Thanks aem, what you say make sense, for the most part.
However, I would like to comment on this statement:
"What you described is the dimensions for a sash replacement kit, not
a replacement window"
I hear what you are saying, but to some extent I disagree.
If I were able to remove all the parts of the casement window back to
the jambs (which would leave me with a 38 1/2" x 37 3/4") opening, I
could certainly buy a 2 view slider *replacement window* to fit into
the opening. That way I would not have to remove any trim or jamb.
Based on my measurements of the existing frames around each sash and
the frame around a 2-view slider, the glass area of the window will be
the same. (I am not going with a replacement casement because I know
that the center mullion is considerably wider than on wooden casements
or vinyl sliders.)
I guess it time to start pulling the trim pieces around the sashes
themselves to see how the window was installed.
Thanks again.
