Let me start by saying we believe that foam insulation is superior to fiberglass in an RV. One of the things that attracted us to the Columbus was the foam insulation. From what I know, there are only two manufacturers that offer decent foam insulation in more affordable RVs (fifth wheels), and that's Palomino's Columbus and the higher end Heartland models. Jayco offers R-21 foam, which I don't think is too good. If someone knows of other ones, please let us know.
While researching the 325RL, I happened across an older post on another forum that indicated that fiberglass insulation is used in the floor of the Columbus. The website says the floor is laminated, so I assumed it was foam just like the roof. Can anyone verify which it is, please? Also, does anyone know for sure if astrofoil is used in the roof and floor or just the floor? From the website, it looks like it's only used in the floor. I do know, from a previous discussion with Christopher Columbus, that astrofoil is used in the slide-out floors.
Thanks to anyone that can help.
A construction cut-away detail on the website would be so helpful.
