I have a very old place that needs insulation upgrading as well as new siding. I was thinking about rigid foam and board and batten siding. The original sheathing is 1″ rough lumber running horizontally and it will stay. Can the board and batten siding be nailed on right through the proposed 1″ foam board or do I need to put on strapping as well?
Thanks for any suggestions..

Did this 15 years ago to my brother's house. 1" SM Blue covered with vinyl siding. Still looks good after all those harsh winters (canadian, eh) The house is about 100 years old and was originally covered with white pine shiplap.
Every opening in the building envelope (doors, windows, etc.)is a place where the insulation will be seen on edge. To prevent this, you will have to rip 2x4 stock down to 1" thick and build up the areas around the doors and windows. You will also have to do this along the bottom edge (starter strip) as well. Using 5/4 deck planks ripped to 2 3/4" might also suffice.
Exterior and Interior corners must also be built up so that the siding has a solid nailing surface.
Light fixtures, exterior plugs and the hose bibb will all require adjusting to clear the thicker wall. Don't bring a propane torch anywhere near the foamboard....or poof!
After you have installed the foamboard ( I used 2" roofing nails) and the furring strips (2 1/2" deck screws), go around and fill any gaps with expanding foam.
The siding you chose will probably require 3" galvanized finish nails
The biggest hassle was working around the service mast. Ended up using prefinished sheet metal behind the pipe and meter. No insulation or siding, just sheet stock on the old siding. Started the insulation and siding about 12" either side of the mast. Really should have had hydro cut the power, looking back. If you are considering upgrading your service,(and by that I mean, a larger pipe) now would be the time. Just sneek in some siding while the electrician is on break.
