Some of you might have seen my struggles with my old single pane windows before (tons of moisture in the winter). We built a new attached garage last fall and changed our old garage into a family room. Since we were already doing vinyl siding on the garage, we decided to do the entire house. Since we were residing the entire house, we decided it was time to replace all the windows. Well, life got in the way and so I am just now getting back to the project. As of 6PM on Monday night, I officially have all low-e insulated vinyl windows and a new patio door to match. I have never cared much about heat lose when we were burning wood, but I'll be interested to see how the AC goes this next summer.
