Building in stages through seasons

[forAK]

So, the thread in the heating section (Leaving my building unheated for the winter) got me thinking about my situation.

I'm in the process of building a 40x40x14 addition to my existing shop 32x28x9.5. I'm at the point of open studs/trusses, the metal roof is on, the osb sheeting is on but the garage doors are not. Pretty much dried in. Kind of ran out of money as some other surprises hit. Anyway, the thought now is to just leave the shell open and work on it throughout the winter. So right now I was thinking about adding the cardboard baffles and vapor barrier/sheetrock on the ceiling and continue wiring and such until I can afford the blow in insulation and continue on all winter.

The question is - Since it's an unheated space would I need to worry about condensation in the attic space ruining the sheetrock/baffles or blow in?

There should not be any condensation with equal temp's inside/outside. There might be a posibility of a little under the metal roof with AM sunshine.

If you have housewrap/tyvek I'd put that on with a lot of cap nails. That will help protect the osb, plus you can go across the garage door opening as well but the sheeting will need some support over the large span otherwise it can rip in high winds.

Personally I wouldn't do the drywall with an open structure.

In preparation of not being able to complete the job, I put on a couple of thick coats of oil based primer so the osb would be protected. I thought I'd be wasting the tyvek as it would still get hit with the wind and sun. I've seen a lot of places being built with tyvek over the winter and it not last. I was thinking about just building some 2x4 walls to fill the openings just to keep the chill off while working but then I might end up with a temperature differential that might cause condensation. If not during winter, maybe spring.

Do you think the rock will swell with moisture in the air?

Mud will never dry if the air is damp and the sheet rock acts like a sponge in my opinion.

Sheetrock in my unheated garage has not fared very well the last 7 years. OSB will be fine if covered.
