How do you lay underlay on a floating floor?

Beside this, which way does underlay go down for laminate flooring?

Get started by rolling out the underlayment with the silver side facing down. The tape strip should be flush up against the wall. Leave the overlapping section on the side that goes out toward the room. You'll need this section later as you continue to unroll your underlayment.

Subsequently, question is, what side of underlayment faces up? Important Tip: Depending on the type of underlay you are using will depend on which way up it's laid. If you are using rubber underlay, it should be face-down so the rubber is against the floor and the backing faces up. Foam underlay should also be face-down, with the coloured film on the floor and the backing face up.
