Hello! I got the bright idea to drywall the exterior walls of my attached but unheated garage this week. I have put in the insulation, and am planning to put up the drywall next. However, it's pretty cold outside these days (Temps below freezing) and I've been reading that finishing drywall in cold temperatures is a no no. So, I'm wondering what my path forward should be.

1) put up drywall and finish in cold temps?
2) put up drywall and wait until spring to do any finishing work?
3) hold off on all drywall installation until spring, but leave insulation as is

If I hold off on drywall installation, is it ok to leave the insulation exposed/uncovered? Any input is appreciated.

Thanks!

Drywalling in cold weather just has to do with mud not drying. Go ahead and drywall and wait until warmer weather to mud.

Drywalling is done all of the time during the Winter months. You just have to run heaters in the structure while doing the mud work, and while it is drying.

And you are using 5/8 fire rock on the walls all the way to the roof on the side that's attached to the house right?
Some areas require you to use 5/8 on the whole gargae since it's attached.
Might want to check into that with the building dept.

As Joe said check your local codes some you must double layer the wall shared with the house. If you have no heat you can hang the rock but don't mud if you have heat go for it. If you decide to go ahead and finish it a fan may also be helpful to keep the air moving this will help it to dry.

How do you know the shared wall isn't already drywalled?

There's water in drywall mud, if it freezes it can get ugly. If it was mine, I'd hang it this winter and wait to mud it until it's warmer, or introduce a little heat to finish it off this winter..............

Thanks for all of the replies. The walls that are shared by living areas were already drywalled with the 5/8 thickness. I used 1/2 inch on the remaining walls after checking out building codes. I think I'll use a heater to finish things off, or just hold off until spring.

Thanks again for all of your input.

With a bit of heat and a fan, with insulation in there and a shared wall with the house, you should be fine - should keep the temps at 40 or above. Use setting compound since drying will be slow.
