May not be the best way but in the past we have cut stips of Tyvek and stapled them up then insulated.
It still allow the wall to breath and cut down the air flow a great deal from the outside.

Make sure you add fire blocking at the top and bottom of these walls, and in the middle if the ceilings are over 8' tall.

Joe, the actual code on fire blocking is anything over 10' tall.

Around here on exterior wall we get around fire blocking as most homes are insulated with fiberglass.

Barb (gma2rjc) can tell you approximate costs and any other helpful hints if she sees this or we all yell her name loud enough. She did the DIY spray foam thing and was happy with the cost and results, and this IS a DIY website!
You may be surprised how affordable it is!

Spray foam or rigid foam cut to fit in the stud bays that is then sealed to the studs and sealed up tight.

there are no cracks. its T&G wood.

ok, i just looked again. i found a bad spot. it looks like there is the back side of the asphalt siding. but it could be that the paper, if it was installed, has been damaged = gone, in that spot.

i will not "know" until i go to put the new window in. and that is probably(if i go with the okna windows) a month off.
