So the home had around 55 of those 20 pane units?
That’s pretty dang impressive. 50 regular double hung windows is usually a long day for me.
Which is funny, because when you think of it, 15 seconds per pane (7.5 per side) comes out to less than 5 hours for 1100 panes. It must be all the other stuff that happens in between. Like WCR & FB breaks
