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.

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.

Are tax credits available for windows and doors?

Yes, you may be eligible to receive a 10% federal tax credit up to $200 for windows and $500 for doors that meet Energy Star guidelines. These credits had expired in 2011 but the new law, "The American Taxpayer Relief Act of 2012" has extended these tax credits to the end of 2013 and retroactively for 2012.

How can The Window Source be so much more affordable than other companies?

The Window Source provides you with extremely affordable prices on premium vinyl windows because of our large national buying power. Also our low prices and easy purchasing process allows us to be extremely efficient and pass the savings along to you.

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.
