Does anyone know of a SIP manufacturer using a low GWP blowing agent, like Honeywell’s Solstice blowing agents?

Steven,
Most SIP manufacturers use expanded polystyrene (EPS) foam, and most EPS manufacturers use pentane as a blowing agent. Pentane has a low global warming potential, so you don't have to worry much about global warming if you choose SIPs with EPS.
