vapor barrier

I am currently building a house in Southwest Virginia. The contractor is currently working on insulation and wall board (we will have plastered walls & ceilings). The insulation contractor plans to use blown insulation in the attic spaces. I inquired about a vapor barrier for the ceilings. He said that the wall board has a paper cover and that will serve as the vapor barrier so no additional vapor barrier was required. Is this correct?

I dont know what they are trying to pull on you . But yes you want a good vapor barrier in the home We put a 2mil poly on all walls and ceiling before dry wall or sand cote. if you dont have it In the winter the water vapor will get into the insulation and just kill it ED
