Understanding the NFRC Label: 5 Common Terms Explained

Energy-efficient windows are one of the most sought-after products today. These provide greater energy savings while helping maintain comfort at home. The thing is, not all windows are energy-efficient.

Fortunately, the National Fenestration Rating Council (NFRC) has found a way to ensure the energy efficiency of windows in Wichita, KS. If you see the NFRC label on a window, this means that the product has been tested and rated for energy efficiency. To help you understand how the NFRC label works, we’ve gathered four common terms that are related to energy efficiency:

  1. Visible Transmittance. According to the NFRC, visible transmittance measures the amount of natural light that comes into a room. The higher number on the label means the greater presence of natural light.
  1. Solar Heat Gain Coefficient (SHGC). Another common term on energy efficiency is SHGC. This is responsible in measuring the amount of outdoor heat that comes into a room. Unlike visible transmittance, the lower the number on the label, the lesser chance of wasting cool air.
  1. Air Leakage. This refers to the amount of air that enters the room through the window. If you see a lower number on the label, it means that the product is less susceptible to drafts and condensation.
  1. U-Factor. The heat that escapes inside your room is measured by U-Factor. It checks the rate of heat loss or transfer. The lower the U-Factor number, the less likely you’ll waste heating expenses.
  1. R-Value. This measures the resistance and conductance of a product. The higher the conductance number, the faster it conducts heat.

These terms will help you assess the energy efficiency of your window. We figure that these terms will come in handy when you’re looking for a good replacement window. All States Home Improvement installs energy-efficient vinyl windows in Wichita that homeowners will love.
