I thought this was interesting from a Green site I visit:
I was playing around with my new IR Thermometer this morning. It was 70 degrees in the house, 39 degrees outside. According to my IR Therm - the dual pane windows were at 67.8 degrees; the single pane windows were at 63.1. Just now I thought maybe I should have measured the frames... since the old frames are aluminum - new ones are vinyl... Ah, either way, you get the point. Even the glass temps are very different.
