​LiteZone
® solves problem of glass lites "kissing" under wind load.

Competing insulating glass units using krypton or xenon gas may reduce the gap between glass panes to as little as 0.25 inches to optimize the thermal performance (i.e. increasing the gap from 0.25 inches decreases the performance). Such a narrow gap creates a potential problem with the exterior glass lite touching, or “kissing”, the next layer of glass or film when a gust of wind momentarily causes the glass to deflect inwards. This is particularly a problem with large glass units because large glass lites are more flexible. Such “kissing” can damage glass or films and can damage low-e coats. This is a serious limiting factor for these glass units, because if the glass unit size must be kept relatively small to avoid 
“kissing” then for a given desired opening the window may need to be divided to carry a greater number of smaller glass units. The increased amount of expensive and energy inefficient framing will reduce the overall insulating value of such a divided window, increase costs, and limit the building’s design.

LiteZone® glass units do not have reduced air spaces and therefore do not have problems with “kissing”. In fact, because they are pressure equalized, LiteZone® glass units can be large which tends to reduce overall window costs because there is less framing required in proportion to the window area.
