Hello!
Last spring we made the mistake of using pressure-treated wood to frame around a balcony door we installed. We had bought the wrong dimension of the wood, so since it was a Sunday and eagerness took over, I thought that the beams left over from the deck project should suffice.
I've realized in hindsight that this was foolish!! It's about 4 meters that I've built into the exterior wall, what can happen? Can there be a bad smell indoors because of this little? Anything else, hazardous to health?
