Awhile back I saw a post on some reflective material to put on inside of widows with some Velcro tabs to hold in place. I was wondering if any of you know where to get the reflective material or know if the material in my picture will work. Thanks
It's called Reflectix, and used alot to wrap home water heaters. Many people who have popups and hybrids will cut pieces to fit into their tent end window areas.
You can find it at home improvement centers, and yes it does work in many applications. You can also cut a piece to fit and velcro them to your ceiling vents from the inside too.
