Homeowners in Georgia and South Carolina (or surrounding areas) have come to depend on Legacy EcoView Windows for low cost and high energy efficiency window options. As a consumer shopping for replacement windows near Savannah you may wonder “What does it take to truly be energy efficient?”
The National Fenestration Rating Council (NFRC) was established to rate vinyl windows in Savannah on key energy efficient criteria to determine how much benefit they offer your home. If you’ve seen an NFRC energy performance label on a new window, you may have noticed percentage numbers in four or five different boxes. These are the ratings you’re likely to see:
- U-Factor measures the amount of heat that escapes your home through your windows on a scale of .2 to 1.2. The lower the number, the tighter the seal.
- Solar Heat Gain Coefficient measures the amount of heat that is conducted through the window from outside on a scale of 0-1. The lower the number, the less heat gets through.
- Visible Transmittance tells you how much light the window lets in on a scale of 0-1. Here, you want higher numbers.
- Air Leakage (AL) rates the amount of air that seeps in through the glass into your home on a scale of .1 to .3. Again, lower numbers are ideal here.
- Condensation Resistance (CR) measures the window’s ability to resist indoor window condensation, which can sometimes occur when cold air from outside meets the warm air inside. Though much of this can be determined in AL (Air Leakage), CR (Condensation Resistance) measures this resistance on a scale of 1 to 100; the higher the number, the better the resistance.
