I'm just getting started with my 2012 Chevy Express 1500 cargo van. No windows in cargo area except rear. I've read a good deal here on the forums but still have questions. I don't want to overthink this too much, but don't want to run into unforeseen problems later on. For the walls and ceiling, the friend that's helping me suggested we go, in order from van skin in, pink rigid foam insulation, plastic sheeting (vapor barrier) and then my choice of plywood paneling. I'm reading a lot about using 1/2"polyiso rather than the rigid foam board. Why is it favored? Is the plastic sheeting a viable barrier?
We do have plans to use polyiso under the plywood on the floor albeit thicker. I plan to try to stay within moderate temps, but as weather's unpredictable, I'm sure there will be times that it will be cooler or warmer than desired. I know I can dress warmer/cooler and I do have two fantastic fan vents already installed.Thanks in advance!
