Polar Windows

We just love our polar windows, they look great and they have helped to reduce the noise from the road in front of our house. We went with triple pane windows with crank outs. The quality is top notch and the price was very reasonable compared to other estimates we had for lesser quality products. They took our old windows away and even though one of the old windows broke as they took it out they didn't leave a single piece of glass behind. My only concern came when we had a home evaluation done and discovered that the windows leaked air where the windows meet the frame. We fixed this ourselves by siliconing around the windows on the interior and exterior and found that this fixed the problem. However, I believe this was more of a problem with our existing wood frames than how they installed the windows.
