[Greenbuilding] Exterior wall construction--Again!!

[Lynelle Hamilton]

I'm building on waterfront and am looking for the exterior wall 
"assembly", if you will. When John spoke of the 'wetness' of the PNW.  I 
suspect I'll be similar.

The wall core is as follows:  Durasol or Concrete block (if block, 
cavities filled with insulating material)  cladded with foam on outer 
wall, then...what??  A friend, who developed a type of ICF, says just to 
put fiberglass mesh over the exterior foam and then stucco, that the 
foam is the vapour barrier.  I don't know about stucco at the 
waterfront, and  have toyed with the idea of cement fibre panels.  Stone 
(other than the "artificial" stuff) is not a possibility, except 
possibly for a partial wall.

FWIW, slab is poured concrete, insulated as much as I can.

With cement fibre panels come the need to somehow attach them (through 
foam).  From all the discussion on this site, I now have no idea if 
these panels are OK and if it good or not to try to attach through the 
foam.  Also, what depth of foam do I need to attain R40 or better in the 
wall?

Any ideas or suggestions as to where to research?  I'm building pretty 
much on my own (as is obvious from my questions)!

Thanks
