LiteZone® was used to upgrade 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.
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. After installing the LiteZone® IGU the overall window insulating value increased from ~R1.5 to R8.5 (from ~R2.0 to R9.6 centre of glass).
The new exterior wood glass stops for the LiteZone® IGU were metal clad for low maintenance.
The renewed window has an overall insulating value ~35% higher than what was possible with a triple pane IGU and the LiteZone® IGU has 3 times the life of triple pane.
