That's a pretty cool idea... and an easy DIY with some trashed windows. Cut out the plastic and use silicone seam seal to glue in the mesh on the inside of the window. Trim away the excess once it cures and you're good to go. HD mesh like that used by SpiderWeb for the sun shade is about $15 a yard. Might be able to get away with two (likely three) yards.
Thank you
