Interior wall uninsulated garage

[Oskarfaglefelt]

Hello! Tearing down old plaster in the garage. No insulation behind as you can see, but there is plastic. What is its function? Shouldn't it be windbreaker fabric or nothing at all? I don't intend to insulate, just put on new plasterboard, possibly OSB behind, but maybe that's unwise from a moisture perspective?

How would you have done it? The garage is mainly used for storage/workshop, not for a car.

Rule no 1: If it ain’t broke, don’t fix it.

Ok, can you elaborate?

The plastic is supposed to prevent any moisture that gets through the tiles from reaching the wood.

If everything else is as it should be and those black dots on the sides in the picture are not mold, then rebuild it as it was before. Then there is evidently nothing wrong, no matter how it looks.

Furthermore, you can definitely use OSB behind it if the old plaster did not show any signs of mold or moisture damage.

OSB boards are waxed so they tolerate moisture better than plasterboard, so it's not wrong to install OSB.

The plaster should be changed

the plastic is probably there to prevent any moisture that gets through the brick from reaching the wood

but shouldn't it go all the way up then? It feels a bit half-done I think. But I have to let it stay.
