When insulating a bus, what consideration is given to condensation between skin and insulation? Does spray-on urathane insulation eliminate the airspace so that condensation can not form? Or, does it just hid corrosion problems? What have you used successfully (or unseccessfully)? What are the worst pitfalls? Has anyone tried to maximize headroom by using 1/8" plywood on the overhead against spray-on insulation?
Thanks for any and all ideas. |

Sprayfoam (structural grade) insulation not only eliminates any air space, but adds strength and noise reduction. Before applying sprayfoam, I filled all framing members with canned foam. We did repair or replace any rusted or corroded metal prior to applying foam. I have never heard anyone who used sprayfoam say they would not do it again, but I have heard some who did not use it say they would the next time. Jack |

My wife came home with one demand from the Bus Conversion convention two years ago--spray foam.
I will probably never tell her that I had already reached the same conclusion based on what everyone said about it.
It was not any harder to do than any other part of the conversion (we have done everything ourselves in the driveway). And it was worth it.
This winter while finishing up the interior, I have been able to maintain a 30 degree increase over outside temps with only my two heat strips operating in the roof top air conditioners (that's a total of 3000 watts of heat). On thirty degree days the interior is sixty which is a comfortable working temp. Last winter working on the shell required two convection and one turbo kerosene heaters to keep warm in there.
Several days ago we noticed that we couldn't even hear the 30-40 mph winds blowing outside.
FWIW
