wood paneling instead of drywall
We recently acquired a fixer upper. One of the things I've been bothered by is that two rooms only have wood sheet paneling on the walls with no drywall behind them.
I suppose this is ok for interior walls, but the case is the same with three walls which are exterior as well. I have not yet pulled one off to see what kind of insulation is behind it. (And given all the other snafus we've got on our list, I am a bit fearful to see what we find.)
One particularly odd thing (to me) is that there is a half wall between the family room and the dining room, which houses one of our two circuit breaker boxes. There is nothing in between the wiring coming out of the box and this wood sheeting. To me, that's a fire waiting to happen.
Am I correct in thinking that any wall should have drywall? Or should only the exterior walls? At least the wall facing the electrical box? Or none?
Any advice on this situation would be appreciated.
