[Greenbuilding] Exterior insulation retrofit

I don't see the point of having a continuous layer as a nailbase. Also it
technically wouldn't comply as a nailbase for a lot of sidings
(technically). There are also some good studies also on how poorly osb
dries.  Also eps is pretty cheap and a light transport - and generally
available within a smaller shipping radius than a value added product that
adds weight.


Mostly I just hate osb and for ease of installation some poor guy has to cut
both foam and osb and then heft it in place.

Along a similar vein: this just popped up in Green Building advisor:

While nailbase is available in different thicknesses, this would appear to
be perhaps just a couple of inches. And while I'm not a big fan of OSB, this
is attractive from an air sealing and ease of installation standpoint.

Any comments or experiences?
