I am about to undertake the fabrication of 66 double-hung, 8 over 8,
wooden window sash. I am hoping I might get some suggestions for the
right species of wood. I am considering mahogany because I want them
to last and I would prefer if I could find quarter-sawn for its
stability, but I am open to suggestions as I am certainly going to pay
a premium for the mahogany unless I find an acceptable alternative.
I will probably glaze with double strength glass in order to keep my
muntins to the original size. Perhaps, however, there are some new
types of insulated glass I might use that would allow me to use
smaller muntins.. Any ideas? I would also need a source.
