Though I cannot comment on the need for a stained glass studio, I
would like to direct your attention to a study on protective glazing
that was funded by the National Center for Preservation Technology
and Training (NCPTT) in the late 90's. The results of the study are
astounding in terms of the micro-environments created by certain
types of protective glazing. The information presented in the study
should help with the decision regarding adding protective glazing
back in again.

I would also urge you to avoid epoxy repairs to the wood wherever
possible. If skilled carpenters are available, wood dutchman repairs
using similar species will perform much better over the long-term.
Of course, complicated traceries and predominantly old-growth wood
make the concept of epoxy repairs more tolerable for vertical
surfaces. Regardless, my personal opinion is that wood window sills
should never be repaired with epoxy.
