My house just had about 40 old windows replaced in Nov 2011 with Crystal Windows Series 200 fully-welded vinyl windows equpped with Low E and Argon Gas. We are so happy and satisfied with these highly energy-efficient windows, the U factor is much better than that of Energy Star windows. The first night after the windows were installed, we were not used to what happened: the boiler and the heater were not turned on that often as usual, the whole was warm, andalso it was amazingly quiet even though our house is close to abusy high way. These are the best vinyl windows and I would recommend these windows to all of you.
