I have received so many compliments on these windows and they are actually the original single pane windows that were built into the home back in the early 60's. Rhino Gerkin makes a very similar window in what they call a mill finish which Is very close to this stainless steel looking finish. I do not know where you live but you can google them and see if they service your area. Vista Wall makes a comparable looking door to match the Rhino windows. They have a very commercial store front window look to them. Hope this helps.
