I am renovating a house in extreme south Louisiana. The structure is about
50 years old. I am removing everything inside, essentially gutting the
house interior to the studs. There is no "house wrap" of any kind...from
the naked inside, you can see the back side of the siding (which is still
sound). I want to install insulation , but am wondering if I can put
moisture barrier, (tyvek or some such) in each stud space...? and then the
insulation. If I put a barrier, do I lay it strictly flat on the flat part
or do I continue over and around the framing studs to make a continuous
barrier.

Thanks.
