So far, so good. I had the 360 windows installed in Lithonia, GA, Nov 26 for roughly $4000.00 (separate kitchen bay windows, window over kitchen sink, and in the adjoining den the windows consist of two separate windows (1)8F10 x 4F11 and (2)12F4 x 4F11. Also in this particular room leading to the patio is a door with a storm door which I chose not to replace.

Since the installation, there has been a significant reduction of using heat in this section of the home. Lately, outside temperatures in the evening have centered around 32 degrees. The thermostat has been maintained around 70 - 71 degrees. Prior to the installation, this section of the home was extremely cold and drafty. I needed a blanket to lounge on the sofa while watching TV. For the first time in 15 years, I no longer need any covering while loafing nor do I have to turn the oven on in an effort to warm both of these rooms (kitchen and den).

Right now, I am an extremely happy customer!

Strongly recommend givng CHAMPION a try!
