reflextics - well the shiny bubble wrap type stuff

[Snikwahjm]

We spaced screws with washers around the big vinyl frame windows. Then we attached magnets to the edges of the reflectix. This did not work with taping on the magnets. So I sewed covers for the reflectix and sewed on the magnets. To do it over, I would either just make them a bit oversized and cram them in or I would no sew- lay the cut panels on some very light weight fabric. Mark panels where washers and magnets will touch. First cut the fabric an inch or so too big all the way around. Lay panel on fabric. Tape or hot glue magnets to the marked edges of the panels, then pull fabric up and tape to panel. The tape we used was metal looking duct work tape. And it may come unstuck. There is tape made for reflectix. Pull opposite side up and tape. Then tape sides. Magnets will be covered by fabric but it it is light enough weight it should hold. Be sure to test. Fabric can add a bit of weight. That also leaves the reflectix bare on the back to allow them to reflect the sun off the window. The rear and side doors don’t need washers because the frame is metal. The covers can be turned pretty side out/reflectix side in by changing them to the opposite window at least on our van. Test to see what works for you.
