Triple-Pane Performance on Dual-Pane Units

LoE-i89 on the 4th surface of your windows allows you to get near triple-pane performance in a double-pane unit, and meet the toughest energy guidelines as well. Finally, LoE-i89 can be purchased in hurricane-resistant laminated glass in a variety of shapes and sizes.

Triple-Pane LoE Insulating Glass Options

  • 366 triple (one pane of LoE 366 glass and two panes of clear glass)
  • 366-2 triple (two panes of 366 glass and one pane of clear glass)
  • 66/79 triple (one pane of 366, one pane of 180, and one pane of clear glass)

LoE 366 Neat®*

Keep your exterior glass cleaner, longer. This glazing option is manufactured with a unique titanium dioxide layer that reacts chemically with the sun’s UV rays that causes organic materials that are on the glass to decompose. It works even on cloudy days, as 80% of the UV rays still penetrate the cloud cover. So when it rains, the decomposed dirt no longer clings to the glass and is easily rinsed away leaving the glass clean and your view more enjoyable.
