Relevance of window performance ratings
Living in an energy-efficient home lets you enjoy the comfort and reduced energy costs. An efficient way of realizing this kind of home is by replacing your old and drafty windows with energy-efficient ones. Look for windows that come with the National Fenestration Rating Council (NFRC) seal, which indicates good energy efficiency.

The NFRC

The NFRC is a non-profit organization that helps reassure consumers that they are getting an energy-efficient product. They test, certify, and label various fenestration products, such as windows, doors, and skylights, under this program. While an NFRC label does not mean a recommendation, it will tell you if a window replacement in Columbia, SC, or the local area, will perform according to your expectations.

NFRC Ratings

When shopping for energy-efficient windows in Greenville, SC, or the local area, it is essential that you have an understanding of what the numbers mean.

  • U-Factor – This measures the heat from inside your home that can escape. The lower the number, the better your window is at keeping heat trapped inside.
  • Solar Heat Gain Coefficient (SHGC) – This can be a number between zero and one. The lower the number, the better your window is at reducing solar heat gain, which is essential during summer.
  • Visible Transmittance (VT) – This measures the amount of light that enters your home. The higher the number, the better your window is in letting natural light in.
  • Air Leakage – This measures the amount of air that enters your home. The lower the number, the better your window is at preventing drafts.
