Interior was completed with ice&water shield, a roof edge and valley rubber membrane self sealing in 3 foot wide rolls. Then 1/4" plywood was screwed to the ribs through the membrane. A second layer of 1/4" plywood was glued to the first with plain wood glue. About 2 gallons total. Roof curve transition is the tough part. Apply saw kerfs 1/8" deep and about 1/2" apart and some kind of jack with a good horizontal brace to force the plywood into the curve. I had two sheets blow out before completing assembly.

This wall will allow you to hang almost anything you want weight wise. And there are no thermal spots on the inside surfaces.

And yes, do fill the beams with foam.
Worked well on two buses.

Good luck,
Bill

Ice and Water shield?  That's awesome.  I never would have thought of using that.

Just to understand how sensitive the camera is, you can touch a wall with your hand for one second and a minute later you can still see your hand print on the wall where you touched it.
The flir camera makes it nice to see the problem areas to work on insulating better.  Umm you can tell the chair I was sitting in until right before I shot the video :) most of my side windows are double pane and The bus was in the barn for the video so no solar heating gain is effecting the results.  I'm sure parked in the sun would look much worse on the flir camera.

Door area and floor in the stair area needs some insulation for sure.

I injected all the roof ribs with foam but still the metal conducts heat itself and it also transfers right to the screw heads :) it's all spray foamed and there is that bubble foil under the plywood ceiling but the camera sees right through it all.   It's a neat tool to have.

Hey Scott, I have been wanting to take the infrared camera to my bus as well. Do you do infrared for a business? Just curios, I am a infrared Thermographer, I work in the electrical field. We do infrared surveys on electrical equipment for our customers.

That's amazing...seriously. Every bus converter needs one of those. What would an image look like if it were cold outside?

Two things, why were your windshields dark? Did you have reflectix or something on them?

Also, this is precisely why I don't want a ton of large windows in our bus....that right there just convinced me even more.

I bought the camera just as a tool for my tool box.  It's got a lot of uses but mostly it's fun.  It's an attachable camera to my iPhone.

That's really nice, I did not know they had them for cell phones. We just got a fluke camera for work. It is pretty nice but our previous camera had much better resolution. It cost 65k when it was new.
