Tests have shown that Vinybilt's ETI system outperforms other systems with higher Energy Ratings as well as improved U Values and R values.

ETI BENEFITS

  • Improves overall window performance by up to 8% of the overall energy rating.
  • 2 points improvement in ER values when compared to non-foam filled windows (Lab report available)
  • Improves U Values
  • Improves R Values
  • Reduces heat and cold transfer through window sash and frame
  • Reduces window condensation
