- Solar Heat Gain Coefficient (SHGC). The solar heat gain coefficient basically measures the solar radiation admitted through a window. A low SHGC informs the consumer that the window will help a home remain cooler in the warm, summer months. SHGC values typically range from 0 to 1.
- Visual Transmittance. The visual transmittance (VT) measures the amount of light that enters through a window. The higher the VT, the more light comes through a window. Typical ranges are 0 to 1.
- Air Leakage. Windows are tested to see how much air they allow to pass through them. The lower the number, the less of a draft you will feel. The numbers range form 0.1 to 0.3. A window over 0.3 does not meet the qualifications for energy efficiency.

Solarban 60 and 70XL Low-e glass are glass products engineered to control solar heat gain, while dual weather stripping, warm edge spacer technology, and insulated glass panels all help increase the insulating ability of windows.
- Warranty. Make sure you purchase from a company that offers a good warranty. Your installation should also come with a warranty.
