What is the best way to compare windows?

There is only one reliable way to compare windows and that is by asking for the NFRC* rating for each window that you are considering. NFRC labels are independently certified and rate the whole window performance by U-Factor and Solar Heat Gain Coefficient (SHGC). The lower these ratings are the better the window will perform. The priority of U-Factor versus SHGC depends on your climate. You should ignore all the sales hype and choose the best NFRC ratings for your climate at the best cost.

What is an Energy Star window?

Energy Star is a window certification program administered by the Federal Government to help you select energy efficient windows optimized for your climate. A window must meet minimum performance criteria to qualify. These criteria are based on NFRC whole window performance ratings and are different for each of four climate zones as follows: Northern Zone (blue): U-Factor of .30 or less, SHGC any North Central Zone (yellow): U-Factor of .32 or less, SHGC of .40 or less South Central Zone (orange): U-Factor of .35 or less, SHGC of .30 or less Southern Zone (red): U-Factor of .60 or less, SHGC of .27 or less

Does The Window Source have Energy Star windows and doors?

Yes, any window or patio door ordered with a LowE glass upgrade will qualify for the Energy Star guidelines for the climate zone where purchased. This guarantee always comes in writing on your contract specifications so you will be assured of ordering and receiving the best LowE glass that is optimized for your particular climate zone.

Do you use sub-contractors?

Here at Window Source of the South we do not use sub-contractors, all windows are installed by our own drug and background tested employees to ensure a proper and safe installation.

Is the installation as important as the window?

Yes, a window needs to be properly measured to fit the opening and allow adequate tolerance for pluming and squaring the new window. If the new window is not properly plumbed and squared it will not seal and operate properly no matter how good the quality of the new window.
