I've been using closed cell PE foam for years but only recently really knew what it was.
I get mine from work, it comes as part of the packaging for many items we have shipped to us. Everything from 1/8 inch sheets (roll material) to 1 1/2 inch panels.
I use the thin stuff as bottom insulation in my double layer hammock & wrap my video camera in it - the thick stuff I cut into sitting pads for use on top of logs or rocks around camp.
I can certainly see the value it has as an UL insulator.
I will check out your gear.

I shall be telling this with a sigh--somewhere ages and ages hence; two roads diverged in a wood, and I--I took the one less traveled by, and that has made all the difference.
