Just upgrade some single pane window to energy efficient double pane low-e glass at Three Kings,
So these windows were old single pane glass.
We removed the trim and installed double pane low-e glass to make the unit more energy efficient. Some were already double pane glass but many were failed.
The tall later is a 40 ft, so the top of these windows were at least 35 feet off the ground. We used a pulley with suction cups to lift the glass into place.
