Reflectix on interior windows?

[AE Wanderer]

We camped in Ridgctest, California, two years ago. Outside temp was 112 in the afternoon, outside. Inside temp would not go below 89, and that was with all 3 roof a/cs going. Went to Home Depot and bought a roll of Reflectix. Cut to fit each window. It lowered the inside temp 12 degrees to 77. Yes, our coach has dual pane windows.

I can easily believe that. We used to cover all the windows in our old single pane coach and it made a huge difference.
