on my trailer they used the corrigated metalized mylar for ducts. One, they have lots of airflow resistance and two, not much insulation. I dropped the underbelly and replaced all of that with the same diameter rigid snap together ducting and then wrapped it all with a few layers of the adhesive backed foil insulation.
massive improvement in airflow and temperature.
