FWIW Airstreams are not particularly thermally efficient. AFAIK the ribs have little to no thermal breaks on them, other than a thin strip of sealant. They will and do transmit heat and cold.

Aaron.
An Aistream shell, has a total metal structure from outside to inside.
The only place sealer is used, is on the seams, but never beteen two metals.
When exterior metal is replaced, at least by a select few, a bead of Vulkem is used between the seams.
However, any thermal insulating gain, would be negated by the rivets.
Separting the outside metal from the inside, using a non conducting material, would be a monumenal task.
Then we would be back to double pane, or true thermopane windows, again.
Maybe some type of composite would work.
