I was reading Bob's blog post about Richard's van insulation and saw that he had put Tyvek against the metal skin of the van, followed by bubble wrap > Reflectix > 1" styrofoam > NRP board. I'm wondering why one would feel the need to apply a layer of Tyvek beneath the bubble wrap? Wouldn't the bubble wrap itself serve as a vapor barrier? For my insulation I was planning to go with bubble wrap (to serve as vapor barrier and air gap) > Reflectix > 1/2" Polyiso > Coroplast, but if it is worth it to hunt down some Tyvek for the additional layer I will do that. Just trying to plan my layers as carefully as possible to avoid rust/mold issues later on down the road...
I have read up on the subject of insulation extensively and have done my best to search the forums on this so I hope I am not rehashing a question that has already been answered!
