Vapour barrier underlay over insulated wooden subfloor

[daven1986]

Hi all, I've seen a few threads on here which do not recommend using a vapour barrier underlay with a ground floor wooden subfloor due to condensation being trapped and damaging the subfloor. I was wondering if this advice still holds if the wooden subfloor is suspended and insulated?

I ask because my laminate requires a vapour barrier underlay to be under warranty.

Thanks
