I have had carpenters at home and they have insulated my exterior walls. Now I have reached the point where I will begin putting up drywall everywhere. I was planning to have OSB boards behind all the drywall. However, I am missing something to fasten the top edge of the boards to, see my pictures. Do I need to put some boards there, or can I manage with just OSB and then drywall?
Now, I'm no builder, so I could be completely wrong, but - considering that the roof's vapor barrier seems to be folded down over the inside of the insulation, and considering how that white square thing is protruding in the right picture - is this really fully insulated, or is it that plastic should be added and then another layer of studs with insulation?
Otherwise, surely there should be studs at the ceiling and floor when mounting boards.

The vapor barrier is located beneath the visible layer of insulation (70 mm stud and insulation/vapor barrier/70 mm stud and insulation horizontally/110 mm frame and insulation/wind barrier/wood facade). What is visible in the picture is the vapor barrier from the wall that remains at the joint; it is clamped with a stud, leaving approximately 30 cm excess that serves no purpose. The overlap from the roof extends approximately 30 cm within the wall's vapor barrier, so it's done correctly. One might think that the carpenter should have laid it out under the battens, but he did not.
