Superplumber_ mi do you have any pictures of how the spray foam turned out? What size PM did you spray?I purchased a two part, mixing spray foam at home store. It has a long enough hose and sprayed great. We sprayed the walls and ceiling. Very quiet and warm. Don't very afraid to spray yourself. Costs about $200.
Hi,Gary, I appreciate your feedback and your reasons for choosing spray foam. I do take issue with the fact that neither you nor ProRam sprayed the ENTIRE cargo area of the van. Therefore your comments about no water vapor causing condensation and rust does not apply. I'm a fan of spray foam and believe it's the best to use for insulation but you can't use it as your ONLY insulation material. As seen in ProRam's job only the obvious sections are sprayed with foam. What about the difficult to reach open areas in the ribs and rear upper space behind the cargo light?
Here's one of the finished spray job, but don't have any of just the 1/2" taped on. I tried the spray adhesive (3M 77) first and it didn't work very well. Tape held it on well enough until I sprayed, which really locked it in.VanShopping I considered the method you described (1/2 rigid to large flat areas) but I would have used spray adhesive instead of tape. Do you have any pics?
