Q & A: is aluminium foil an insulator or a conductor ...

That same electrical conductivity makes the aluminum highly reflective. As you say, that reduces the loss of heat by electromagnetic radiation. I'd forgotten to include that. As far as the convection goes, since the foil gets almost as hot as the food, and air can convect past the foil, I don't think the foil reduces that heat loss much.
