Do you realize that R38 fiberglass is about 11" thick? Thats some pretty thick wall framing you have there. As an insulation contractor, I can tell you that R-11 is 3.5"(2x4 framing) and R-19 is 5.5" (2x6 framing). Even if ya cram it all in the framing,, you will only end up with R-11 or R-19.

good luck
