I used this bubble wrap and foil to insultate my entire floor and heat
shield, all doors and over and in front of the engine. The area behind the
refrigerator was already insultated with fibreglass. I install a catylitic
5000 Btu heater behind the passenger seat. It sends its foul gasses out a
tube through the floor to the outside. I did not insulate the poptop and
wonder if this is feasible and what happens when you drop the poptop with
this stuff on the canvas.

My van is very warm in low 30's weather but wonder how it will do in a
really cold Wis winter. We'll see.

Good luck and let me know about the bubble wrat on the canvas and if you
resolve the adhesion issue. I find this site very helpful.
