Product/How it works:


​LiteZone® minimizes the weight of multi-layered insulating glass units.
The PET films used within a LiteZone® glass unit have negligible weight and are inexpensive compared to glass. Up to 8 intermediate layers of films are used to configure LiteZone® insulating glass units to achieve very high insulating values with a minimal increase in weight and on a cost effective basis.

Because of the extra glass lite, the glass in triple pane IGUs weigh 50% more than the glass in LiteZone® IGUs. After allowing for the extra weight of the LiteZone® fiberglass spacers, in 5' x 8' glass units, triple pane IGUs weigh approximately:
  • 40% more than LiteZone® L0479 glass units (2 films) that have about 25% higher window insulating values;
  • 35% more than LiteZone® L0679 glass units (4 films) that have about 80% higher window insulating values; and
  • 22% more than LiteZone® L1079 glass units (8 films) that have about 250% higher window insulating values.

The extra weight of triple pane windows can make handling them more difficult compared to windows using LiteZone® glass units.
