If not Reflectix, what else would work that would look decent from the outside, and block incoming heat effectively?
No worry of heating the glass or condensation on chilly nights.
I use solid foam insulation, DOW board from H. Depot or Lowes. Yes I know its pink, I had to paint it flat black to blend with my window trim and tint.;) Its inexpensive and easy to trim. Sometimes on some windows I use one sheet other windows I use two to double the thickness. Depends what fits better.
I think the R value is 5 for the 1" board. But using one thickness works fine. It never transfers the cold or heat. It makes a decent difference.
If I decide to use the window in its original form then I simply remove the insulating panel and store it under the mattress where it won't get damaged.
If you decide to do this:
1. Cut a snug piece to fit within the window frame so its held in place by pressure, tape it place or the shade helps to secure it if its snug enough. I cut it a little large then trim it down to fit snug.
2. I cut a 10x10 square in the middle so I could see out. I covered the square with Clear Window Insulating (heat shrink) Film. The window kit includes the sticky tape to secure the film to the DOW board.
3. If you need it to be thicker, then double the board thickness with the square cut-out of it to match the first piece. No need to heat shrink cover the second piece, one layer is enough.
