underlay laminate floor

[sheldon128]

Hi - i'm installing a laminate floor in a ground floor openplan lounge/dining room. The floorboards have been overlayed by chipboard to level them by the previous owners. I'm putting down quickstep.
Question is - which underlay to use? There seems to be a lot of conflicting advice, regarding foil or no foil, how thick etc.
My old builder recommends Howdens underlay.
Any thoughts gratefully received!
Thanks

Is there any special requirements of the underlay, other than to dampen down the sound of foot traffic?
ie damp, underfloor heating?

Thanks - not really anything special.
Needs to keep noise to a minimum and keep the room warm (no underfloor heating).
should I use fibreboard or a foil-backed underlay? I am concerned that damp condensation might be a problem with the foil?

If you have no special requirements over than noise reduction of foot traffic, then just about any standard underlay will do.
I would personally be happy to recommend using 3mm foam, relatively inexpensive and does the job!
