Clopay garage door insulation is HFC free! Others?

It’s been hard to find out what blowing agents door manufacturers use in their polyurethane foams, but Clopay was finally forthcoming with a definite statement that they do not use HFC and are in compliance with California, NJ, Washingon and Candadian regulations on that.
They other known-low-GWP option is EPS, which is available in a lot of lower-end doors.
Has anyone else tried to get this information from other door manufacturers?
I first asked this here six years ago. I went with Jeld-Wen entry doors which have neopor (graphite enhanced EPS) insulation, but I still haven’t gotten to replacing my garage door. It looks like my options just expanded…
Edit: Here’s the text of what they say:
Clopay doors do not contain HFCs. All Clopay doors are compliant with:
-
California SB 1013
-
Washington HB 1112 – Hydrofluorocarbon Greenhouse Gas Emissions
-
Canadian regulations amending the ozone-depleting substances and halocarbon alternatives regulations
-
New Jersey A-5583/S-3919 – Greenhouse Gas Bill

That is great to learn. Were you able to find out any info on how well they seal? Without a good seal, an insulated door is less useful.
Most of them say, "Product complies with 2015 IECC air infiltration requirement of 0.40 cfm/ft2 or less (IECC, Section C402.5.2)," but beyond that they actually have a page with details:

Some are substantially lower infiltration. And they list the actual U-factor there too. Which is a lot more realistic than their R-value numbers which don't take into account the major thermal bridging.
