aluminum foil
 

Would there be any advantage using aluminum foil in the oven on pans by
placing the foil dull side up?...

So far with respect to the question, resources explaining this do not give
technical reasons for their explanations.

Shiny side reflects more heat than the dull side.

From the Reynolds Wrap website (www.reynoldskitchens.com):

Which side of Reynolds Wrap® should I use, the shiny or the dull side?

Actually, it makes no difference which side of the Reynolds Wrap®
Aluminum Foil you use — both sides do the same fine job of cooking,
freezing and storing food. The difference in appearance between dull and
shiny is due to the foil manufacturing process. In the final rolling
step, two layers of aluminum foil are passed through the rolling mill at
the same time. The side coming in contact with the mill's highly
polished steel rollers becomes shiny. The other side, not coming in
contact with the heavy rollers, comes out with a dull or matte finish.

Except for radiant heat which is reflected.

I use it with shiny side toward the food, in spite of knowing the
above. I just makes me happier. OTOH, if I happen to cover a dish the
'wrong' way, I seldom reverse.

From a heat source that glows - lamp, rod or flame. I don't think
that heat radiating from a hot oven wall will be reflected.

Not that it makes much difference with foil, but my oven glows a lot.
Radiant electric coils. Mostly, even with the shiny side whichever
way I want it, I use it to keep selected portions moist and keep them
from getting too crispy, e.g. turkey wings. For the small difference
it makes, I try to do shiny side out.

Not something I become hysterical about.
