It would be nice quality-of-life feature to someday add a ?framing + insulation? calculator to the detailed interface, but in the interim it?s not too bad to look up:

With 90.1-2007 open/at-hand:

? Table A9.2B details effective R-values for a layer of steel studs + batt layer, for a variety of spacing & framing dimensions.

? For wood framing, a parallel path calc can reference:

o R-1.25/in for two-by wood framing (See Table A9.4D if you are uncertain of actual lumber depth dimensions), and

o Table A9.4C to look up effective batt insulation when compressed into wood stud cavities for various dimensions.

I would expect these to line up very closely with the insulation+ framing layer the wizards generate. Opening a second instance of eQUEST to leverage the wizard dropdowns is an option I suppose, though I?m not sure if it will save you much time relative to tabbing a copy of 90.1.
