I expect that the outer pane of glass will block some UV but expect that you will need to replace the plastic at some point due to clouding.

With my parents place the windows were up under an overhang so they didn't get direct sunlight. The other concern is that there really is no good clear plastic that will hold up to UV damage long term, its going to cloud up. Read the specific service information carefully before you visit a store that offers to cut glass so that you know ahead of time if they sell and cut the type of glass required for your project. Generally when the gap exceeds an inch, convective currents set up in the gap and transfer more heat. One example is that the company may only cut glass for windshields, or windows, or for replacement mirrors. These were definitely not the equivalent of double panes as the space gap between the outer glass and the interior panel was 2 or 3 inches. They did make difference in the amount of drafts coming off the windows on cold days. The biggest limitation was that over the years, there was some distortion in the optics (waves) of the plastic and there was some clouding (but not noticeable to most folks). They weren't sealed but rarely if ever fogged. There was a self stick steel strip applied to the window frame and the window just hung off the steel strips off the magnets. At least 20 years ago they had plexiglass inserts built that had magnetic strips on the edges. It would have cost a fortune to replace with custom double panes and would have messed up difficult to replace trim. Convenient pre-cut sizes typically range from as small as 10 inches by 12 inches up to 30 inches by 36 inches. My parents had an odd sixties contemporary with triangular single panes. Window glass replacement pieces are a common need, and sheets in both 3/32-inch or 1/8-inch thicknesses are usually available to fit a variety of modern and antique windows.
