There are three variables involved in pinpointing an Power STAR® qualified window:

  • U-Aspect – signifies how easily heat flows via a window. The lessen the U-factor, the additional insulative the window will be.
  • Photo voltaic Heat Get Coefficient (SHGC) – steps the amount of money of heat-triggering light that can vacation into a dwelling via the window. Reduced figures in this article signify that significantly less photo voltaic heat is authorized in.
  • Air leakage rating (AL) – steps the total of air authorized by the body and joints per square foot of window place. Windows with a decrease AL rating let less air to circulation by.
