Hi Gang:
Every once in a while, a model appears.
I have forgotten how to do a metal frame wall with infill batt insulation. The wall is a 2 x 6 @ 24" centers with 6" R-19 insulation. I also know that there is 4 " board insulation continuous across the steel.?
Where can i go for the equivalent R-values?
Thanks in advance.

Hi John,
Per ASHRAE 90.1, Table A9.2-2, with R-19 between 6? framing @ 24? O.C., effective R-Value is R-8.6 for the frame/batt layer. Then add the R-Values of the continuous layers to get the assembly R-Value.
Regards,
~Bill
