   i take it you are talking about floor trusses above the garage..

    in your climate, i would blow the space solid with cellulose.. either thru the band joist from each end to the middle or cut a slot in the ceiling drywall and blow from the center out

   Actually these are roof trusses on the garage - no living space above.

   Hear tell that a good primer (Zinnser's?) topcoated with another coat or two of quality latex serves as a pretty good vapor barrier.  Then have the attic space blown full of insulation.  The guys that specialize in blown can recommend the best way.

   Thanks for the response.  I thought I had heard something like that as well - was hoping to have a few of the resident experts recommend such a thing - so I could do it with clear conscience.

   Anyone else willing to stick out their neck and bless a painted on vapor barrier, and then just letting blown in insulation sit on back side of rock.

   Thanks,

   What do you need a vapor barrier for in a garage?

   If I read this correctly this is a garage with truss and a attic space, just add insulation and properly ventilate the attic. We do not vapor barrier attic spaced ceilings here in the northwest. If you want to add extra insurance to the job put two layers of pva primer, most brands this will give you a one perm barrier.
