Reflectix Material

I have a set of inserts for all the windows. Cut to fit in windows, snug (holds itself).
Used Velcro for door windows.
I used the 24" roll.
They have a silver tape that holds great.
I taped a lot of larger odds & ends to reduce waste.
I remove from windows when not needed. Inserts folds up and is stored behind furniture.

So you used it as toppers on the bunk ends, as well as window inserts. Correct?
what width did you wind up using?
And did you install it inside or outside with the clips?

I have used it, I cut it to fit and used the heavy duty metal paper clips from Office Depot to attach, I also did the windows and only used them when I had a lot of light coming in the bunk areas. I really made a difference with heating and a/c in the pup.
