Firstly, I am in agreement with Ken on the inadvisability of using any
insulation that has moisture-retaining capabilities.

The Iceguard is what I have in my two front doors, in the battery boxes and
under the rear seats.  It works great and I look forward to when I have time
to do the slider, the hatch and the cab roof, let alone the rear sides.   :)

I think this is the link you're looking for:
