How do silvery walls control heat loss by radiation in a vacuum flask ...

The vacuum keeps convection and conduction from carrying heat inside. You can still have radiation heating the inside, but making things shiny helps keep that fro happening. You could get rid of the vacuum stuff the walls full of insulators, but it wouldn't work as well as a vacuum because they will still conduct some heat.
