The absolute best method to compare windows is to look at the NFRC rating for each one you are thinking about. NFRC labels that have received independent accreditation rate the general window performance using the U-Factor and Solar Heat Gain Coefficient (SHGC). The lower these ratings are, the better the window will perform. U-Factor or SHGC should be prioritized based on your climate. Regardless of the sales pitch, you should choose the NFRC ratings that are optimal for your climate and budget.

Q: What is an Energy Star window?

The Federal Government’s ENERGY STAR® window certification program assists you in selecting the best windows — one’s that are energy efficient and climate adapted. For windows to qualify, it must meet rigorous performance standards. These standards, which are based on NFRC whole window performance ratings, differ for each of the following four climate zones:

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

Yes — for our ENERGY STAR® products, you may be eligible to receive a 10% federal tax credit of up to $200 for windows and $500 for patio doors that meet ENERGY STAR® guidelines.

The Window Source can provide you with high-quality vinyl windows at a very affordable price because of our national purchasing power. Our low pricing and straightforward purchase procedure also enable us to operate at a high level of efficiency and pass the savings on to you.

Q: Is the installation as important as the window?

A window needs to be accurately measured to suit the opening and leave space for plumbing and squaring the new window. No matter how high the quality of the new window, if it is not squared and correctly plumbed, it will not seal and function well.

Q: How does the Window Source assure me of a great job at an unbeatable price?

*The National Fenestration Rating Council (NFRC) U-Factor is a certified measurement of the resistance to conduction of heat and cold by the entire product (frames and glass). The Solar Heat Gain Coefficient (SHGC) is a certified measurement of the ability of a product to keep out unwanted solar heat gain in the cooling season.
