Which side of aluminum foil keeps heat in?

The reflective surface will reflect heat and the matte side will absorb heat. If you’re baking or defrosting, the matte side will absorb more radiant heat and reflect less infrared heat while the shiny side will reflect more of both, so it makes more sense to bake and defrost with the matte side facing up.

How long does aluminum foil keep food hot?

Is aluminum foil a good insulator of heat?

Aluminum foil, also called tin foil, makes an excellent insulator, and in some situations, it works better than materials like cotton or paper. Aluminum foil is not best for every situation, though, so using it correctly is an important part of saving energy.

How do you keep food warm in tin foil?

For short-term warmth, you can use foil, but it will not keep the food warm for long. Foil conducts heat, letting it pass through to outside of the food.
