Indoor or outdoor gypsum

[HeH2]

Hello everyone,

I am going to renovate the interior walls of my unheated garage. Currently, I have (from the outside in) wood paneling, paper, and then new insulation between the 90 studs.

My question is whether I should then have plastic and drywall, or if it is sufficient to install exterior drywall inside (or could I encounter issues with moisture penetration?). I then plan to paint the wall.

Do you have any other suggestions?

The outdoor plaster is treated with a silicone-based impregnation and is therefore not suitable for painting.

The plastic you put in the walls doesn't really have the function you think. The plastic is not meant to protect the drywall but to protect the wall from becoming damp in the middle from the humid indoor air. That is, indoor drywall + plastic is not the same as outdoor drywall.

Are you going to have a heated garage?
If it is unheated (or only low heat), it is usually recommended not to use plastic at all.

And,
if the garage is not going to be heated,
there is no reason to insulate at all.

Or can the fine-tuners come up with a good reason?

Fire protection requirements, mildly heated (around 10°), occasionally wanting warmth once or twice a year.
Thinking about a heated garage in the future or considering future resale value.

Want more reasons?

Coming up with a couple more: More even temperature, not scorching hot in the summer.

Above all, you don't get frost in the storage (not in Skåne at least) even if it's below zero outside, but it's probably more about how cold it is outside than about the insulation.

Above all, you do not get sub-zero temperatures in the storage (not in Skåne at least) even if it's below freezing outside, but that probably depends more on how cold it is outside than on the insulation.

Fun, fun, fun!

Can't the cars handle a little frost now? My Volvo 2008 does, at least.
