Hi, does anyone know how to figure out the R-value from the table?
If I have wood frame R-13, does R-0+9.3 mean I have 0 cavity insulation in the 16"o.c steel frame?
Also, I notice there are R-13+5 and R13+10. I didn't see any footnote explaining what the 2nd value means. Is the 2nd number also continuous insulation(ci)?
Thanks a lot.
