good idea, but in the retrofit situation i do this:

cut back the drywall behind the casing and glue and staple 1 1/2" wide rips of 1/2" plywood to the hinge side of the jambs. works well

i hope thats not an exterior door because water could leak to the interior if theres no overhang or a driving rain.
also, weatherseal co. has silicone bulbs that work great in these apps.

two solutions to vapor seem possible, enclose the rot senesitive materials in impereable bariiers, i.e., poly to th einterior and exterior, or use breathable housewrap to the interior and still draft-stop every place possible.

will all you crazies with your right wing left wing democrat republican crap stop?! thats just political racism, a way for people to label others so they feel better about themselves. what makes us americans is that 99% of us will never know whats going on in our govenrment, EVER!

ABOUT WINDOWS:why not replace windows and be done with it. there is more than white vinyl ya know. the cost is high but you can address air and miosture leakage, eliminating maintenance, sealing areas AROUND the window(weight boxes, poor insulation, bad installation) that often get forgotten by most vinyl masters, adding water deflecting flashings, and while speccing your windows to mimic architectural details if necessary.

and lets face it, most windows built after the 50's arent serviceable overall anyway, and if they are the parts arent gonna last as well as new quality windows.

of course im speaking from a chicagoans point of view. maybe in southern cali and the like rebuilding single pane is fine, and maybe you dont mind putting up and taking down storm panels every year in the northeast.
