this is trick b/c then you avoid the heat flow thru the wood studs themselves - foam insulates the wood itself
it is all about the heating or cooling costs vs. the cost to construct
if you really want a high efficiency house, then get rid of all windows (!)
or pay $$$$$$$$$$$$$ for a high R window from Germany - another neighbor did that; makes no sense to me
