I've looked all over this site, and also Web searches - but I can't seem to find any discussion about, and the construction cross-section of, a commercial airliner's pressurized fuselage wall. Not the cross-section of the whole cabin, but just the fuselage wall from inside the cabin to outside.
More specifically, I'm curious as to what layer (and where in the cross-section) contains the pressurized compartment. Do the circular ribs (or whatever they're called) contain this layer, or is the outer skin the pressure vessel?
I've already seen the below questions (and their answers), but they deal primarily with cabin/cockpit window construction.
