When you are thinking about investing in new windows, you need to know what to consider when making such an important home improvement. The first thing you need to take into consideration is the company's reputation. Only do business with a highly respected company with years of experience. The next thing you need to pay attention to is if the window is Energy Star certified. Pay attention to the Energy Star and National Fenestration Rating Council window labels. Here's a quick cheat sheet.

Energy Star/National Fenestration Rating Council-Facts You Need to Know:

  • U-factor, or U-value, usually ranges from 0.20 to 1.20. Keep in mind that the lower the number, the better the window will be at keeping your expensive heat in.
  • Solar heat gain coefficient is between 0 and 1. What you need to know is that the lower the number, the better the window is at blocking unwanted heat from the hot sun. In warmer climates, you want the lowest number. In colder climates, a higher number is better.
  • Visible transmittance just shows you how much visible light a window lets in. Usually this number is between 0 and 1. As the number gets higher, so does the light.
