I know the batt insulation has a vapor barrier, but does any vapor barrier need to be put down in the attic before they blow insulation? Thanks.

If the attic has batt insulation with a vapor barrier, no other vapor barrier is needed.

They plan to blow insulation over the sheetrock ceiling. Does it need a vapor barrier? The ceilings will not have batts except in the vaulted areas.
