Like the example of the insulated ceiling cavity, heat loss from supply ducts to the colder eave space will lower supply air temperature to the occupied space.

Insulation is a barrier that minimizes the transfer of heat energy from one material to another by reducing the conduction, convection and/or radiation effects.
