   Here's the equivalent of another "bump" for you, but I also wanted to ask--is the new siding going over existing clapboards ("bevel" siding) or what? Or are you taking old siding off and putting new on the old sheathing? We resided a house up here (Michigan) with vinyl and went over wood clapboards and just used "fanfold" Styrofoam (1/4" thick) under the new siding. (That was to mainly prevent noise from the siding vibrating in wind and also to give a flat surface to put the new siding onto.) Didn't have to use house wrap.

   I'm thinking if you aren't stripping off old siding, you may not need housewrap either. If you want more insulation value than 1/4" foam, you could probably use 3/4" or even 1" Styrofoam. I am always concerned with foam under siding acting as a vapor barrier, and it would not be on the "correct" side for New York, but if you don't tape the seems or anything, I suppose it wouldn't really be much of a vapor barrier. Much more than 1" of foam though, I would think, would make it hard to nail the new vinyl.

   Anyway, maybe this will promt some others to respond.

   In the event you fail to receive the information you requested you may be able to find it in the achive listing of old threads on Breaktime.

   If you scroll up in the upper left corner of your screen there is an advanced search function that will take you to a page of instructions directing you to previous threads dealing with whatever you type in the search bar.

   If you type in 'vinyl insulation', 'rigid insulation'  or other keywords of the subject matter you'll get a supply of data from those old threads.

   However, if one designs to construct a dwelling-house, it behooves him to exercise a little Yankee shrewdness, lest after all he find himself in a workhouse, a labyrinth without a clue, a museum, an almshouse, a prison, or a splendid mausoleum instead.

   Polyisanocurate insulation is the best r-value per inch, I think it's the most often used in that sort of application.  There was an article about foam sheathing in FHB a few months back, it was a good introduction.  Sealing the foam well is probably more important than the type of foam- proper air sealing will make a huge difference on an old house.  Tape the foam panel joints well, and use spray foam to seal up edges and gaps.
