As I understand it....you don't need light to have radiant heat. Anything above the temperature of it's surroundings radiates heat. The suns heat waves hit the van panel, the panel heats up and radiates heat. But the panel can also conduct heat (to whatever it's in direct contact with).
A product like Reflectix reduces the transfer of radiant heat, light source or not. I'm not sure of it's effectiveness against conductive heat, tho I'm sure it has some with the air bubbles enclosed within the material. But it's probably most effective with an air gap between itself and the radiant heat source (pull it tight between the structural ribs of the van body instead of following the contour closely type of thing)
IMHO.
