RE; Reflection- Dual pane windows,
Third rig wtth dual pane { thermopane } windows, none had duals in cockpit. Are you sure the cocpit windows are dual??
The reflection may be why manufacturers didn't install.
I have used tint film on cockpit windows and windshield, to eliminate need for sun visors, installers know what degree of tint is legal.
I was looking into dual pane for cockpit area, but with info ,I think I'll settle for installed tinting, it also has an insulating factor.
Hope this helps=== AIME==== AJBJRVERS==
