Window Ratings 101: The Energy Label
Don’t Miss Out on Superior Energy Savings
Most eco-conscious Little Rock homeowners are well aware of the importance of having energy efficient windows. The windows we carry at Community Builders of Little Rock are some of the more efficient windows in the industry and are capable of saving you an immense amount of energy. Their proven efficiency has been honored by the privilege of carrying the coveted blue Energy Star® label. This symbol signifies that a product has met and surpassed the government standards for energy efficiency. However, some homeowners want to be able to look deeper into a window’s energy ratings. It’s for this reason that the NFRC label is present on all North American windows. This label offers insights into the qualities of a window’s energy efficiency.
What Does it All Mean?
- U-Factor: This rating indicates how well a window retains the heat in your home, which is a direct representation of its ability to protect against heat transfer. Lower ratings on a scale of .20 – 1.20 are ideal.
- Solar Heat Gain Coefficient (SHGC): This number rates how well a window can block radiant heat generated by the sun. A lower SHGC number on a scale of 0 and 1 is better.
- Air leakage: The rating for air leakage tells the homeowner how much air can potentially leak through the hardware of the window. Measured on a scale of .1 to .3, lower numbers indicate less potential for air leakage.
- Visible Transmittance (VT): The potential for “daylighting” is communicated by the VT rating. The potential for illumination of the interior with natural lighting through the window is known as “daylighting” and higher the number between 0 and 1 indicates more daylighting potential.
