Window Selection Tips
- Look for NFRC and Energy Star labels.
- Choose low U-factor for good thermal resistance in cold climates.

- Look for low heat gain solar coefficient. SHGC is solar radiation measure admitted through the window. The low SHGCc minimize heat gain in very cold climates.
- Select energy-efficient windows with low SHGC and U-factors to maximize energy savings in the temperature climate with hot and cold seasons.
