What is the best underfloor insulation?

There are two main types of insulation – bulk insulation and reflective foil insulation. 
Extruded or expanded polystyrene insulation boards can be used in underfloor insulation. This type of insulation can also be combined with reflective foil to form a blanket that helps create an insulated barrier from the outside air. 
The other option is using rolls of polyester R2.5 insulation. Polyester is resistant to vermin penetration.
