With blown in cellulose insulation, should you apply a vapor barrier before applying drywall?

Hi Curtis!

curtis..yeah you will want a vapor barrier.You could use poly sheeting or what I'd do is kill two birds w/one stone-use foil backed drywall,one of the many wonderful drywall products.However the availabity isn't as great as regular-call your local builders supply or better yet a local gypsum supply yard.
