Subject: [Bldg-sim] Metal Building R-19 cavity insulation U-factor


I have a metal building wall construction with R-19 insulation between
the girts.
 
Now in ASHRAE 90.1-2004 Appendix A, Table A3.2 the single layer of
mineral fiber only goes up to R-13.
 
Any suggestion on how to determine the U-Factor for this wall?
 
Thanks.
 
Tim.
