Um, a little quick math here...
2x6 vs 2x4 does not yield a 1/4" gap but more like 2".
Maybe good old fashioned 2x4s that really measured ~2x4 instead of 1.5x3.5
is a better guess.
But again, if that's the reason, the installer should have explained it that
way, not blaming the previous installation.
I guess that assumes the installer even knew what he was looking at.



I've seen 2x4's go from 3-3/4x1-3/4 to 3-1/2x1-1/2 and lived in a
1920's farmhouse where the 2x4's measured 2"x4".

Many (if not most or all) of the modern clad windows are thinner than
the pure wood frame windows.

I'm sure that any of the above differences could have caused the
problem.
