Nice work! We went with strips of wood in the valleys. Crazy how many different ways there are to build out an RV van.

 

Crazy how many different ways there are to build out an RV van.

Problem is that many of these techniques and methods are being shared by people with no previous experience and none of them are proven to be successful long term solutions.

Greatstuff is highly flammable and would never pass Federal Motor Vehicle Safety Standards. Click the link below to watch it burn.

That looks great. Thanks for the video.

What's the plan now, plywood or a full foam sheet then plywood?

 

Preferably a one inch sheet of Poly-Iso, but I have a medium roof van and currently I can barely stand up straight (under the roof cross members). Have to skip any more insulation and apply 1/2 inch thick sheet of plywood. It's all about compromises.

The wood that covers the floor and walls also burns so I may need to carry some marshmallows and a stick.

I filled the floor corrugations with 1/2" closed cell foam which is easier than Great Stuff. Did use Great Stuff in the ceiling and wall window indents to glue the rigid polyiso in place.

 

I've tried to ignite Celtec in the same manner and it won't burn or even support a flame. It is self extinguishing. Wood won't ignite nearly as easy as the Great stuff.

Of course we are free to use what ever materials we want in our conversions. But where does that leave the person who decides to purchase our used vans?

I didn't write the FMVS standards. I choose to follow them as much as possible. As writer of an independent build blog, I believe that it is your duty to warn of such things.

 

Since i'm spending 3 hours a day in the van, including NE winter with closed windows, I'll be checking any material for off-gassing.
