Double glasing is done by the Window manufacturer, its 2 pieces of glass with air in between .

So if the Clearvue Windows were set up with double glasing, I would expect the Clearvue glass is the outer pane, and a standard piece of glass for the inner pane.

It would work well in areas that have alot of daylight, but wide temprature swings.

The Laminated Clearvue Glass looks to me to be thick commercial grade glass, with a thick inner core to the Lamination.

This would give it insulating properties superior to thinner laminated glass.
