Know Your Windows: Energy Efficiency & NFRC

Window Ratings Detailing Energy-Savings

Your home’s energy efficiency greatly relies on how well your windows perform. For those with outdated or damaged windows, the energy performance is obviously going to be lesser than it would be with modern windows. For situations like this, it’s best to turn to professional replacement window installers like the ones at Ultimate Gutter Guard of Greenville. We have premier window solutions designed to save you more each month by reducing energy costs.

We have variety of window styles that are available with customizable options allowing you to create the perfect look for your home. In addition to the exceptional beauty that new windows provide, they are also designed to use the most current energy saving technologies and have even been Energy Star® certified. This certification means they have proven capable of surpassing the required governmental standards held for energy efficiency. The blue Energy Star® label on all of our windows is a telltale sign; examining the National Fenestration Rating Council (NFRC) label is another great way to determine the energy efficiency of a window.

Keys to Reading the NFRC Label:

  • U-Factor: The U-factor rating tells how well a window can retain heat in your home, which is a direct correlation to heat transfer and how well the window’s build protects against it. Lower numbers between .20 – 1.20 are ideal.
  • Solar Heat Gain Coefficient (SHGC): This number tells you how well the window is able to block UV rays. Protecting against SHGC directly relates to guarding against radiant heat transfer. A lower SHGC number between 0 and 1 means the window performs better with SHGC.
  • Air leakage: The air leakage rating is a measurement of the potential the window’s hardware has for permitting air to pass through it. This is measured on a scale of .1 to .3 with lower numbers indicating less potential.
  • Visible Transmittance (VT): The potential for “daylighting” is measured with the VT rating. Daylighting is the amount of natural light that can pass through to illuminate the interior space and is measured on a scale of 0 and 1. A higher number shows more daylighting potential.

Alleviate the Stress of Window Shopping

Labels like the NFRC and Blue Energy Star® sticker are meant to make the window buying process easier for the consumer. They inform homeowners of a window’s energy-saving qualities with sensible ratings. Often, they take the guesswork out of window shopping and take away the reliance on the word of a salesperson. By just examining the NFRC ratings, the consumer can learn all they need about the window’s energy efficiency.
