Question: The window frames are in good condition and are, I'm pretty sure, Standard builder aluminum with 1/8" glass. One window salesperson said I should get vinyl windows with double-glazed argon/etc (which, of course, he was selling). Another suggested I would be find just replacing the glass with 1/4" thick double glazed safety glass.
Has anyone tried the glass replacement and been happy/not happy with it? What have you thought of it?
