Where can I find XPS insulation with HFO blowing agents?


Can I purchase XPS made with HFOs?

We start a new residential build Spring 2020. Can I purchase XPS panels with HFOs anywhere? If not, any idea when they will be available? If they aren't available, is my best alternative still mineral wool?

No answer means nobody is fibbing.   I am looking at EPS (cheaper) vs. mineral wool board (doesn't burn and maybe is acoutically better too).  In both cases need to go with 2-in. vs the 1.5-in. notionally acceptable if using XPS.

Fibran, in Portugal, produces XPS with HFO.
