Performance Notes:

  • Performance results are calculated using NFRC methodology and LBNL Window software, applied to 1/4" (6mm) clear glass and are subject to variations within industry standards and only intended for estimating purposes. This data is provided for informational purposes only and subject to normal manufacturing variances.
  • Performance results for glare and fade reduction are calculated by comparing filmed glass to that of untreated glazing.
