Foam wrap can reduce radiation and conduction because it is not a very good heat conductor.
it reflects the heat back
When a body is conducting, its mobility of ions( valence) is responsible for conduction. As mobility increase, conduction increase. That's why falling temperature reduce it and rising temperature increase it.
Conduction (Apex)
There is air between the inside and outside of the flask.

conduction
paper towel, tin foil, and newspapers. Those are the materials to slow conduction.
because they are good insulators

CONVECTION
yes
Foam contains pockets of trapped air which prevents conduction.

use paper bags
