This also has the effect of reducing the rate at which water evaporates from the surface of the food, evaporation requiring an input heat from the food. However as you point out aluminium is a good conductor of heat and so does not reduce heat loss by this mechanism although it does trap a layer of air between the sheet and the food.

Aluminium - Attributes and Properties of Aluminium Foil
May 28, 2002· Foil is a very thin sheet of rolled aluminium supplied in its pure form ('commercial purity') or in a variety of alloys and tempers which give a wide choice of tensile properties. The thickness of foil ranges from the thinnest currently produced commercially at about 0.0065 mm (or 6.5 µm) to the defined upper limit of 0.2 mm (or 200 µm).
