For what it's worth, I put in several layers of double bubble ..

I will try that. Bubble wrap is a lot easier to find than the "techie" stuff.
Thanks

Look it up, bubble wrap has NO insulation qualities. The metalic bubble has a low insulation value but you have to have a inch air space between the outside wall and the metallic bubble wrap.

I used Dow Tuff-R polyisocyanurate insulation board to re-insulate my entire coach - works out to be an R-8ish insulation value from a 1/2” piece and a 3/4” piece sandwiched together to completely fill the area between the channels and body skin.
