​Use LiteZone® to upgrade old or failed IGUs for improved comfort and reduced energy costs.

The photos below show a failed double pane IGU in a wood window before and after being replaced with a LiteZone® insulating glass unit (controls are at top of slides).
A double pane IGU in a fixed wood window had fogged and needed to be replaced. The failed IGU was removed, and the wood window frame modified to accept a LiteZone® L0499 insulating glass unit. The new exterior wood glass stops for the LiteZone® IGU were metal clad for low maintenance.​
The home owners then replaced all the IGUs in their remaining fixed windows with LiteZone® L0499 insulating glass units.

​After installing the LiteZone® IGUs the overall window insulating value increased from ~R1.5 to R8.5 (from ~R2.0 to R9.6 center of glass). The renewed windows have an overall insulating value ~35% higher than what was possible with a triple pane IGU and the LiteZone® IGUs have 3 times the life of triple pane.​​

The above detail was used to replace the IGUs in this home's existing wood windows with LiteZone® L0499 insulating glass units that are 3.3" thick.
