had you not tried you wouldn't have known, but at least you tried. Thanks for sharing

That was brave, can't imagine the mess I would make. had enough trouble with the thinsulate.

Don't stress man, either you win or you learn.

I live in Summit County Colorado & worked for a weatherization company utilizing all types of insulation. We have a 2006 Sprinter RV fitted/finished out by Leisure Travel Vans. After discussing ideas with my coworkers, decided to stayed away from foam as didn't want to drill holes in interior walls & it would undoubtedly buckle interior walls & exterior metal skin. Thus, we've installed Roxul, now Rockwool, in all accessible cavities. But, seeking ideas for insulating the remaining cavities ... considering Tiger Foam slow rise or Retro Foam, but can't work up the guts to implement. Anyhow, noticed U2 didn't have appropriate PPE while foaming, strongly encourage it for your next foaming.

Good video Bill, I insulated my van with white styrofoam bead boards rather than Spray foam, which wasn't even available back when I did it. You used to be able to find 2" x 4' x 8' panels at Home Depot etc. Now all I see are 1/2" pink or green panels or silver mylar coated ones. You'd need several layers to fit the 2" deep panel recesses of the van...a bit cost prohibitive, so 2" foam was the way to go at the time. Used some foam spray or pink fiberglass insulation to stuff into places I missed. I had the invaluable help of a "hot wire" foam cutting tool. A 10' wire attached by long leads at each end to a transformer. The wire had handels at both ends, so you and a partner would stand at opposite ends of a foam board (resting on saw horses) line up the streched wire to your pre-drawn marks and with the transformer turned on and the wire glowing red hot, just drop the wire right thru the board like a hot knife thru butter. Made super strait, clean cuts to the various sizes needed to plug into the van recesses. Attached the foam blocks with liquid nails and replaced stock gray plastic panels over the nice flat, flush surfaces. Worked great, lots of little loose beads to vacuum clean out but no masking or cleaning up of sprayfoam overspray. A couple months after doing the job I got rear-ended and had to pull out a lot of the foam so the bodywork could be pounded out. That would have probably been a lot uglier if the foam had been sprayed in type. Anyway, It was a pretty easy job and has lasted 18+ years with no problems.

You know you can use a hot wire to cut it tight. It would be fast and easy.

The trick may be the loss of a few calories of heat and and extra blankie. A live doll with warm blood wouldn´t hurt either. Perfection is elusive. My van has factory insulation that amounts to some plastic cut outs tossed in free and loose between the shell and the camper carpentry.

Bill - one of the big “warnings” I’ve read about spray foam is the “if you need something welded, no one will touch it!” Any thought about that? Another great video! So very much appreciate your sharing!

You have given me some serious ideas on how to do this better. Thanks for sharing your "tried this and that" experience. I have experience in rattle can foam and vermiculite or perlite insulation. Could you try this for viewer benefit next time. Use rattle can foam with a straw can for all of the nooks and crannies first, to eliminate time and mess. Then can foam a line barrier around wiring and door operators, fill those cavities with loose pour vermiculite, the rods should still move, drill some holes above the opening if needed. With that done, mask and string some poly twine tight over the large open panels to foam, to help you gauge how thick your application is going on. Has anyone done a variation of that?

Foaming is an art. Those bottle kits are hit and miss Humidity and temps effect it greatly. Next time use rock wool. More effective and increases sound deadening.

The lady is gorgeous!

Wow, glad I saw this because I am considering doing my own spray foam for a big school bus that we bought. Funny that the foam boards and spray foam didn't work. It sounded like a really good idea to me.

I have read conflicting reports about spray foam. does it hold moisture against the van skin? I am paranoid about using it because of how wet/damp Scotland is, Thanks' for uploading Bill, sometimes showing people your honest mistakes is as good for the learning process as showing the correct way of doing things, I have made hundreds of mistakes on my own build. As ever best regards

Thought this would be ideal for the purpose myself however after ur heads up vidio I will cut out insulation boards. Did u ever find the first contractors ph # which did a gooooood for u. A frustration avoidance video worth its wt in foam LoL. Tanks & ciao

I was definitely thinking about this into the future. Would it have been better to do lighter coats? Did it bubble on the outside metal?

What is the grey material you are using for the van wall panels?

Mr Bill l do have a question : engine head of 2003 is the same ? Of the engine head 2004? On the dodge sprinter 2500 l will like to know your opinion
