This situation seems murky...
Hi Shane,
I'm told your Matinee (?) product with side tracks has an R5.0 "plus 23%." Is that true? Does that include the R-value of the window? What's the R-value of the window by itself? Have you considered making a higher-R-value product, eg something like the 5-sheet aluminized shade developed by Insulated Shade Co. of Branford, CN in 1977?

Dear Shane,
1.0 per pane x 2 panes = 2.0 for glass
Would you please _look_ at the test report and tell me the R-value of the particular window used in the test, by itself, or send me a copy of the report?
Thanks,
Nick
