I don't get your point with the ceiling tho. Use the flexible foam board that everyone talks about for the ceiling to follow the curve of the ceiling. If you want more than the wall/ceiling thickness, then screw your furring strips straight to the hat channel in whatever gives you the final thickness you want. I.e. 3" = 1 1/2 hat + 1" furring + 1/2 semi ridged. Cut down a 2"x4" to your 1", soak in water, bolt to hat channel. A 1" thick piece of pine will bend well enough. Might not even need to soak it.
Glad you like! Me too!!
I included the part about the ceiling because I anticipated someone saying the idea might not work well with it, but I figured I could work with it anyway. Didn't know about flexible foam board though, I'll have to look that up.

And as for leaving the panels on, Nah, I want to add 1/2 inch foamular rigid foam on top of the spray foam, and then my interior walls. But if I wanted to that would be a great idea, mb someone else will do it that way!

Haven't looked into it yet myself but I think it's just 1/4 or 1/2 ridged that is only semi ridged.

Huh? So instead of plywood, use your 1/2" foamular ridged. Screw/glue it to the hat channel and fill as shown. I don't see the point in putting up the plywood just to remove it. Almost anything can be used as the "faceplate". Why not use whatever your wall is going to be. Hell, build your final wall to chest level and fill. When you're done you only have to build the top half.

The point of putting up panels then spraying the foam inside is to minimize waste and save the work of sawing down the extra flush later. I think 1/2 inch foamular would bow out as the foam expands. And the need for plastic is because it would bond to the wood. And the reason for removing the plastic covered plywood is so I can add the foamular after the spray foam, then add walls. It's just the order in which I want my insulation, I won't want to do spray foam, bonded to plywood, then foamular, then wall. I want spray foam, then rigid foam, then mb furring strips, then wall. Or mb Spray foam with rigid foam smushed on top to seal, then more rigid foam, then wall. I agree it would be less work to use whatever you'll use as the wall as your faceplate, but that's not how I wanna layer my walls.

I wouldn't recommend it. Layering rigid on spray has the potential of creating small gaps. That = moisture and that is never good.

That's the big question. Assuming the 1/2" doesn't bow then you'd be golden. It would certainly be worth a trial run in a section. If it does bow, I'm still skipping the plastic. Put up the 1/2" and then the plywood next. Let the spray adhere to the 1/2" and move just the plywood to the next section.

I found a guy in illinois to do my bus with spray foam. I preped it and drove it to his house. 2 days later got my bus back. He did a great job. Its 1 1/2 inches of foam, which the guys said was equivalent to r30. He only charged 750$ to do the foam. Said he'd be willing to foam anyones bus who wants to bring it. In my opinion its the best for the money.

His address and phone number please. If he doesn't want it public, post at least his zip code so we (I) can google the mileage.

Yes, please give me the equivalent of his virtual business card.

Also, I might be wrong, but it seems to me that r30 from 1 1/2 inch of spray foam is stretching the numbers a bit.

That does seem like an exageration from that much spray foam. Technically I've got pretty low R value in my insulation.

The success that many of us have seems to come from the thermal break most of us employ in our insulation process in combination with sealing up all the little holes that allow air to escape. Eliminating the metal surfaces on the interior is at least as important as covering the windows during extreme temperatures.

It's a very hot day here today.

Please PM his contact info, as well. Good price.

I'm also proud to live in the first State in theUnion to go bankrupt....Powerball Lotto is dropping Illinois because they can't pay the winners...
