Wood studs on stone surface on the second floor, ok?

Hello!

I've heard that you shouldn't place wood directly against stone because condensation can easily form on stone, leading to mold?

Here, I'm enclosing an old chimney to create some nice wall space to put up shelves, etc. But it was a bit tricky to get the studs in with protection underneath, so I thought, "Well, it's inside the house and on the second floor, this stone floor isn't going to get cold enough for condensation, so I'll just go ahead!"

However, I'm starting to get nervous about this and I'm considering whether to lift up the posts and insert some kind of plastic or something. What do you think, is it worth the trouble? Or is it safe as it is?

I have stone slabs in the kitchen and there is never any condensation on them. Condensation occurs when warm and humid air reaches a cold surface that cools the air so that the air can no longer contain as much moisture. If there is no thermal bridge to any exterior wall, then your stone floor reasonably has the same temperature as the air in the room.

Is there enough distance between the chimney breast and the studs?
There are fire safety requirements for that, aren't there?

I have stone countertops in the kitchen and there's never condensation on them. Condensation occurs when warm and humid air reaches a cold surface that cools down the air so that the air can no longer hold as much moisture. If there is no thermal bridge to an exterior wall, then your stone floor presumably has the same temperature as the air in the room.

Is there enough distance between the chimney and the studs?
There are fire protection requirements around that, right?

hi yes that's exactly what I thought too, thanks for the answer! regarding fire risk, the chimney has been out of service for decades, so nothing will get warm there, but it's nice to point it out anyway
