so many options for residential insulation available on the market today, the decision to use spray foam insulation for this project was an easy one for general contractor Grant Giese, president, Green Goose Homes.
“We have used spray foam in our homes for a number of years now. We use it largely to stop air infiltration and provide great R-value, and we’re doing the same thing here,” said Giese. “We’re trying to bring this home from being an energy hog to net-zero, and the spray foam is going to play a huge part in that.”
“Closed-cell spray foam insulation 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, Spray Foam for Honeywell. “Now that Solstice LBA is commercially available, it is exciting to have it be earmarked for sustainability projects such as this one at Purdue.”
For many, the thought of retrofitting a home’s insulation brings to mind a messy, disruptive process that involves removing the interior walls own to the studs, but Giese had a different process in mind. “We primarily use ccSPF in new home construction, but a lot of people don’t realize how easy it is to retrofit,” said Giese.
“This home has all plaster and lath on the inside, which is nasty to work with and remove, and harder to repair and replace. So it made a lot more sense for us, with the siding in the state it was in, to just remove the siding and spray from the outside. It’s really turning out quite well.” – Grant Giese, President, Green Goose Homes
Lapolla’s new spray foam system received high marks from the spray foam installer as well. “My expectations were exceeded. The yields were about 10 percent higher than we expected, which is fantastic,” said Brian Eustis, manager, ThermaSeal / Lakeside Insulation, an Installed Building Products Company. “The [application] guys liked it better because it rose later. The front end was a little slower, the back end was a little faster, so they could control it better. Overall, the product looked fantastic and the finished product looked great.”
Mary Bogdan, senior principal scientist, Honeywell Fluorine Products, agreed. “The applicators did an excellent job of applying it. We had a broad temperature range from morning to afternoon, and it performed equivalently well across all the temperature conditions we experienced.”
With the deep energy retrofit complete, Whirlpool and Purdue are installing a world-class research laboratory in the home, which will provide continuous monitoring of all the products and systems that use the home’s energy, to provide valuable insights on technologies that enable sustainable living.

Solstice LBA is Commercially Available
“Honeywell started up its manufacturing facility for Solstice LBA in May 2014,” said Bogdan. She further stated that Solstice LBA is a key replacement for HFC-245fa and other HFC blowing agents because of these key advantages:
Ultra-low global warming potential (GWP)
compared to a GWP for 245fa
A slightly lower molecular weight so less material can be used in a system
In addition, Solstice LBA is:
