With metal frames and probably single pane glass you're fighting a

with a modern window that doesn't leak, doesn't transmit as much
summer heat, doesn't lose all that heat in winter and can be opened
now and then to enjoy a nice breeze. Factor in an energy credit on the
replacement cost and the choice is easy. HTH

Joe,

You are correct the windows are single pane. Still closing some air
gaps will make a large difference.

I agree that new replacement windows would be the ultimate solution
and this has been suggested but this would be well out of the budget
for this couple. There are actually three sets of identical windows in
a sun room type of situation and the walls are not stud construction
so there would be some unique issues installing a replacement window.
I would guess the cost would easily reach a couple thousand dollars or
more.

Thank you for your comments.
