Foil backed underlay necessary?

bobnotthe builder · 19 Aug 2013

If you're putting down an engineered wood floor on top of original pine floorboards (ground floor) do you need foil backed underlay?

Got two quotes from different floor installers - one going to use Timber Tec OX2 foil backed underlay, the other going to use cush 'n' wood 4mm underlay. Is the foil backed one necessary for damp protection? Any difference?

Thanks

Do not use foil backed or any poly sheeting over wood subfloors.
